Title: Improvements relating to servo-operated or servo-assisted steering means in motor vehicles
IPC: B62D6/02
Filed: 1957-07-08
Abstract: 810,716. Vehicle power steering. DAIMLER-BENZ A. G. July 8, 1957 [July 18, 1956], No. 21593/57. Class 79(5). In a servo-steering system for a motor vehicle a centrifugal device driven in accordance with the vehicle speed provides increasing opposition to the movement of the servo slide valve as the vehicle speed increases so as to reduce the servo assistance. In one example the centrifugal device comprises a governor 36, Fig. 1, connected to the vehicle transmission and actuating a reducing valve 35 in a pipe 33 from an auxiliary pump 37 to obtain pressures which increase as the vehicle speed increases. The line 33 is connected to two points on a servo valve 10 and according to the movement of the valve slide 11 by rotation of the steering ball-nut 4 fluid passes through one or other of passages 32, 32<SP>1</SP> to actuate pistons 31, 31<SP>1</SP> in the ends of the slide 11 to resist the movement of the slide. The pressure in the line 33 may also be used to reduce the pressure in the supply line 23 from the main pump 24 at the higher vehicle speeds so that pressures in the servo cylinder 15, 16 are also reduced at higher speeds to reduce the servo assistance. The line 33 is connected by a pipe 41 to a differential regulator valve 39 which permits the pump 24 to blow-off through a return port 42 when higher pressures are reached in the pipe 33 at the higher vehicle speeds. In another embodiment a pressure which varies according to the vehicle speed is obtained from an auxiliary pump 84, Fig. 2, in combination with a double piston valve 85 having a revoluble casing connected to the vehicle transmission and carrying a weight which actuates the valve through centrifugal force. At low speeds the valve 85 permits the oil flow to return direct to the tank 50 but progressively shuts off as the speed increases to build up the delivery pressure in the line 83. In this example the pressure in the line 83 indirectly influences the pressures in spaces 77, 77<SP>1</SP> behind restoring pistons 78, 78<SP>1</SP> of a valve slide 46 through a system of piston manometer devices 63, 63<SP>1</SP>. Each device comprises a piston 64 balancing a reducing valve 69 through a weight-beam 67 pivoted on a movable fulcrum 70 attached to winging arms 71. Each piston 64 and valve 69 is connected to one end of the servo cylinder 60 through lines 62, 74 and supply reduced pressure line 75 connected to one of the restoring pistons 78 to provide a restoring bias according to the setting of the swinging arm 71. Movement of the swinging arms 71 is governed by a spring- loaded piston and cylinder 81, 82 connected to the variable pressure line 83 from the centrifugal valve 85.

Title: Improvements in or relating to twin sole-laying presses
IPC: A43D25/06
Filed: 1932-08-03
Abstract: 402,540. Boot-making machines. MICHALK, O., 27, Daheimstrasse, Freital, near Dresden, Germany. Aug. 3, 1932, No. 21828. Convention date, Aug. 3, 1931. [Class 17 (i).] Sole-laying.- A twin sole-laying press with air pressure pads for engaging the soles and pressure applying devices operated by compressed air for clamping the work upon the pads is provided with controlling means for the two presses arranged for alternate working, the means for clamping the work on one press co-operating with means for releasing the work on the other press. A reservoir 3<1> for compressed air communicates by pipes 3 with two control valves each having a plate 2 for engagement by the foot and a plunger 21 urged upwardly by springs 2<11>, 2a which come successively into operation as the head is depressed. The plunger has two necks b, c which co-operate with an exhaust opening 5<1>, a pipe 4 leading to a pressure reducing valve 4<1> and a pipe 5 leading to a cylinder 6. A piston in this cylinder has a head 6<11> actuating a lever 71 carrying a work clamp 7 and a cylinder 11 the piston of which is linked to a pawl 9 co-operating with a rack 10. Between the two heads 6" is a multiple valve comprising a horizontal plunger 14, with necks e, e<1>, g, g<1> actuated by cams 6a on the heads, and a parallel plunger 13 with a neck f co-operating with ports h, h<1> and a port 19 leading to the reservoir 3<1>. The plunger 13 is actuated by inclines on pivoted fingers 15 on the descent of the heads, the fingers yielding as the heads ascend. The necks on the plunger 14 co-operate with exhaust ports 24, 25 a passage 21 leading to the pressure pad 8 of the left-hand press, a passage 20 leading to the pressure pad of the right-hand press, a passage 17 leading to the cylinder 11 of the left-hand press, and a passage 17<1> leading to the cylinder 11 of the right-hand press. With the parts in the position shown the work on the right-hand press is under pressure and the work on the left-hand press has been released. A new workpiece is positioned and the head 2 of the left-hand valve is partially depressed. Its head 6<11> rises actuating the lever 7<1> and shifting the plunger 14 to the right. This shift opens the ports 17 and 20 to exhaust, thus releasing the pawl 9 of the left-hand press and deflating the pressure pad of the right-hand press, and connecting ports 17<1>, 21 to the port h<1>. The head 2 is then fully depressed, against the second spring 2<11>, high pressure air then passing by the pipe 5 direct to the cylinder to give a heavy thrust to the lever 7<1>. The head 2 is then released opening the passage 5 to exhaust. The head 6<11> drops, its finger 15 moving the plunger 13 to the right, thus connecting the port h<1> to the pressure pipe 19, withdrawing the pawl of the right-hand press and inflating the pad of the left-hand press. The work piece in the right-hand press may now be changed.

