Title: Method and apparatus for making rings of dough
IPC: A21C3/00
Filed: 1973-06-11
Abstract: 1430112 Moulding dough rings ENTENMANNS BAKERY Inc 11 June 1973 [3 July 1972] 27771/73 Heading B5A In a machine for moulding dough rings a number of open topped cylindrical moulds 8, Fig. 9, are continuously advanced by an endless conveyer 4 and simultaneously rotated about their vertical axes when receiving a length of twisted dough 22 from a supply 6. Each dough length extends along one side and above the path of travel of the moulds and is lowered progressively into the appropriate mould by a baffle assembly 28, Fig. 4, comprising a fixed baffle 30 and three movable downwardly indined baffles 31-33, the latter receiving the dough length in sequence to guide it into the rotating mould cavity whereby it is wound into the cavity. The feeding stage may be preceded by the automatic supply to each mould of material such as nuts from a dispenser 16, Fig. 9, followed by a brushing action by a brush 20. After dough delivery a member 24 is lowered to compress the dough ring and unite its ends. During the compression the mould continues its lateral movement, but its rotation is terminated by the disengagement of a mould drive sprocket 26c from a fixed chain 26d. The compressed ring is discharged into a baking tray 14 when the mould is inverted and an annular ejector plate 40 lowered by air cylinders, not shown. A web 58 prevents premature discharge of the ring. The baffles 31-33, Figs 4, 11, are supported by spring-urged members 36a, 36b, 36c respectively, pivoted at their lower ends and moved sequentially from the fixed baffle by followers 36d, 36e and 36f respectively moved outwardly by their engagement with the travelling moulds. The pressing member 24 is secured to means slidable on rods 54, Fig. 2, secured to push rods 54b, vertically reciprocated by cams 49; movement of the member 24 both vertically and along the rods is synchronized with mould travel.

Title: Portable scintillation meter for radon or other alpha particle emitting gas
Inventor: GLAUDE VITAL MAX MARIE
IPC: G01T1/202
Filed: 1957-09-04
Abstract: 860,849. Portable scintillation counters. COMMISSARIAT A L'ENERGIE ATOMIC. Sept. 4, 1957 [Sept. 14, 1956], No. 27959/57. Class 40 (3). In portable apparatus for determining the content of an alpha particle emitting gas, e.g. radar, in an atmosphere, the detecting element of a scintillation counter forms one wall of a chamber into which a known volume of the atmosphere to be investigated may be introduced. Light pulses produced in the phosphor 1, Fig. 1, by the alpha particles are detected by the photo-multiplier 4 which receives its power supply from the transistor oscillator 5a via the step-up transformer 5b and rectifier unit 5c. The electrical pulsed output of the photomultiplier triggers the multivibrator 7 which produces output pulses of constant amplitude and duration which are recorded by a circuit including the relay 8, sealer circuit 9 and counter 6. The duration of a measurement can be controlled by the timing circuit 10b. The detecting chamber, Fig. 3, includes a detecting layer 1 which comprises a plate of methyl methacrylate covered by a thin layer of zinc sulphide, which constitutes the phosphor, which is protected by a metallic film or sheet, e.g. of aluminium or metallized plastic. The chamber is formed by the detecting layer, the bellows 19 of flexible material, e.g. Registered Trade Mark " Neoprene," and the flange 20 which in the bellows closed position fits tightly against the detecting surface. The bellows are drawn out to the operating position by the handle 22 and the atmosphere to be investigated enters the chamber so formed via the filter 24.

Title: Direct-viewing storage tube with character writing electron gun
IPC: H01J31/16
Filed: 1954-09-28
Abstract: 770,333. Cathode-ray storage tubes. HUGHES AIRCRAFT CO. Sept. 28, 1954 [Oct. 23, 1953], No. 28000/54. Class 39(1). A direct-viewing storage tube has a matrix mask provided with apertures corresponding to information characters designed to shape the writing electron beam. The matrix mask 20 is shown in Fig. 2. The writing beam is generated by electron gun 18 and is directed by deflection plates 48, 49 suitably energized from control circuits so that it passes through the desired character on the mask 20. The beam then traverses an electron lens, either magnetic or electrostatic but preferably the latter to avoid image rotation. The electrostatic lens comprises electrodes 59, 60, 61 so designed that the matrix is in focus on the storage screen 12 and the beam cross-overs are at the centres of deflection of further deflecting means 26 which direct the beam to the appropriate part of the storage screen 12. The latter comprises a contrast control grid 110 in a frame 116 and covered with storage dielectric material 114 e.g. talc which has a high specific resistance. A collector grid 112 has adjacent the surface 114 with its mesh wires at an angle to the grid wires 110. Behind the storage grid are the fluorescent screen 122 and a thin transparent conducting layer 120 e.g. of stannous oxide respectively. The flooding gun 16 comprises a cathode 90, intensity grid 91 and annular electrodes 92, 93 and in conjunction with wall anodes 95, 96 it produces a broad beam of electrons over the entire area of storage screen 12. The unity beam shaped successively by the characters of matrix mask 20 lays down on the storage screen 12 a pattern of letters or a symbol. With the control grid 110 at an appropriate potential, electrons are liberated by the high speed writing beam, imparting a positive potential to the impacted surface and the flood beam liberates a further excess of electrons to increase the charge contrast. To view the image, the contrast control grid is made sufficiently negative to cause the flood electrons to be repelled except at the apertures where the charge is positive, which apertures they penetrate to be accelerated onto the viewing screen. To erase the characters on the screen the potential of the grid 112 is momentarily lowered to less than the critical potential of the storage material, clearing the storage surface to return to the potential of the flood gun cathode. Specification 758,677 is referred to.

