Title: Photoelectric reproducing head for an optical sound reproducer
IPC: G11B7/085
Filed: 1972-07-19
Abstract: 1369763 Photo-electrically reading a sound record GAKKEN CO Ltd 19 July 1972 31368/73 Divided out of 1369761 Heading G1A Light from a lamp 58, Fig. 7, near one end of a cylindrical housing 52 passes through a converging lens system 59, 62 within the housing and through a slit 57 in the other end of the housing and is reflected from an optical sound track on to the light-sensitive surface of a plate-like photo-electric element 53 which is not directly exposed to light transmitted by the lens system from the lamp 58. The slit 57 may be between two photo-electric elements, in a single element, or between a single element and a screen. In a playback apparatus, Fig. 3, such a head 50 moves along a slot 74 in a rotating turn-table 33 so as to scan a spiral optical sound track on the underside of a stationary sheet record 20, as described in Specification 1369762.

Title: Improvements in or relating to duplicating
IPC: B41L19/00
Filed: 1965-07-22
Abstract: 1,065,507. Hectograph printing. M. SHARKEY. July 22, 1965 [July 22. 1964], No. 31375/65. Heading B6C. A hectograph master sheet 10 comprises a paper foundation sheet 11 with a coating 12 which is substantially non-pressure transferable and which contains at least one solid material which in its melted state is a solvent for hectograph dyestuff, and having on the coating an image 13 of hectograph composition which has a higher melting point than the coating and contains undissolved hectograph dyestuff. When the master sheet is placed in contact with a copy sheet and heat is applied at a temperature sufficient to melt the coating 12 but not the image composition, some of the image composition is dissolved in some of the coating 12 and is transferred to the copy sheet. The copy sheet or the master sheet may be preheated to effect the melting of the coating 12 or one of a pair of cylinders (20, 30, Fig. 2) between which the sheets are passed may be electrically heated. Infra-red radiation (22) may be employed as the heating means, in which case the master sheet contains a dark pigment to absorb the radiations. The copy sheet may have a dark back coating for the same purpose. The copy and master sheets may be in long lengths (Fig. 3) for printing garment patterns. The coating 12 may include as its meltable solvent constituent solid fatty substances such as cetyl, myristyl and stearyl alcohols, solid fatty acids such as stearic, palmitic, lauric and capric, solid esters of various glycols and organic acids, and solid glycol ethers such as polyethylene and polypropylene-glycol ethers. Small amounts of wax binder materials may be incorporated in the coating.

Title: Improvements relating to cement, grout or concrete placers
IPC: F04B15/02
Filed: 1933-11-13
Abstract: 427,566. Pumps for concrete. KIRBY, M. R., Bridge House, Wentbridge, Pontefract, Yorkshire, and STEWART, A., 35, Broom Water, Teddington, Middlesex. Nov. 13, 1933, No. 31597. [Class 102 (i)] In a pump for cement or concrete the cylinder is moved about a longitudinal or transverse axis in order to effect registration of the cylinder with supply and discharge ports. The piston 14, Fig. 1, in the material cylinder 10 is operated by a piston 13 in a power cylinder 11. The latter can be oscillated about a pin 18 supported in a bearing 19, while the cylinder 10 can oscillate about a pin 8 carried by a pedestal 4, which also carries the supply hopper 2 and the discharge outlet 5. A semicircular plate 20, secured to the cylinder 10 and having a port opening to the cylinder, is mounted on the pin 8 and can be oscillated by means of a handle 24 to effect registration of the cylinder with the supply and discharge ports. Ports in the cylinder 11 may co-operate with ports in an end plate to effect distribution of motive fluid to the cylinder 11. In a modification, Fig. 8, the cylinders are oscillated by a rod 71 carrying pistons 69, 70. In the position shown motive fluid is admitted by the valve 63 to the piston 70 to move it to the left and oscillate the cylinders. When the piston 70 passes the passage 72 motive fluid is admitted to the cylinder 11 to move the piston 13 to the right and draw in a charge into the material cylinder 10. At the same time the right-hand end of the cylinder 11 exhausts through passages 73 and 75. At the end of the stroke a lever 64, pivoted to the piston-rod 15, moves the valve 63 to the left and the return stroke takes place. In the modification shown in Fig. 4, the material cylinder 10 oscillates about an axis 28 and carries an end plate 31, which co-operates with the outlet from the hopper 2 and with the discharge port 5. The cylinder is moved by a link 51 from a bell-crank 50, which is operated by a rod 46 from a grooved cam 42 on the driving shaft 38. A crank 37 on the latter drives a forked connecting-rod 36, which is pivoted to a sleeve 35 sliding on the exterior of the cylinder 10. The sleeve 35 is connected by links to a pin 33 carried by the piston rod of the cylinder 10 and passing through slots in the cylinder.

Specified vinyl monomers are vinyl acetate, vinyl chloride, and styrene.  The graft copolymer may be a polymer of styrene, acrylonitrile, vinyl or vinylidene chloride with polyvinyl alcohol, polyacrylamide, polyacrylic acid, or a vinyl acetate polymer.  Exemplified graft polymers are vinyl chloride-polyvinyl alcohol, styrene-polyvinyl alcohol, styrene-polyacrylic acid, and styrene-polyacrylamide.

Abstract: 1356255 Ignition jet RADIATION Ltd 23 June 1971 [2 July 1970] 32161/70 Heading F4F An ignition jet for lighting a plurality of gas burners of an appliance which are located in different directions from the jet comprises main flame ports 70 associated with the respective burners, an annular auxiliary carrier and retention flame port 69 and a gas supply duct 72 feeding the main ports 70, the auxiliary port 69 being in restricted communication with the duct through orifices 76. The main ports 70 are formed in a cap 68 screwed to a mounting member 67 which co-operates with a supply member 66 to define the auxiliary port 69. The port 69 is provided with a washer 80, e.g. of expanded metal, to equalize gas flow and serves to ensure lighting of the main ports and, in the case of natural gas, retention of the main flames. When natural gas is used a restrictor 79 is fitted, a wire is inserted in orifices 76 and a cap 68 having suitably sized flame ports is fitted. In the Fig. 7 embodiment the main flame ports 143 and auxiliary ports 145 are fed through two bores 134 and 135 of different cross-sectional areas and a cross bore 136 sealed by a screw 137. For natural gas a longer screw 138 is inserted to block the entrance to the bore 135. In a third embodiment a flame distribution head which provides the main flame ports is screwed into a counterbore in a supply member and a notched knife-edge at the end of the distribution head is thereby crushed to restrict the notch. In a fourth embodiment a supply member carries at its end through the intermediary of a castellated disc an inverted cup whose depending skirt portion defines with the periphery of the supply member an annular auxiliary flame port above the main flame ports which are formed in the supply member. In use the ignition jet is fed by any of four pipes when the appropriate control tap for one of four burners on a hotplate is turned past the " full-on " position and is then ignited by a permanent pilot, glow coil or spark igniter to send out long ignition flames to the four burners. Alternatively a spring-loaded pushbutton device may be used to open a gas valve in a gas line to the ignition jet.
