Title: Improvements in or relating to gyroscopic toys
IPC: A63H11/14
Filed: 1921-11-23
Abstract: 193,168. Dew, S. T., and Trautmann, F. O. Nov. 23, 1921. Mechanical toys.-A mechanical toy comprises a doll or other figure provided with a gyroscope or weight for maintaining it in an upright position and with means for rotating a wire &c. representing a skipping rope. The toy may travel on a wire or rail, or on a flat surface, and may be provided with propelling means and means for jumping the figure. The frame 9, Fig. 1, carries a spindle 4 passing through the arms which are connected with a wire 14 having a flexible cord central insertion 16 for passing under the supporting wheel 10. The wheel 10 is driven by a vertical spindle 1 on which is mounted a momentum wheel 5 and a winding capstan 2 the upper surface of which drives a friction disc 3 on the spindle 4; the wire 14 is counterbalanced by a weight 15 on the spindle. The lower end of the spindle 1 may be conical and the wheel 10 made in two parts one of which is magnetic to secure adhesion of the spindle. The periphery of the wheel may be serrated to facilitate passing over the slipping rope 16 or may be provided with a rubber tyre. The spindle 1 may bo horizontal and drive the spindle 4 through friction gearing, a pair of supporting wheels 10 arranged tandem fashion being provided; in this form the toy travels by gravity or by the engagement of the rope with the supportfing wheels. In a further modification the spindle 4 is driven by clockwork and the rope is divided, the ends being provided with beads of rubber which propel the toy by striking the supporting surface. The toy is supported on four wheels 10 between which is arranged a balancing weight. In a further modification a gyroscope is driven by clockwork which also drives the spindle 4. Fig. 20 shows a form in which the toy is maintained vertical by a gyroscope 5<a> mounted on ball bearings and a stirrup 21 is provided which carries the feet 18, a spring 20 being provided between the feet and the main frame. The spindle 4 is rotated by clockwork and is provided with a cam 23 which engages a roller 22 on the stirrup 21. On the rotation of the spindle 4 the spring is gradually compressed, being released by the disengagement of the cam 23 with the roller 22; the sudden reaction causes the toy to jump. In further modifications the supporting wheels are driven through crank or toothed gearing.

Title: Device for the automatic recognition of speech
IPC: G10L25/15
Filed: 1965-07-23
Abstract: 1,109,496. Automatic speech recognition. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 23 July, 1965 [29 July, 1964], No. 31454/65. Heading G4R. In apparatus for recognizing spoken words signals representing the words are tested at regular intervals for the presence of two component frequencies a store being set whenever the corresponding frequency is present and, at the end of the word, the outputs from the stores are combined to identify the word. The stores set depend upon the sequence in which the corresponding frequencies appear. The speech signal W, Fig. 1, is divided into a low frequency fundamental wave a and the high frequency wave b. The output from L.P. and H.P. filters are applied to Schmitt triggers which, when the signal reaches a certain value, set corresponding flip-flops. These are reset by timing pulses from a timing pulse generator so that the signal is tested repeatedly. The outputs of the flip-flops are combined in gates and five flip-flops are set according to the order of occurrence of the frequencies. " N ", " S " and " I ", Fig. 2, indicate groups of sounds, " NI indicating that the N sound appeared before the I sound and N2 indicating that it occurred after. The outputs from the five flip-flops are combined in gates designed to identify the word spoken. Storage flip-flops energize indicators. The timing pulses may be derived from local maxima of the speech signal.

Filed: 1937-11-16
Abstract: 484,974. Hand-irons. KELLNER, L., KELLNER. M., and GEBERT, V. Nov. 16, 1937, No. 31468. Convention date, Aug. 27. [Class 138 (ii)] [Also in Group XI] In an electric hand-iron having steaming means the portion 9 of the sole plate adjacent the steam-discharge orifice 5 is arranged to be cooler than the rear portion 10 whereby the steam issuing from the orifice is condensed into the goods being ironed and is subsequently reevaporated therefrom by the heat of the rear part of the iron. The steam valve is arranged to be opened only on the forward movement of the iron, the normal action of the hand of the user on the pivoted portion 6 of the handle opening and closing the valve through the lever 23. The pivoted portion may however be latched to the main portion at 11 to retain the valve open for both directions of movement of the iron. The two portions of the sole plate are separated by a groove 12 and the front portion of the iron is jacketed with material such as sodium sulphate 15 which melts or loses its water of crystallization and so absorbs heat. The heating element 2 which is provided above the rear portion only of the sole plate, is supported partly by a bimetallic strip 21 which, on the temperature of the rear plate becoming excessive, raises the heating element somewhat. The water container 1 is similarly partly supported by another bimetallic strip. The degree of heat may be controlled by a switch 13 and thermostat 14. The water chamber is provided with a baffle 22 and the steam valve is arranged to open, independently of the operation by the handle 6, by the steam at a predetermined pressure.

