Abstract: 1,225,121. Counting apparatus. ENGLISH NUMBERING MACHINES Ltd. 5 July, 1968 [20 July, 1967], No. 33377/67. Heading G4D. In a device for producing a check digit or symbol comprising a check digit wheel 1 having check digit carrying print faces 2, a pawl tooth 5b of a comb pawl 5 (Fig. 6) steps a ratchet la driving the check digit wheel, and a pawl tooth 5a of the comb pawl steps a ratchet 6a driving a control wheel 6, the comb pawl being prevented from stepping the check digit wheel through one step when the wheel 6 passes through a predetermined position. The tooth 5a is longer than the tooth 5b, and the ratchet 6a driving the control wheel has a land 7 of reduced depth, so that when the longer tooth 5a engages the shallow land 7 (Fig. 2), the shorter tooth 5b is held clear of the ratchet 1a and is unable to rotate the check digit wheel 1 (Fig. 3). Rotation of the control wheel 6 steps the unit wheel of a numbering box. The check digit wheel moves in step with the unit wheel, except at a decade change on the numbering box, which corresponds with the engagement of the longer tooth 5a with the shallow land 7, when the same check digit is displayed for two consecutive numbers. Check digit wheels having 13, 11, 10 or 7 digit carrying print faces for moduli 13, 11, 10 or 7 are described.

Abstract: 1,226,661. Rotary hydraulic motors. GRESEN MFG. CO. May 1, 1968, No.20674/68. Heading F1F. A rotary hydraulic motor of the orbital internally-meshing gear type, comprises a twopart housing 10, 11, Fig.1, having sandwiched therebetween a parting plate 13 and a chamber forming member 12 encircling an orbital member 45, and a rotor 27. The orbital member is formed with seven internal lobes 46, Fig.2, in meshing engagement with six external lobes L1.... L6 on the rotor and with a ring of external teeth 47 in meshing engagement with an equal number of internal teeth 49 on the chamber forming member 12. The tooth spacing and the radial distance between the teeth 47 and the teeth 49 is such to permit orbital motion of the member 45 without it rotating about the rotor axis. The rotor 27 secured centrally on an output shaft 21 is rotated in either direction depending on which of two ports (36), (37), Fig.3 3 (not shown) is an inlet and which an outlet. The port 36 is connected to the increasing-decreasing volume spaces between the lobes through an annular groove 33 in the housing part 10 and porting plate 13 and rings of ports 34, 30 in the porting plate and the port 37 to these spaces through an annular groove 32 and rings of ports 35, 31 with the number of ports in each ring being equal to the number of internal lobes on the orbital member 45. As the member 45 orbits the ports 30, 31 are sequentially covered and uncovered by the member with, e.g., hydraulic pressure fluid being supplied through the ports 30 and exhausted through the ports 31. Apertures 14, 15 in the housing parts 10, 11 respectively and notches 16, 17 in the chamber forming member 12 and porting plate 13 accommodate fastening means to secure the motor in any desired position. In a modified embodiment, a further porting plate is located on the upper side of the chamber forming member to enable hydraulic fluid to be supplied to and exhausted from the lobe spaces on both sides to balance lateral forces on the rotor and orbital member to reduce friction forces.

Abstract: 1,227,208. Injection moulding footwear. T. FUKUOKA. 29 Nov., 1968, No. 56723/68. Heading B5A. [Also in Division A3] A sandal consists of a band member 1 and a sole member 2 which are integrally and simultaneously moulded from thermoplastic resin in such a way as to form a solid outer layer 4 and a foamed interior 3. The upper surface 2A of the sole 2 is shaped to conform to the wearer's foot and the upper and/or lower surface of the sole 2 is covered with a layer 5 of hard thermoplastic material. The cover layer 5 is preformed from a layer 5<SP>1</SP> which is held by holders 10 (Fig. 3) beneath heaters 7 and is then moved downwardly into contact with a vacuum forming mould 8. The edges a of the sheet are then cut off and the layer 5 is then placed in the mould used to form the sandal. Thermoplastic material together with a blowing agent is then injected into the mould at a temperature sufficient to render the material fluid and above the foaming temperature but at a pressure sufficient to restrain foaming. When the material contacts the cooled mould surface it forms the solid outer layer 4 and the mould cavity is then enlarged so that the uncooled central mass foams to form the foamed interior 3. Suitable materials for the sandal are polystyrene; polymers and copolymers of a-methyl styrene, ar-methyl styrene or vinyltoluene, mono- and di-chlorostyrene; copolymers of vinylidene chloride; polymers and copolymers of methyl methacrylate, ethyl acrylate and other derivatives of acrylic acid; polymers and copolymers of vinyl acetate and vinyl butyral; and cellulose derivatives such as cellulose nitrate or acetate. Suitable blowing agents are dichlorodifluoromethane, carbon dioxide, pentane and other low boiling hydrocarbons or heat sensitive gas generating agents. In a modification (not shown) a lower sole member having an integral band and hard cover layer on the tread surface is combined with an upper sole member having a hard cover layer on its upper surface to form the completed sandal.

