Title: Improvements in electrical water heaters
IPC: F24H1/20
Filed: 1925-12-01
Abstract: 244,743. Steere, E. C. Dec. 16, 1924, [Convention date]. Heating by electricity.-In heating water in an iron or other vessel or for continuous or intermittent supply, the heating element is suspended within an electrically insulating casing arranged within a water container so that there is a high electrical resistance through the water between the element and the inlet and outlet ports of the container. The heater 19, Fig. 1, may be arranged within a porcelain casing 20 having openend pipes 21, 22 on each side of the heater for the flow of water, the casing 20 being secured by stirrups 23 to the water container 10. The container 10 has inlet and delivery pipes 16, 12 and a removable cover 11. The casing 20 is closed by a detachable insulating lid 18 carrying the heater 19 and its leads 28 and held in position by an offset bar and a central locking bolt 30, the bar engaging at its ends under side bars 34 and the bolt 30 passing through the bar and engaging a metal washer in the lid 18. The leads 29 pass through an apertured cover 31 secured by bolts 32. Rubber or like water-tight gaskets 15, 24, 27 are provided in the joints between the container 10, the cover 11, the casing 20 and the lid 18. In a modification, Fig. 4, the casing 20 has inlet and outlet ports 35, 36 and is suspended in the water container 38 by a flange 37. The container 38 has a supply pipe 40 from a cistern 41 and delivery and return ports 42, 44. The lid of the casing may be locked in position by inserting an electric plug on the leads and a central opening may be provided in the cover of the container to permit mounting of the electric plug. The casing may be suspended by stirrups from the cover of the container.

Title: Coin freed post-card vending machine
IPC: G07F11/02
Filed: 1949-11-26
Abstract: 677,151. Coin-freed machines for vending articles from piles. BEAN, G. L. Nov. 26, 1949, No. 30339/49. Class 27 Storage details. Delivering articles from piles.-Post-cards to be delivered singly from a stack in a coin-freed machine are each mounted on a corrugated paper base to provide support and make the cards of a convenient thickness. The bottom card, together with its cardboard mount, is delivered from a stack 18, shown in plan in Fig. 1, by a sliding pusher 13 when a handle 9 projecting through a slot 20 in the casing of the machine is turned about its pivot on a bracket 10 after being released by the insertion of a coin. Coin action, weight.-The handle 9 is normally locked by the engagement in a hole 12 in the handle of a pin 11 on a coin balance 5. A coin delivered by a shoot 19 turns the balance 5 about its hinge 7 until it rests on an arm 15, carried by the handle 9, with the pin 11 raised from the hole 12. When the handle 9 is moved to deliver a post-card the movement of the rod 15 permits the coin balance to tip further to deliver the coin to a cash box (not shown). The centre of gravity of the balance is so placed that it rests against a stop in the coin discharging position until restored to its normal locking position by the arm 15 as the handle 9 is returned by a spring 17.

Title: Improvements in or relating to television receivers
IPC: H04N5/44
Filed: 1955-10-27
Abstract: 817,267. Automatic gain and. selectivity control. COLE Ltd., E. K., and PICHAL, H. T. Oct. 29, 1956 [Oct. 27, 1955], No. 30702/55. Class 40 (5). In a television receiver, the cathode circuit of an I.F. stage is arranged so that the bandwidth is reduced for weak signals by the action of the A.G.C. voltage on the input capacitance. As shown; the mixer output M is coupled to the first I.F. stage by two coils L1, L2 and capacitance C1, Cgk. The coils L1, L2 are adjusted to resonate at frequencies respectively near the lower and upper limits of the I.F. bandwidth whilst the grid is biased back by a strong A.G.C. voltage. On reception of a weak signal the reduction in. A.G.C. voltage causes the input capacitance to increase, thus shifting the resonance peak due to L2 towards that due to L1. The cathode capacitor C2 is selected to provide the required narrow bandwidth with zero A.G.C. voltage.

Abstract: 407,770. Automatic-feed weighers. SOUTHALL & SMITH, Ltd., Villa Street Works, Hockley, SOUTHALL, C., 48, Sir Harry's Road, Edgbaston, both in Birmingham, and FREARS, J. N., 56, Westfield Road, Leicester. Nov. 3, 1932, No. 30936. [Class 143.] In an automatic weighing machine for dough or other plastic material, small pieces of the dough &c. are severed in succession from the mass until the requisite weight is made up and means are provided for automatically controlling the feeding and cutting mechanism from the weighing apparatus. Apiece of dough of less than the desired weight is placed on the scale pan b during an interval when the beam a is locked by a cam y on a one - revolution shaft x. During the rotation of the shaft the beam is unlocked and a striker 7 rocks a clutchoperating shaft p to start the dough-extruding screw and rotary knife i, the shaft then coming to rest. The knife cuts off small pieces of dough in rapid succession until the correct weight has fallen into the pan whereupon the beam opens a switch j in the circuit of an electromagnet k which releases a driving clutch m and stops the dough-extruding screw and the knife. The movement of the clutch closes a further switch to couple-up a one-revolution clutch w and re-start the shaft x. A cam 2 on the shaft x displaces a catch 5 allowing the loaded pan to rotate and discharge its contents, at the same time bringing a second pan into filling position. The shaft x then again locks the beam for an interval prior to a repetition of the weighing operation. Scale pang.-The scale pans are made of wire gauze or closely perforated metal sheet to minimize adhesion between the dough and the pan.

Abstract: 286,018. Newton, E. P. Dec. 7. 1926. Indicating number of vacant seats; illuminated stencil and transparency indicators.-Relates to a system for indicating the number of the vacant seats in a row of seats in a theatre upon an indicator located at the end of the row and the total number of vacant seats on an ammeter located in the box office. As shown in Fig. 1, lamps b in a casing c<1> at the end of a row of seats are connected to seat-operated switches a which are closed when the corresponding seats are vacant to prepare the lamp circuit. The lamps are connected in parallel to a common return wire including a switch d which when operated causes illumination of the lamps associated with the vacant seats. An ammeter i located in the box office mav be selectively connected by switches h in series with the row indicators to register the total number of vacant seats in the rows and a second ammeter is employed to indicate the vacant seats in a number of rows. Indicators mav be located at each end of a row of seats, and may be connected in parallel or be independently controlled-by the seat contacts. Fig. 3 shows an indicator for use at the end of a row. The lamps b are arranged behind a screen k bearing a series of numbers or letters corresponding to the seats. The switch d for operating the lamps is mounted on the front of the casing and a projecting portion j<2> of the casing has illuminated screens j<3> bearing the number or letters of the row. The portion j<2> also is adapted to illuminate the gangway. In a modification a special aperture is provided in the casing for illuminating the gangway. In a further modification, the indicating lamps are replaced by electromagnetically operated flaps adapted normally to cover signal apertures, in a casing.
