Title: Improvements in vehicle shock absorbers and suspension systems
IPC: F16F9/32
Filed: 1950-03-22
Abstract: 674,379. Hydraulic shock absorbers. McINTYRE, B. D., McINTYRE, W. D., and McINTYRE, C. S., (trading as PATENT DEVELOPMENT CO.). March 22, 1950 [April 21, 1949; Nov. 17, 1949]. No. 7196/50. Classes 108(ii) and 108(iii) In a direct-acting hydraulic shockabsorber of the kind having two series 79, 81, Fig. 4, of flow ports extending through the piston 29 controlled by valves 91, 89 and a base valve body 31 having two series 97, 99 of flow ports and associated lower and upper valves 109, 107, the piston rod 33 is provided with a wear-resistant surface, e.g. by being chromium-plated, and abutment means is provided in the piston, and on the base valve body, in order to prevent damage of their associated valves by " bottoming " of the piston rod. The usual tubular dust shield is dispensed with. The outer end of the rod, Fig. 3, is of reduced diameter and is resiliently secured to a vehicle frame member 53 which is shaped so as to partially surround and thus protect the rod. On the reduced inner-end of the piston rod are clamped a spacing washer 87, piston body 29, and laminated disc valve 91, by means of a nut 93 which forms the abutment for a spring 113 loading the valve 91. The disc valves 109, 107 are mounted on respective bosses 121, 119 and integral with the member 31. The boss 121 is turned over by a spinning operation to retain the valve 109. The boss 119 is similarly turned over to retain a spacing member 125 on which the valve 107 is mounted. In a modified construction (lower part of Fig. 3) (not shown), the nut 93 clamps directly on to the disc valve 91 and the spring 113 is omitted. The valves 107, 109 are retained by a rivet mounted in a central aperture of the member 31. The shock-absorber may be mounted concentrically within a coil spring acting between a transverse frame member, Fig. 1 (not shown), and a lower wishbone link of a vehicle independent front-wheel suspension. As applied to a rear wheel suspension, Fig. 2, the lower end of the shock-absorber has a ball-joint connection to the axle 63 and the upper end of the piston rod is resiliently connected to a vehicle body portion 73 which acts' as a stone protector and deflector for the rod.

Title: Improvements relating to suction devices for supplying fuel to explosion engines
IPC: F02M37/02
Filed: 1926-03-16
Abstract: 256,883. Deuta-Werke, vorm. Deutsche Tachometerwerke, Ges., (Assignees of Arndt, J.). Nov. 3, 1925, [Convention date]. Vacuum apparatus. -In suction apparatus for raising fuel for internal-combustion engines, a spring-pressed valve c cuts off the fuel chamber g from the suction pipe k, when the suction is low and a small port a in the atmospheric valve b admits atmospheric pressure so that the chamber g then acts as a gravity-feed to the carburettor. When suction is normal, the valve c is open and fuel enters the chamber g until a float f raises a valve d to cut off suction. Air then enters through the port a and reduces the vacuum so that the air valve b may open under the pressure of its spring.

Title: Improvements in course indicators for radio direction systems
IPC: G01S1/02
Filed: 1939-03-07
Abstract: 526,055. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. March 7, 1939, No. 7410. [Class 40 (v)] The ratio of the strength of two currents of different frequency is automatically accentuated by feeding the currents to a dynamometer arrangement comprising two fixed coils, set at an angle to each other, and a moving coil coupled to an output or indicator circuit, stops being provided for arresting the moving coil on each side of the balanced position. The method can be used to distinguish, either orally or visually, the two complementary tone-frequencies used in a radio-navigational system. As shown in Fig. 2, signals of frequency f1 are fed through a tuned filter-circuit Cl, L1 to the coil F1, whilst signals of frequency f2 are fed to the same coil through a filter-circuit C2, L2, the currents being displaced in phase by 180 degrees. Simultaneously, currents of both frequencies are fed through an adjustable resistance R1 to the coil F2 with a phase-retardation of 90 degrees. The combined fields due to f1 and f2 will then be inclined to each other at an angle which depends upon the relative strengths of the signal currents in the coils Fl, F2. Signal currents are also passed, in-phase for both frequencies, through a resistance R2 to the moving coil M, which feeds an indicator or output valve V. When the two signals are equal across the input transformer T1, there will be no resultant torque on the moving coil M, though any unbalance will tend to cause that coil to set itself in line with either coil Fl or F2, the sensitivity or amount of the deflection being controlled by the value of the resistance R1. Movable stops are placed on the meter at positions in which say the signal f1 is zero and only the signal f2 can be heard, or vice versa. The dynamometer may be used directly as a visual indicator:

