Abstract: 389,935. Feeding-devices. UNDERFEED STOKER CO., Ltd. and MOUNT, H. C., Aldwych House, Aldwych, London. Dec. 29, 1931, No. 35905. [Class 59.] A method of feeding material composed of pieces of different size to ensure that it is uniformly distributed consists in supplying the material to the upper end of an inclined plate of triangular shape having one edge inclined convergently to the direction of travel of the material along the plate and forming a distributing edge over which the material falls into a series of shoots during its progress along the plate. Figs. 2 and 3 show the method applied to a mechanical stoker. Fuel passes from a bunker 1 into a spout 2 from which it falls on to the upper edge 10 of two triangular inclined plates 3 each having a distributing edge 11 associated with which are shoots formed by partition plates 5 and front and back plates 8, 8<1>, discharging into the hopper 6 of a mechanical stoker. The apparatus may be duplicated, the two parts being placed back to back with a common inlet and the edges 10 in alignment.

[Classes 29 and 64 (ii)] In heat insulation for refrigerator cabinets as claimed in the parent Specification, a controlled flow of air is provided through the air-layer insulation from inside to outside by providing openings in all the containers including the outer one. The inner chamber communicates with the atmosphere by a passage 6, Fig. 2, and the openings in the other containers are alternately at the highest and lowest points. The air flow is outward through the insulation so that the air becomes warmer and moisture is not deposited in the insulation. In Fig. 3, the containers 8 are of corrugated cardboard between plane cardboard sheets secured to a wooden frame 9. The faces of these walls are coated with bright reflecting metal foil. An evaporator is introduced through an opening which is closed by a cork disc 12 having an opening 13 corresponding to the opening 6, Fig. 2. The outer wall 7 of the cabinet is not made air-tight. The door, Fig. 4, is constructed of doublewalled corrugated cardboard 14, the air spaces being made air-tight by strips 15, 16..A frame 18 of insulating material is provided with rubber packing 19, 20.

Abstract: The teeth (12b) of the comb are formed by the coils of a helically wound wire, in each case one group (1) of teeth within a housing (6c) being held together in the pushed-together state by a respective cap (3). Using an advancing member (74), which is constructed in the form of a wire coil, the turns of which engage in the upper parts of the groups (1) of teeth, said groups (1) of teeth can be slid out of the housing (6c). By rotating a knob (78), the group (1) of teeth in which the free end (77) of the advancing member (74) engages, is moved forwards and, as a result, in this way new groups (1) of teeth can be subsequently supplied as soon as the group being used has been soiled and removed. The caps (3) protect the teeth against mutual displacement and hooking together and against soiling. The production of the group of teeth is simple, the use of the comb is hygienic and easy as soiled groups of teeth can be removed and the shape of the teeth is agreeable for the user. <IMAGE>

Filed: 1975-09-09
Abstract: 1519829 Automatic current control GENERAL ELECTRIC CO 9 Sept 1975 [26 Sept 1974] 37016/75 Heading G3R A regulated current supply circuit includes a rectifier delivering current with periodic fluctuations which cause a pulse generator to reset an integrating sawtooth wave generator. The rectifier output current is fed to a load through a current control device and a current sensor, the device being controlled by a comparator which receives inputs derived from the sawtooth generator and from a further comparator responsive to the current sensor. As shown, a battery 12 receives charging current from an A.C. supply 10, 11 by way of a transformer T1, full wave rectifier D1, D2, thyristor CCD, current sensing resistor R1, and inductor L1. The sensed current pulses are averaged by an integrating operational amplifier to OA4 to produce a signal which is compared in amplifier OA5 with a reference signal derived from a Zener diode ZD. The resulting error signal is supplied to a comparator amplifier OA3 which also receives a sawtooth voltage from a linear integrating amplifier OA2. The integrator is reset to zero at the end of each half-wave of the supply voltage by pulses from an amplifier OA1 receiving the rectified sine wave output from rectifiers D1, D2 and the references voltage from the Zener diode ZD. The amplifier OA3 controls the firing angle of the thyristor CCD, so that the current is regulated to a value set by a potentiometer P1. A switch S1 is opened to terminate battery charging when the temperature or voltage of the battery reaches a predetermined value.
