Patent GB-636322-A (GB)
Title: Polymerization of alpha-substituted haloacrylic compounds
IPC: C08F20/62
Filed: 1946-05-23
Abstract: Colourless transparent polymers are produced by polymerization of monomeric a -halogen acrylic acid compounds in the presence of an ester of an organic hydroxy acid, soluble in both the monomer and corresponding polymer, in amount from 0.1 per cent of the monomer to the limit of mixibility in the polymer and which reacts with any oxalyl halide compounds present or which may be formed during or after polymerization to yield colourless products.  In general the ester does not exceed 4 per cent of the monomer. Specified hydroxy esters, which may be polymerizable, are methyl, ethyl, b -hydroxy ethyl, propyl, phenyl, cyclohexyl, vinyl, isopropenyl, allyl, methallyl, crotyl and cinnamyl glycollates and hydracrylates.  Listed a -halogen acrylic acid compounds include methyl, ethyl, propyl, isopropyl, butyl, tert.-butyl, phenyl, benzyl, cyclohexyl, allyl and methallyl a -chlor- and a -brom-acrylates, a -chlor- and a -brom-acrylamides and the N-methyl derivatives thereof, and a -chlor-acrylonitrile. The process may be carried out by mass, solvent, granular or emulsion polymerization methods and may be promoted by use of light or other catalysts, e.g. benzoyl, succinyl peroxides, peracetic acid.  Generally, polymerization is effected by heating, e.g. at 20-120 DEG  C., preferably between 35 DEG  and 65 DEG  C., and the polymer subsequently hardened by heating between 100 DEG  and 120 DEG  C. for from 8-24 hours.  The products may be moulded, e.g. to form optical media, which are scratch-resistant, transparent and non-brittle, which may be shaped by machining and polishing. Specifications 518,970, 527,494, 636,319, and U.S.A. Specification 2,247,790 are referred to.

Title: Peak detector circuits
IPC: G01R19/00
Filed: 1975-04-16
Abstract: 1500997 Measuring peak voltage SONY CORP 16 April 1975 [25 April 1974] 15653/75 Heading G1U [ Also in Division H3] The output signal from a peak detector is enhanced during periods when the input signal is increasing by varying the feedback of an amplifier connected to the peak detecting circuit. This enables the output to represent the input signal more closely during such periods by overcoming any inertia in the detector load e.g. a peak level meter, or a D.C. motor. In the Fig. 2 embodiment, A 1  operates with a logarithmic response and A 2  as a full-wave rectifier and linear amplifier with diodes D3, D4. The amplifier A 2  output is peak detected by diode D 5  and capacitor C 1 . Changes in the level detected by C  1  cause current flow through C 2 , and an increasing level increases the current flow in a transistor Q 1  which thus reduces the feedback current to the amplifier input terminal in feedback circuit NF. This increases the amplifier A 3  gain, thereby enhancing the output signal, giving an extra 'kick' to the meter M. In alternative embodiments, Figs. 3, 4 (not shown) a transistor (Q 2 ) base-emitter junction forms the detecting circuit with a capacitor, and any increases in the collector current are sensed to vary the negative feedback in a following amplifier.

Title: Automatic Sorting System
IPC: B07C3/02
Filed: 1967-04-06
Abstract: 1,157,712. Sorting postal mail; packaging mail. INTERNATIONAL STANDARD ELECTRIC CORP. 6 April, 1967 [11 April, 1966], No. 15792/67. Headings B8A and B8C. Postal letters to be sorted are inserted in magazines 13, the addresses being encoded magnetically by a keyboard operator on coding bars 64 by low-level (40 gauss) magnetization. At a station 4, the magazines are inverted by a rotary member 50 (Fig. 4, not shown). This is to bring the coding bars to a suitable position to be processed by " read " and " write " heads 15, 16 of a code converter 5. This is coupled to a computer 6 which converts the original code to one of simplified form and which is written on the coding bar 64 with high-level (400 gauss) magnetization. The magazines then pass to an output station at which the coding bars are subject to a sensor 17. Those carrying certain predetermined codes are ejected by an actuator 18 into pockets 38 of heat-shrinkable material on a web 32 (Fig. 7). This operation is facilitated by air flow through ports 33 and 42. Air from a source 31 is heated at 36 and vented at 35 on to the pockets to cause them to shrink tightly over the letters carried therein. Magazines 13 containing letters still unsorted are carried via another inverter 8 (similar to the inverter 4) off the main conveyer circuit on to a branch loop (dotted lines, Fig. 1) which leads to a storage arrangement 9 (Fig. 6). This comprises a plurality of storage rows 90 for the magazine 13 served by a sleevable input conveyer arm 92 and a similar output arm (not shown). From the storage arrangement 9, magazines pass back into the main conveyer circuit, through the inverter 4, and are subject to another sortation pass as before. When the magazine is completely empty, it is routed along a path 11 instead of passing through the storage 9. Circuit details of the converter 5, sensor 17 and actuator 18, are shown in block form (Figs. 9 and 10, not shown). The junctions between the branch conveyer loop and the main conveyer circuit (Figs. 5A, 5B, not shown) comprise hinged endless belt sections (55) which are lowered so as to deposit the container on the downstream section of the conveyer junction. The hinged sections are operated automatically in response to the activation of position sensors (57)-(60).

