Title: Improvements relating to machines for washing clothes
IPC: D06F17/00
Filed: 1946-11-06
Abstract: 618.636. Washing machines. WALKER, A. E. Nov. 6, 1946, No. 32999. [Class 138 (ii)] A machine for use in washing or cleaning clothes comprises a shell 1 of substantially uniform rectangular cross-section which is mounted to rock about a horizontal axis in trunnions 8, 38 fixed to opposite sides of the shell substantially midway between the ends thereof, and a rectangular door 2 hinged at one end of the shell about an axis parallel to the axis of rocking; this arrangement permits the shell to be rocked into a substantially vertical position with the door at the top for charging and into a substantially horizontal position for discharging. The trunnions 8, 38, which are mounted on standards 7, are hollow so as to serve as inlet and outlet connections for the cleaning fluid through pipes 12, 13, 14. The inner end of one trunnion 8 is connected to a closed funnel-shaped channel 17 which ends at the top of the shell in a perforated baffle plate 18. When the machine is used in the vertical position, the shell is first filled with water through the trunnion 38, and water is then admitted through an inlet 15 in the bottom of the shell so as to set up a flow through the shell, plate 18 and channel 17 for discharge through the trunnion 8. By inverting the containers and admitting compressed air through an inlet in the bottom of the shell, the water is discharged through the channel 17 and trunnion 8. Steam for heating and compressed air for agitating the water may also be admitted through the bottom of the shell. If desired, washing may be effected by continuously rocking the container through a small angle to opposite sides of its horizontal position, as shown in Fig. 3, by means of an electric motor 19 which drives a wheel 20 having an eccentrically mounted link 21 pivotally connected to one corner of the machine. Spring buffers 25 are provided for limiting the rocking movement. To permit the container to be swung to the vertical position, the buffers 25 are movably mounted and the link 21 is detachable.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/42
Filed: 1925-09-09
Abstract: 266,266. Automatic Telephone manufacturing Co., Ltd., (Automatic Electric Co.). Sept. 9, 1925. Selective signalling apparatus.- In response to a code signal consisting of one, two or three units of a series +-+-, a group of four relays is energized in different combinations by a polarized relay the contacts of which are differently connected to the group of relays at different stages of the signal by means of two auxiliary relays. The invention is described in its application to a registercontroller of an automatic telephone system, code signals representing the routing-number of a wanted exchange being transmitted digit by digit from a code drum 301, Fig. 4, to a. relay group, Fig. 3, and recorded on a set of relays A - - D, Fig. 5, to control a numerical sending switch SS, Fig. 3. the circuits are the same as in Specification 263,909, [Class 40 (iv), Telephones &c.]. The transmission of each digit takes place as follows. The office-register OR having been set, say, to the terminals 331 - - 334, the switch S being in its 3rd position, and relay 240 energized, when the drum 301 next passes its zero position a pickup circuit 216 energizes relay 232, Fig. 3, which locks up in series with relay 238. The first wiper 339 of the office register is now connected over circuit 355, 127, 209 to a polarized relay 235, the other terminal of which is connected to a half-battery potential, so that this relay is thrown from its neutral position in one or other direction, to close one of the contacts 272 when the drum 301 connects battery or ground to the wiper 339. It will be seen that the drum is capable of sending a series of 4 impulses +-+-, which correspond individually to the four relays A - - D, Fig. 5, but actually, according to which of the brushes 305 - - 320 has been selected by the wiper 339, only one, two or three impulses of this series are sent and a corresponding combination of the relays A - - D is energized. In position A+ of the drum 301 ground on the circuit 355 causes the polarized relay 235 to energize relay A over circuit 210, but in positions B- and C+ a circuit 214 is closed to energize relays 233, so that in position C+ ground on circuit 355 results in the energization of relay C over circuit 212. Similarly, battery on circuit 355 energizes relay B in position B - but relay D in position D-, because relay 234 is energized over circuit 215 in position C+ and D -. The relavs A - - D lock over their left-hand windings. Succeeding digits are similarly transmitted by code currents over the wipers 340, 341 and 342 of the office register. The use of a, pickup relay is not essential, as the transmission of a digit might commence from any point in the rotation of the drum 301.

Abstract: 895,329. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Oct. 23, 1958 [Oct. 23, 1957], No. 33087/57. Addition to 856,053. Class 103 (1). In a vigilance control apparatus for automotive rail vehicles as described in the parent Specification the pressure switches controlling the changeover from charging to discharging of the timing reservoir, the operation of the warning device, and brake application, are combined into a single switch in the present Specification. For initial charging, master switches MK are closed to energize relay 9 to close contacts 11, push-button 8 being then pressed to energize a relay 3 via contacts 11 to close contacts 12, the relay 9 being slowly released to open contacts 11 only after contacts 12 are closed. The contacts A of the combined pressure-switch 4 are closed and on closing of contacts 12 a valve 2 is energized to charge reservoir 1 from pressure-line 14. As the pressure increases in reservoir 1, contacts C are closed to energize a relay 6 to energize electro-vacuum valve 7 to evacuate the vacuum braking apparatus and train pipe 15, the contacts B and C close momentarily to operate alarm bell 13, and contacts A are then opened, causing contacts 12 to open to de-energize valve 2 to open reservoir 1 to atmosphere via choke 10. The pressure falls at a predetermined rate, causing at a certain pressure the closure of contacts B and C to operate bell 13 and if pushbutton 8 is not pressed to recharge reservoir 1 as above, the pressure continues to fall until contacts C are opened to de-energize relay 6 which in turn de-energizes valve 7 to cause automatic brake application, the opening of contacts C also stopping bell 13. The emergency valves 7 on other vehicles are operated through jumper connection 16. The brakes may be compressed air or vacuum brakes.

