Title: Pallet
IPC: B65D19/00
Filed: 1972-11-29
Abstract: 1382737 Load handling pallet E HAFNER 29 Nov 1972 [29 Dec 1971] 55097/72 Heading B8H A load handling pallet comprises upper and lower decks 1, 2 each with integral spacers 3, 4 which have complementary recesses 24, and projections 23 on their respective adjacent surfaces to form interengaging surfaces extending along a radial line 6, 7, 8 from a common central axis 5 normal to the upper and lower decks. The said interengaging surfaces thus allow differential expansion along the radial lines but restrain the decks against relative movement perpendicular to the radial lines. In an alternative embodiment, Fig. 7 (not shown), a rib (19) and a corresponding recess (20) are disposed on each side and parallel to the radial line through the respective spacer. In a further embodiment, Fig. 10 (not shown), the ribs (19) and recesses (20) are replaced by groups of serrations. An elongate slot and a hole 22 in the adjacent surfaces of the spacers receive a bolt 26 for securing the decks together and reinforcing ribs on the upper deck extend in a radial direction from the common axis.

Abstract: 1486629 Recoil modifying SARMAC SA 24 Dec 1974 [28 Dec 1973] 55709/74 Heading F3C A firearm has a barrel carried by a stock into which the barrel can be retracted from an extended firing position to a retracted carrying position, the stock carrying a recoil brake for braking recoil of the barrel relative thereto when a shot is fired and a manually operated connection device between the barrel and the recoil brake which can be disconnected to allow the barrel to be retracted. The connecting device has a connector 1, Figs. 1 and 2, which is integral with the barrel 2, is formed to receive a stop 3 pivoting about an axis 7, Fig. 5, and has an axial bore 5, Figs. 3 and 4, for receiving a rod 4 therein, the latter being attached to a piston (not shown) of an oleopneumatic brake. When the stop 3 blocks the bore 5 the rod is prevented from passing through the connector 1 so that, on firing the firearm, the barrel and the connector are driven rearwards against the urging of the brake. When the rod 4 is driven forward by the brake, the barrel and the connector are returned to their forward positions. A key 8, Fig. 3, is provided for moving the stop 3 from the connected position shown in Fig. 5, where the stop is urged by a spring 6, to a disconnected position as shown in Fig. 4 where the rod can enter the bore 5 of the connector 1. The barrel and the connector can then be pushed rearwardly to the position shown in Fig. 2. The barrel 2 can be locked in its retracted position by a portion 16, Fig. 9, of a serrated wheel entering a notch 17 in a flash arrester 18, for example, attached to the barrel. The wheel is rotated manually to the position shown in Fig. 10 to align a clearance 19 therein with the notch 17 of the arrestor 18 and thus unlock the barrel. In a modification the barrel 2 may be locked by manually rotating a member 20 to the position shown in Fig. 11 where it engages a notch 23 in the barrel. Unlocking is effected by moving the member 20 to the position shown in Fig. 14.

The grain may be of pure alpha-aluminium oxide or alphaaluminium oxide with titanium oxide and/or chromium oxide and/or zirconium oxide. Preferably the melt is thermally insulated by a layer of alumina, coke breeze of an insulating material over the layer of molten abrasive.

Abstract: 1384810 Cameras K VOCKENHUBER and R HAUSER 11 Dec 1972 [9 Dec 1971] 57091/72 Heading G2A A camera has a grey filter spot which is inserted in the photo-taking beam when high speed film is used without flash and is removed from the beam when low speed film and/or flash is used. The filter may be controlled by tactile cartridge codings, insertion of a flash unit and/or by a meter measuring the spectral composition of the exposing light. As shown, a camera for use with film intended for exposure with artificial light has a grey filter spot 14 formed on a spectral conversion filter 8 mounted on a support 7 for movement behind a diaphragm 4, 5. Insertion of a flash unit leg 15 moves support 7 to shift both filters 8, 14 out of the taking beam. If no flash unit is attached, conversion filter 8 remains in the beam to allow daylight exposures to be made and its exact position is determined by a tactile coding sensor 12 so that grey filter 14 is located in the taking beam when high speed film is used. Fig.3 (not shown), shows a similar filter arrangement for cameras using daylight film.

Title: Precision speed switch control
IPC: G01P3/46
Filed: 1978-10-04
Abstract: A speed switch control comprises a permanent magnet AC generator 11 generating an AC signal varying in amplitude with shaft speed variations; the AC signal is rectified and compared at 12A with a regulated DC reference to generate first and second threshold signals indicative of shaft speeds over and under a critical value. A switch actuator circuit 21A develops "on" and "off" switch actuator signals, from the threshold signals to actuate a two-terminal semiconductor switch 13A between on and off conditions; the "off" signal is continuous but the "on" signal is a high-duty-cycle semi-continuous signal including brief recurring "off" intervals. A power storage/supply circuit 22A, connected in parallel with the switch terminals, which recharges during switch "off" intervals, affords the power supply for the threshold and switch actuator circuits 12A and 21A. The switch 13A opens or closes the circuit to a load 18 which may be an alarm, an interlock mechanism to prevent shifting the transmission of a vehicle into reverse whenever the vehicle is moving forwards, or an interlock to close or prevent opening the door of a passenger vehicle whenever the vehicle is moving above a critical speed. <IMAGE>
