Title: Improvements in shipping case unloading apparatus
IPC: B65B21/18
Filed: 1950-07-24
Abstract: 681,493. Unpacking-machines. HARTFORDEMPIRE CO. July 24, 1950 [Aug. 17, 1949], No. 18432/50. Class 94(i) [Also in Group XXX] In a machine for removing articles such as glass jars or bottles from packing cases, the case is positioned with its flaps opened on a verticallymovable table 5 which is then elevated by an aircylinder 17 controlled by a pedal 6 to position the jars &c. for engagement by a corresponding number of pairs of grippers 61, 62 mounted on a stationary head 2. The upward movement of the table is arranged to trip a clutch and cause one revolution of a main cam shaft 32, and a cam 68 thereon operates through linkage to expand the grippers into engagement with the interiors of the jars. A cam 75 then operates to actuate a valve 15 which releases the pressure in the cylinder 17. whereby the table returns to its lower position leaving the charge of jars suspended by the grippers. At the same time, a cam 104 operates through linkage and rack and pinion mechanism to cause a plate 85 carrying rods 84 to descend and strip the case from the jars. A carriage 10, which is reciprocable horizontally by a further cam 112 operating through linkage and rack and pinion mechanism, is then moved to the left into a charge-receiving position and a member 136 thereon moves the empty case from the table 5 on to a delivery conveyer 7. When the grippers are released, the jars fall on to parallel rails 120 of yielding material which are mounted for vertical movement on the carriage 10 and are raised when the carriage moves to the left so as to reduce the distance through which the jars fall, the rails being lowered as the carriage moves back to the right so that they pass under the bottom 11 of a trough 12 on to which the charge of jars is delivered. In the next cycle of operations, the charge of jars on the trough 12 is moved by the succeeding charge on to a delivery conveyer 9. In a modification, Figs. 19-25 (not shown), arranged to remove bottles from a case and deliver them in parallel rows on to the conveyer 9, the grippers are arranged to engage the exterior surfaces of the bottle necks.

Title: Improvements in or relating to sorting machines for statistical record cards
Inventor: ROSE BERTRAM LESLIE
IPC: G06K13/04
Filed: 1956-06-14
Abstract: 805,071. Sorting record cards. POWERS-SAMAS ACCOUNTING MACHINES Ltd. May 6, 1957 [June 14, 1956], No. 18485/56. Class 106 (1). In a record card sorting machine the cards after sensing are conveyed by rollers 4, 5 past a series of pockets each having a normally closed flap 7, an endless chain 19 or conveyer moving with the cards having settable levers 18 which when set open the appropriate flap to allow the card to enter the pocket. The flap spindles 8 are extended and each carries a lever 12 fixed to it, connected by a link 17 to a parallel lever 13 freely movable on the next spindle. A spring 14 normally holds the flap closed, a lever 15 then bearing against pin 16. A flap is opened when the corresponding operating link 17 is pressed downwardly. This is effected by one of a number of levers 18 mounted in a row on transverse rods 20 carried along by chains 19 at the same speed as the cards, one rod corresponding to each card. The links 17 are staggered across the width of the chain and a lever 18 is provided for each link position so that a displaced lever 18 will engage only the corresponding link. The levers are set by being displaced downwardly and are held in the normal or set positions by a spring-loaded catch pin 21, Fig. 3, which engages in one of two notches 23, 24 in the periphery, as shown in Fig. 3. According to the data sensed one of a bank of magnets 34 is energized to hold the corresponding one of a number of bell-crank levers 28 in a clockwise position to which they are all displaced cyclically by cam 33. As the row of levers 18 corresponding to the card last sensed passes under the levers 28 the appropriate one is displaced into the operative position. This lever opens the corresponding flap just before the card reaches it and deflects the card into the pocket. The levers 18 are reset by cam segments 27, one of which is provided for each lever and which when displaced in a clockwise direction by ramp 36, Fig. 3, withdraws the corresponding catch pin 21. The displaced lever is then returned to the inoperative position by a ramp 38 and a ramp 37 returns the cam segment to the inoperative position.

