Title: Device for dispensing ice
IPC: F25C1/10
Filed: 1972-02-17
Abstract: 1426044 Ice-making A J HOBBS 7 Feb 1973 [17 Feb 1973 11 May 1972 14 July 1972] 7432/72 22170/72 and 33035/72 Heading F4H A device for dispensing ice, comprises a refrigeration unit which includes an annularshaped avaporator drum 80 formed with tapered moulds 81 extending therethrough, means for supplying liquid to be frozen into the moulds, and means for ejecting pieces of ice from at least one of the moulds. In one embodiment, the evaporator is rotatable about a vertical axis in bearings 88, 90 to bring each of the moulds a-p in turn into alignment with solenoid-operated means 82 for ejecting ice downwardly from the mould. A pressure plate 104 is mounted upon a set of springs 106 to bias the plate 104 against the lower surface 108 of the evaporator 80, thereby closing the lower openings of the moulds. The surfaces exposed to the ice are cooled with polytetrafluoroethylene. The indexing of the drum may be effected manually by pulling an operating handle. A spring 124 replaces the handle in position. Movement of the handle activates the solenoid means, such that when the handle reaches a stop position, a hammer head is driven downwardly to strike the block of ice. The ice passes through an aperture in the plate 104 into a shoot 84. As the spring 124 operates to replace the operating handle, a measured supply of liquid is pumped into an adjacent mould. Because of the difficulties in sealing the surfaces 104 and 108, in another embodiment, the moulds are inverted and a rubber diaphragm is used to block off the base of the mould. The shaped pieces of ice are then struck from below. The device may also be driven by an electric motor which may be actuated to index the evaporator by means of a push button. Refrigerant is fed to the evaporator via a stationary bush 133. The bush bore 136 communicates with a bore 138 in the rotatable shaft 86, O- ring sealing members 140 and 142 being provided. The refrigerant passes into a capillary tube 150 wound around the shaft. The tube 150 communicates with four tubes 152 for distributing the refrigerant around the drum. The refrigerant flows out of the shaft 86 via a stationary bore 158.

Title: Voltage sensing circuits
IPC: H03K5/02
Filed: 1976-02-25
Abstract: 1535237 Transistor bistable circuits TELETYPE CORP 25 Feb 1976 [5 March 1975] 07526/76 Heading H3T In a bistable sense amplifier comprising FET's Q3, Q4 a first control FET Ql fed with the signal being sensed is coupled in parallel with Q3, a second control FET Q2 fed with a reference potential is coupled in parallel with Q4, and means are provided for equalizing the potentials at the gates of the two control FET's during one period of a sensing cycle. The circuit is used as a read/write amplifier for a matrix of capacitive storage elements e.g. C M-1 , C M-2 . Before reading or writing, ° 1  is brought to - V volts turning on transistors Q5, Q6, Q7 to equalize the voltages at points A, B, C, D to - V R  which is midway between 0 and - V c  volts, this turning transistors Q1 . . . Q4 partially on to act as resistance elements. At the end of this preset period ° 1  goes to 0 volts, to turn off Q5, Q6, Q7, and the required cell is selected by energizing the appropriate Y conductor and X decoder to turn on the associated Q Y  and Q X  transistors. Reading. If a "0", (0 volts) is stored in a cell, capacitor C L  at A slowly discharges into capacitor C M  resulting in a fall in potential at A, and an increased resistance of Q1 so that the potential at C rises. The bistable Q3, Q4 thus sets into the stable state with Q4 fully conducting and Q3 turned off. That is, the "0" condition in the cell is transferred to node D, which in this state is at earth potential. Transistor Q8 is now turned on, and the cell discharged through it to node D, so that its state is restored to the true "0" state. Conversely, if a "1" is stored (voltage - V C ), then capacitor C L  charges from the cell and the potential at it rises to set the bistable in its other state with Q3 on and Q4 off. In this state node D is at - V C  volts, so that when Q8 is turned on the cell is recharged to this voltage. The value stored at D is read out by energizing read amplifier 23. Writing. After the presetting cycle write amplifier 22 is energized to set node D at required level after which transistor Q8 is turned on to transfer the voltage at node D to the selected cell. In a first modification, Fig. 3 (not shown) points C and D are connected to potential V, and points A and B to potential V R  during the preset time. In a second modification, Fig. 4 (not shown) the different potential V, at C and D is produced by a further FET (Q14) forming a "tail" for Q3, Q4, this further FET being also turned on by signal ° 1 . In a third modification, Fig. 5 (not shown) V, is made equal to the "1" level signal V C . In a modification of Fig. 4 (not shown) the tail transistor (Q14) is omitted and the signal ° 1  is applied directly to the transistors Q3, Q4, Fig 6 (not shown). In a still further modification of any of the circuits, the signal V R  is derived from a potential divider, the resistances of which may be FET's, Fig. 7 (not shown).

