Patent GB-691437-A (GB)
Title: Improvements in display, advertising and like devices
IPC: G09F13/00
Filed: 1951-05-01
Abstract: 691,437. Thermal switches. MARCHMENT, W. T. April 22, 1952 [May 1, 1951], No. 10216/51. Class 38 (v) [Also in Groups XVIII and XL (a)] A sign (see Group XVIII) is intermittently actuated by a bimetallic strip 12, Fig. 1, which is heated by current from a transformer 11 and which engages a fork connected to an arm 16 and so rocks the arm between two stable positions. A mercury switch 13 which is connected in series with the current supply from the transformer is mounted on the arm 16 and so makes and breaks the circuit as the arm is rocked. In a modification, the bimetallic strip may form part of the sign and operates the mercury switch through a system of levers. In another construction, Fig. 7, a sign which includes two bimetallic strips 60, 61 is intermittently operated by a switch which comprises a shoe 67 and a member 66. When these are in contact with each other as shown, current is supplied to the bimetallic members 60, 61 and these tend to bend. This is resisted by the engagement of the shoe 67 with a non-metallic detent 69. When the pressure in the strips 60, 61 becomes great enough the shoe is snapped over the detent and breaks the circuit. The shoe then returns to its initial position this being aided by the back of the detent which is sloping. In a modification, movement of the shoe is resisted by a permanent magnet instead of a detent.

Title: Improvements in or relating to the measurement of interchangeability of combustible gases
IPC: G01N25/28
Filed: 1945-04-24
Abstract: 590,864. Gas burners. IGRANIC ELECTRIC CO., Ltd. April 24, 1945, No. 10279. Convention date, April 24, 1944. [Class 75 (i)] [Also in Group XX] The inner cone height of a burner of the Bunsen type is held substantially constant under all conditions by means of a temperature sensitive probe 48 in the cone. If the cone is too short the probe becomes hotter, increasing the pressure in the bellows and closing the air inlet valve 83. This decreases the combustion rate and the cone becomes longer again. The air valve adjustment necessary is indicated by a pointer 80 and may be recorded. This indication for different gases is a measure of their interchangeability. The gas pressure is held constant by a device 122a in series with the supply, and a screw device 97 provides a means of setting zero on the apparatus.

Title: Method of rendering animal fats
Inventor: DAYEN WILLIAM ROY
IPC: C11B1/12
Filed: 1956-04-04
Abstract: A method of continuously rendering fats comprises coarsely grinding the fatty tissue, for example to a particle size of 1/8 -\ba5/8 inch, and then heating the ground tissue, in a vessel open to the atmosphere, to a temperature not high enough to coagulate the protein in the tissue, but sufficient to melt the fat, suitably 100-120 DEG F.  Thereafter the fluid material is continuously pumped to a second heating zone where it is raised to a temperature high enough to coagulate the protein, suitably 160-170 DEG  F., and is then ground to a sub-cellular non-fibrous state with a particle size of 50-100 microns, and finally centrifuged while a temperature of 150-200 DEG F. is maintained so as to separate the fat from coagulated protein and water.

Title: Improvements relating to the manufacture of 5-hydroxy-methyl furfural or levulinic acid
IPC: C07D307/46
Filed: 1944-05-30
Abstract: Sucrose is treated with oxalic acid hydrate yielding hydroxymethyl furfural and bis(furfural-2-methyl)-ether which are extracted from the solution.  The residue is then treated with hydrobromic acid or hydrochloric acid (alone or in admixture with sodium bromide) producing formic acid and levulinic acid.  In an example, sucrose solution is treated under pressure with oxalic acid hydrate.  Humin is filtered off and the filtrate neutralized and stirred with basic lead acetate.  The precipitate is filtered off and the filtrate extracted with ethyl acetate thus removing hydroxymethyl furfural and bis-(furfural-2-methyl)-ether.  The aqueous layer from the extraction is evaporated to a syrup which is heated under pressure with hydrogen bromide.  After extraction with ether, formic acid is distilled off leaving levulinic acid. Specification 583,533 is referred to.

