Title: Improvements in devices for the insertion of wooden sticks in bodies of ice cream
IPC: A23G9/26
Filed: 1945-11-20
Abstract: 600,233. Feeding sticks from piles. GRAM, A. G., and GRAM AKTIESELSKABET, B. Nov. 20, 1945, No. 31166. [Class 117] Apparatus for feeding wooden sticks in succession from a pack, for use with portions of ice cream, comprises one or more shoots 1 each containing sticks 2 pressed by a weight 3 towards a slit 10 in a frame 5. The slit except for a portion near the centre of its height is comparatively wide directly opposite the discharge end of the shoot but has a lateral extension decreasing in width down to a width substantially equal to that of a stick, at a position between a plunger 7 and a discharge channel 8. The arrangement is such that a stick, which may be slightly curved is fed from each shoot onto a slit 10, moved laterally by a hooked member 13, straightened as the width of the slit decreases, and then discharged through a channel 8 by a plunger 7. Spring-pressed members 17, 15 engage one side of the stick during its travel. The member 13 is reciprocated across the outlets from the shoots by a lever 19 coupled to a piston 22. Each plunger 7 is reciprocated by a lever 23 coupled to a piston 24. To assist the weight 3 in the discharge of the sticks two members 29, 30 are provided for pressing intermittently the sticks towards the shoot outlets. The member 30 comprises a spring-pressed rod one end of which is pressed against a stick during part of the movement of lever 23. The member 29 comprises a sector eccentrically mounted on a pin 36 and adapted through the medium of a spring-pressed rod 39 and a casing 40 suspended from a bracket connected operatively with the plungers 7, to engage the edges of certain sticks and press them towards the discharge outlet during upward movement of the plungers.

Title: High performance quality controlled bipolar membrane
IPC: C08F8/00
Filed: 1977-07-26
Abstract: Improved novel single film bipolar membranes having an ion selectivity above 80% in an electrolyte medium of about one mole, are prepared containing a relatively high amount, i.e. at least 15% of an insoluble cross-linked aromatic polymer. Before the styrenated sheet is chemically functionalized, the film surface is specifically treated, i.e. cleaned to make it more receptive to functional groups, so that the cationic-exchange groups and anion-exchange groups can be introduced homogeneously from each side of the surface-cleaned film, and a single-film bipolar membrane of superior durability, stability, and quality control results.

Title: Improved rotatable brake drum
Inventor: ALDEN JOHN HAROLD
IPC: F16D65/833
Filed: 1957-10-09
Abstract: 835,094. Cooling brake drums. VAUXHALL MOTORS Ltd. Oct. 7, 1958 [Oct. 9, 1957], No. 31544/57. Class 103 (1). In a brake drum provided with an enclosed annular chamber 16 partially filled with coolant liquid, the inner surface 19 of the outer wall 14 is provided with a series of adjacent partcylindrical undulating surfaces 20 such that, when the drum 10 is rotated at high speed, the coolant liquid accumulates against the undulating internal surface 19 of the outer wall 14 of the rim portion 11 of the drum and out of contact with the internal surface 25 of the inner wall 15. Upon application of the brake shoes (not shown) to the friction surface 18 of the inner wall 15, the temperature of the inner wall 15 of the rim portion of the drum rises and, due to its angular momentum, the liquid in chamber 16 tends to continue rotating at the former speed of rotation of the drum. This causes the liquid accumulated in the recesses formed by the surfaces 20 to move peripherally along the undulations and thus to be moved radially inwards to be directed on to the internal surface 25 of the inner wall 15 to cool the latter.

Abstract: 825,231. Testing physical qualities of materials. MINISTER OF SUPPLY. Jan. 17, 1958 [Oct. 19, 1956], No. 31858/56. Class 106 (2). [Also in Group XXXV] A method of determining the energy absorption characteristics of a specimen 9 of a polymeric material secured on a mounting 8 in a chamber 16 comprises dropping a body from a known height on to the specimen and observing the height of rebound, this test being repeated for different specimen temperatures. The specimen is heated by an electric heater 13 and cooled by an inert gas, such as cold carbon dioxide, directed on its surface by a tube 18, a thermo-couple 11 indicating the temperature and the chamber 16 being evacuated during the test. A steel ball (not shown) is raised by an electromagnetic lift 21 and allowed to fall on the specimen 9, the height of rebound being indicated by viewing it against an illuminated scale 22. The steel ball falls on to an inclined plate 19 and is raised again by the electromagnets 21, the whole operation being repeated at least twice a minute. This is stated to be of use in determining, among other properties, the degree of cure of a resin, the crystallinity of crystalline polymeric materials or the identity of a polymer.

