Title: Improvements in automatic warehousing apparatus
Inventor: RAWLINGS DAVID ERIC JOHN
IPC: B65G1/137
Filed: 1961-07-31
Abstract: 940,170. Controlling dispensing units. SOLARTRON ELECTRONIC GROUP Ltd. July 16, 1962 [July 31, 1961; Oct. 26, 1961], Nos. 27732/61 and 38402/61. Heading A4T. In an automatic warehousing apparatus having a plurality of units dispensing items to means conveying them to an orderassembly point in response to an order fed into a control system, order reading means e.g. 14 for punched cards, set each of a plurality of counters e.g. the one at 18, to a state representing the number of items to be dispensed from an associated dispensing unit, and means for sending a dispensing signal to the units under the individual control of the counters, the signal affecting only units whose counters are not in a datum state, and feedback from the units of the counters so that each counter is shifted progressively towards datum state each time its unit dispenses. The apparatus shown deals with 114 dispensing units conveniently arranged in 19 groups of six, the apparatus relating to each group of six being included in rectangle 10 while rectangle 12 is duplicated six times, one for each unit. A punched card having 114 different three hole positions in binary code is positioned at 14 and a start signal is supplied to control unit 16 so the numbers on the card are read into corresponding counters 18. Completion of this operation is signalled back to the unit 16 which starts a pulse generator 20 and clears a counter 22 whereby up to seven pulses, one per second, are supplied to an amplifier 30 before the counter applies a clamping signal to the generator. The apparatus is meant to dispense up to six items per unit and should a temporary breakdown occur the seventh pulse may overcome it. A more permanent breakdown would be indicated by one of the counters 18 not indicating its datum condition. The output from each amplifier 30 is applied to a gate 34 in each of the six groups 12. If no inhibiting signal is applied from counter 18 via three way gate 36, gate 34 passes the amplifier output through relay 38 to a relay operating a shoot whereby one article is dispensed, to a conveyer belt and operates a mercury detector switch which resets a bistable set 40 initially set by the output from the amplifier and gate 34. Counter 18 counts down one at a time and when it reads nought gate 34 is inhibited and the output from amplifier 30 closed. The detector switch not only operates the count down at 18 but also adds up the total number of items dispensed at 42. a monostable circuit may be used in which the mercnry switch, normally short circuiting a capacitor, is actuated at each dispensing to allow the capacitor to be charged to a triggering level and connected to the reset input of the bistable 40. A master lamp 46 warns the operator of a fault, lamp 48 indicates which group contains the fault and finally the counter 18 which is not at nought more quickly indicates the number of items by which the order is short. Specification 924,703 is referred to.

Abstract: 510,931. Hop and malt extracts and compositions. WOOD, L. D. Sept. 27, 1938, No. 28078. [Class 14 (ii)] [Also in Group III] A hop extract or concentrate is mixed with malt syrup and the mixture emulsified as in a colloid mill. The hop extract is preferably made by extracting the hops with acetone and evaporating the acetone under vacuum.

A dummy projectile for practice ammunition has a thermoplastic shell 10 made from an elastomeric material of high molecular weight the linkage of the molecules being such that it is destroyed by the frictional heat caused by the rifling when the cartridges are fired, so that the shell is weakened and ruptures when leaving the barrel. Suitable plastics are said to be natural and synthetic rubbers, polyethylene and poly-p-xylene and the shell may be formed by injection moulding, presure or extrusion moulding, and other processes. The shell, which may have a driving band 11, is filled with a dense, pulverulent material, which may be in the form of an emulsion. For this purpose, powdered manganese, barium sulphate, aluminium oxide, corundum or iron oxide may be mixed with silicone oil, paraffin, glycerine or saturated oleaginous polymerization products. Wad 15 is of elastic, foamed synthetic resin and the base of the projectile may have a dished closure bearing against wad 15.

Title: Improvements in or relating to change speed mechanism
IPC: F16H33/06
Filed: 1925-11-10
Abstract: 253,416. Manet, W., Claude, R., and Claude, A. July 18, 1925, [Convention date]. Variable-speed ratchet gearing comprises a spring link or connecting-rod B which yields so as to render the speed ratio automatically variable according to the load. A driving-shaft A carries a crank or eccentric A<1> connected by the link B to a loose arm or frame F, which carries two oppositely-directed spring pawls e<1>, e2. The pawl e<2> engages a ratchet wheel C fast on the driven shaft C<1>. The pawl e<1> engages ratchet teeth D in a fixed casing. For light loads the arm F and ratchet C are carried round with the crank, turn for turn. When the load is so great that the crank will extend the spring and pass its lower dead centre, there is lostmotion, but a driving impulse in the direction of the arrow is imparted to the ratchet C. The amount of lost-motion increases with the load, the speed of the driven shaft decreases. When the crank has passed the dead centre, the arm F is kept by the pawl e<1> from moving rearwardly, and the energy stored in the spring B is restored to the driving-shaft. A plurality of such gear units in multiple phase may be employed.

Title: Improvements in or relating to auto-transformers having a variable transformation ratio
IPC: H01F29/12
Filed: 1931-10-12
Abstract: 388,473. Regulating transformers. WEST & CO., Ltd., A. and BERGMANN, F., Brighton. Oct. 12, 1931, No. 28289. [Class 38 (ii).] In a variable-ratio autotransformer, the winding is arranged in two parts on a fixed core element and the relative inductance of the two parts is varied by adjustment of a movable core element carrying a short-circuited winding. In one form, Fig. 1, the winding parts 6, 7, connected at their ends X, Z to a supply, and at one end and a centre tapping Y to the load, are arranged on the outer pair of three polepieces cooperating with a rectilinearly movable core element 5 carrying a short-circuited winding 8. In modifications, Figs. 2 and 4, each part of the winding on opposite sides of the tapping Y is divided into two coils arranged on diametrically opposite polepieces 1, 11, 3, 3<1> on a circular yoke co-operating with a rotatable core element 5 carrying short-circuited windings 8. In the arrangement according to Fig. 2, unwound polepieces 2, 2<1> are provided to form return flux paths as in Fig. 1, whilst in the arrangement according to Fig. 4, such polepieces are dispensed with, the flux threading one diametrically opposite pair of coils being increased and the flux threading the other pair being decreased in accordance with the angular setting of the rotor carrying the short-circuited winding. The transformer may be used as shown in Fig. 5 for diverting current from one tapping to the next on the tapped winding of a main transformer to be regulated. Alternatively, it may be used as a transmitter for operating a remote position indicator, a voltmeter connected across one part of the winding, an electromagnetic device responsive to the difference in voltage in the two parts of the winding, or a second similar autotransformer arrangement being employed to indicate the setting of the movable core element.