Title: Method of and apparatus for controlling flow of batch in a furnace
IPC: C03B3/00
Filed: 1972-07-17
Abstract: 1364187 Melting glass batch material JOHNS-MANVILLE CORP 17 July 1972 [19 July 1971] 33311/72 Heading C1M Glass batch material is fed to the melting section 10 of a furnace and melted therein, the respective temperatures of side regions of the melting chamber being determined by sensors. 34, 36 in side walls 12, 14, and the feed of batch material is controlled in response to the signals from the sensors so that a net flow of batch material is achieved in the chamber which swings from side to side of the chamber, the flow being diverted in response to the signals to that side of the chamber having the higher temperature. The batch material may be supplied to the melting chamber from two feeders 22, 24, in which motor-driven conveyers 26, 28 may be varied in speed to alter the feed rate from each feeder. Thus a higher speed of drive in feeder 22 than in 24 gives a net flow of batch towards wall 14 (Fig. 1), until a higher temperature is sensed at 34, as a result of greater heat absorbence of the batch on the other side (14) of the chamber. The control means (Fig. 4, not shown) reduce the feed rate of 22 and increase that of 24 until the net flow is towards side 12 (Fig. 3), and the net feed swings back and forth across the chamber in response to the sequence of signals from 34, 36.

Abstract: 1,122,491. Making nails and rivets. DORE DEVELOPMENT CO. Inc. 12 Aug., 1965 [15 Aug., 1964], No. 33427/64. Heading B3H. In the manufacture of nails, rivets and like headed articles N, Fig. 6, wherein wire stock is first cut into a length by co-operating cutting tools 42 and the cut length is then gripped by co-operating gripping tools 46 and headed, the tools are actuated by a reciprocating member (60), Fig. 4 (not shown), through toggle linkages (48), (50) which move the gripping tools more slowly than the cutting tools. This ensures that the gripping phase is more prolonged than the cutting phase. Wire stock (18) is drawn through a straightener (12), Fig. 1 (not shown), by a reciprocating gripper feed device (14) of the kind described in Specification 984,608. The stock passes into a quill (82), Fig. 3 (not shown), and through a centring guide (76), Fig. 4 (not shown). Tools 42 on holders 40 are then moved inwardly by toggle links 48 connected to the vertically reciprocating member (60) by pins 64, to cut-off and point a nail length. This is then held by the gripping tools 46 on holders 44 driven by toggle links 50 connected to the reciprocating member 60 by pins 66. Toggle links 50 are longer than the links 48 so as to provide a slower movement and hence a longer gripping period for the gripping tools 46. The nail length is then headed by an adjustable heading tool (94) driven from the reciprocating member (60) by bell-crank lever (100), Fig. 1 (not shown), and during the subsequent upstroke of the member 60, a pivoted ejector (110), Fig. 3 (not shown), discharges the nail into a shoot (120), Fig. 1 (not shown). Reciprocating member (60) slides in vertical guides (55), Fig. 2 (not shown), and is driven by an eccentric or crank, hydraulic or pneumatic means or a solenoid. The machine is similar to that described in Specification 715,433.

Title: Synthesis of hydrocarbons
IPC: C07C1/02
Filed: 1948-12-31
Abstract: In the synthesis of liquid and gaseous hydrocarbons from carbon oxides and hydrogen, the gas-liquid distribution in the products is adjusted to a desired ratio by adjusting the ratio <FORM:0656122/IV (b)/1> where H2, H2O, CO and CO2 are the molecula proportions of hydrogen, water, carbon monoxide and carbon dioxide in the feed gas. To increase gas production, the H2 : CO ratio may be increased, steam added or CO2 removed from the recycle gas.  To increase liquid production, CO or CO2 may be added or CO2 scrubbing of recycle gas reduced.  For iron catalysts the value of R may vary from about 0.2-0.9.  For high gas production, as for volatile gasolene for winter use, R may be about 0.65-0.85; for low gas, as for summer gasoline production, R may be 0.3-0.6.  Low promoter and high oxygen content of the catalyst are also conducive to high gas formation as is high temperature.  With fluidized iron catalysts, conditions conducive to high gas formation are: promoter content, per cent K2O on Fe, < 0.5; oxygen content, per cent O2 on Fe, >20 and <32; R >0.6 and < 1.0; temperature >650 and <800 DEG  F.  A catalyst of 20-200, preferably 30-100 microns particle size, is preferred.  Constant catalyst surface area should be maintained in the reactor to give constant conversion of the feed.  Finer catalyst at the top, formed by disintegration, may be removed as desired to maintain a desired size.  To increase the conversion, coarse catalyst may be removed from the bottom and replaced by finer catalyst.
