Title: A sand or the like operated power unit for a toy
IPC: A63H29/12
Filed: 1953-09-22
Abstract: 743,157. Gravity operated motors. LOW, A. M. Sept. 22, 1954 [Sept. 22, 1953], No. 26078/53. Class 10 [Also in Group XV] A power unit operated by the action of gravity or sand comprises a sand hopper discharging san( into one or other o: two sand receivers arran ged for movement to gether between a first stable position in which one sand receiver is positioned below the dis charge opening of the hopper and a seconc stable position in which the other sand receive] is positioned below the discharge opening on receipt of a predeterminec quantity of sand in one receiver which discharges sand in the second position so that continual oscillation of the receivers takes place. A hopper 2 in a casing 1 has a discharge opening vertically above a pivot shaft 5 on which is mounted an oscillator unit comprising two triangular side members 8; one of which carries a, T-shaped extension piece 12. The side members are connected by trays 9, 10 which are separated by a vane 13. A balance weight 15 below the trays is such that the oscillator rests in either of the stable positions defined by the engagement of the T-piece 12 with the walls of the casing 1. In each position one of the tray members 9, 10 rests beneath the discharge opening of the hopper with a slight slope to its open end. The side members 8 provide sides for the trays 9, 10, which. may have lips at their free edges. Sand falling from the hopper 2 on to the tray builds up until the oscillator is overbalanced and moves to its second position with the tray 10 below the hopper 2, the sand from the tray 9 falling to the bottom of the casing 1. Baffles 16 guide the sand back to the hopper 2 when the casing is inverted. In a modification, sand from the trays 9, 10 falls into a pivoted container 20, Fig. 5, provided with an opening 24 and a horizontal lip 23 on which the sand piles up at its angle of rest. The container 20 may be so arranged that as the hopper 2 is emptied, the container 20 is overbalanced so that lip 23 is directed vertically downwards and the sand is discharged. The discharge of sand from container 20 may operate a second power unit similar to that operated by sand from the hopper 2. The shaft 5 of the power unit is provided with rounded ends rotably supported in recesses in the casing walls. The T- piece extension 12 may carry the eyes of a toy cat in which the unit is mounted, the container 20 being connected to another part of the cat, e.g. its front paws, and the second power unit being connected to the cat's tail.

Title: Improvements in or relating to Telephone Answering Machines
Inventor: RUBENSTEIN LEONARD
IPC: H04M1/65
Filed: 1966-06-13
Abstract: 1,193,423. Telephone answering machines. L. RUBENSTEIN. 13 Sept., 1967 [13 June, 1966], No. 26228/66. Addition to 1,193,081. Heading H4K. [Also in Divisions G5 and H1] In a telephone answering machine of the type described in Specification 1,193,081 in which a number of answering announcements are recorded on a magnetic tape spaced by intervals to allow incoming messages to be recorded, with the recording and playback connections being made by a switching device coupled to the recorder take up spool, the coupling between the take up spool and the switching device is via a stepping switch driving the switching device and driven by pulses generated by contacts which are closed periodically at predetermined points in the take up spool rotation. Fig. 4, shows a drive circuit in which motor 100 is energized from supply 45 via switches 28, 30, or 43, closed during the time the answering machine is required to be in operation. Contacts 92 and 94 are bridged by conductive strips on an insulating substrate which is rotated with the tape recorder take-up spool, so as to complete the motor 100 supply circuit four times in a revolution of the take up spool. Each time contacts 92 and 94 are bridged motor 100 rotates, causing non-shorting contact 112 to make to one of the spaced contacts, e.g. 118, on disc 114 which maintains the supply to motor 100, even though the contacts 92 and 94 are no longer bridged, until the contact 112 lies between the next pair of contacts, e.g. 118 and 120, on the disc 114. The motor, as well as driving contact 112 via shaft 108, drives the tape recorder function change-over switch via shaft 91, the change-over switch being as described in the parent Specification. In an alternative arrangement, Fig. 5, bridging of the contacts 92 and 94 in response to the take up reel 3, rotation supplies current to the heater coil 164 of a thermally responsive strip 150 through normally closed contacts 160, 162. Heating of the strip causes operation of a ratchet drive device to rotate wheel 136 which is coupled to the function change-over switch shaft. Movement of the ratchet wheel opens contacts 92, 94 to allow the strip 50 to cool whereby initial conditions are restored ready for a further operation when contacts 92 and 94 are again bridged.

