Title: Improvements in thermally-actuated electric switches
IPC: H01H71/20
Filed: 1924-03-27
Abstract: 220,584. Svensson, I. V. March 27, 1924. Electrically - released switches. - In a thermally-actuated switch, of the kind having contacts normally engaging one another and at least one of which is adapted to become released and be movable at a certain temperature so that they will be disengaged by spring action or the like, the contact adapted to be released is so arranged that, when released, it is moved aside by the other contact, which owing to spring action, moves out of engagement. The invention, as applied to a sad-iron, comprises an insulating body 21 having holes in which sleeves 22, 23, which form the supply terminals, are fitted, that 22 communicating with a lead 26. The sleeve 23 is secured by a screw to a strip from which projects a stud 30 surrounded by a contact spring 31, one leg 32 of which bears on a flange 33 of the strip, while the other 34 bears on a contact 35, mounted on a stud 36 projecting from a plate 37 which is connected by means of a screw 38 and bar 39 to a lead 40. The contact 35 is controlled by a spiral spring 41 urging it against a stop 42 formed as a flange or plate 37, and is secured bv fusible solder to stud 36 or to stop 42 or by friction around the stud 36. When the solder melts or the contact 35 expands sufficiently around the stud, the contact 35 becomes loose, so that the spring 31 will overcome the spring 41 to move aside the contact 35 and so break circuit, the spring 41 then restoring the contact 35 which is again secured when the device cools off. A re-setting button 44 urges the contact 34 until it snaps behind the contact 35. The spring 31 is bent around the stud 30 so that when under tension it will grip the stud and make firm contact, and the leg 32 will also be pressed against the flange 33 to reinforce the contact.

Title: Improvements in or connected with Automatic Feeding Water Heaters or Boilers, more particularly of the Type used for Supplying Small Quantities of Hot Water.
IPC: A47J27/21
Filed: 1918-05-14
Abstract: 129,750. Richmond Gas Stove & Meter Co., and St. Leger, A. May 14, 1918. Heating water.-Relates to waber-heaters of the type comprising inner and outer shells 1, 3, Fig. 1, connected at their bases by means of outwardly-directed flanges 5, 6 so as to be readily separable, the lower portions 2, 4 of each shell being of larger diameter than the upper portions 1, 3. According to the invention, an annular weir or sleeve 19, of a diameter slightly larger than that of the portion 1 of the inner shell, is located about the height of the water-level WL, over which the water boils into a closed space above and can be drawn off by a tap 18. The weir 19 is supported by a diaphragm 16 connected to the outer shell, and a pipe 20 located between the two shells returns surplus water from above the diaphragm to the lower or heating portion of the boiler. A cam-shaped member 22, Fig. 3, is mounted on the tap handle 21, so that, when the tap is turned on, the cam engages a spherical head 23 at the top of a valve-rod 25 and increases the supply of gas through the pipe 8 to the burners, thus causing the water to boil rapidly over the weir 19. An auxiliary sliding member 22<x> may also engage the spherical head 23 in the closed position of the tap, so that the gas supply can be increased until the water is at boiling- point; then the gas supply can be reduced, until water is drawn off at the tap 18. A dome-shaped member 9 may be arranged over the burners to deflect the gas into contact with the inner shell 2, and a perforated sleeve 10 may be fixed at the upper part of the shell 3 to allow escape of steam without allowing water to escape. The waterlevel may be maintained automatically by a supply reservoir fitted with a valve, and other hotwater receptacles may be connected with the water-heater, such as receptacles having a container for making beverages supported in the main receptacle.

Abstract: 371,552. Wireless signalling. WALLACE, M., 98, St. Mark's Place, St. George, Staten Island, New York, U.S.A. March 18, 1931, No. 8334. Convention date, May 6, 1930. [Class 40 (v).] In order to facilitate aerial or marine navigation, an extensive land or sea area is covered with intersecting channels of beam radiation. For instance, a primary division into zones 500 miles wide from east to west is followed by subdivision into 25 20-mile channels, each provided with a sharplydirective beam or loop transmitter. The transmissions in each channel 1 .. 4 are distinguished by a step-by-step progression in frequency, which may be varied from a minimum to a maximum, next to a minimum, and then be repeated, so as to economize the total frequency-band allotted to the system. Or the modulation characteristics may serve to distinguish the different channels. A similar series of channels are provided running north and south, so that the whole area is covered by a criss-cross series of beams. In order to prevent excessive spread and overlapping, the primary transmissions may be relayed by a second set of transmitters 1a .. 4a as shown.

