Abstract: 1448480 Impelling tools OLIN SKI AG 21 Dec 1973 [28 Dec 1972] 59409/73 Heading B4C [Also in Division F3] A striker mechanism comprises a striker 12, Fig. 1, which is slidably mounted in a bore 8 of a member 4 and has a pin 11 extending from one end thereof, said pin being slidable in a bore 7 of the member 4. The bores 7 and 8 are connected by a tapered bore 9 and passages 14 are provided between the striker 12 and the member 4. The passages 14 may be formed in the striker or in the bore 8 of the member 4. A chamber 5 is formed between an end of the member 4, which is received in a barrel 1 of a gun, and a partition formed in said barrel 1. The chamber 5 receives a caseless propelling charge (not shown) therein which, when hit by the pin 11 of the striker 12, forces pressurized-gas through an orifice 6 to move a piston 3 in the bore 2 of the barrel 1 and thus fire a wall plug for example therefrom. Pressurized-gas also urges against the pin 11 to return the striker 12 and then passes through the passages 14 in order to effect damping of the striker by pressing at the end thereof which is remote from the pin 11. The latter, which may be made from spring steel, may be mounted in the striker 12 as shown in Fig. 2.

Title: Optical sensing arrangements
IPC: G02B7/36
Filed: 1970-12-17
Abstract: 1334231 Photo-electric focusing RICOH KK 17 Dec 1970 [31 Dec 1969] 59865/70 Heading H4D [Also in Division G1] A sensing element Q 1  for use in an array of identical parallel-connected elements comprises a pair of silicon solar battery cells D 1 , D 2  connected between terminals X and Y with their polarities reversed relative to each other. If the cells D 1 , D 2  are equally illuminated no output is produced between terminals X and Y. If, however, cell D 1  is more strongly illuminated than cell D 2  a positive output will be produced at terminal X if terminal Y is earthed. Thus the output of the array of identical elements is greater for a sharply focused image projected on the array by a camera lens than for an out of focus image. The resulting output is amplified and used to trigger a control circuit if it is greater than a certain selected value.

Title: Winch drive
IPC: B66D1/74
Filed: 1978-07-26
Abstract: A manually powered multi- speed winch has a drive between a shaft and the drum (11) which is automatically disengaged upon drive reversal. The winch can be set to a first drive ratio, of least mechanical advantage, by a control knob (85) accessible at the outside of the winch. The knob is lockable to override the automatic disengagement. Locking is by engagement between a pin (86) and the transverse extension (90) of an L- slot in the stem (80) of the knob (85). A stirrup (71) is thereby held downward and an axially movable drive member (35) upward to maintain unidirectional drivable connection between the shaft and itself, through pawl and ratchet arrangement (60, 63). With the knob thus locked first reversal engages a second drive ratio and second reversal returns the winch to the first drive ratio. <IMAGE>
