Abstract: 664,881. Cutting blocks from a strip of ice-cream &c. ROSE BROTHERS (GAINSBOROUGH), Ltd. Aug. 30, 1950 [Sept. 2, 1949], No. 22732/49. Class 87(ii) A strip of ice-cream is emptied from a mould on to a pivoted part of a feed stack 11 which has been moved into a horizontal position (shown dotted). The part is then raised to tip the strip of ice-cream into the stack and to close the stack. The strip is cut into blocks 14 by a knife 13. The pivoted part is held in its closed position by a spring plunger 28. The hinge is arranged a sufficient height from the bottom of the stack to allow enough icecream to be left in the stack for continuous cutting, while the stack is being filled.

A dual hardness resilient spring element, e.g. for a vehicle suspension system, and made of rubber or other elastomer comprises a hard homogeneous cylindrical member 1 for absorbing the high compressive forces and which is secured, e.g. by vulcanizing or cementing, to a relatively softer cellular buffer member 2 which is preferably formed of a foamed polyurethane and is for absorbing the low initial forces. The inner surface of the member 1 is formed as a bellows the action of which is assisted by an outer annular groove 8. A groove 9 provides means for connection to a supporting cap member, not shown. Fig. 2 shows a pot-shaped cylindrical member having a flat buffer member 2 which closes a hollow space 4. The member 1 carries a sheet metal cap 10 with a fixing pin 11. In an alternative arrangement the inside wall of the member 1 is curved outwardly and the buffer member 2 is of conical shape. Fig. 4 shows two resilient elements in combination. In double arrangements of this kind the buffer members 2 may also be formed as hollow bodies.

Abstract: 1,071,431. Semi-conductor arrangement. TELEFUNKEN PATENTVERWEBTUNGS G.m.b.H. June 3, 1964 [July 22, 1963], No. 22981/64. Heading H1K. In a semi-conductor arrangement housing at least one transistor the electrode supply conductors comprise a central conductor surrounded by an inner and an outer conductor. Two transistors 8 are mounted on a plate 1 within a casing cap 2 and a cooling body 3. Electrode supply conductors 4, 5 and 6 are arranged coaxially, conductor 4 being a massive wire while conductors 5 and 6 are tubular. If the transistor is base connected, then conductor 5 supplies the base while conductor 4 supplies the emitter, the complete connections being made by wires 9 and 10 respectively. If the transistor is emitter connected then conductor 5 supplies the emitter while conductor 4 supplies the base. To keep the wires connecting the electrodes and the conductors as short as possible, flanges are made on the conductors e.g. 11 on 4. The intermediate wires should preferably be of equal length in all cases. If non-tubular conductors are used then these may be with a contact plate to facilitate connection with the electrodes. The transistors may be of the mesa type.

Title: Coaxial illuminator for stereomicroscope by polarization
IPC: G02B21/00
Filed: 1967-05-17
Abstract: 1,136,705. Stereo-microscopes. BAUSCH & LOMB Inc. May 17, 1967 [June 13, 1966], No. 22988/67. Heading G2J. A stereo-microscope having a pair of axes 12, 13, on which are respectively aligned a complex objective 10, 11, abeam divider 27, 27', for providing episcopic illumination from lamps 23, 23', and an eyepiece 19, 19', has polarizing members 28, 28' to prevent light which is back reflected from the objectives from degrading the image contrast. As shown, the optical systems 10, 11, consist of an objective section 15, 15', and a zoom section 16, 16'. Each member 28, 28', has a plane polarizing element 28a, 28a' similarly oriented as indicated by arrows 29, 29', and a /4 plate 28b, 28b' for rotating the axis of polarisation through 45 degrees but in different senses in the two plates as indicated by arrows 30, 30'. Thus light from lamp 23' is plane polarized by element 28a' as indicated by arrow 29', rotated by /4 plate 28b' to position 30', illuminates object 0, is rotated 45 degrees by /4 plate 28b and thus has its axis of polarization as indicated by arrow 29 and so is accepted by element 28a and passed to eye-piece 19. Similarly light from lamp 23 after illuminating the object 0 is passed to eyepiece 19'. However, light reflected back from surfaces of the lens system 10, 11, is so rotated by the /4 plates 28b, 28b', that its axis of polarization is perpendicular to arrows 29, 29' respectively and thus is extinguished. In a modification, Fig. 2 (not shown) the two /4 plates (31b, 31b') rotate the vibration axis in the same direction and the plane polarizers (31a, 31a') have their vibration axes (32, 32') at 90 degrees to one another.