A hair curling device in which a tress of hair is wound for setting or permanent waving comprises a core 1, having a base with a funnel-shaped recess resting against the scalp and formed in two relatively movable parts 2, 3 which meet along a curved surface to grip the tress of hair, and a winding member 8 having a hair-engaging slot 10, and slidably and rotatably mounted on the core. The parts 2, 3, made of plastic, are connected by a hinge piece 4 of flexible plastic and a stud 6 on the part 3 engages an aperture 7 in the part 2 to keep the hair away from the hinge. The winding member has a perforated cylindrical surface 8 and a frustro-conical base 8a resting against a flange 5 on the base parts 2, 3, the inner surface of the winding member, or of the core, having spikes 9 which bear on the surface of the co-operating member to hold the parts 2, 3 together and, during winding, comb the tress of hair which may have been previously dampened with water or waving fluid, reimpregnation with reducing and neutralizing fluids being carried out on the hair while it is on the curling device. A scalp-protecting pad of plastic foam may be provided at the base of the core. In a modification the base is in two hinged parts, one of which is integral with the core and hair-engaging members, in the form of axial fins inclined to the surface, are provided in the winding member.

Title: Improvements in or relating to the manufacture of alginic products
Inventor: MERTON ROBERT RALPH
IPC: A23L29/256
Filed: 1952-03-31
Abstract: An alginate jelly is obtained by first mixing calcium alginate and a tribasic alkali metal ortho-phosphate in the presence of such an amount of water that in the resulting reaction a paste is produced consisting substantially of tricalcium phosphate, water, and a soluble alginate, and after such reaction (and drying if desired) introducing the product into an aqueous medium and gelling by means of a free acid, a sequestering salt for calcium ions, e.g. sodium metaphosphate, being added to the gelling bath. The amount of sequestering salt should be such as to be in excess of equivalence to any probable concentration of calcium ions in the bath.  The process can be used to prepare artificial fruits by introducing globules of the alginate solution into the gelling acid bath.  In an example sodium alginate containing colloidal calcium phosphate is prepared by intimately mixing wet calcium alginate with 1.2 times the theoretical amount of tri-sodium phosphate necessary to react with all the calcium present.  The mixture is then dried to a moisture content of 15 per cent, milled, and sifted.  The portion which goes through 44 mesh and remains on 100 mesh (British Standard Screen) is then mixed with sugar, boiling water is added, and a further amount of sugar and some glucose then added.  After boiling down the mixture some colouring and flavouring is added and the mixture transferred to a machine such as that described in Specification 727,475, [Group VI], and deposited in a solution of water, citric acid, and sodium metaphosphate, to yield artificial cherries suitable for use in confectionery.ALSO:Artificial fruits may be obtained by introducing globules of a solution formed from the alginate obtained by the process of the parent Specification into the gelling acid bath, a sequestering agent for calcium ions, e.g. sodium metaphosphate, being also added to the gelling bath (see Group IV(b)).