Filed: 1961-03-23
Abstract: 936,104. Valves. HYDRAULIC UNIT SPECIALTIES CO. March 23, 1961 [July 21, 1960; Dec. 12, 1960], No. 10734/61. Class 135. An hydraulic control comprises a housing 5, Fig. 1, having an inlet 6 communicating via overlapping passages 23-29 with outlet 9 and two parallel exhaust passages 36, 37, the passages being intersected by a bore 21 containing a relief valve, two bores 16 containing plungers 10, 11 controlling two hydraulic devices in parallel, i.e. either or both devices together may be operated, three bores 16 containing plungers 12, 13, 14 which operate three devices in series, i.e. the return flow from the first device is directed by the first valve 12 to the supply for the second valve 13 which may direct it to operate a second device, the return flow from which is also directed to the supply of the third valve 14 operating a third device, and a bore containing a conventional valve 15 supplying or exhausting motor ports 32, 33. The invention relates to two of the valves 12- 14, whereby power is saved by utilizing the pressure of return fluid. Pressure at 23, Figs. 2, 3, passes via check valve 44 to ports 40, 40<SP>1</SP> of valve 10 and via passage 46 and check valve 44, Figs. 2, 4, to ports 40, 40<SP>1</SP> of valve 11 so that the valves may be displaced from their neutral position to control their two devices in parallel. Valves 12-15 can only control their devices provided valves 10, 11 are in neutral position. Movement of valve 12 to the right cuts off passage 25 from 26 so that pressure passes check valve 44 and acts in ports 40, 40<SP>1</SP>. Pressure at 40 passes to motor port 33 via 50, 48, 51 and the return fluid from the actuated device at 32 acts via 53 on shoulder 60<SP>1</SP> of check valve 57, balanced by pressure acting via 60 on both its ends, so that valve 57 opens and return fluid pressure acts via 47, 54 in the supply passage 26 for the next series control valve 13. Movement leftwards of valve 12 allows supply pressure at 40 to pass via groove 55 to motor port 32 and return fluid pressure at 33 to pass to supply passage 26 via 51, 48, 50. Any of valves 12-14 may be constructed to have conventional control on movement in one direction and series control on opposite movement. Specification 915,114 is referred to.

Filed: 1951-05-08
Abstract: 697,537. Delivering paper sheets in counted batches. JAGENBERG-WERKE AKT.-GES. May 8, 1951 [May 23, 1950], No. 10782/51. Class 100(i) Marking tags 8, for dividing, e.g. into reams, a stack 6 of paper sheets delivered from a sheetcutting machine, are already folded down at their forward ends 23 into a U-like shape before introduction to the train of sheets. A particular sheet 4, or group of sheets, draws the tag 8 into the train of sheets cut from a web 1, or from a number of superposed webs, by a cross cutter 2. The strip for forming the tags is fed by rolls 10 from a reel 7 to an adjustable cutter 12 on a roll 11, the moment of cutting being determined by the raising of a counter roll 13 mounted on a lever 14 pivoted at 15. The forward end 23 of the tag 8, led by rolls 20, 21, is buckled in a channel 22 to be seized by roll 21 and a folding roll 24. Since its middle portion is recessed Fig. 4 (not shown), the roll 24 folds sharply only the longitudinal edges of the tag 8. The cut and folded tag is held in readiness in a feed channel 25 having a reciprocable mouthpiece 30. The core 35 of an electromagnet is attached by a flexible strap 33 to pins 31 on the mouthpiece 30, the pins moving in fixed guiding slots 32. When a set number of paper sheets 4 has been delivered from the web 1, or webs, a sheet counter 37, through a time-delay relay 38, energizes the electromagnet and moves the core 35 and mouthpiece 30 to expose the folded end 23 of the tag 8 for engagement with a sheet 4 or group of sheets to be marked. A spring 40 returns the mouthpiece to its original position for reloading. When a tag 8 is loaded ready in the mouthpiece 30, a motor 26 which drives the tag-making device is switched off by a lever 28 operated by a cam 29 on the same shaft 17 as a cam 18 for raising the lever 14. Just after the actuation of the electromagnet, however, a time-delay relay 39 closes contacts 27 for restarting the motor 26 to prepare a further marking tag 8.
