Title: Camera for use with detachable flash apparatus
IPC: G03B15/04
Filed: 1971-06-01
Abstract: 1348553 Photographic camera flash-light apparatus AGFA-GEVAERT A G 1 June 1971 [29 May 1970] 18305/71 Heading G2A A photographic camera having a rotatable socket 2, in which a percussive type or Piezoelectric type flash-cube 15 may be inserted, is provided with means for striking the ignition cartridge (16) Fig.3, 4, (not shown) of an inserted cube through an opening 6, which means comprises a striker member 8; a leaf spring 10 movable between a first range of positions (right hand end thereof below the left hand end, as seen) in which urges the striker away from the opening 6, and a second range of positions (right hand end above left hand end) in which it urges the striker 8 towards the opening 6 to effect ignition; a sliding pin 3 which will alter the spring position when a cube 15 is inserted Fig.3 (not shown) and a release means 11, arranged, when operated, also to alter the spring position, but moving the spring 10 into the second range of positions if, and only if, a cube is attached. As shown, the camera is ready for operation with no cube fitted, and the spring 10 is untensioned and lying within the first range. As the release means 11 moves in direction A, the lug 12 thereof raises the striker member 8 and hence the right hand end of the spring 10, which is thereby tensioned. However, the spring remains within the first range, and thus acts to return the member 8 to the position shown once the lug 12 has moved past the striker member 8. A pin 7 of the member 8 projects briefly out through the opening 6. Insertion of a flash-cube 15 depresses the pin 3, which thereby changes over a lever 13 to set the exposure time for flash, and tensions the spring 10, which remains just within the second range Fig.3 (not shown). Movement of the lug 12 in direction A raises the right hand end of the spring 10 past the dead centre position thereof, and the spring rapidly raises the pin 7 to strike the cartridge (16) Fig. 4 (not shown). Rotation of the cube 15 depresses the pin 7, and causes the spring 10 to move past its dead centre position, thus returning to its initial position.

Abstract: 309,854. Mines Domaniales de Potasse d'Alsace. April 16, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Impact pulverizers. - Material in the form of blocks or grains is crushed by projecting the material from a rotary wheel provided with vanes on to stationary impact plates. The material is fed through a hopper d, on to a revolving disc provided with vanes a, which may be straight or curved and is projected on to impact plates e, Fig. 2, in a normal direction. When disintegrating mixed material the grains having the least resilience will be reduced more completely than the others and can be removed by sifting. The speed of the wheel is varied according to the results desired. The shape of the impact surfaces is the development of a circle of radius R/#2 in which R is the radius of the outer circumference of the wheel.

In a pulse radar apparatus, echoes going to the indicator, first pass through a delay means having a varying delay, decreasing during a first portion of the transmitted pulse interval, and increasing during the remainder of the interval, such that echoes received during said first portion are compressed, and those received during said remainder are expanded. To restore a linear range scale, the indicator is supplied with a time base signal which increases faster than normal for the display of the compressed echoes, and then increases slower than normal for the display of the expanded echoes. The procedure is stated to improve the possibility of detecting echoes in noise at large ranges.

Filed: 1948-07-19
Abstract: 652,067. Automatic temperature control systems. BADER, K. E. July 19, 1948, No. 19279. [Class 38 (iv)] [Also in Group XXXVII] An electric apparatus for type-setting and composing machines comprises two individual thermostatically-controlled heating circuits located inside the melting pot for the type metal, a manually-controlled heating circuit for the mouthpiece of the melting pot, and a bi-range thermostat. The temperatures at which each of the heating circuits are operated may be individually varied. One of the heater circuits carries a heavier load than the other and is adapted to be cut-out at a temperature about 10‹ F. lower than the second circuit. After the initial heating of the pot complete control is assumed by the second circuit, but in tha event of failure of the second circuit the first circuit serves to prevent the metal from solidifying and the pot is not put out of action during repair of the second circuit. The circuits may be operated by two mercury switches attached to thermosprings or by a thermostat as shown in Fig. 2, comprising a rod 2 of negligible co-efficient of expansion and a tube 1 of high co-efficient of expansion. Upon heating, a nut 14 on rod 2 is pulled down upon the ear of two levers 9 pivoted at 8 so that at predetermined temperatures pins 10 of a pair of limit switches 4, 5 are depressed so as to switch off the heating circuits. The temperatures at which the heating circuits are individually operated may be varied by adjustment of screws 12, 13, whilst the working temperature to be maintained may be. adjusted by turning the nut 14.
