Title: Improvements in shutter release mechanisms for photographic cameras
IPC: G03B9/08
Filed: 1960-04-28
Abstract: 906,467. Shutter release attachment for photographic cameras. RUSSELL, C. H. March 30, 1961 [April 28, 1960], No. 14953/60. Class 98 (1). A shutter release attachment for a photographic camera includes a spring-loaded plunger actuating the shutter release mechanism in the camera, an electromagnetically-operated release mechanism for said plunger, an electrostatic charge storing device in circuit with the energizing coil of the electromagneticallyoperated plunger release mechanism, input connections for a source of electrical energy for charging said electrostatic device, and means for discharging said device through the energizing coil to release the spring-loaded plunger. As shown, the outer sleeve 22 of an antinous shutter release cable is secured to a U-shaped bracket 18 and the inner member 12 of the cable is attached by a pin 13 to a plunger 10 slidably mounted in the bracket. By withdrawing the plunger against the compression spring 44, the plunger is latched as shown by a finger 36 on a spring steel strip 38 arranged to be attracted towards the coil 26 of an electromagnet when this is energized. The plug connections 28, 30 to this coil are inserted into sockets 52, 54 connected to a circuit for charging a condenser 60 and including a battery 58. When the charged condenser is short-circuited through the coil 26, as by closing switch 62, the discharge current trips the latch so that the plunger 10 operates the shutter release cable. Instead of the switch 62, a photo-electrically operated relay may be caused to close the contacts 64.

Abstract: 1,159,913. Valves. A. S. VOLPIN. 3 April, 1967 [17 June, 1966], No. 15076/67. Heading F2V. The rotatable conical plug valve is automatically supplied with lubricant sealant to the working faces by opening and closing the valve. The sealant is filled into a reservoir above a piston 25 through an actuating stem 24 carrying the piston. In closed position, upstream pressure leakage into the plug bore 18 has access to opposite ends of the plug and to piston 25 and sealant is forced through two check valves 61 into two sets of grooves encircling the upstream and downstream flow ports. A set of grooves comprises three grooves (51, 52, 53), Fig. 5-7 (not shown) in the plug which encircle a port on three sides, and a fourth groove (54) in the seating which registers with a short portion (55) extending from the side of groove (51) at one end. The top groove (51) is extended past the longitudinal groove (53). In open position this extending portion registers with the seating groove (54) to replenish sealant flushed out of this groove. A stop arm 43 on the stem limits the angular movement to 90 degrees and also indicates the position of the piston 25.

Title: Vehicle crash recorders
IPC: G01P3/489
Filed: 1973-03-29
Abstract: 1371185 Vehicle crash recorder GENERAL MOTORS CORP 29 March 1973 [3 May 1972] 15100/73 Heading G4H In a vehicle crash recorder, analogue information signals are periodically sampled and each sample coded into a serial digital word which is stepped through a shift register having a number of stages equal to the number of bits in a given number of words, and after a crash a number of words other than said given number are shifted into and/or through the register whereby at least a portion of the words in the register prior to the crash provides pro-crash information and at least a portion of the words supplied to the register after the crash provides post-crash information. The circuitry is all solid state. As shown, longitudinal acceleration and sideways acceleration signals are obtained at 10 and 12, respectively, and amplified in low-gain amplifiers 16, 22 and high-gain amplifiers 18, 24. The amplified signals are sampled in turn and coded at 40, the "low-gain" signals being clocked into register 42, the "high-gain" into register 44 Speed dependent frequency signals, obtained at 26, are coded by counting and clocked into a register 48. When a crash is detected by level detector 50 no further words are supplied to registers 44 and 48 which retain the pre-crash information already therein. Switch 52 is enabled and as post-crash information is clocked into register 42 the pre-crash information already therein is transferred to a memory 53. This continues until all the pre-crash and a predetermined number of post-crash words have been transferred to the memory 53. Thereafter the contents of registers 44 and 48 are transferred in turn to the memory 53 and the power supply disabled to prevent any further information being monitored.  Driver response and brake energization may be monitored. If the shift registers 42, 44, 48 are non-volatile, memory 53 may be omitted.
