Abstract: 885,476. Load handling attachments for tractors and fork lift trucks. WOODWARD, K. F., and BARFORD OF BELTON Ltd. Sept. 22, 1960 [July 31, 1959], No. 26340/59. Classes 78 (3) and 78 (4). A tractor attachment, for lifting bales, sacks and crates, comprises a pair of gripping gates 3 pivoted at 5 to a main frame 1 which is in turn pivoted at 2 to a second frame 1a adapted to be lifted by power-operated members 1b on the tractor. In operation, the gates 3 are aligned with a bale to be lifted, the members 1b are operated to lift frame 1a, and a cord 13 is pulled to release a gate latching mechanism 12, 10a, thus allowing tie bars 8 to exert a pull on their pivoted connections 7 to arms 6 rigid with the gates 3 which are thereby moved into engagement with the bale. A second latch 10b engages over pin 12 to hold the gates in their gripping position. In an alternative arrangement (not shown), the gates 3 may extend to the left of the pivots 5 and engage arms connected to a rotatable vertical rod to which the lifting force is applied by means of cranks. The device may also be adapted to be mounted on a fork lift truck.

Title: Apparatus for the separation of over-filled filling material from the vacuum circuit of a differential pressure filler for liquids
Inventor: GEILER KLAUS
IPC: B67C3/16
Filed: 1969-05-23
Abstract: 1,261,580. Bottling. KOMBINAT NAGEMA VEB. 23 May, 1969, No. 26463/69. Heading B8T. A rotating table vacuum filling machine has a double chamber pressure equalization device for transferring excess filling material in a container 29 from the vacuum system into the filling material space 30. The chambers 15, 16 of the equalization device are situated one above the other inside the filling tank 5 and rotate with the machine. The upper chamber 15 is connected to the vacuum system via a conduit 9. Each chamber has liquid outflow openings 20, 21 and radially outwardly from these, air inlet pipes 22, 23 all opening into the space beneath their respective chamber. Against the underside of each chamber, fixed to the non-rotating central pillar are flexible sealing plates 24, 25. The plates are semi-circular with a triangular extension based on the diameter and the triangular extensions of each plate point in opposite directions, Fig. 2 (not shown). As the machine rotates the opening and pipe in say the upper chamber 15 sealed by the semi-circular part of the plate 24 will approach the trailing edge of the triangular extension. The radially outward pipe 22 will be opened first. At the same time the pipe 23 will be closed. The two chambers will consequently both be evacuated so that, when on further rotation the outflow opening 20 moves away from the plate, excess filling material passes into the lower chamber 16. Further rotation through 180 degrees causes the opening 20 and the pipe 22 to become sealed and pressure equalized between the lower chamber 16 and the space 30 before subsequent emptying of the filling material back into the tank 5.

Abstract: 1,075,176. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 29, 1964 [June 28, 1963]. No. 26780/64. Heading H1K.  A tunnel diode with a V-I characteristic of the general form shown in Fig. 7 is made by a two-stage alloying process on a heavily doped, e.g. 0À006 ohm/cm., but non-degenerate germanium body. In the first stage, a sphere of lead-antimony alloy (2% by weight antimony) is alloyed to it at a temperature of 750 C. sustained for 2 hours in a hydrogen/nitrogen atmosphere. After cooling slowly a smaller sphere of lead-gallium alloy (0.2%[ gallium) is placed on the remains of the first sphere, alloyed for 1 hour at 650 C., and then slowly cooled. After etching the device has the illustrated I-V characteristic between electrodes attached to the body and sphere residue respectively, the positive quadrant corresponding to a positive potential on the body electrode. This is attributed to formation by impurity segregation of a pair of PN junctions during the second alloying stage.

Apparatus fitted to hay forks.-In a foldable weighing device of the kind wherein one part is used as a handle from which a balance forming the other part can be suspended the handle part consists of a spiked leg fitted with handle grips and adapted to support the balance while resting in an inclined position on the ground. As shown, a tubular member 8, provided at one end with a hay fork or the like, and at the other end with a load-carrying hook 13, is guided for sliding movement within a semi-cylindrical part 2 by means of rings 7 and pins 10. Springs 11 secured to the pins 10 support the tube 8 by means of pins 12. When the tube 8 moves downward against the resistance of the springs a rack 19 on the tube rotates an indicating pointer 22 over a dial 23. A member 1 furnished with handles 3 and with a supporting leg 4 is pivoted to the part 2 by a screw 6 and may be folded against the part 2 to form a handle for manipulating the hay fork. In the closed position of the parts 1 and 2, the tube is locked by a notched plate 17 and the two parts are locked together by a spring bolt 25. In a modified construction, instead of using springs 11, the tube 8 is connected by a steel wire to a sector forming part of a pendulum-weight lever the elevation of which resists and balances the applied load. The weight indications are marked on the sector. In using the devices for proportioning different kinds - of fodder according to requirements, the device is extended as shown in the Figure and the load on the hay fork is ascertained from the dial; afterwards by using the hook 13 the weight of fodder in a pail is likewise ascertained.

In a yarn doubling &c. machine of the type in which each spindle unit is mounted in a swivelling arm which is moved in one direction to press the spindle wharve against its driving belt and in the opposite direction to withdraw the spindle from the belt and bring it into engagement with a brake, each spindle unit can be moved by a pedal operated part and a transmission cable or the like to a fixed position with its wharve in engagement with its driving belt so that the pressure between the wharve and the belt has a predetermined value, the spindle unit being held in such position by a trip latch of an automatic knock-off mechanism which releases the latch when an end breaks, the pedal and associated parts being returned by spring pressure to a position in which the spindle unit can move clear of the driving belt and against the brake. As shown, the spindle a is mounted on a swing bracket b in the usual manner. The spindle wharve h is held in contact with the driving belt i by means of a wire k fastened at one end to pin n on the bracket b and passing over a pulley m and fastened at the other end to a bracket j. Also on the bracket j is a vertical wedge-shaped cam member o which can cooperate with a lug-like part on the bracket b to move the spindle wharve away from the belt i and into contact with the brake pad g. The bracket j is connected with the usual automatic stop motion mechanism comprising a rod q to the upper end of which is fitted a latch block r with which engages a latch s on the stop motion device t comprising the usual drop wires or the like. The latch s maintains the bracket j in the operative position but should the yarn fail the latch s is moved clear of the block v and the bracket j moved upwards under the action of spring w, the cam member o causing the wharve h to be moved away from the belt i and into engagement with the brake pad g. A treadle on the rod u is provided to reset the mechanism.
