Title: Improvements relating to the gauging of biscuits
Inventor: MORTON DAVID CHARLES
IPC: A21C15/00
Filed: 1963-03-29
Abstract: 1,049,873. Gauging biscuits. BAKER PERKINS Ltd. March 26, 1964 [March 29, 1963], No. 12601/63. Heading A2A. [Also in Division G1] A device for gauging the diameter of substantially circular biscuits comprises an inclined shoot 5, Fig. 1, having a side-wall 9, Fig. 3, which is lower and slopes upwardly from the other side-wall 14, so that each biscuit 1, fed into the upper end of the shoot from a conveyer 2 and over a guide plate 8, rolls down the shoot with the edge of the biscuit in rolling contact with the lower side-wall 9 and in sliding contact with the upper side-wall 14. Each biscuit is supported, in the upper portion 12 of the shoot, by a continuous support extending between the bases of the sidewalls, and, in the lower portion of the shoot by a ledge 13 on the side-wall 9. In the lower portion of the shoot, the distance between the biscuit-contacting lower portions of the side-walls is equal to the minimum acceptable diameter of a biscuit, so that biscuits under this diameter fall through the gap between the side-walls. Acceptable biscuits roll down the whole length of the shoot, e.g. over any biscuit that may become jammed therein, and are discharged on to a conveyer 3.

Abstract: 586,733. Electric lamp caps. BRITISH THOMSON-HOUSTON CO., Ltd. July 3, 1944, No. 12642. Convention date, July 1, 1943. [Class 39 (ii)] [Also in Group XXXVI] A bulb for electric incandescent lamps and discharge tubes is provided with a screw threaded neck to receive a similarly threaded metal cap which is screwed thereon and held against disengagement by a film of adhesive provided between the engaging surfaces, and one of the leading-in wires is mechanically clamped into electrical contact with the cap while the other is mechanically clamped to a centre or end contact which is located in insulating material closing the end of the cap. In one method of clamping the leading-in wire 15 to a cap B, Fig. 3, the screw threads in the bulb neck 10 are traversed by a groove 30 which runs vertically across them the wire being brought across the closed end 13 of the neck and down the groove, so that when the cap is screwed in position its corrugations bear upon the wire, the depth of the groove in the neck being such that the wire is flexed resiliently by the pressure on it. The centre contact comprises a rivet-like metal eyelet with a hollow shank 26 secured within a vitreous conical mass 21 which closes the end of the cap, the upper end of the shank having a disc or flange 25 formed with a radial slit 27 so that one adjacent edge of the metal can be turned upwardly to form a tongue beneath which the upper end of the leading-in wire 16 is bent after bringing it up through the central hole, and' is then bent around the shank and clamped by pressure upon the disc 25. The adhesive 34 applied between the cap and the neck of the bulb L may be of the varnish type, comprising rubber, gum, resin &c. in a suitable volatile solvent, or may consist of a water soluble silicate or a slow setting gum or plastic. In a modification, Fig. 4, the end insulator 21a supporting the centre contact 25a consists of a bevelled button, preferably of glass, secured in the upper end of the cap by turning the latter inwardly to form an annular lip 36 which overhangs the bevelled edge, the leading-in wire 15 being clamped between the edge and an annular seat 35 produced in the formation of the lip 36. In a further modification, Fig. 5 (not shown) the overhanging annular lip is replaced by a series of metal tongues, e.g., three, which project inwardly and engage within notches in the adjacent edge of the insulating button supporting the centre contact, this engagement also serving to clamp one leading-in wire against the rim of the cap. The centre contact comprises a resilient cylindrical member with a head which clamps its leading-in wire in position by a snap-action. Specification 424,621 is referred to.