Abstract: 1,228,017. Embossing; etching. ALUMET MFG. CORP. 24 July, 1968 [31 Aug., 1967], No. 35353/68. Heading B6J. [Also in Division B3] A method of blanking thin sheet metal, i.e. 0À003 to 0À06 inch thick, comprises partly punching through the thickness of the sheet metal stock and then treating the still-attached part 46 and the stock 12 with an etch-erosion liquid to substantially reduce the engagement between the stock and the part. The stock may be brass, copper, nickel, aluminium, zinc, magnesium, cold-rolled steel, zinc- or tin-plated steel or steel or precious metal alloys. Preferably an etch-resist coating is applied to both faces of the part before the etch-erosion step. Suggested coatings are pitch, asphalt, wax, nitrocellulose, dissolved in acetone or toluene, and epoxy resin. A coating 34, 36 may be applied to both faces of the stock before punching or to the upper face of the stock before punching and to the lower face only of the part after punching. If the thickness of the part to be blanked is not critical or the stock is at least 0À015 inch thick, the resist coating can be omitted. A setting station including e.g. cooling air streams or heaters precedes the punching station which may comprise rollers, carrying a plurality of complementary punch and die parts, or a punch press. The die 44 includes passages 60 through which air under pressure is intermittently introduced to strip the part 46 from the die. The etch erosion liquid is applied by conventional means, e.g. an immersion tank (78) (Fig. 1, not shown). Etch-erosion liquids for use with copper stock include a water solution of ferric chloride, a mixture of chromic and sulphuric acids, a mixture of ammonium bicarbonate, ammonium hydroxide and sodium chloride, a mixture of ammonium persulphate and mercuric chloride and a water solution of cupric chloride. Etch-erosion liquid for use with zinc or magnesium stock is dilute nitric acid and for use with aluminium stock a dilute water solution of sodium hydroxide and sodium carbonate with glucose. The part(s) may be freed from the stock completely during the etch-erosion step. If not, the stock with the part(s) lightly retained therein then passes under an ejector nozzle (90), which blows the part(s) down on to a conveyer (98) immersed in a liquid for neutralizing the etching liquid. The etch resist coating is subsequently removed.

Abstract: 1,250,617. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 2 June, 1969 [28 June, 1968], No.31159/68. Heading G6C. A nuclear reactor has a separative barrier between an inner moderating zone containing the nuclear fuel and an outer reflecting zone which surrounds the inner zone, the inner zone having liquid moderating material containing a variable quantity of soluble poison and the outer zone having liquid moderating material which is soluble poison free. In one embodiment, heavy water moderating material 4 is contained within a calandria vessel 1 between the flat end walls 3 of which extend a multiplicity of calandria tubes 2 (only two are shown). An internal barrier 5 extends between the end walls 3 to separate the heavy water in an inner zone 6 from that in an outer zone 7. A small amount of boric acid is dissolved in the heavy water in the inner zone 6 and the mixture is cooled by circulating it through heat exchangers (not shown) via inlet and outlet branch pipes 8, 9. The cooling circuit also includes ion exchange resin beds whereby the boric acid is progressively withdrawn as the fuel is burned up. A branch line 11 from the inlet pipe 8 feeds cooled heavy water to a space above a membrane 10 located in the vessel 1 above the heavy water 4. The heavy water flows into the inner zone 6 via clearances between the membrane 10 and the calandria tubes 2, thereby cooling the upper ends of the tubes. Two branch pipes 12 feed helium purge gas into the lower regions of the heavy water in the outer zone 7 and ducts 13 in the barrier 5 conduct this gas from the outer to the inner zone. A branch 14 conducts the gas to clean-up plant and a deuterium/oxygen recombination unit (not shown). The turbulence caused by the purge gas injected into the heavy water of the reflector enhances heat transfer through the barrier 5 to the heavy water in the inner zone 6, thus avoiding the need for an additional heat exchange circuit for the heavy water in the outer zone 7.

Abstract: 1289118 Starting discharge lamps GENERAL ELECTRIC CO Ltd 12 Oct 1970 [10 Oct 1969] 49916/69 Heading H2H A starting circuit for an electric discharge lamp comprises a voltage transformer, a charging circuit including resistance and capacitance which in use in adapted to be charged by a power supply for the lamp, and a discharge circuit responsive to the voltage developed across the capacitance to discharge same into the primary of the transformer when that voltage attains a predetermined value. In the embodiment shown, a lamp and an A.C. or D.C. supply is in use placed across terminals 2, 3, and in operation, capacitor C 1  is charged via a diode D 1  until the reverse potential across Z 1  is sufficient to cause breakdown and trigger SCR 1  causing C 1  to discharge into the primary of the transformer T 1 , the high voltage pulse generated in the secondary being sufficient to start the lamp. The time constant of the R-C circuit is preferably greater than the frequency of the supply e.g. 1 second. In the event of the lamp failing to ignite, a protective system is incorporated, the resistor R 2  being a thermistor and arranged to be thermally connected to R 1 , whereby, after operation of the circuit for a particular time preferably in the range 1-5 minutes, the resistance of R 2  will fall to a value whereby the breakdown voltage of Z 1  across C 1  is not attached. In a modification, Fig. 5 (not shown), such protective features are provided by a second capacitor (C 3 ) in parallel with a resistance (R 10 ) of the potential divider, the capacitor being in the emitter-base circuit of a normally non-conducting transistor (X 1 ) and in parallel with a further Zener diode (Z 3 ) connected to the emitter. In use, in the event of lamp failure, the capacitor (C 3 ) is charged to the reverse breakdown voltage of the diode (Z 3 ) to render the transistor (X 1 ) conducting to allow discharge of the capacitor C 1  through collector resistance (R 12 ). Several alternative embodiments are mentioned: the diode Z 1  may be replaced by a resistance arrangement or other breakdown diode: the rectifier SCR 1  may be replaced by a two terminal breakdown device.
