Title: Improvements in and relating to depilatories and methods of compounding the same
Filed: 1932-09-22
Abstract: A depilatory comprises an alkaline solution of a stannite, an amphoteric compound serving as a buffer to combine with the excess of alkali present, and an alkali salt of a hydroxy polybasic organic acid, e.g. tartaric acid or citric acid, serving as a stabiliser to prevent decomposition of the stannite.  The stannite is preferably one more soluble than calcium stannite and may, for example, be sodium stannite or barium stannite or mixtures thereof.  The buffer compound may be aluminium hydroxide or zinc hydroxide or stannous hydroxide.  The stabiliser may be Rochelle salt.  The depilatory may be obtained by treating a solution of stannous chloride with a solution of sodium carbonate, separating and washing the precipitate, mixing the precipitate with Rochelle salt dissolved in a small amount of water and adding caustic soda solution to dissolve partly the stannous hydroxide.

Patent GB-1462886-A (GB)
Title: Pipe couplings
IPC: F16L37/084
Filed: 1974-06-13
Abstract: 1462886 Pipe couplings I STRAUB 13 June 1974 [15 June 1973] 26340/74 Heading F2G A sealing gasket 21 incorporated in a pipe coupling 10 (Fig. 1) is of generally C-shaped cross-section with end edges constructed as sealing lips 23, 24 intended to bear against the respective pipe ends, the gasket 21 having a web 22, each sealing lip 23, 24 having a lip root and being supported at the web 22 by a substantially ring-shaped bead 31, 32 spaced axially from the associated lip root, the gasket 21 being provided with spaces 27, 27<SP>1</SP>, 27<SP>11</SP> to each side of the beads 31, 32, and the spaces being connected with one another by through passages 33 (Fig. 6). The gasket 21 is supported by a tubular housing 11 slit lengthwise at 12 and clamped by bolts 17 which interconnect a pair of rods 15, 16 held in the edges of clamping brackets 13, 14, the latter being welded to the housing 11. Each sealing lip 23, 24 is tapered towards a free end of minimum thickness remote from its lip root, the associated bead 31, 32 bearing only against the free end of a sealing lip, at least during such time as the housing is not yet clamped. To resist axial forces displacing the pipe ends away from one another, the housing has inwardly bent ends 19, 20 against which rest anchoring rings 29, 30 lamellated as indicated in Fig. 1 and in the shape of truncated cones so that the lamellae overlap at the inner diameter. The rings 29, 30 are supported at their outer diameter by resilient expandible rings 34 which each consist of a wire ring 35 around which is wound a helical spring 36 having tightly contacting coils. In operation, the pipe connection is sealed in the absence of internal pressure by virtue of the ring beads 31, 32 which press the sealing lips 23, 24 against the outer diameter of the pipes. As internal pressure in the pipe increases, the lips 23, 24 become deformed giving an increased sealing action and the lamellae of the anchoring rings 29, 30 are forced to claw into the outer diameter of the pipe to prevent axial movement. In an alternative embodiment (Fig. 9) suitable for use, e.g. where the gasket material has inadequate elasticity, a separate ring 38 of appropriate elastic material is provided having a bead 31 and a bulbous portion 41, and so shaped that it fits exactly into a complementary portion of a gasket 21. A compartment 27<SP>1</SP> is thus formed and is connected with compartment 27 by bores 33. The two components of this embodiment may conveniently be produced in vulcanization moulds for use especially with smaller diameter pipes, whilst the one-piece gasket may be formed from an extruded band and is more suitable for use in connecting larger diameter pipes.