Title: Improvements relating to ignition devices
Inventor: GUENIN LEANDRE ANDRE
IPC: F23Q1/02
Filed: 1967-07-11
Abstract: 1,249,101. Igniters. L. A. GUENIN. 10 Oct., 1968 [11 July, 1967], No. 31919/67. Heading F4F. A cartridge in an igniter suitable for e.g. a smoker's lighter, has a perforated drum 6 containing pyrophoric or hypergolic material e.g. aluminium borohydride, held in fibrous material e.g. glass fibre 5, inside a case 1, the case having a discharge orifice normally closed by the head 10 of an obturator 8 under the action of a spring 9 and containing an inertial member 11 movable therein towards the obturator to momentarily open the discharge orifice by virtue only of its inertia, without requiring mechanical connection with any element external of the case via the passage of an operating member through the case wall, before being returned to its rest position by a spring 12. A screw cap 4 and resilient washer 3 secure the cartridge normally against a shoulder 2a in a tubular holder 2 which is also provided with a hammer 18 normally held by a spring bar 20. On depressing a button 15 in the holder 2 against a return spring 16 and a spring 19 acting between the button 15 and hammer 18, a rim 17 on the button bears on an inclined surface 21 On the claw 20 to free the hammer which strikes the cartridge. The cartridge moves against the washer 3 and the inertial member 11 is displaced relative to the cartridge to hit the obturator and open the orifice. A saucer shaped washer 22 is secured to one face of the member 11 and acts as a one-way valve for passage of the pyrophoric material. In a modification, Fig. 2 (not shown), the spring 19 acts directly on the base of the cartridge which is contained within a sleeve releasable from a spring claw by actuation of the button, so that both cartridge and sleeve move towards the orifice until checked by engagement of a rim of the sleeve with a shoulder in the holder and the member 11 continues until it strikes the obturator. In a further modification, Fig. 3 (not shown) the obturator is combined with the inertial member and the movement of the cartridge is so arranged that on checking it suddenly the obturator moves inwards of the orifice. In another embodiment, Fig 4, the actuator 39 has a magnetic coupler 36 movable on shafts 37 against springs 38 and partly surrounding the cartridge. The coupler 36 and member 11 are of ferromagnetic material, one or both being a permanent magnet and the cartridge case 1 is of non-magnetic material e.g. aluminium. Depression of the coupler 36 moves member 11 against a spring 40 until the force of the latter overcomes the magnetic force between the member and coupler when the member is propelled towards, and strikes, the obturator 8. In yet another embodiment, Fig. 7 (not shown), the drum containing the pyrophoric material is free to move inside the cartridge case against a spring. One end of the drum includes an integral obturator, the other end has a projection engaged in a diaphragm for guiding the drum, and the entire drum acts as the inertial member.

Title: Process for the manufacture of salts or other derivatives of aromatic dicarboxylic acids, especially of terephthalic acid
IPC: C07C51/15
Filed: 1953-11-20
Abstract: Salts or other derivatives of aromatic dicarboxylic acids are prepared by a process which includes the step of heating the potassium salt of an aromatic monocarboxylic acid in the presence of carbon dioxide, to obtain a potassium salt of an aromatic dicarboxylic acid.  The temperature used is above 340 DEG  C. in order to obtain a reasonable rate of reaction, and to avoid oxidation the heating is carried out in the presence of carbon dioxide, usually under pressure in an autoclave fitted with a stirrer. Specified starting materials are potassium benzoate and naphthoates and these may be mixed with inert substances such as sand or inert salts such as potassium carbonate, sulphate or chloride.  The salts obtained may be converted directly by known methods into derivatives such as the dichlorides and esters.  The reaction is promoted by metal, e.g. lead, zinc, or mercury, or metal oxide catalysts.  The process yields are calculated on the theory that, for example, 2 molecules of benzoic acid are converted into one molecule of terephthalic acid and 1 molecule of benzene.  In examples (1-8) potassium terephthalate and terephthalic acid are prepared from potassium benzoate using various catalysts and reaction conditions; (9-11) potassium a - and b -naphthoates are converted into naphthalene-2:6-dicarboxylic acid and the corresponding potassium salt.