Title: Apparatus for returning beverage from the delivery pipe of a cask or the like into the cask and simultaneously cleansing said delivery pipe
IPC: B08B9/02
Filed: 1932-10-10
Abstract: 395,547. Cleaning pipes. STEVENS, L., 54, Rue de la Montagne, Brussels.- (Assignee of Vankerkhoven, A. ; 44, Rue Emile Carpentier, Curegham, Brussels.) Oct. 10, 1932, No. 28188. Convention date, June 17, 1932. [Class 99 (ii).] The invention comprises semi-automatic hydraulic apparatus for returning to a cask the liquor in the delivery pipe and replacing the liquid by water for the purpose of cleansing the pipe. A glass cylinder A in which is mounted an elastic piston G is secured between an upper cheek-plate B with an extension B<2>, B<3> for connection to the liquor delivery nozzle R and a lower plate C formed with channels C<2>, C<3>, C<4> co-operating with passages in a valve D and with tubes M, N connected to passages B<4>, B6 in the upper plate B. The valve D has six channels arranged in two separate groups D<1>, D<3>, D<5> ; D<2>, D<4>, D<6>, Fig. 3, with interconnection between the channels of a group. With the piston in the position shown in Fig. 4, the valve is rotated anti-clockwise by the handle D<7>, and water from a source of pressure passes through C<1>, D2, D<6>, C2 forcing the piston upwards. The water expelled passes through B<6>, N to the channel C<4> and through the passages D<3>, D5 to the channel C<3> and through the vertical tube M to the passage B<4> and delivery nozzle R forcing the liquor from the delivery pipe into the cask and replacing it by water. When the piston reaches the top of the cylinder, and more water is required in the delivery pipe, the valve D is rotated clockwise. Water under pressure now passes through the channels D<4>, D<6> to the tube N and after passing through the channel B<6> forces the piston downwardly. Water below the piston is expelled through C<2> and passages D<5>, D<1> to the tube M and through the delivery nozzle R to the delivery pipe. The operator effects a number of alternations of the piston in accordance with the capacity of the delivery pipe of the cask to which the apparatus is attached-a graduated scale being attached to the apparatus to serve as a guide for this purpose.

Abstract: 669,212. Carbon paper &c., printing-surfaces. COLUMBIA RIBBON & CARBON MANUFACTURING CO., Inc. Nov. 7, 1949 [Nov. 9, 1948], No. 28425/49. Drawings to Specification. Classes 100 (ii) and 100 (iv). A transfer sheet includes a base of tissue paper or the like, a transfer coating, and a protective coating to prevent smudging and comprising a binder and an antifriction component of lamelliform particles dispersed in the binder. The transfer coating may have a wax base and comprise plasticising and hardening ingredients, together with a pigment (if for use as carbon paper), or a dye such as crystal violet (if for use as a hectograph transfer sheet), and may also be used, with or without a pigment, to transfer an ink-receptive image to a planographic sheet. The protective coating may be applied by a solvent such as carbon tetrachloride, trichlorethylene or naphtha which is ineffective against the transfer coating, and may comprise a resin soluble in one of such solvents, and an oleous or waxy ingredient to ameliorate the toughness of the resin. The anti-friction component may be aluminium, bronze or graphite powder, ground fish scales, or mica. An example of a protective coating is a binder comprising the substance known under the Registered Trade Mark " Tornerit " (chlorinated rubber) 1¢ parts and beeswax 2¢ parts, aluminium powder 1 part, carbon tetrachloride 70 parts. The coating is spread and allowed to set by evaporation of the solvent, and a buffing- wheel may be applied to polish the surface and make it more resistant to abrasion. If both the transfer and protective coatings are waxy, the overcoat may be applied in a semi-liquid state, or the waxy constituent of the overcoat may have a lower melting point than that of the transfer coating, to avoid co-mingling of the coatings. The protective coating may have an added layer of wax on top of the composite layer described, and is preferably applied so as to overlap the edges of the transfer coating. Printing-surfaces.-Master units may be constructed by attaching a master sheet along one edge to a hectographic transfer sheet as described. Pre-printed inscriptions may be applied to the master sheet by passing the unit through a printing machine, no slip sheet being necessary. A similar unit for preparing a directreading design on a sheet for use in offset planographic printing may be formed by attaching a transfer sheet, whose under-surface consists in part of transferable ink-retaining material, to a sheet having an upper planographic surface, and writing, typing, &c. on the uncoated surface of the transfer. If a mirror-script design is required for non-offset printing, writing, typing, &c. the inscription is effected on the under-surface of the planographic sheet.