Title: Ingot moulds
IPC: B22D7/06
Filed: 1973-02-20
Abstract: 1449052 Cast iron moulds; heat treatment BRITISH STEEL CORP 20 Feb 1974 [20 Feb 1973] 8367/73 Headings C7A and C7N [Also in Division B3]  A cast iron ingot mould 1 incorporates graphite in a matrix which has a predominantly pearlitic structure in the region 10 surrounding the cavity 5 and a predominantly ferritic structure surrounding the region 10. The ferritic region may be at least three times as thick as the pearlitic region 10 and contain up to 40% by volume of pearlite. The region 10 may contain up to 40% by volume of ferrite. To promote the formation of vermicular or spheroidal graphite, Mg, Ce or Ti or a combination of some of these elements or soluble nitrogen may be included in the molten iron for casting the mould. As shown, a mould 1, covered by a square iron slab and standing on an annular iron slab 3 in an electric furnace 2, is heated above the A 1  temperature to anneal the outer region to ferrite while cold air passes from a pipe 7 through the cavity 5 to outlets 8, 9. The cast iron has the following constituents; - C 3À75, Si 1.50, Mn 0.75, Mg 0.013, P 0.030, Ce 0À006 and S 0.015 and, initially, the matrix contained 85% pearlite, the remainder being ferrite, while the graphite was 85% of vermicular form. After heating for 20 hours, the outer ferrite region is three times as thick as the region 10. The mould 1 then cools for 12 hours before removal from the furnace 2. In an alternative method, the same metal is cast in a sand mould and the resulting ingot mould is allowed to cool to 850C, 150C above the A 1  temperature, so that the matrix is 80% ferrite. The sand in the cavity is then removed to allow the region 10 to cool more rapidly. After the outer surface is below the A 1  temperature, the ingot mould is removed from the sand mould and allowed to cool. The outer, ferrite region is found to be four times as thick as the region 10. Cast iron chills may be used in the mould cavity, after the sand removal, to give a thicker pearlitic region 10.

Title: Improvements in or relating to machines for the packing of bottles or like articles into cases or the like
IPC: B65B21/18
Filed: 1958-03-15
Abstract: 850,546. Packing bottles &c. BERRY, R. M. March 16, 1959 [March 15, 1958], No. 8379/58. Class 94(1). In order to avoid damage by a misaligned partition, to bottles &c. being lowered into crates, the speed of descent of the bottle gripper head is automatically reduced as the bottles approach partitions top level. The invention is described in connection with the machine set out in Specification 758,360 in which the weight of the gripper head is counterbalanced by a vertically slidable weight. The weight 5, in the present invention, forms part of a piston sliding in a cylinder 6 having an extension of narrower bore 15 leading to an air outlet 7. Adjustably mounted on the piston rod is a secondary piston 13 which, when the speed of descent is to be reduced, enters the extension 15 so that air can now escape only through a controlled outlet 16.

Title: Circuit for detecting the occurrence of peaks in an input signal waveform
IPC: G01R19/04
Filed: 1961-03-08
Abstract: 920,304. Transistor pulse circuits. NATIONAL CASH REGISTER CO. March 8, 1961 [March 9, 1960], No. 8411/61. Class 40 (6). [Also in Group XXXVI] A circuit for deriving a rectangular output waveform having either leading or trailing edges whose timing corresponds with the peaks of an input waveform comprises a differentiating circuit to which the input signal is applied followed by an amplifier provided with negative feed-back the extent of which increases with the signal applied thereto followed by a limiting circuit from which the rectangular output waveform is derived. In the circuit illustrated the differentiating circuit 27, 28 is preceded by a transistor 20, biased by potential divider 18, 19, 24 to be normally cut off, so that only the positive peaks of the input waveform 47 are transmitted to the differentiating circuit, thus eliminating low-level spurious signals. The differentiated signal is amplified by transistors 30 and 40, the output from which is applied as negative feed-back to the emitter of transistor 30 via emitter-follower transistor 50. In order that the amount of feed-back may increase with signal amplitude so as to prevent limiting in the amplifier for large-amplitude signals, the feedback is applied through the diodes 54-57. In addition, D.C. feed-back is provided from the collector of transistor 40 through resistors 44, 45 to reduce the temperature-sensitivity of the circuit. The emitter-bias potential for transistor 40 and collector-bias potential for transistor 50 are both derived from a circuit including Zener diode 79. The amplified differentiated signal 70 is then applied to transistor 60 which is biased just past cut-off by means of diode 37 connected between the base and emitter electrodes. Transistor 60 is hence rendered conducting as the signal 70 makes the transition from positive-going to negative-going thus resulting in a positive-going edge in the output circuit corresponding with the said transitions in polarity of the differentiated signal and so with the positive peaks of the input signal. The signal amplitude at the output is restricted by means of a clamping diode 71.
