Patent GB-343922-A (GB)
Title: Improvements in or relating to the manufacture of goods of rubber or similar material
IPC: C08L7/00
Filed: 1929-11-25
Abstract: Materials suitable for making e.g. golf ball shells &c., and having physical properties resembling guttapercha are prepared by mixing aqueous dispersions of rubber and the like with aqueous dispersions of albumens other than haemoglobin, in such proportions that the albumen content lies between 25 and 75 per cent of the dry rubber-albumen content.  The most suitable albumen is commercial blood serum.  The mixture is then converted into easily dried crumb-like masses by, for instance, the addition of coagulants, for example aluminium sulphate or other salts of multi-valent metals. After drying, and if necessary slight mechanical disintegration the crumb-like masses are consolidated by heat and pressure.  The degree of toughness of the product may be varied by choice of the proportions of the main ingredients, and also by compounding and vulcanizing.  Example.-30 parts by weight of latex containing 18 parts of rubber, and 0,2 parts of ammonia are mixed with 38 parts of a mucilage containing 16 parts by weight of commercial blood serum albumen, and 0,2 parts of ammonia.  A 20 per cent solution of aluminium sulphate is stirred in till a crumb-like coagulum is obtained, which may be moulded at a pressure of 1000 lbs., at a temperature of 90-100 DEG  C. for 15 minutes to form for example hemispherical shells adapted to surround a golf ball centre previously wound with rubber threads. The shells are welded together in engraved moulds.  Specifications 219,635, 290,313, and 343,921, [all in Class 70, Indiarubber &c.], are referred to.

Title: Improvements in or relating to television receivers
Inventor: COPE JOHN EDWARD
IPC: H04N5/50
Filed: 1954-12-15
Abstract: 790,225. Automatic gain control. PYE, Ltd. Dec. 16, 1955 [Dec. 15, 1954], No. 36301/54. Class 40 (5). In a television receiver with automatic gain control of the " gated " type, the gain of the video channel is reduced until the H.T. efficiency diode comes into operation. In an arrangement as described in Specification 777,801, in which pulses produced by a sampling diode V1 are amplified by a valve V2 and rectified by a diode V3 and form, after smoothing, the A.G.C. potential, a resistor R3 and rectifier M1 are connected in series between the anode of the diode V3 and earth. The anode of rectifier M1 is connected by one resistor R1, to the line output transformer T1 and by another resistor R2 to a source of negative potential; until the efficiency diode V5 becomes operative, the rectifier M1 is biased so as to be non-conductive and a negative bias is applied to the A.G.C. line via resistor R3. Overload before the A.G.C. is operative is thereby prevented. The negative potential may be derived from the grid circuit of the line output valve V4 or alternatively (Fig. 1, not shown) from the sound A.G.C. circuit. Alternatively, or in addition, the screen grids of valves in the video channel may be fed via a potentiometer from the boost voltage.

Patent GB-867147-A (GB)
Title: Improvements in or relating to button feed controls for sewing machines
IPC: D05B3/22
Filed: 1958-11-12
Abstract: 867,147. Button testing. PFAFF A.G., G. M Nov. 12, 1958 [Nov. 16, 1957], No. 36442/58. Class 40(3) [Also in Group VII] In a mechanism for feeding buttons of the type having a different degree of light reflectivity in opposite faces, e.g. mother of pearl buttons, to a sewing machine, the buttons are passed through a photo-electric checking device which determines whether the buttons are right side uppermost and have the requisite number of holes. When a faulty or incorrectly positioned button is detected a reject mechanism is actuated which moves the button from the feed path into a second path, which incorporates a twist of 180 degrees, along which the button is moved before reinsertion in the feed path. Buttons 3 are fed in the direction of the arrow along a feed path 1, 2 to the button clamp of a sewing machine (not shown) and are tested at the button position next to the lowest by a photo-electric test device. In the device, Fig. 1, light from a source 5 is reflected by the button surface and is reorientated by a prism 7 and passed via the holes in the button to a photo-cell 9. The cell is connected in the grid circuit (Fig. 2, not shown) of one of a pair of triodes connected in a bridge circuit across which a polarized relay is connected. An incorrectly positioned button or one without the requisite number of holes reduces the light incident on the cell and the bridge unbalances to operate the relay in a direction which energizes the solenoid 91 and actuates the slide 102 which moves the button into the reversing path 101. If no button is present at the photo-electric check point, increased light passes to the cell via the mirror 110 and the bridge unbalances and operates the relay in the opposite direction which prevents the operation of the sewing machine start mechanism.

Abstract: 909,412. Semi-conductor gas detector diodes. MINE SAFETY APPLIANCES CO. Nov. 12, 1958, No. 36447/58. Class 40 (1). [Also in Group XXXVI] A semi-conductor gas detector diode, particularly for use in the ambient detector of Specification 909,413 in which electrically active particles in an ambient, e.g. ions electrons polar molecules, &c., affect the electrical characteristics, particularly back resistance, of a semi-conductor junction, comprises a semi-conductor PN junction so adapted that a large area of the junction is exposed to the ambient under test, e.g. in Fig. 1, the ambient gas or vapour is led through a plurality of parallel holes bored through the junction in the plane of the junction, the gas entering by conduits 23, 24, and leaving by 26, 27, 24 and 26, being sealed to the semi-conductor material by gas-tight seals and the whole device being covered with an insulating layer of plastic or varnish after electrical connection 28 and 29 have been made. Alternatively, the holes may be bored perpendicular to the plane of the junction as in Fig. 3, not shown, in order to give a higher power output due to the larger function area. Alternative embodiment with a faster response time may be constructed by utilizing a base of insulating or low conductivity material, e.g. graphite, with a layer of N-type germanium on one face. A portion of the germanium is reduced to a thickness of 100 microns by either mechanical or electrochemical means and then a portion of the material is converted to P-type by either irradiation or doping with acceptor material preferably controlling the conversion to produce a zig-zag junction as indicated in Fig. 12, not shown. The base has a hole running through it from end to end containing a tubular member having either a porous portion or a slot adjacent to the semi-conductor junction to allow the ambient access direct to the underside of the junction. The outer surface of the device being encased in insulating material preferably plastic. The interior of the tubular member may be packed with a suitable material to eliminate unwanted components of the ambient e.g. calcium chloride to eliminate water vapour.

Title: Process for the manufacture of formaldehyde and methyl alcohol
IPC: C07C45/49
Filed: 1920-12-31
Abstract: These are produced by momentarily heating methane with carbon dioxide.  The process may be carried out in the so-called isoprene lamp or by passing the gas mixture through a constricted tube which is heated at the constriction.  Slow passage of the gas, and the presence of much hydrogen, favour the formation of methyl alcohol, and rapid passage the formation of formaldehyde.  The tube may be made of copper, silver, nickel, or alloys of the metals with each other, or alloys with aluminium, tin, or zinc; or the tube may be of steel or iron, and contain turnings or wire of copper, silver, aluminium, nickel or their alloys.  The reacting gases may first be passed through methyl or ethyl alcohol, in which case small quantities of air may be introduced into the gases; or the mixture may be diluted with an inert gas, such as nitrogen, or a neutral hydrocarbon.  Gases containing methane, such as natural gas, may be employed; and the pressure may be reduced during the process. According to examples:-(1) formaldehyde is condensed from the products obtained by passing a mixture of two volumes of carbon dioxide with one volume of methane through a heated constricted tube; (2) the mixture of carbon dioxide and methane is passed into ethyl alcohol and then passed through an isoprene lamp provided with a silundum rod, or a wire of noble metal, electrically heated.
