Abstract: 1,065,512. Moulding pies. J. J. ZONES. Feb. 23, 1965, No. 7750/65. Heading B5A. Pies are made by feeding a continuous sheet of dough on to a series of moulds carried by an endless belt, each of which moulds comprises a front plate 42, carrying two mould cavities (44), hinged to a rear plate (56) carrying parts which co-operate with the peripheries of said  mould cavities. The sheet is first divided by passage between a spring biased roller arrangement 106 and blades (not shown) carried between the moulds, after which filling material is deposited into the mould cavities 44 by a dispenser 30. Plates 56 are then pivoted into overlying engagement with plates 42 by cam mechanisms 64, 80 and the two plates pressed firmly together by the subsequent passage between a lower wheel (not shown) and a spring biased upper wheel 90. The overlapped sheets of dough are then pressed together about the peripheries of the mould cavities to form filled closed pies which are simultaneously severed from the excess dough. The plates are finally re-opened by a second cam means (not shown) and the pies removed in a suitable manner.

Patent GB-590237-A (GB)
Title: Improvements in or relating to spring catches
IPC: B61G7/00
Filed: 1945-03-29
Abstract: 590,237. Spring catches ; hooks. ENGLISH STEEL CORPORATION, Ltd., and WHITEHOUSE, G. D. March 29, 1945, No. 7961. [Classes 44 and 89 (ii)] [Also in Group XXXII] A spring catch, providing means for engaging and releasing an article by merely pushing and pulling it, comprises a hook with a rocking latch having setting and retaining arms and two mutually-inclined faces engaged by similar faces on a spring-pressed plunger. The catch is particularly applicable for holding the coupling link of a mine car or railway waggon in an inoperative position, but may also be used for doors, lids and the like. In the example shown, a mine car is fitted with a hook body comprising a coupling hook 13, an anchoring slot for a link, and a buffer head 16 extending in front of and below the hook 13. The anchoring portion 17 is swivelled to a coupling portion 21, and hooks into the anchoring slot, the entrance to which is slightly narrower than the flattened or oval part of the portion 17 which is in the slot, so that accidental detachment of the link is unlikely ; the main portion of the slot is wide enough to allow the portion 17 to swing freely. When not in use, the link 15 is held clear of the hook body by a catch 41 secured to the car body vertically above the anchoring slot. The catch comprises a jaw or hook 42 forming a recess 43, a rocking latch 44 pivoted to the body of the catch at 50 and having a retaining arm 45 and a setting arm 46, and a plunger 47 normal to the axis of the pivot 50 and urged by a spring 48 into contact with one or other of the inclined faces 51 of a projection 49 on the latch 44. When the setting arm 46 lies across the entrance of the recess 43, the coupling portion 21 may be lifted into this entrance causing the setting arm to rock the latch about its pivot 50 ; the projection 49 rides up one inclined face 51 of the plunger and is then held down by the other inclined face, bringing the retaining arm 45 across the entrance. To remove the link it is forced against the retaining arm 45 and lifted over the hook 42 ; the setting arm 46 is thus returned by the rocking of the latch to the entrance of the recess. The latch lies mainly in a slot in the body of the catch formed between side walls through which the pivot pin 50 passes. Specification 590,238 is referred to.