IPC: B29C61/00
Filed: 1945-05-23
Abstract: <PICT:0606963/IV(a)/1> Container closures are made by forming tubing from a thermoplastic resin composition comprising a thermosetting material in the thermoplastic state, stretching the tubing transversely and severing it into bands, which may then be applied to a container and caused to shrink thereon by heating.  The resin composition may consist of a thermosetting resin in the thermoplastic state, together with a thermoplastic resin or thermoplastic cellulose derivative, and plasticisers and latent catalysts for the thermosetting resin may be included.  The thermosetting resins may be alkyd resins, drying-oil-modified alkyd resins, sulphonamidealdehyde resins, phenol-aldehyde resins, ureaaldehyde resins, etherified urea-aldehyde resins, melamine-aldehyde resins, or mixtures of such resins.  The thermoplastic resins may comprise polymers of vinyl acetate or chloride or of vinylidene chloride, after-chlorinated vinyl polymers, the polyvinyl formals, acetals and butyrals, polystyrene, resins formed from esters of acrylic acid and methacrylic acid, copolymers of vinyl chloride and acetate, of vinylidene chloride and vinyl chloride, of vinyl halide and an acrylic acid derivative, or of a vinyl compound and styrol; or resins formed from dicarboxylic acids and diamines.  The thermoplastic cellulose derivatives may include the organic solvent soluble cellulose esters or ethers such as cellulose acetate or butyrate, nitrocellulose, alkyl-, carboxy-alkyl and hydroxyalkyl cellulose ethers, and mixed ether-esters of cellulose.  Latent catalysts for acid-curing thermosetting resins may include salts of chloracetic acid, ammonium salts of strong acids, ammonium thiocyanate and p-toluene sulphonic acid.  For alkali-curing thermosetting resins sodium carbonate, ammonia, alkali sulphites, cupric hydroxide, aluminium hydroxide, pyridine, sodium cyanide, guanidine carbonate and pyridine dithiocarbamate may be used.  As plasticisers dibutyl sebacate, dibutyl phthalate, tricresyl phosphate, dicyclohexyl phthalate, methyl cellosolve acetyl ricinoleate, thermoplastic alkyd resins, linseed oil, blown rapeseed oil and soy bean oil may be included. The tubing is made by extruding the resin composition, rendered fluid by heat or by the addition of a solvent which is subsequently evaporated, through the orifice 13 of an extrusion head 11 having a hollow central mandrel 17 through which water or compressed air may be introduced to expand the tubing 15, which is then flattened and cut into short lengths.  Window band may be produced by dividing the die into quadrants and extruding an opaque composition through opposed quadrants.

Title: Follow-up system for microwave antennae
IPC: H01P5/16
Filed: 1973-03-19
Abstract: 1412352 Mode couplers LICENTIA-PATENT VERWALTUNGS GmbH 19 March 1973 [17 March 1972] 13083/73 Heading H1W [Also in Division H4] A direction-finder system, in which higher order modes produced in a waveguide are utilized to provide azimuth and elevation angular deviation data concerning a distant transmitter, comprises a transistion between an aerial feed waveguide of non-square crosssection, e.g. circular, or cruciform, or octagonal and a succeeding waveguide of square crosssection, and a mode coupler adapted to extract the deviation data from the received signal. The mode coupler may be provided with a branch network and the deviation data signal be applied to a comparator network. The system may be used with either linearly or circularly polarized radiation, and it is particularly suitable for tracking a communications satellite from a ground station. As described, a mode coupler H, Figs. 4, 5, comprises a square cross-section wave guiding member tapering from its front part, where it receives any H 20  and H 02  mode waves from the square cross-section waveguide (arising from angular deviations of the transmitter), to its rear part. The H 20  and H 02  mode waves are capable of propagation only in the front part of the coupler, so that standing waves are set up which are coupled out by eight elements K1 to K4 (H 20  waves) and K5 to K8 (H 02  waves). The couplers comprise longitudinally extending bars B which are evenly spaced around the coupler, as shown. Each bar is connected at its middle to a co-axial wave guide member L, which extends to a coupling loop in a cavity HO. The pairs of elements (K1, K2), (K3, K4), (K5, K6), (K7, K8) provide inputs to respective hybrids HY1, HY2, HY3, HY4, in which said cavities HO are comprised. Outputs from the hybrids HY1, HY2 are combined in a hybrid HY5 to provide at a port 4 thereof an output PH20 equivalent in amplitude to the original H 20  waves. The hybrids HY3, HY4 are similarly coupled to a hybrid HY6, and an output PHO2 equivalent in amplitude to the original H 02  waves appears at a port 4 thereof. In a first arrangement for processing the PH20 and PH02 outputs they are combined in a directional coupler R, Fig. 10, having variable coupling attenuation α K . A variable phase shifter Ph is inserted in the PH02 line. The directional coupler R provides outputs which are respresentative of the angular deviations of the transmitter in orthogonally disposed planes. In a second arrangement, the PH20 and PH02 outputs are coupled through a hybrid (HY7), Fig. 11 (not shown), and in a third arrangement the outputs from that hybrid are coupled through a further hybrid (HY8), Fig. 12 (not shown), a variable phase shifter and a variable attenuator being connected in circuit between the said two hybrids.