Title: Improvements in the electrical reception and transmission of pictures
IPC: H04N3/12
Filed: 1930-03-11
Abstract: 356,760. Television. BRONK, 0. VON, 12, Hallesches Ufer, Berlin. March 11, 1930, No. 7849. [Classes 39 (i) and 40 (iii).] A television transmitter or receiver comprises a screen made up of a set of linear glow lamps which light up in succession under the control of voltages applied through time-lag circuits in the manner described in Specification 277,761, [Class 40 (iii) Telegraphs, Electric]. Thus at the transmitting station, Fig. 4, the light from a battery of successively ignited vertical discharge tubes 1 may fall upon a transparent picture 2, after leaving which it is focused on a light-resistance cell 4. Scanning in the vertical dimension may be obtained by means of a slot 5 in a moving screen (Fig. 1, not shown, and Fig. 4), or by movement of the object where this is a kinematograph film. The light may in this case be focused by means of cylindrical lenses (Fig. 2, not shown), or the tubes may be end-on to the film (Fig. 3, not shown). In the arrangement shown in Fig. 4 voltage impulses are applied, in parallel with a condenser and with a source of primary voltage 14, by an induction coil 16 to a number (such as a hundred) of discharge tubes 1 through a tapped inductive resistance 18 which produces a differential phase-lag so that the tubes light up in succession and effect scanning in the horizontal dimension, while the slot 5 (which may be a radial slot in a revolving disc, Fig. 5, not shown) effects scanning in the vertical dimension. The wireless transmitter 24 is modulated by picture current from the photo-electric cell 4, and in addition it is modulated at the spark frequency, such as 1000 #, of coil 16 by way of transformer 22. At the receiver (Fig. 5, not shown) the arrangement is similar; the spark-frequency impulses applied to the discharge tubes are superimposed on the picture-current voltage and have a priming effect, so that those tubes light up in which the resultant voltage is sufficiently high. The speed of the slot 5 at the receiver is controlled by a local motor. In a modification a rotating mirror may be used instead of the moving slot 5. Shape of apertures. The number of the tubes 1 may be reduced, so that the shape of the " apertures " becomes rectangular, the width of the slit 5 being less than that of the tubes 1. Transmission of opaque figures. In the modification shown in Fig. 6 the tubes 1 at the transmitter are arranged end-on to an oscillating mirror 43 and the light, after being focused by a cylindrical lens 41, is reflected by the mirror on to an opaque object 44 and thence via a paraboloidal mirror 45 to a light-sensitive cell 46. Vacuum apparatus. A glow lamp for use as a reproducing screen for a television receiver comprises a number of cathodes 52, Fig. 7, associated with separate anodes a and a common control electrode 51. Signals are applied to the electrode 51 directly through a transformer T and to the anode a through time-lag circuits 63 having different time-constants.

