After World War I the US Army started developing a dual-role (AA/ground) automatic 37 mm cannon, designed by John M. Browning. It was standardised in 1927 as the T9 AA cannon, but trials quickly revealed that it was worthless in the ground role. However, while the shell was a bit light (well under 2 lbs) it had a good effective ceiling and fired 125 rounds per minute; an AA carriage was developed and it entered service in 1939. The Browning 37mm proved prone to jamming, and was eventually replaced in AA units by the Bofors 40 mm. The Bofors had attracted attention from the US Navy, but none were acquired before 1939. Also, in 1931 the US Army worked on a mobile anti-aircraft machine mount on the back of a heavy truck having four .30 caliber water-cooled machine guns and an optical director. It proved unsuccessful and was abandoned.
What replaced the Browning 37nn because of jamming issues?
****
The answer: Bofors 40 mm

The Pro Electron standard, the European Electronic Component Manufacturers Association part numbering scheme, begins with two letters: the first gives the semiconductor type (A for germanium, B for silicon, and C for materials like GaAs); the second letter denotes the intended use (A for diode, C for general-purpose transistor, etc.). A 3-digit sequence number (or one letter then 2 digits, for industrial types) follows. With early devices this indicated the case type. Suffixes may be used, with a letter (e.g. "C" often means high hFE, such as in: BC549C) or other codes may follow to show gain (e.g. BC327-25) or voltage rating (e.g. BUK854-800A). The more common prefixes are:

Victoria's self-imposed isolation from the public diminished the popularity of the monarchy, and encouraged the growth of the republican movement. She did undertake her official government duties, yet chose to remain secluded in her royal residencesWindsor Castle, Osborne House, and the private estate in Scotland that she and Albert had acquired in 1847, Balmoral Castle. In March 1864, a protester stuck a notice on the railings of Buckingham Palace that announced "these commanding premises to be let or sold in consequence of the late occupant's declining business". Her uncle Leopold wrote to her advising her to appear in public. She agreed to visit the gardens of the Royal Horticultural Society at Kensington and take a drive through London in an open carriage.
Where did a protector put a notice because of Queen Victoria's lack of public appearances in March of 1864?
****
The answer: Buckingham Palace