Abstract: 1,175,039. Luminescent materials. DAI NIPPON TORYO K.K. 30 Nov., 1966 [12 July, 1966], No. 26293/69. Divided out of 1,168,074. Heading C4S. ZnS or ZnCdS phosphor particles have a surface coating of acidic oxide of B, Al, V, Ga, Ge, As, Nb, Mo, Sn, Sb, Tn or W. The coating may be applied by mixing preferably in a liquid medium the phosphor and the oxide or a compound which on heating forms the oxide, e.g. hydroxides, carbonates, sulphides and NH 4  oxyacidates. The mixture is heated causing the oxide to melt, some of the oxide may diffuse on to the surface of the phosphor particle reacting to form an adhering intermediate layer. The particles may be coated by mixing the oxide suspended in an aqueous or non-aqueous dispersion and the particles and then drying. A hydroxide can first be deposited by adding a solution of the salt to a phosphor suspension and adjusting the pH value, then heating to convert the hydroxide to oxide. A further method is to add the oxide to a slurry comprising an aqueous phosphor suspension and PVA. An aqueous paste of Ge0 2  or Ga 2 O 3  and (Zn, Cd)S: Ag particles was heated to form an oxide coating on the particles. ZnS: Ag particles may be coated with SnO 2 . Slurries containing the coated particles were prepared using PVA and NH 4  bichromate sensitizer for photoprinting colour TV screens.

Title: Improvements in or relating to the preparation of vinylidene cyanide and 4,4-disubstituted cyclohexene intermediates
Filed: 1948-10-15
Abstract: Vinylidene cyanide is made by pyrolising 4,4-dicarbamyl-, 4,4-dicyano- or 4-cyano-4-carbamyl cyclohexene at 400-800 DEG  C. The pyrolysis is preferably effected at 550-700 DEG  C. and at reduced pressures, especially 2-50 mm.  The preparation of the intermediates is claimed.  4,4-Dicarboxy cyclohexene is reacted with a compound such as thionyl chloride to produce the 4,4-dicarbonyl chloride which with ammonia gives the 4,4-dicarbamyl cyclohexene which on dehydration, e.g. by heating, yields the dinitrile. 4-Cyano-4-carbamyl cyclohexene is made by reacting 1,3-butadiene with an alkyl ester of alpha cyano acrylic acid to form a 4-cyano-4-carbalkoxy cyclohexene which is converted to the amide by ammonia treatment.  This latter compound may be dehydrated to the 4,4-dicyano derivative.  Vinylidene cyanide is separated from other reaction products such as butadiene-1,3 and water and unreacted material by fractional distillation in vacuo, by solvent extraction, particularly with a solvent from which the cyanide may be crystallized, e.g. toluene or other aromatic hydrocarbon, crystallization taking place at -40 DEG  C., or if polymerization has taken place due to the presence of water the polymer is removed and depolymerized by heating, preferably at 170-250 DEG  C.  With other methods of separation a polymerization inhibitor should be present, e.g. phosphorus pentoxide and pentasulphide, which are preferred, and antimony pentoxide and conc. sulphuric acid in amounts of, e.g., 0.5-3.0 per cent.  In examples: (1) 4,4-dicarboxy cyclo hexene is refluxed with thionyl chloride, excess thionyl chloride removed, the residue diluted with anhydrous ether and added to ethereal ammonia, additional ammonia being passed through the mixture to ensure an excess and the solid product 4,4-dicarbamyl cyclohexene collected; (2) the product of (1) is dehydrated with phosphorus pentoxide to 4,4-dicyano cyclohexene, which in (3) is passed over a nickel-chromium wire at 650 DEG  C. and 5 mm. and vinylidene cyanide separated from the products by fractional distillation; (4) (3) is repeated, using the product of (1) at 600 DEG  C., and in (5) ethyl-alpha-cyano-acrylate is reacted in a bomb in a steam bath, or at room temperature, with butadiene-1,3 in the presence of hydroquinone as polymerization inhibitor and 4-cyano-4-carbethoxy cyclohexene isolated and reacted with ammonium hydroxide to give 4-carbamyl, 4-cyano-cyclohexene which in (6) is dehydrated with phosphorus pentoxide and tricresyl phosphate to give 4,4-dicyano cyclohexane which in (7) is passed through a brass tube at 670 DEG C. and 9 mm. to give vinylidene cyanide; (8) repeats (7) with the addition of a small quantity of phosphorus pentoxide.