Title: Improvements in or relating to grinding methods and apparatus
IPC: C09C3/04
Filed: 1963-02-28
Abstract: 961,519. Grinding; mixing. STECCO S.A. DE TECHNIQUE CHIMIQUE. Feb 28, 1963 [March 5, 1962], No, 8140/63. Headings B1C and B2A. A method of grinding solid particles, e.g. pigments, in which the material to be treated is passed a number of times through a grinding machine is characterised in that the successive passes through the grinding machine are carried out in continuous movement on the whole of the material treated, without intermediate extraction, and in that the succession of passes is effected by automatic means in accordance with a predetermined programme. Apparatus for carrying out the method comprises a grinder 1, a pre-mixing tank 2, a re-cycling tank 3 and a finishing tank 4, a suspension of the material to be ground being passed a number of times from tank 2 to tank 3 and from tank 3 to tank 2, with intermediate grinding in the grinder, until the desired fineness is obtained at which time the treated material is directed into tank 4. The grinder has associated therewith a tank 21 provided with a filter 23. The tanks 2, 3, 4 are provided with motor-driven agitators 8, 10, 12 respectively. The circulation of the suspension is effected by motor-driven pumps 24, 25 in association with piping and valves. The valves are controlled by electric relays operable by contacts 55, Fig. 4, actuable by cams 50 to 53 on a shaft driven by motor 49. The initiation and control of operations is effected from a control desk 43, Fig. 1 (not shown). The cycle of operations and control of circulation are operated by electric probes 44 to 48. Probes 44, 46 control the starting of motor 49 when the level of the suspension in tank 2 falls below that of probe 45, the latter operates to stop the agitator 8. When the level in tank 2 falls to that of probe 44, the programming device comes into operation and reverses the circuit. This causes valves 30 and 41 to close and valves 31 and 40 to open. When level in tank 3 falls to that of probe 46, the latter initiates the reversal of the circuits. The suspension in tank 2 is first deflocculated by running the agitator 8 at high speed and then at low speed before finally stopping it. Examples are described.

Title: Means for keeping the degree of insulation of the oil of oil-filled electric apparatus continuously under observation
IPC: H01F27/32
Filed: 1927-03-24
Abstract: 268,365. Kocsis, B. March 29, 1926, [Convention date]. Resistances, measuring; phase differences and power factors, measuring.-In order to keep under continuous observation the dielectric strength of the insulating oil of transformers, oil switches, &c., a condenser C1 is provided of which the dielectric is formed of the oil under test and the coatings are of such a size that a measurable current flows under normal circumstances and at such a distance apart that no discharge can occur between them. The ratio of the watt component of the current through the condenser C1 to the wattless charging current may be measured by means of a Sheering bridge, of which the condenser C1 forms one arm, a condenser C2 of known capacity forms a second arm, and a variable resistance R3 and fixed resistance R4 shunted by a variable condenser C4 form the other two arms. Current is supplied from a transformer T. The dielectric strength of the oil is determined from the power-factor of the condenser C1 so measured. In place of the Sheering bridge, the current passing through the condenser C1 may be measured by means of a milliammeter. On the dielectric strength of the oil diminishing, the charging current decreases only inappreciably, but the watt component increases considerably so that the deflection of the instrument is inversely proportioned to the resistance of the oil. The transformer winding or the container wall may form one plate of the condenser C1. A resistance or choking-coil may be provided in circuit with the condenser.

Filed: 1941-07-01
Abstract: 552,369. Steering ships; controlling aircraft. HORSTMANN, B. G. July 1, 1941, No. 8243. [Classes 4 and 114] [Also in Group XXIV] A mechanical relay, suitable for the control of aircraft, or the steering of ships, comprises a prime mover 1 e.g. an electric motor, which drives a shaft 2 having a spider 5 with planetary bevel pinions 6. The latter gear with two bevel sun wheels 7, 8, a wheel 7 being connected directly to a brake drum 12, and wheel 8 to a brake drum 14 through reversing gearing 16, 17. The drums 12, 13, which thus normally revolve at equal speeds in opposite directions, co-operate with brake bands 24, 25, actuated by a control member 21 pivoted to a casing 18. The latter is mounted freely in bearings 3, 4. A parallel shaft 26 has a spider 27 with planetary pinions 29, a member 37 connected to the part to be actuated, and a gear 36 meshed by an idler or not, to a gear 35 fixed on the casing 18. Suns 31, 33, free on shaft 26 carry gears 32, 34, meshing with gears 13, 15 fixed to the drums 12, 14. In operaton, movement . of the control member 21 causes one or other of the brakes 12, 14, to engage. This produces a differential movement of the gears 31, 33, 29, and moves the shaft 26 and member 37 through a distance corresponding to the distance moved by the control member 21, the power for moving the member 37 being derived from the motor 1. The gearing 35, 36, produces a follow-up action of the casing 18, and also permits the member 37 to be moved directly by the control 21 should the motor 1 cease to function.