There are a plurality of units APX each transmitting serial data signals to the preprocessing network RPE where they are received in parallel and converted to serial form via a further core matrix read-out in rows to an intermediate register producing a parallel code for each signal, these codes being for example digits entered at an operator keyboard. An adaptor not shown receives such parallel signals discriminates against noise in a manner not detailed, transmits true codes to the processor via a code converter and transmits polarity transitions due to cord engagements, meter pulses &c. direct to the processor. Each operator has an identification code and inserts a printed circuit identification card into a card reader the code from the latter being converted to serial form in network RPE. Lamp signals including fault signals are returned to the switchboards after decoding in RPE. It is stated that statistical data can be also compiled.

Abstract: A composition comprising carbon and heat-refractory material such as baddeleyite, zirconium oxide, silicon carbide, titanium oxide or carbide, rutile, magnesium oxide, fused magnesia, thorium oxide, corundum or aluminium oxide is protected against deleterious effects of high temperature by mixing therewith a solution of a salt of a high-melting-point metal or of boron and heating the mixture to a sufficiently high temperature-e.g. 1000-1200 DEG  C.- to convert the salt to an oxide or carbide. Salts of tungsten, zirconium, boron and manganese-e.g. a 15 per cent solution of tungsten or magnesium nitrate in alcohol may be used.  When a boron salt solution is used, boron carbide is formed.  The mixing may be performed in vacuo.  The mixture of refractory, carbon, and oxide or carbide may be compacted with a binder-e.g. aluminium or magnesium silicate, bentonite or aluminous cements.  The carbon may be deposited in situ in the heat-refractory material by heating the latter, immersed in oil, in a closed chamber.  U.S.A. Specification 1,947,692 is referred to.

Aqueous dispersions of vinyl ester polymers are produced by polymerizing at least one vinyl ester of a monocarboxylic acid with 2 to 19 carbon atoms, alone or in the presence of up to 35% by weight of at least one other mono-olefinically unsaturated monomer, in an aqueous phase, suitably at 40‹ to 95‹ C., using a watersoluble free radical polymerization catalyst in the presence of, as protective colloid, a reaction product of polyvinyl alcohol and 0À1 to 10% by weight of at least one mono-olefinically unsaturated aldehyde containing 3 to 8 carbon atoms, the final dispersion containing 0À5-15% of colloid. The polyvinyl alcohols are saponification products of vinyl ester homopolymers, or copolymers or graft polymers, many of which polymers are specified. Specified aldehydes are but - 3 - en - 1 - al, pent - 2 - en - 1 - al, tiglic aldehyde, hex-2-en-1-al, acrolein, α-ethyl-, α- methyl-, #-ethyl-, and α-propylacrolein, and crotonic aldehyde. Specified comonomers are acrylic acid, methacrylic acid, maleic acid, fumaric acid, and esters of these acids with aliphatic monohydric saturated alcohols containing 1 to 10 carbon atoms, and also acrylamide, methacrylamide, crotonic acid, and vinyl chloride. The modified polyvinyl alcohol may be obtained by subjecting the vinyl ester polymers, in methanol and in the presence of alkaline or acid catalysts, to an alcoholysis, and reacting the polyvinyl alcohol obtained, in the presence of acid catalysts and at an elevated temperature, with the unsaturated aldehyde(s). Additional emulsifiers and protective colloids may also be present, e.g. an N-vinyl-N-methylacetamide - 2 - ethylhexyl - acrylate copolymer. Vinyl ester polymers produced in the examples are those of (1), (2) vinyl acetate, (3) vinyl propionate, and (4) vinyl acetate, vinyl ester of branched aliphatic monocarboxylic acids having 9 to 19 carbon atoms, and acrylamide. In comparative examples, unmodified polyvinyl alcohols are used (1A, 2B, 3B), and polyvinyl alcohols modified with saturated aldehydes (1G, 1H-butyraldehyde, 4B - acetaldehyde). The dispersions may be used as adhesives.