Title: Television radio transmitter
IPC: H03C1/24
Filed: 1935-08-02
Abstract: 450,057. Valve modulating circuits; thermionic valves. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Aug. 2, 1935, No. 21922. Convention date, Aug. 9, 1934. [Classes 39 (i) and 40 (v)] In a modulating system for impressing television signals on a carrier wave, the signals and the carrier input are applied to separate grids of the modulating valve, the output circuit of which is tuned to an harmonic of the input carrier wave. As shown in Fig. 3, the carrier source 3 is coupled to the circuit of a grid 16b, and the picture signals are applied through a choke 5 and condenser 4 to the grid 16a. The grid 16a is biassed, to preclude grid current, through a leak resistance 6 shunted by a condenser 18 which has high reactance at the picture frequency, but low resistance at the radio frequency. The grid 16b has a fixed bias which may permit grid current but is such that only positive peaks of grid potential affect the anode current, thereby enabling the anode circuit 10 to be tuned to a multiple of the frequency of the source 3. The coupling afforded by the inherent capacity 17 between the grids does not induce any substantial oscillatory voltage on the grid 16a, on account of the low reactance of the condenser 18 at the carrier frequency. In a modification shown in Fig. 3a, the grid circuits are electrostatically isolated from each other by a balancing arrangement comprising a coil 2a coupled to the coil 2 and connected to the grid 16a by a condenser 19 of about equal capacity to the inherent capacity 17. The two grids may be of the same diameter and intermeshed, or one may be of larger diameter than the other with a screen interposed. In a further modification, the carrier is applied in push-pull to the symmetrical grids 16a, 16b, the picture signals are applied to a further negative grid, and a positive screen is interposed. Specification 435,561 is referred to.

Abstract: 479,771. Current, voltage, capacitance and resistance measurements. SIEMENS & HALSKE AKT.-GES. Aug. 10, 1936, No. 22047. Convention date, Oct. 3, 1935. [Class 37] Alternating-current apparatus for measuring or recording complex quantities wherein a preferably automatic balance or compensation of a quantity to be measured is effected, includes an amplifier having in its output circuit a wattmetrical instrument, for example of the induction type and functioning as a reversing motor and zero instrument, rotation of the armature varying impedances in order to compensate the circuit in respect of a component being investigated. In Fig. 1, a potential Ux to be measured is fed to the points O1, 02 on slide wire resistors R1, R2, the contacts K1, K2 being driven by the rotors A1, A2 of induction instruments and their movement to balance point indicating the unknown. The voltage windings S<1>1, S<1>2 of the instruments are supplied from a phase-shifter Ph and produce fluxes displaced by 90 degrees, the current coils S<11>1, S<11>2 being connected in series in the output of amplifier V. A comparison or balancing potential continuously adjustable as regards phase and magnitude is taken from the four parts of the resistors R1, R2, namely from O1-I ..... O2-IV, since the resistors are respectively connected across a pure ohmic resistance R and a total impedance Rc, C, and T1. Fig. 3 shows bridge apparatus for measurements on an unknown capacitance Cx. The bridge is fed through transformer Th and a second transformer may be employed for energizing at lower potential the bridge part containing the standard condenser Cn. The wattmetrical instruments M1, M2, respond to the power component of the current and the wattless component, and the resistors are calibrated in terms of loss angle and capacitance. The contacts K1, K2 can be connected to recording pens. Specification 478,880 is referred to.

Title: Process for the manufacture of dyed and durably crimped fibrous materials of linear polyesters
IPC: D06P3/54
Filed: 1955-08-02
Abstract: Dyed and durably crimped polyester fibres are produced by impregnating the stretched or unstretched polyester filaments, before, simultaneously with or after their formation into a tow, with an aqueous dispersion of a waterinsoluble dyestuff or an aqueous solution of a water-soluble developable derivative of such a dyestuff having an affinity for the fibres, removing excess liquor from the filaments in the form of a tow, stretching if the filaments are not already oriented, drying, mechanically crimping and then fixing the dyeing and the crimp by steaming under pressure.  Impregnation with the dyestuff liquor may also be effected both before and after stretching, when effected.  The tow may be cut into staple fibres before or after steaming, or alternatively it may be worked up into a roving or yarn.  Steaming may be effected at 110-140 DEG  C. on the tow while free from tension or under compression.  Crimping is preferably effected in an obstruction crimping apparatus.  Specified water-insoluble dyestuffs are dispersed acetate dyestuffs, dispersed vat dyestuffs and vat-acid leuco compounds of vat dyestuffs, and as water-soluble developable derivatives of dyestuffs, there may be employed esters of leuco-vat dyestuffs and easily splittable esters of azo dyestuffs or of aminoanthraquinones containing hydroxy groups reactive with polyvalent acids.  To the impregnating dyestuff liquor may be added swelling agents, dyestuff carriers, lubricants and textile assistants having an anti-static action and thickening agents, several of which are specified.  The steamed tow may finally be washed and dried, a second crimping operation, if desired, being effected on the tow either before or after drying.  Spin-dyed filaments may be treated.  Examples are given.  Specification 327,394, [Class 15 (ii)], is referred to.
