Title: Improvements in or relating to motor vehicles
IPC: B60G21/05
Filed: 1933-09-29
Abstract: 414,238. Road vehicles. AUTOUNION AKT.-GES. WERK SPANDAU, 42, Berliner Chaussee, Spandau, Berlin. Sept. 29, 1933, No. 26878. Convention date, Sept. 30, 1932. [Class 108 (ii).] A motor vehicle has its springing so arranged that the longitudinal axis of inclination about which the vehicle tends to oscillate extends substantially through the centre of gravity of the spring masses so that transverse forces set up during travel do not produce oscillation about that axis. The axis about which the spring portion of a vehicle tends to cant or tilt when cornering is arranged to lie as closely as possible to the horizontal or substantially horizontal plane passing through the centre of gravity of the sprung portion thereby preventing canting. Fig. 6 shows transverse springs 13, 15 arranged in the plane B B passing through the centre of gravity, the wheel axles being also connected to the spring chassis by levers 30. In Fig. 2 only the rear spring 15 is arranged in that plane but the distance between the axis of canting C C and the centre of gravity of the spring mass is so small as to permit little canting. Fig. 7 shows an arrangement of the body &c. carried from the axles by pivoted levers 32, the spring 36 being disposed as shown. In this case the axis of canting, determined by the intersection of the lines connecting the points 34, 40 passes through the centre of gravity so that the moment of canting is nil.

Title: Process for desizing glass fabric
IPC: D02G3/18
Filed: 1961-07-26
Abstract: 921,650. Finishing fabrics. HESS, GOLDSMITH & CO. Inc. July 26, 1961 [Aug. 31, 1960], No. 27008/61. Class 42 (1). A process for desizing a sized glass fibre fabric comprises heating an advancing length of the fabric to a temperature sufficiently high to volatilize the size from the fabric, maintaining the fabric at this temperature for a time sufficient to volatilize at least 75% of the size, so diffusing the volatilized zize with air as to prevent ignition thereof adjacent the fabric, and subsequently raising the temperature of the fabric to a temperature sufficiently high to set the fibres thereof and volatilize substantially all the residual size thereon while diffusing the volatilized residual size with air to prevent ignition thereof in the vicinity of the fabric. The initial heating of the fabric is to a temperature between 800‹ F. and 1100‹ F. and the setting temperature is between 1280‹ F. and 1400‹ F. Preferably, one or more intermediate zones are provided to gradually raise the fabric temperature to the latter range to prevent thermal shock to the fabric. In some cases about 85-95% of the size is removed during the initial heating. In this zone the volatilized size is so diffused, preferably by providing a draught, as to produce a mixture thereof with air which mixture is too lean to ignite. A major portion of the size vapour is removed so that only a minor portion thereof enters the second zone. The process may be carried out in a vertical muffle furnace comprising at least three zones each of which is provided with vapour exhausting means. In a modification, the process is carried out in a muffle furnace comprising a single zone which subjects the advancing fabric to gradually increasing temperatures. U.S.A. Specifications 2,633,428, 2,665,125, 2,845,364 and 2,970,934 are referred to.

Title: Improvements in or relating to key-operated impulse sending devices
IPC: H04M1/272
Filed: 1927-10-12
Abstract: 303,921. Automatic Telephone Manufacturing Co., Ltd., and Ostline, J. E. Oct. 12, 1927. Semi-automatic exchange systems. - In an operator's keyboard equipment wherein any one key connects potential to one or more registering leads, an alarm is initiated (1) by the increased current through a. marginal relay if a number of keys are pressed simultaneously and (2) by a timing device if the interval between operation of successive keys is too short. The current through the marginal relay is the same whether a key connects potential to one or more than one of the leads. The invention is described as applied to system described in Specification 229,765, the digits being transferred over a distributing switch DD to storage-relay groups one of which is shown at A - - D. Keys 1 to 4 each energize one only of the relays A - - D while any of the remaining keys energize two of these relays, the circuit in each case extending over marginal relay MR and stepping relay DS. In the case of keys 1 to 4, current is fed over one of the relays A - D and a resistance R equal to that of each of the relays, so that the current over MR is the same as that fed over two of the relays when any of the remaining keys is operated. Depression of a key operates relay DS but not the marginal relay, and completes at 11 a circuit for the lower winding of two.step relay RT which operates its light armature 14 to prepare a full locking circuit for itself to ground at armature 16 of a normally energized slow-release timing-relay TR, The upper winding of RT is short-circuited at 11. On release of the key, DS falls back and RT operates fully to open the circuit of TR at 15 and prepare a circuit for alarm relay SR at 13. After an interval, TR releases followed by RT. Re-operation of DS by depression of a second key before release of RT completes a circuit over 11, 13 for SR which locks up over 18 and key CK, lights lamp AL at 17, and at 19 connects tone lead 21 to a lead 22 extending to operator's head-set. If two or more keys are pressed simultaneously MR is operated by the increased current and closes a circuit for SR with the results previously described. Operation of key CK releases the alarm and grounds the lead 20 which effects the release of the relays A - - D and homes the switch DD.

Abstract: 1,219,623. Transistor switching circuits; keying oscillators. HITACHI Ltd. 7 June, 1968 [19 June, 1967], No. 27290/68. Headings H3R and H3T. [Also in Division G5] In a switching circuit such as for an electronic musical instrument, a rectifying element such as a diode 32 is connected between a signal input 21 and the base of a transistor amplifier 22, a switch 23 is connected to the emitter of the transistor so that the amplifier 22 is conductive when the switch 23 is closed and time delay means 24 sustains the amplifier 22 conductive for a predetermined time after the switch is opened and exponentially attenuates the amplitude of the output signal and the rectifying element 32 is forward biased when the switch 23 is closed and reverse biased when the switch 23 is open. As shown, the diode 32 is reverse biased and transistor 22 is OFF so that the signal from tone generator 21 which may be pulse or sine wave is blocked from the output 33. When the key switch 23 of an organ is closed the bias at points 34, 35 changes to forward bias the diode and turn ON the transistor 22 so that an output occurs at 33. When the key 23 is opened, switching OFF and reverse biasing of the diode is delayed by the charging of capacitor 29 through resistor 28 so that the output is reduced over a time delay. A plurality of PN junctions could replace the diode 32. Alternatively the base emitter junction of a transistor could be used in place of diode 32. In a modified circuit (Fig. 3, not shown), the signal source is connected between the diode and collector load supply which is earthed together with the terminal corresponding to +V 4 , the switch and capacitor 29 being connected to a negative supply (- V 5 ). When the diode 32 is blocked it prevents the signal being transferred to the output 33 which would be the case via the base-collector capacitance (14), Fig. 1 (not shown) as is known even although the transistor is biased off.