Abstract: 968,155. Laminates and laminating. UNITED STATES RUBBER CO. April 26, 1962 [June 1, 1961], No. 15895/62. Heading B5N. Two sheets of material, each having at least one thermoplastic surface, are laminated together by passing them, thermoplastic surfaces in contact, through the nip of a pair of rollers and heating the adjacent surfaces, immediately before passage through the nip, by a highspeed stream of hot gas; the rollers are unheated and the pressure applied and speed of the sheets are adjusted to secure fusing of the adjacent thermoplastic surfaces without thermal damage to the sheets. As shown, webs 18, 20 of belting fabric coated with thermplastic material 19, 21, are advanced around rollers 14 . . . 17 and thence to the nip of pressure rollers 10, 11. During their travel around the latter rollers they are subjected to jets of hot air from a nozzle 26 of shape substantially that of the rollers. The thermoplastic coatings are thereby raised to fusing temperature without detrimentally heating the fabric substrates. The rollers 10, 11 are hollow for circulation of cooling fluid 28. The roller 10 is rockably mounted about a pivot 12 to adjust the pressure at the nip, rocking being effected by an hydraulic piston 23 the cylinder of which is mounted in a shackle and which is connected to a head 24. Rollers 14 and 17 are tiltable in their common plane by mechanism 26<SP>1</SP>, 27<SP>1</SP> to ensure exact registering of the two webs. In a modified apparatus for bonding a web of foamed material to a thermoplastic web, the foamed web is coated with thermoplastic material and advanced on a wire mesh endless belt to the nip of pressure rollers mounted as described above. The thermoplastic web is fed around the upper roller, and at or near the nip the surfaces to be bonded are heated by jets of hot air supplied through apertures in a chest having walls roughly parallel with the horizontal foam web and the upper roller respectively. Specification 968,156 is referred to.

Class 75 (3) A gas stove or similar gas burning apparatus provided with an electric spark ignition device lying within the range of a pilot-light gas jet has a magnetic armature attached to the stove for producing the high tension voltage actuated by means of a spring draw-bar or similar device. The ignition unit 1 is connected to a pipe 3a branching off a main gas pipe 3 through a regulator valve 4 and a spring biased valve 5b. The apparatus is operated by means of a draw-bar 10 loaded by means of a spring 9 and attached to a toothed bar 8 so that when the bar 10 is pulled outwardly against the spring 9 the spring biased valve 5b is opened, by a bracket 8a abutting a stop 8b, to allow gas to pass to the unit 1 and the magnet is rotated through a pinion 11a. When the bar 10 is released the spring 9 quickly returns the bars 8, 10 to their normal position, compression springs 7, 6 close the valve 5b and the pinion 11a rapidly rotates the magnet to create a spark across a gap 12 and thus ignite the gas issuing from the pilot unit 1. In an alternative arrangement, Fig. 3 and 4 (not shown), the valve is arranged perpendicularly to the bar and is opened by an oblique surface on the bar. The movement of the magnet may be dependent on the movement of the valve plunger.

Title: Improvements in and relating to synthetic resinous compositions
Inventor: STURM ROBERT HEINRICH
IPC: C09D161/34
Filed: 1946-05-29
Abstract: A synthetic resinous coating composition consists of an inter-condensation product of a saturated cyclic ketone of the cyclohexane series or a mixture of such ketones with an aldehyde, a phenol and urea or melamine in butyl or octyl alcohol alone or admixed with alcohols containing 5 to 7 carbon atoms.  Phenol and the ketone, e.g. cyclohexanone or methyl cyclohexanone are condensed with hexamethylenetetramine or with formaldehyde and a basic catalyst in presence of butyl or octyl alcohol or a mixture thereof with up to 50 per cent of alcohols with 5-7 carbon atoms. Up to 1 mol. of phenol is used for 2.5 mols. of formaldehyde.  The condensation is arrested when the viscosity begins to rise sharply by acidification to pH of 5.5 to 6 with a mixture of 2 parts of salicylic acid and 1 of lactic acid, or with a sulphonic acid such as benzene- or p-toluene sulphonic acid or with oxalic acid.  Urea in the proportion of 2-4 mols. per mol. of phenol is dissolved in neutralized formaldehyde and added to acidified condensate and condensation is continued.  Water is removed by vacuum distillation, 4-8 per cent being left in the mixture.  A mixture of solvents, e.g. ethylene glycol monobutyl ether and benzene is added to form a ternary solvent system with the residual water in the mixture.  The pH is finally adjusted to 4.5. Using melamine in place of urea, a smaller molar percentage is employed in relation to the phenol and the final pH is adjusted to 4.2.  The compositions are compatible with plasticizing resins of the non-drying alkyd types.  They are particularly suitable for application to mouldings or laminates of thermosetting materials.

Abstract: 560,339. Hose suspender grips. LILLIE, E. A. (Hawie, M.). Nov. 19, 1942, Nos. 16377/42 and 4521/43. [Class 44] In a hose suspender of button-and-loop type the button or stud is made of metal, plastic, or other non-rubber material and has a covering of textile, leather, or like flexible non-rubber material. This covering is provided by the tape or like tab on which the button element is mounted. The button element comprises a plate 1 to which the stud 3 with domed head 2 is riveted by an integral rivet portion 7, the plate having a slot 4 shown as semicircular and concentric with the stud. The supporting tape 8 is passed through the attachment loop 14 over the ferrule 12 connecting that loop with the usual gripping loop 13 which co-operates with the stud, and passed down behind plate 1, up over the button head, and is then threaded rearwardly through slot 4. The ends of the tape overlap and are secured together and to the other part of the tape by stitches 17, 19. The stud is thus enclosed in a loop of fabric which may be folded before application to provide a covering 'of double-thickness as shown. The curved slot curves the tape transversely to fit closely to the stud as seen in Fig. 3. The Specification illustrates an alternative arrangement in which the covering is of single thickness and a modification in which the tape is laid on the front face of plate 1 before the stud is riveted thereto, so that the tape is secured between the inner end of the stud and the plate. The ends of the tape, instead of being secured by stitches, are gripped by the ferrule 12. The tape in the region of the stud may be preformed with a bulge in which the stud head is received.