Title: Improvements in or relating to chain stitch sewing machines
IPC: D05B1/20
Filed: 1960-05-27
Abstract: 906,277. Sewing-machines. FENDT, H., and FENDT, X., [trading as FENDT & CO., X.]. May 27, 1960 [May 27, 1959], No. 18900/60. Class 112. In a chain-stitch sewing-machine, verticallyhanging work is fed past the needle by two cooperating endless bands mounted for movement in a horizontal plane. The machine, which is designed to replace the normal cup-feed machine, is intended for sewing together the selvedge edges of pieces of material. Toothed rollers 3a, 4a, 5a are journalled in a triangle on a bracket 1 rigid with the machine frame 2, and carry a continuous belt 7 toothed on both sides. The apex roller 4a is positively driven. Toothed rollers 3b, 4b, 5b are journalled on a plate 11 and carry a toothed belt 8. The runs of the belts at the bases of the triangles co-operate to feed the work therebetween. Plate 11 is pivoted on the axis of the apex roller 4b to a bracket 13 which is slidably mounted in frame 2 and is biased by spring 15 to urge plate 11 towards bracket 1. A spring 14, interposed between bracket 13 and plate 11, tends to bias the latter counterclockwise, whereby, when bracket 13 is actuated to move plate 11 away from bracket 1, the rollers 5a, 5b remain closed together, while a gap opens between the rollers 3a, 3b to facilitate the introduction of the work therebetween. The work passes between plates 9 and 16 rigid with bracket 1 and plate 11, and formed with needle-passing passages 10 and 17, respectively. The needle 20 does not fully withdraw from passage 10. The thread chain formed between successive pieces of work is gripped between, and drawn through the machine, by co-operating serrated flanges on the rollers 5a, 5b.
Patent GB-682064-A (GB)
Title: Improvements in or relating to the preservation of perishable liquids
IPC: A23C3/07
Filed: 1948-07-14
Abstract: Liquid products or liquefiable products liable to damage by enzymes or micro-organisms and containing proteins or vitamins which deteriorate under conventional sterilizing heat treatment, e.g. blood plasma, blood serum, milk, whole egg, egg yolk, butter, are sterilized by quickly heating by high-frequency electrical energy to a temperature above the boiling point of the product at atmospheric pressure, and, immediately after this temperature is reached, are quickly cooled by sudden release of the pressure and vaporization from the product.  Milk, preheated to 55 DEG  C., is heated by the method to 120 DEG  C. in less than 2 seconds, and cooled practically instantaneously to below 45 DEG  C.; the cooling may be sufficient to freeze the product.  The release of pressure and vaporization may be effected by atomizing the heated product into a current of chemically inert gas, e.g. air or carbon dioxide when milk is being treated, so as to obtain a dry product, the apparatus for such a procedure comprising a supply container for the product, a tube lead therefrom to an atomizer, and devices for developing high-frequency electrical energy in the tube lead immediately before the atomizer.  According to an example, butter in a closed container is heated by high-frequency electrical energy to such a temperature that the pressure rises to 2 atmospheres, heating from 80 DEG  C. taking not more than 0.1 sec., and after heating the pressure is released, whereupon the butter cools by evaporation of moisture therefrom. Specification 619,495 is ferred to.

Title: Improvements in and relating to means for regulating the supply of air to the furnaces of steam boilers
IPC: F23N3/02
Filed: 1920-07-06
Abstract: 148,755. Schwarz, J. July 30, 1919, [Convention date]. Fluid-actuated valves.-In a valve or regulator for controlling the air-supply to a boiler furnace in accordance with the boiler pressure, the pressure of the boiler 12 acts upon the liquid in a stand-pipe 11, the liquid rising until it enters an extension 9 arranged at a height corresponding to the pressure to be maintained. A subsequent small rise in pressure results in a comparatively large volume of liquid entering the extension 9 and displacing a corresponding volume of air or other gas which acts on the regulator and causes a rapid closing of the air-supply to the furnace. In the apparatus shown, the chamber or extension 9 is mounted on a tube 10 slid able in the stand pipe 11 so that it may be adjusted to a height corresponding to the pressure to be maintained. The air-regulator comprises a vessel 1 containing a bell 2 mounted over the end of the air-pipe 3 of the furnace 4, the air opening being controlled by the level of liquid contained in the vessel 1, which more or less closes the mouth of the ball 2. A pipe 6 connects the vessel 1 to a chamber containing liquid, the space above the liquid in this chamber being connected by a pipe 8, preferably of small section, to the chamber 9. The gas expelled from the chamber 9 forces liquid from the chamber 7 into the vessel and so tends to close the air-supply.
