Title: Improvements in or relating to guards for machinery
IPC: F16P3/04
Filed: 1932-09-06
Abstract: 392,798. Machinery guards. F.ORMAN & SONS, Ltd., T. and COOKE, G. U., Hucknall Road, Nottingham. Sept. 6, 1932, No. 24817. [Class 80 (iv).] Both hands of the operator are engaged in starting a machine such as cutting and stamping machines ; one hand pulls forward a guard frame 15 and the other operates a bell-crank handle 10, 8 and latch 11 to release the usual transverse clutch lever 7. When the machine has been started the guard is maintained automatically in the fully guarding position during the working stroke. Fig. 3 shows a guillotine of the hydraulic type. The frame 15 is pivoted on a shaft 18 and is connected by links 20, 21 to a vertical slidable rod 22. A longitudinal lever 26 is connected to the rod 22 by a link 24 and carries at the other end a roller bearing on a cam on the main drive shaft. When the guard is swung forwardly the rod 22 descends and brings a screw 33 to bear on the tail of a pivoted latch 34 to release the end 7a of the lever 7. The other latch 11 is then released by means of the handle 10, whereupon the lever 7 moves under spring influence to engage a clutch 6 and start the machine. The rotation of the cam tilts the lever 26 to bring the pivot pin 25 to the lower end of a slot in the link 24 and maintain the bar 22 depressed and the guard 15 raised as shown. After the knife 1 has done its work the cam allows the rod and guard to return to normal position. The lever 7 is then caused to throw out the clutch and re-engage the latch 34 by the usual knocking-off lever. In modified mechanism for use with the weight type of guillotine machine a lever 42, Fig. 7, with a fixed pivot 43 takes the place of the lever 26. It carries a roller 44 in contact with a cam 45 on a fixed pivot 46. A slotted rod 50 connects a crank 51 on the drive shaft 5 with a rod 47 screened to the cam 45. When the shaft 5 begins to rotate the cam is rotated by the bars 50, 47 to present the circular part to the roller so that the bars 24, 22 are pulled upon to maintain the guard in its forward or guarding position. When the pressing and cutting action is finished a projection 56 on the crank 51 meets a trip lever 57 which then slides a spring-pressed bar 58 to move the lever 7 and knock the clutch out of engagement. Lever 7 is then again engaged by the catch 34.

IPC: F16K17/18
Filed: 1962-06-28
Abstract: 940,469. Fluid-pressure servomotor control systems. GES FUR LINDE'S EISMASCHINEN A. G. June 28, 1962 [June 30, 1961], No. 24820/62. Heading G3P. A relief valve for relieving pressure between two flow passages, either of which may be the high pressure passage, such as in a hydraulic transmission, comprises a spool valve member 14 loaded to a closed position by spring 12 and movable to connect chambers 1 and 2 having passages 22 and 23 connected to the flow passages. Passages 3, 4 in the spool lead from the chambers 1, 2, in the closed position of the valve, to ball relief valves 5 loaded by a common spring 7. The relief sides of the valves lead to a chamber formed by one end of the spool and a plug 24 such that when the pressure in the high pressure line exceeds a predetermined value, the fluid pressure opens the respective relief valve 5 and acts on the spool to connect chambers 1 and 2. The chambers at either end of the spool may lead through restrictors 10, 11 to a chamber 18 connected to the low pressure line or exhaust. The spool may be moved manually by rotation of a handle 25 which rotates a plunger 28 carrying a pin 27 engaging a helical groove 29 whereby the plunger waves axially to open the spool valve.

Title: Animal feeding-stuffs manufacturing process
Inventor: COLLIER JOHN BRIAN
IPC: A23K10/33
Filed: 1961-07-10
Abstract: In a process for the production of an animal feeding stuff comprising cereal and molasses a mixture of whole cereal grain (e.g. barley) and molasses are passed through a compaction zone which breaks the pericarp of the cereal grain, the quantity of molasses being such that the product is non sticky and dust free. Up to 5% of other additives (magnesite, urea, minerals) may be present in the feed and may be dispersed in the molasses before mixing with the cereal or added to the molasses-cereal mix prior to compaction.  In the absence of magnesite the amount of molasses present is 2 1/2 % to 10%.  If magnesite is present 2 1/2 % to 7% molasses is used.

Abstract: 232,000. Marks, E. C. R., (Phillips, B.). Oct. 10, 1923. Machine guns.-Relates to double-barrelled guns adapted to fire the barrels alternately, and consists of providing the barrels with interconnected gasoperated breech mechanisms so arranged that the gas piston of the fired barrels opens its breech and simultaneously closes the breech of the other barrel and fires the same; this arrangement avoids the use of return springs for closing the breeches. As shown in Figs. 2 and 3, the barrels 1 are detachably secured within a housing 3, which is in turn secured to a breech casing 4. The gas cylinders 12 with their piston rods 13 are situated beneath the barrels, and the piston rods 13 have rack teeth 14 in mesh with a spur wheel 45 which causes one rod to be driven forward by the backward movement of the other. A handle w is fitted to one of the piston rods. The breech-bolts 16, 17 have locking lugs 21 and cam slots 22 engaged by upstanding posts on the piston rods. Usual extractors are also provided. The breech portions of the barrels are constituted by tubular members 35, Fig. 7, screwed to the barrels, and recessed at 39 to receive the breech .casing 4. The barrel housing 3 has a rearwardly extending tougue j which slides beneath a web 9, Fig. 10, in the breech casing 4 and is secured thereto by means of a catch o, which has a lip p on a projection n adapted to engage in slots in the web and tongue, and a depending post q adapted to engage in a hole in the web. A coverplate t is secured to the breech casing by interengaging lugs and a spring catch v, and this cover-plate when in place locks the member o against displacement.

Title: Flowmeters

IPC: G01F1/68
Filed: 1967-06-01
Abstract: 1,127,568. Flowmeters. FORD MOTOR CO. Ltd. June 1, 1967, No.25333/67. Heading G1N. The rate of flow of fluid through a conduit is determined by measuring the change in temperature as it flows over the cold junction of a Peltier thermo-electric device. As shown (Fig. 1) a conduit 1 carrying a fluid is part surrounded by a group of sintered bismuth telluride thermoelectric elements 2 connected electrically in series and thermally in parallel, energized by a controller 4, whereby the upstream end 2a of the element assembly is a cold junction, and end 2b a hot junction. The temperatures before, at and after the junction are measured electrically at 5, 7 and 6 respectively. Thermometer 7 controls unit 4 to maintain a constant temperature at the cold junction 2a. The difference between the upstream and downstream temperatures is determined at 8 and modified at 9 in accordance with the upstream and cold junction temperatures to give a signal at 10 indicative of the fluid flow. In a modification the controller 4 supplies a constant current to the Peltier unit, instead of maintaining the cold junction at a constant temperature. In another embodiment (Fig. 2), the temperature difference across the Peltier unit 2 is maintained at a constant value by controller 12 and amplifier 11 feeding the unit 2. Automatic compensation for variations in the initial fluid temperature is produced by a temperature-sensitive resistor 15 in series with the output from amplifier 11.
