This is a summary of recent congressional actions not reported elsewhere in The Post. HOUSE Police Protection

The House approved, 400 to 21, a measure that would ban manufacture, importation and sale of armor-piercing bullets. Fashioned from one or a combination of seven metals, the bullets have been labeled "cop killers." Violations could result in five years in prison or a $250,000 fine.

The measure prohibits the "willful" sale of armor-piercing ammunition by licensed dealers, provided the dealer has received Treasury Department notice that the ammunition can pierce armor.Violators risk revocation of their licenses.

The "willful" provision protects dealers who might unknowingly sell the ammunition in unmarked boxes. The measure would not ban shotgun shot complying with state and federal law, or bullets designed for target-shooting or sporting purposes. (HR3132, Dec. 17) Judicial Improvements

By voice vote, the House approved a measure increasing the existing annuities program for survivors of federal judges from 4.5 percent of salary to 5 percent and the federal contribution levels by an amount said to maintain the programs' actuarial integrity.

The increased contributions would be used to improve the benefits of survivors and to create a floor and higher ceiling for benefits. In addition, the bill provides for judicial review of Federal Maritime Commission and Maritime Administration orders. It further allows judges to be reimbursed for necessary travel and subsistence expenses while working away from their offices.

The director of the Administrative Office of the U.S. Courts will develop regulations governing reimbursement with Judicial Conference approval. Judges, however, may still choose a per diem allowance for travel. The Senate has yet to take action on the measure. (HR3570, Dec. 16) Small Business

By voice vote, the House approved a measure that would extend, through fiscal 1988, two Small Business Administration pilot programs designed to aid businesses owned by socially or economically disadvantaged persons. The measure extends a procurement program that sets aside government contracts for such businesses.

In addition, the legislation continues a bond-waiver program, established to give the SBA authority to waive posting of bonds for disadvantaged businesses. The pilot programs were established under a 1978 law. (HR2787, Dec. 16) Hamilton Jordan

The House approved, 347 to 40, a measure paving the way for the government to assume the legal fees of former White House chief of staff Hamilton Jordan, earlier investigated for cocaine possession.

The measure would let Jordan, who served under President Jimmy Carter, petition federal court for $67,553 in legal fees incurred following the drug charges in 1979. A special prosecutor and a grand jury subsequently cleared him.

An amendment to the Ethics in Government Act, passed after Jordan's case, would allow those investigated under the act to be reimbursed for legal fees. The legislation would allow Jordan to make a claim under that 1984 amendment. (HR3363, Dec. 17) BOTH HOUSES Survivors' Benefits

The chambers approved a measure that would aid dependents of the 248 members of the 101st Airborne Division killed in a plane crash. The bill allows dependents living at Fort Campbell, Ky., to remain there an additional 90 days. (HR3974, Dec. 19)
