Title: A machine or attachment or disinfecting means for the flushing arrangements of water-closets, urinals and the like
IPC: E03D9/03
Filed: 1925-03-17
Abstract: 253,975. Mitchell, D. G. E., and Pearson, M. March 17, 1925. Closets, urinals, &c., disinfecting and deodorizing.-A conduit K projects into the flush - pipe and diverts a quantity of the flushing water into a mixing chamber G, whilst the impact against a flap R, Fig. 3, on a shaft 0 causes a spoon N to overturn and discharge disinfectant into the chamber G, and the mixture passes into the flushpipe through a pipe S. The quantity of water passing through the conduit K is regulated by a screw M. The cup N obtains disinfectant from a well J, which is supplied from the container A on the bird-fountain principle. The container A has a valve C which is normally held closed by a spring F, but when the container is placed in position above the chamber G, the nut E on the valve-spindle strikes the bottom of the well J and opens the valve. The chamber G engages the flush-pipe through a member H, and is held by bands. In an alternative arrangement, Fig. 4, the flap and shaft are dispensed with, and diverted flushing water overbalances a dish 2 hanging from the axis 4 of the cup N.

Title: A signal lockout device
IPC: H04Q3/00
Filed: 1957-03-04
Abstract: 862,162. Lock-out circuits; parametrically excited resonators. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORPORATION, and TAKAHASI, H. March 4, 1957, No. 7172/57. Class 40 (4). Parametrons, described in Specification 778,883, are used in a lock-out circuit for connecting only one of a number of input terminals to one of a number of output terminals. The parametrons are arranged in loops. The symbols + and - are used to identify OR and AND gates. Loops in series.-In Fig. 6, a control pulse (a " 1 signal) circulates around the ring of parametrons 1-11 until a signal is applied to an input terminal such as 12. The AND gate 7 opens and gate 9 passes only " 0 " signals. The " 1 " signal fed back to gate 5 continues to circulate in the group 5, 6, 7 as long as a signal remains on 12. A signal " 1 " appears in the meantime on output terminal 02. If only one control pulse is injected initially into the ring 1-11, only one of the input terminals can be effective at any time. In Fig. 7, the control pulse circulates as before. If there is a signal on terminal 12 when the control pulse reaches gate 15, AND gate 17 passes a signal to the output terminal 02, AND gate 18 is closed to the control pulse and gate 10 continues to receive " 1 " pulses from the last gate 22 because of the NOT operation. While these pulses are received, AND gate 11 cannot respond to an input on I1. Until a control pulse " 1 " is received, gate 21 cannot respond to an input on 13. Loops in parallel.-In Fig. 5, AND gates S1 to S4 are scanned cyclically by control pulses from generator T. An input signal on one of the leads T1 to 14 opens the gate to the corresponding one of the output leads O1 to 04. As a gate opens, the OR gate stops the scanner T. Fig. 9 shows a generator P feeding a counter CR which applies control pulses cyclically to AND gates S1 to S4. When an input signal appears on a lead I1 to I4, the corresponding gate of S1 to SL transmits a signal to output terminal O when the gate is scanned by a control pulse. The signal is accepted in a holding circuit H which stops the counter by closing gate G1. The holding circuit can be released by a pulse on terminal R. The input is identified by the counter output on leads n1, n2.

Title: Bending of flat glass sheets
IPC: C03B23/025
Filed: 1958-03-06
Abstract: 831,398. Bending glass sheets. PITTSBURGH PLATE GLASS CO. March 6, 1958 [March 7, 1957], No. 7223/58. Class 56. In the bending of flat glass sheets to a predetermined configuration by heating on a bending mould having at least part of its shaping surface of metal and in which the mould is reused for further bending, a material is applied to the mould which is adherent to metal and non-adherent to glass in the temperature range between room temperature and the glass softening point and which serves as a lubricant between the mould surface and the tips of the glass sheets, the material being applied only once for several successive uses of the mould, thereby eliminating rubbing marks on the glass as the extremities of the glass sheet slide over the mould during the bending. The material used is either a paper-backed adhesive having a pressure sensitive adhesive on one surface applied to the mould or the mould is marked by a crayon containing metal oxide pigments in an organic wax binder. The material is applied preferably to each point of the mould which contacts the flat glass sheet.