Title: Improvements in or relating to sealed containers having removable and replaceable closure caps
IPC: B65D41/04
Filed: 1938-09-09
Abstract: 518,943. Closures for containers. WALLIS TIN STAMPING CO., Ltd., and WILLIAMS, A, J. Sept. 9, 1938, No. 26403. [Class 125 (iii)] The mouth of a container is sealed by a cap 14 which is retained in position by a flanged band 20 while a bayonet type connection is provided between the flange 16 of the cap and the neck of the container. The container, which may be a glass bottle, has a continuous circumferential ridge 11 and an interrupted rim 12 on its neck 10; the underside of each portion of the rim 12 is a cam face 13. The cap is formed from a blank stamped from a sheet of metal, and has a number of extensions, which after the flange 16 has been formed, are rolled inwardly to form the projections 17. When the cap is put on the container, these projections pass through the gaps in the rim 12 and the cap is held by the band 20 the edge 22 of which is curled beneath the continuous rim 11. The band is secured by the clasp 23. When it is desired to re-seal the container after use, the projections 17 are passed through the gaps again and the cap is twisted to bring them into engagement with the cam faces 13. A sealing washer 19 may be placed between the container' rim and the cap, and a disc label may be placed between the flange 21 of the band 20 and the top of the cap.

Title: Write control circuit
IPC: G11C11/411
Filed: 1972-06-07
Abstract: 1371686 Bi-stable transistor circuits INTERNATIONAL BUSINESS MACHINES CORP 7 June 1972 [16 July 1971] 26506/72 Heading H3T [Also in Division G4] An array of cross-coupled transistor storage cells has means (e.g. an exclusive OR gate) to prevent the application of write signals to the cells if the state of the cell corresponds with the data to be written in. In Fig. 2 the cell comprises cross-coupled double emitter transistors Q3, Q4 together with output transistors Q2, Q5, Q6, Q7 and Q8. Current flow to the outer emitters is normally prevented by transistors Q15 and Q16 which are conducting. To change the state of the cell a cell select pulse is applied at 24 to cut off Q15 and Q16 and an "up" or "down" data signal is applied to terminal 13. Accordingly one or other of transistors Q11, Q12 conducts, holding the outer emitter of the conducting one of transistors Q3, Q4 non-conducting and allowing conduction to the outer emitter of the other. The circuit is thus caused to change state. As soon as the change is effected the fall in potential of the collector of the conducting transistor acts via Q5, Q7 and Q18 or Q2, Q6 and Q12 to raise the potential of the conducting outer emitter and thus prevents the remaining part of the write pulse from driving the transistor to saturation. If the state of the cell had corresponded to the new data the write pulse would likewise have been inhibited and the dissipation of power thus reduced.

Title: Improvements in or relating to electromagnetically-operated brakes
Inventor: REECE FRANKLIN AUGUSTUS
IPC: D05B69/22
Filed: 1954-09-14
Abstract: 752,175. Sewing-machines. REECE CORPORATION. Sept. 14, 1954, No. 26660/54. Class 112. [Also in Group XXXV] A drive shaft 20 of a sewing-machine is adapted to be coupled to an electric motordriven pulley 25 through a clutch comprising a driving element 26, which is fixed to the pulley, and a driven element 35, which is keyed to the shaft. Finely-divided magnetic material 50 is disposed in the space between the driving and driven elements of the clutch so that the parts run freely and the drive shaft remains stationary when a magnetic coil 55 is de-energized. Energization of the coil 55 causes the magnetic powder to form a bond between the two clutch members. Also keyed to the shaft 20 is a stop element 60, the surface of which is in close proximity with a stationary shell 62, a quantity of magnetic powder 50<1> being disposed between the members 60, 62. Energization of a coil 75 magnetizes the material 50<1> which forms a bond between the stop element and the shell, so that a comparatively small current in the coil 75 causes braking of the drive shaft, whilst a large current stops and locks the shaft against rotation. The members 26, 62 are provided with non-ferrous rings 27, 63. A number of cams are carried on the shaft 20 for actuating timing switches 85a, 85b and 86a, 86b. When a starting switch 115 is open, current passes from transformer 112 through rectifier 120 to energize brake coil 75 at comparatively high voltage so that the drive shaft is held stationary. Closure of switch 115 energizes relay 140 to complete a low-voltage circuit from rectifier 161 to the coil of relay 150. The relay 130 is thereby actuated to break the circuit of brake coil 75, and the starting switch may now be released to de-energize relay 140, the relays 130, 150 being provided with holding circuits. The clutch coil 55 is now energized to start the sewing operation which continues until a stop switch 170 is actuated either manually or by the movement of part of the machine. During the next rotation of the drive shaft, the switches 85a, 85b are successively opened, thereby deenergizing the relay 150 and the clutch coil 55. The switches 85a, 85b then re-close to complete a low-voltage circuit to the coil 75 to decelerate the machine. The switches 86a, 86b are then held open to break the holding circuit of the relay 130 and to establish a higher voltage circuit to the coil 75 for bringing the drive shaft to an immediate stop.

