Title: Unloading apparatus
IPC: B60P1/16
Filed: 1973-04-02
Abstract: 1429486 Unloading bale waggons SPERRY RAND CORP 2 April 1973 [3 April 1972] 15656/73 Heading B8E A bale waggon 20 comprises a bale loader 36, an unloading table 54, a load bed 60 and a stack discharge rolling rack 70. The loader has guide plates 46, 48 and walls 38, 40 directing bales to a conveyer 44 which feeds them to a table 34 from which they are transferred to the load bed 60 to form a stack thereon. The load bed 60 has a ramp 68, Fig. 2, at its edge which inclines each tier of the stack as it passes over driven by the rolling rack 70 comprising fingers 82 driven in either direction by an hydraulic cylinder 86 acting through a chain-and-sprocket drive 90-98. The unloading table 54 comprises a transverse conveyer 116, Fig. 4, for moving bales of a tier singly off the table and hooks 58 extendable through slots 56 to separate a single layer of a tier for its discharge. The waggon stack unloading operation sequence forming the invention claimed is controlled by handles 32 operating valves in an hydraulic circuit, Fig. 16 (not shown), and which allows the table 54 to be positioned at any desired inclination during discharge of single bales therefrom. In operation a control handle causes the table 54 to rise to a near vertical tier receiving position and when this is reached the hydraulic circuit then causes the rolling rack 70 to advance to cause a single tier of bales to fall on to the table 54 which is then returned to its discharge position. To discharge the table 54 the conveyer 116 is started and this causes the hooks 58 to be extended when paddles 122, Fig. 6, pass from an actuator plate 126 allowing a valve spool 134 to cause actuation of the cylinder 104 to project the hooks 58 which are maintained there by a cam 138 centring the valve spool 134 to lock the cylinder 104 until a cycle of the conveyer 116 discharging a complete layer of the tier is finished and the paddle 122 again restores the spool 134. This cycle is then repeated until all the tiers of the stock are unloaded.

A handle 16 is depressed to move the disc 1 and its support downwardly against a spring 19 in the embossing operation, the depth of the impression being limited by an adjustable stop 18. The disc 1 is accurately adjusted and retained in the required position by a resilient member 24 engaging one of a series of notches in a disc 23, the member 24 being adjustable by loosening bolts 46 to adjust the position of the line of embossing. The strip engages and rotates a knurled wheel 30 as it is moved through the machine, its position being indicated by a disc 31 or by other means. In modifications, the movement of the embossing too's may feed the strip a predetermined distance through a pawl and ratchet mechanism and feed rollers. The strip may be grooved or ribbed and co-operate with corresponding ribs or grooves on the guide plate, and two or more ribs on the guide plate may be provided to form a corresponding number of lines of embossing.

Title: Load responsive power control circuits
IPC: H02P25/14
Filed: 1969-03-27
Abstract: 1,213,091. Control of A.C. motors. ELECTRONIC CONTROL CORP. 27 March, 1969 [1 April, 1968], No. 16007/69. Heading H2J. When the load on a universal motor M increases, the current passing between the control electrode and cathode of a bilateral solid state switch Q2 also increases so that the charging rate of a timing capacitor C2 is advanced. The power supplied to the motor through switch Q1 is thus increased for maintaining the speed. As the motor load decreases, the impedance of the element Q2 increases for retarding the conduction-angle of the switch Q1. The element Q2 may be replaced by other devices whose impedance varies in response to feedback. The initial speed of the motor is set by adjusting resistor R3. Resistors R1, R2, and capacitor C1 provide phase-shift for the timing circuit, whilst a feedback resistor R7 and matching diode D1 are in series with resistors R5, R6. For controlling an induction motor, the motor is connected in the cathode circuit of the switch Q1, and the impedance element Q2 is in parallel with the timing capacitor. Figs. 3, 4 (not shown). The rate of charging of the timing capacitor may be regulated to compensate for changes in line voltage. For this purpose, the capacitor is connected across a trigger diode which is in series with a resistor across the supply-lines, Fig. 5 (not shown).

Class 97(1)  In a microtome having a specimen carrying bar pivoted about a ball and socket or Carden joint for movement past a cutting blade, the bar has a guide surface which slides on a fixed counter-guide surface during the cutting operation. As in Fig. 1, the specimen 1 is carried by a bar 13 which is pivoted about a ball and socket joint in a fixed frame part 5c so that the specimen can be moved downwardly past a blade 2 and then laterally and upwards clear of blade 2 for another cutting operation. For guiding the bar 1 during the cutting operation, the bar is attached at 18, Fig. 4, to a member 19 having a flat surface 19a which slides on a guide surface 20 provided on a frame part 5a, these surfaces 19a and 20 lie in the longitudinal plane of symmetry of the microtome during the cutting operation. Cables 36, 37 extend from the bar 1 to a part 31 and a part 31a, pivoted to the part 31 at 38 under spring action, and press surfaces 19a, 20 together. The vertical and lateral movements of bar 1 are effected by manual or motor drive of a cam disc 43 having two cam surfaces for contact with bar 1 and part 31 respectively. Spinner 1 is moved towards blade 2 after each cutting operation by warming bar 1 either by the hand or by heating coil 14.

Abstract: 317,037. American Cuptor Corporation, (Assignees of Pettit, K. D., Wicks, C. P., and Hajek, M. W.). Aug. 9, 1928, [Convention date]. Fixed-chamber measuring-apparatus with several chambers, valve systems for, and controlling passage of air for.-Coin-freed apparatus for mixing and dispensing beverages comprises separate reservoirs liquids such as syrup and water, separate measuring chambers 75, 76, Fig. 6, for the liquids, and ported plug valves 78, 77 operated simultaneously so that part of the water flows through the syrup-measuring chamber. A pin-wheel 42 moves a sliding rod 45 against the action of a spring, and the rod is held in the displaced position by a detent until released. The rod imparts angular movements of 90 degrees to a disc 57 for operating the valves 77, 78. As the rod is moved to the right by the driving-gear and locked, the valves are turned to admit syrup and water to the measuring chambers. The lock. ing detent is then released by a hand-operated plunger and the rod 45 is returned by its spring, whereby the valves are turned back into the original position and the water from the chamber 76 flows by gravity to the discharge pipe mixing with the syrup and flushing the syrupmeasuring chambers. The water valve 78 is provided with a series of inclined through ports 90 for filling the measuring chamber 76, and one of these ports has a branch 93 through which, in the delivery position, Fig. 15, air is admitted from a vent 94 into the chamber 76. This chamber empties through a pipe 95 leading to the syrup valve 77. This valve, shown in more detail in Fig. 12, is provided with two inclined through ports 79, 80 for filling the chamber 75. These ports are connected at one end by a passage 85 and each has a branch 86 or 87. In the delivery position, water from the pipe 95, Fig. 6, enters one end of the port 79 and passes to the port 80 partly through the passage 85 and partly through the port 86, chamber 75, and port 87. The mixed syrup and water pass from the port 80 to the) outlet. As shown in Fig. 12, the port 86 is smaller than the port 87 and determines the rate of outflow of the syrup whilst the port 87 is large enough to pass the more solid portions of the syrup. For operating the valves from the oscillating disc 57, studs 59, Fig. 6, on the disc carry a slotted disc 100 engaging a key on the valve 77, and studs 106 on the valve 77 carry a slotted disc 105 engaging a key on the valve 78. The syrup reservoir is within the water reservoir and a cooling element is provided in the water reservoir in connection with a refrigerator in the base of the machine. Specification 172,209, [Class 94 (ii), Paper bags &c.], is referred to.