Title: Improvements in or relating to valve tappets
IPC: F01L1/25
Filed: 1935-11-14
Abstract: 466,161. Valve gear. WILCOX-RICH CORPORATION. Nov. 14, 1935, No. 31568. Convention date, Nov. 14, 1934. [Class 7 (vi)] A valve-actuating tappet, particularly for internal-combustion engines, is provided with hydraulic means for taking up slack or clearance comprising a cylinder 30, with an extension 31 acting as an oil container, fitted within the hollow tappet 23 and provided with a plunger 46 pressed outwards by a spring 52, the arrangement being such that the tappet may be used in the inverted position shown in Fig. 2, with an overhead cam, or in an upright position with the roller or head 26 at the lower end, the cylinder 30, 31 in the latter case being inverted within the hollow tappet, so that the plunger 46 is pressed outwards from the open end of the tappet and the oil container 31 is within the closed end of the tappet. In this way, the container 31 in both cases occupies the lower part of the tappet, so that the oil is forced upwards through a depending pipe 40 and past a ball valve 44 into the space beneath the plunger 46. Air or gas contained in the oil collects at the top of the container 31 and escapes at 73. The tappets may also be arranged obliquely or horizontally, and in a radial-cylinder engine are arranged radially around a central cam. The oil is first supplied to a reservoir adjacent the tappet guide, so that air or gas may collect in the top of the reservoir and escape through a passage leading to the inside of the tappet guide. The spring 52 is of rectangular crosssection and is fitted into a recess at the top of the cylinder 30 so as to act in conjunction with a shoulder 54 on the plunger 46, to limit the outward movement of the plunger. The plunger is recessed at 53 to avoid frictional contact with the spring except at its upper end. The cylinder 30 is so machined that a slight percolation of oil occurs between the plunger and cylinder, and in an engine the amount of percolation in the several tappets is tested before the springs 52 are fitted, by filling the cylinders with petroleum and placing equal weights on the plungers. A tool used for driving the head 41 of the pipe 40 into the bottom of the cylinder 30 comprises a stem formed at its end with a socket to fit over the ball valve 44. Fig. 6 shows a modification in which the cylinder 86 has slight axial play between a shoulder 83 and an adjustable screw collar 93, under the control of a spring 96, to allow for wear or inequalities in the surface of the cam. The plunger 97 may be provided with a cap 102 having a hollow extension 104 fitting within the plunger and made resilient by slots 105. Alternatively, wear or inequalities in the cam surface may be allowed for by providing small pockets in the inner end of the tappet plunger, in which air or gas collects so as to form a compressible medium giving the slight play necessary.

Title: Impulse senders
IPC: H04M1/272
Filed: 1953-11-16
Abstract: 735,620. Automatic exchange systems. AUTOMATIC ELECTRIC LABORATORIES, Inc. Nov. 16, 1953 [Dec. 30, 1952], No. 31747/53. Class 40 (4). An impulse sender comprises a group of electron tubes arranged in a counting circuit with digit means for energizing certain tubes to register the complement of the digit in the circuit, such energization causing a pulsing device to operate and the counting circuit to count the pulses emitted, the pulsing device being halted when the counting device has counted out the appropriate number of pulses. First embodiment.-When lead S, Fig. 2, is grounded relay 210 operates to energize thyratron tubes X, Y, Z, Fig. 3, of a three-stage binary counter. 210 also operates relay 310 which energizes relay 320. Operation of a digit key, Fig. 1, applies a voltage to one or more of condensers C1-C4 and energizes relay 220 which operates 230 to prevent leakage from the condensers. The condensers energize the appropriate tubes S1, S2, S4, S8 of the counter to enter the 12's complement of the selected digit. The anode current of the energized tubes operates relay 340 which restores 320 and causes pulsing relays 350, 355, 360 to interact and pulse the line at contacts 363. At contacts 362, relay 360 also pulses the counting circuit which steps on as each pulse is sent to line. When the counter reaches 12, S4 and S8 are both conducting and energize tube GS which operates relay 370. 370 breaks the circuit to the pulsing relays 350, 355, 360 to stop the count and operates relay 380 which discharges the condensers C1-C4, extinguishes the counting tubes and restores relays 310 and 330, the former releasing 340. Relay 380 also connects the grid of tube S8 to a timing circuit so that at the end of the interdigital pause S8 reoperates to energize relay 395 which energizes magnet M2 and extinguishes tube GS to restore 370 and 380. Release of 380 extinguishes tube S8 to release 395 and M2 so that rotary switch RS2 steps on and the impulse sender is ready to respond to the next digit. Second embodiment.-In a modification (Fig. 5, not shown), cold cathode tubes are used in the counting circuit and to replace the condensers C1-C4. The rectifiers between successive stages of the counter are therefore dispensed with.

Title: Electric continuous-flow heater having a plurality of heating channels
IPC: F24H1/10
Filed: 1961-09-06
Abstract: 969,785. Electric flow heaters. A. ECKERFELD. Sept. 6, 1961 [Sept. 9, 1960; Jan. 24, 1961], No. 31967/61. Heading H5H. The water in a continuous flow heater flows successively through a plurality of channels containing heating coils in direct contact with the water, the heat generated by the coils per unit length of channel being less at the exit than at the entry end of the heater. Water flows from the inlet 6, Fig. 1, to the outlet 9, and is heated by the three equal coils 10, 11, and 12, mounted in channels 2, 3, 4, and 4<SP>1</SP> in the insulating block 1, coil 12 occupying the two channels 4 and 4<SP>1</SP>. A three-phase supply is connected to the coils at R, T, and S, and making or breaking of the neutral point connection at the other end of the coils by a flow actuated switch (not shown), switches the heater on or off. If, due to a coil fault, the voltage at the upper end of channel 7 or 8 rises from its normal approximately zero value, the water columns in those two channels constitute protective resistors with respect to the water flowing into and out of the heater. In the embodiment of Fig. 3, equal coil lengths are arranged in each of the four channels, and are fed by phases R, S, and T as indicated, breaking of either of the neutral point connections 19 and 20, by a switch, causing the heater to operate at half power. A further embodiment (Fig. 2, not shown) employs only two heating channels.