Title: Polymerisation of episulphides
IPC: C08G75/00
Filed: 1964-06-30
Abstract: Episulphides are polymerized using compounds of zinc, cadmium and mercury as catalysts and certain nitrogen containing compounds as cocatalysts.  The catalysts comprise the alkyls, sulphides, halides, and oxides of zinc, cadmium and mercury and the carbonates of zinc and cadmium.  The cocatalysts are ammonia, inorganic ammonium compounds, e.g. ammonium hydroxide, sulphide and carbonate, organic amines, e.g. primary aliphatic amines, diamines, triamines, cyclic imines, amino alcohols, and amino acids, hydrazine and its derivatives, e.g. phenyl hydrazine, hydrazine hydrochloride and hydrate.  The molar ratio of cocatalyst to catalyst is preferably from 1 : 1 to 100: 1. Suitable episulphides include alkylene, alicyclic, unsaturated, and aromatic episulphides, episulphides containing more than one episulphide group, e.g. 1,5-hexadiene diepisulphide, and halogen-substituted episulphides. Solvents may be employed, e.g. hydrocarbons, chlorobenzene, ethers, aliphatic alcohols, dimethylformamide, water, chloroform, and amylacetate. The polymers may be cured using oxides or peroxides of Groups IB to IVB and VA metals, an inorganic oxidizing agent, e.g. Zn, Pb, K or NH4 chromate, MnO2, MgO or arsenious oxide, methylene bis-(4-phenyisocyanate) or a quinonoid compound as curing agent. Reinforcing fillers such as carbon black, silica, and clay, antioxidants, and plasticizers can be added.  In the examples, a wide range of monomers, cocatalysts, solvents &c. are specified, the main catalyst component in each case being ZnCO3, ZnO or CdCO3.  Reference has been directed by the Comptroller to Specifications 1,042,149, 1,042,253, 1,059,490, 1,059,491 and 1,073,083.

Abstract: 1,146,004. Making stereoscopic pictures. EASTMAN KODAK CO. June 16, 1966 [June 21, 1965], No.26919/66. Headings G2A and G2J. A method of making a positive lineiform image having exactly the same pitch as a given lenticular screen through which the image is to be viewed to obtain a stereoscopic effect, comprises taking a test screen having a pitch different from that of the given screen, ascertaining the spacing of the moirÚ lines produced when the two screens are superimposed in alignment, and making the required image such that, when aligned with the test screen, it produces moirÚ lines having the same spacing. A sheet of sensitive photographic material may be exposed to the adjusted image to make a printing plate thereof. The image is preferably adjusted by being projected on to a screen at the plane of the test screen and the size thereof altered by varying the magnification of the projection system. The test screen may be made from a transparent material or on a reflecting support. To avoid confusion in obtaining the required pitch, the lineiform image is preferably compared with two test screens each having different pitches different from the pitch of the given screen, the image size being adjusted until it produces, with each test screen, the moirÚ spacing that the given screen produces therewith. A composite lineiform image, i.e. an image containing two or more lineiform images separately produced, may be prepared, the above method being used to ensure that images each have the same pitch.