Title: Automatic adaptive equalizer
IPC: H04L25/03
Filed: 1972-02-16
Abstract: 1347944 Adaptive transversal equalizer ROCKWELL INTERNATIONAL CORP 16 Feb 1972 [1 April 1971] 7253/72 Heading H4R Adaptive transversal equalizer includes a shift register 20 in which samples of the input signal are continuously circulated, with the oldest sample being dropped as each new sample is entered, and a multiplier 21 which receives the shift register 20 output and multiplies it by gain values circulating in a second shift register 40, the resulting values being fed to an accumulator 24 providing the output of the equalizer. From the equalizer output an estimate is derived of the received digit value Di and also the major sample value of the impulse response of the overall system, l o . The values l o  and Di are multiplied together in 45 and the result compared with the equalizer output y i  to obtain an error signal sign value which is fed to an exclusive or gate 52. The other input to the gate 52 is the corresponding input signal value x i-k  from shift register 20. The output from gate 52 is applied to adjust the appropriate gain register value in an appropriate direction. As described during initial setting up each signal from gate 52 causes the incrementing or decrementing of the gain value by 16, by placing switch 54 on point B, after setting up, each signal from gate 52 is sent direct to the adding device 41 via position A of switch 54. The main value of the input signal i.e. the x i  value may be multiplied by a fixed gain value g o  stored in control 25, the value g o  being selected so that the amplification is effected by a shift of the input binary signal x i  The values of l o , the main sample of the overall system pulse response, and Di, the receivers estimate of the i'th transmitted digit value can be derived by the arrangement of Fig. 2, where the multiplier 45 and comparator 46 of Fig. 1 are shown again with a decision device 60 which which derives the value Di by comparison of the input signal y i  with the system pulse response l o , which is continuously up dated in accumulator 62 by comparison, in the exclusive or gate 61, of the signals Sgn Di and Sgn Yi, which latter is the sign of the error between the input signal and the nominal value of the digit signal which should be recieved from the system.

Title: Improvements in valve-gear adapted for use with automatic vacuum and air-pressure railway brakes
IPC: B60T13/46
Filed: 1921-03-07
Abstract: 185,769. Vacuum Brake Co., Ltd., and Walker, W. P. March 7, 1921. Fluid-pressure.- A valve by which a com. pressed air brake on a locomotive may be contrelled by the vacuum in the train-pipe of the vacuum brakes on the train comprises a piston b subject on one side to atmospheric pressure and to an adjustable spring e and on the other side to the vacuum in the train-pipe connected at m and to the pressure in the compressed-air reservoir connected at p acting upon the cup-shaped valve c, which normally cuts off this reservoir from the brake cylinder connected at n. The piston has a trunk part d which controls a port f<2> to atmosphere. A tappet-valve l<1> has a spindle l which fits loosely within the rod k of the piston, whereby normally the brake cylinder is open to the atmosphere by way of ports n<1>, n<2>, f<2>. When the vacuum in the train-pipe is destroyed to a degree dependent upon the adjustment of the spring e, the piston p is moved to unseat the valve c and admit compressed air to the brake cylinder. The valve l<1> is also unseated by contact of the rod l with the stud h so that compressed air is supplied to the chamber f<1>, the port f<2> of which is closed at this time; and when the pressure in this chamber reaches a value dependent upon the extent to which the vacuum has been destroyed in the train-pipe and connection m, the piston moves back and closes the valve. The uncovering of the port f<2> causes the valve to be reopened, an oscillating movement of the piston and valve being set up which, together with the effect of the spring e, delays the rise of pressure in the locomotive brake cylinder until the vacuum brakes on the train have become effective thereby avoiding the tendency of the carriages to overrun the locomotive.

Title: Clothes washing machine and controls therefor
IPC: D06F34/08
Filed: 1956-03-12
Abstract: 791,047. Washing-machines. PHILCO CORPORATION SOC. ANON. March 12, 1956 [Nov. 2, 1955], No. 7615/56. Class 138 (2). A washing-machine comprises a cylinder 32 for containing liquid and clothes, means for feeding liquid to the cylinder, a tub 50 for receiving liquid flowing from the cylinder, a duct 64, 74 for draining liquid out of the tub, a portion of the duct being arranged for normally collecting liquid in a static column, means responsive to the pressure of this column for interrupting the feed of liquid to the cylinder and including a pressure responsive element 76 having a surface for direct contact with the liquid in the duct, and means for forcibly expelling liquid through the duct and over the surface of the element 76. The pressure responsive means comprises a switch 72 adapted to be closed by the pressure of water on a flexible diaphragm 76. Water is supplied to the cylinder 32 through a spout 56 fed by a mixing valve 58 having mixed and hot water control solenoids 60, 62 respectively. When the cylinder 32 is full, water overflows into the tub 50 and duct 64, 74 and operates switch 72 to stop the supply of water. The switch 72 can be maintained closed even after overflow ceases by means of the pressure generated by an impeller 68 acting on the water trapped in the duct portion 74. The impeller 68 is driven by a motor 84 through a belt 86 which also drives a pulley 24 connected to a shaft 18. The upper end of this shaft carries an inclined extension member 36 connected through a bearing 38 with an agitator 30 which is of the wobble plate type and is connected to the cylinder 32 by a flexible boot 34. The cylinder 32 is connected to a tube 26 which is held stationary during agitation periods by a one-way drive spring clutch 46 acting as a brake against a housing tube 28 which is restrained from rotation by snubbing connections 48. For spin drying purposes the motor 84 is reversed and the shaft 18 coupled to the tube 26 by a one-way drive spring clutch 44. The impedance of the motor 84 is lower than that of the water supply solenoids 60, 62, so that when the motor is connected in series with either of the solenoids the liquid supply means is actuated but the motor does not start. The electrical circuit is such that hot or warm water may be selected for washing but warm water only can be supplied for rinsing and for spraying the clothes during the first spin drying period. The first rinse period includes two overflow rinses, and the last part of the second rinse is an overflow rinse. Specification 753,360 is referred to.