Title: Improvements in or relating to method of and apparatus for handling cotton or the like fibrous material
IPC: B02C13/286
Filed: 1933-03-16
Abstract: 418,134. Opening and conveying cotton &c. SACO-LOWELL SHOPS, 147, Milk Street, Boston, U.S.A. March 16, 1933, No. 8048. Convention date, April 4, 1932. [Class 120 (i).] In a method of handling cotton and similar fibrous material which consists in beating the material, conveying it from the beater in a stream of air, separating it from said air stream, and filtering the air stream subsequently to said separation, the air is humidified prior to being brought into contact with the fibrous material and is re-used in the handling of additional fibrous material. Thus the warmed and humidified air in a room can be used in the machines in that room and can be returned to the room after filtering. In the arrangement shown cotton is delivered from the opening room by a pneumatic conveyer 3 and a belt conveyer 2 to two picker systems A, B. Each system comprises a supply hopper 5 feeding the cotton automatically to the beater unit 6 of a breaker unit and a condenser 7 which discharges the cotton to a hopper feeder 9. The feeder 9 delivers the cotton to the beater 10 of a finisher lapper including a condenser section 12. Cotton is carried away from the beater 6 by the current of air induced by a blower 16 and drawn into the machine through a grating 15. After the air has been separated in the condenser from the cotton the air current passes through a pipe 20 to a filter 21 from which the air is discharged again into the room. Pipes 22, 23 lead from the condensers 12 of the beaters 10 to other filters 24, 25 also discharging into the room. Each filter is preferably of the kind described in Specification 418,195, [Group XXVIII], in which the filtering is done by a highly pervious layer built up of the fibres carried by the air stream and trapped between double wire screens of the filter. The air stream is periodically stopped to allow the filter to clear itself. The air used in the opener room may be discharged in the picker room and vice versa.

Abstract: 492,047. Moving signs. EBERHARDT, A. March 18, 1937, No. 8057. Convention date, March 19, 1936. [Class 3 (i)] Reel and non-endless display band apparatus of the type in which power is applied to one or the other roller according to the direction of wind, comprises a friction drive consisting of discs 20, 21 having wedge rims which engage constantly with a recessed-rim wheel 27 and one-at-a-time with recessed-rim wheels 18, 19 on the roller shafts 14, 15. The wheel 27 is carried by a shaft 6 turned either by a handle 5 or by a motor, and the wheels 20, 21 are mounted in slidable bearings in a rocker-frame 24, the bearings being pressed inward by springs 83 to give the wheels 20, 21 a frictional grip on the wheel 27. By reason of this grip the frame 24 is rocked with the shaft 6 in the direction in which the handle 5 is turned, till the wheel 20 or 21 engages the wheel 18 or 19 respectively to turn the roller 7 or 8. To prevent the free roller from over-riding the band by its rotational momentum, a brake is automatically applied to the free roller. The brake pads 40 or 41 are carried by a lever 34 pivoted at 36 and furnished above the pivot with a pin 35, which is adapted to be struck by one or the other of two fingers 32, 33 carried by a clamp ring 31 frictionally gripped on the shaft 6. An opening 39 in the upper part of the lever 34 takes over the shaft 6, and a wheel 50 on the bottom of the lever rides over a spring .hump 52 to position the lever on one side or the other of the medial line. The ring 31 has a tightening screw 30, whereby the pressure of the brake on the roller flange rim during turning can be adjusted. An arm 42 on the lever 34 projects through a slot 43 in the casing to contact with two limiting screws which prevent excessive brake pressure being applied. The display band 9 passes round rolls 48, 49 over a table 66, and is exposed to view by lifting a hinged lid 57. A supplementary non-endless band 88 may be provided winding on and off rollers 84, 85, the roller 85 being driven by a chain &c. from the spindle of roll 48. This chain carries a pointer indicating matter on the inside of the lid 57, and has a turn-up handle whereby the chain can be pulled around to bring the bands 9 and 88 into a new relation. The rollers 84, 85 are coupled together by cranks, friction discs, &c., or by fusees 95, 96 on which winds a cable 94. Instead of the supplementary band 88 there may be provided a plurality of independent display sheets 72c, Fig. 11, riding over curved prongs 71 carried by a shaft 67 which can be turned by a milled wheel to swing the sheets back on a support 69. A spring on the shaft 67 frictionally holds the device in situ. Specification 416,699 is referred to.
