Title: Pallet Handling Trucks
IPC: B62B3/06
Filed: 1968-12-20
Abstract: 1,186,329. Pallet trucks. EATON YALE & TOWNE Inc. 20 Dec., 1968 [17 May, 1968], No. 60681/68. Heading B8H. Each fork arm 12 of a pallet truck is provided with a ball-shaped roller 24 mounted on a lever 15 which is pivoted at 16 to the fork arm 12 so that the roller can ride on to the lower floorboards B of a pallet P. The lever 15 is formed with an inverted V-section inclined surface 20 on which the upper periphery of the roller rolls rearwardly while the lower periphery rolls forwardly on the pallet boards, the roller axle 23 being mounted in guide channels 22 formed on the lever 15. In operation, engagement of the inclined surface 29 of the lever 15, and subsequently of the roller 24, with the boards B causes the lever 15 to pivot upwardly against the action of a spring 18. Further movement of the fork arm into the pallet causes the roller axle to move down the guide channels 22 against the action of a spring 26, thereby causing the lever to pivot upwardly until a surface 21 thereof engages the underside of the fork arm 12 and thereafter pressing the pallet to the ground and lifting the fork arm and its lifting wheels 13, Fig. 5 (not shown). The fork arm is provided with a similar device to the rear of the wheels 13 and acting in the opposite direction to facilitate withdrawal of the fork arm from the pallet.

Patent GB-2003692-A (GB)
Title: A method of detecting the state of focus of an optical system
IPC: G02B7/36
Filed: 1978-08-24
Abstract: Focus detection is performed in two stages: (a) by a widely spaced group of photosensitive elements 20; (b) by a second closely spaced group of elements 21. Switcher 22 firstly selects group 20 and the illuminance signal providing contrast information therefrom is fed via A/D converter 23 to arithmetic circuit 24 where a summation calculation is carried out to determine the coarse focus condition. Next, switcher selects the signal from group 21 which, after computation in circuit 24 provides a sharply varying detection signal in the region of focus which is used as a fine measurement. Other signal processing arrangements are given, e.g., using a microcomputer. Various patterns of photosensitive elements are disclosed. <IMAGE>

Title: Separating sheets from piles
IPC: B65H3/52
Filed: 1978-11-21
Abstract: A roller system for separating sheets from a pile consists of a feed roller 11 and a return roller 12 which rotate in the same sense. Sheets of paper are drawn from a pile one by one by the feed roller 11 and passed through the gap between the rollers, the sheet being driven by the greater frictional force applied by the feed roller than by the return roller.
