IPC: B60G11/36
Filed: 1921-09-21
Abstract: 182,724. Edwards, C. K., and Associated Equipment Co., Ltd. Sept. 21, 1921. Spring shackles. - Relates to spring suspensions of the kind in which a main bearing-spring is connected to an auxiliary spring, acting in opposition to the main spring, by means of a lever arranged so that when the vehicle is lightly loaded, the effective leverage of the main spring is large and that of the auxiliary spring is small, but when heavily loaded. the leverage, of the main spring is small and that of the auxiliary spring large. According to the invention, the springs and lever are disposed so that the lines of action of the main and auxiliary springs are respectively substantially perpendicular and away from the perpendicular to the corresponding arms of the lever when the vehicle is lightly loaded, while, when the vehicle is heavily loaded, the distortion of the main spring and the rocking of the lever bring these lines of action respectively away from the perpendicular and substantially perpendicular to the corresponding arms of the lever. As shown, the main spring 27 is connected by a shackle 26 to one arm 24 of a lever pivoted on a chassis-bracket 22, the other arm 25 of the lever being connected by a link 28 to a volute spring 29 seated in a bracket 30 on the chassis. The connection between the spring 29 and link 28 comprises a cupped seating 31 engaging a corresponding part 32 on the link. The suspension is shown in the position it assumes when the vehicle is lightly loaded.
Patent GB-251899-A (GB)
Abstract: 251,899. Rudolph, M. Dec. 19, 1925. Stitching tufts to fabrics; grouped machines.-An apparatus for making artificial locks of hair consists of two sewing-machines to which the materials pass in succession. At the first machine the fibres a, Fig. 1, are stitched down on a paper strip c; they are then folded over by a folding guide to the position shown in Fig. 1<a> and finally are doubled back near the stitching line b and stitched again by a line of stitches b<1> as shown in Fig. 1<b>. A machine A to which bundles a of hair are fed is provided with a hood 3 pivoted between brackets 1 and depressible against spring action to allow the bundles to pass beneath a spring mounted claw 12 adjustable by a lever 16. The hood is connected to a carriage 8 which is withdrawn from proximity to the claw 12 by the backward movement of the hood and on release thereof presses the bundle under the claw to the needle d. The strip c with the bundles attached passes on to a bar 18 by which the longer ends a<1> of the hair bundles are turned over upon the shorter ends. This bar is inclined upwards and bent back at its end 19 which is perforated at 20 to allow the operator to observe the stitching of the second machine B. The doubled bundles attached to the paper strip are engaged by a curved member which produces a kink in the bundles prior to the insertion of the stitches b<1> by the needle d<1>. The bundles are fed between the two machines by a belt 28 carrying studs 27 which are caused to take an inclined position as they advance owing to the twisting of the belt caused by the setting of one of its pulleys 29 at an angle to the other.

Title: Arrangements for operating a printing element
IPC: G06K15/06
Filed: 1974-06-07
Abstract: 1425300 Control systems for piezo-electric printing hammers SIEMENS AG 7 June 1974 [31 Aug 1973] 25402/74 Heading H2H The printing elements of a printing apparatus are operated by means of piezoelectric transducers, each printing element being accelerated away from its associated transducer from a rest position to a printing position when a voltage is applied to the piezoelectric transducer to cause expansion thereof from its contracted state, the printing element thereafter rebounding from the printing position into contact with the transducer, circuit elements being provided which sense when the printing element has returned into contact with the transducer and serve to apply to the transducer a further voltage which then causes contraction of the transducer. Such a system substantially eliminates vibrations of the printing elements. With no pulse on a line T, transistors T4, T3, T2 are all blocked so that transistor T1 conducts to apply a voltage +U1 to the piezcelectric transducer PW which maintains it contracted. The application of an operating pulse to a line T by way of a time controlled switching unit ZS1 causes conduction of a transistor T4 and, thereby, of transistors T3, T2 so blocking transistor T1. The piezoelectric transducer PW is now fed with a voltage -U1 so that it expands to accelerate a printing element PD from rest towards the printing position. At this time the pulse on the line T by way of a second time controlled switching unit ZS2 causes the output signal from a gate G1 to be such that transistors T7, T6, T5 are made conductive thus also blocking transistor T1. The unit ZS1 now removes the signal on the base of transistor T4 whereupon transistors T4, T3, T2 become blocked and, with transistor T1 blocked by means of transistors T7, T6, T5, the transducer PW has no voltage applied thereto thus any vibrations caused by the rapid expansion thereof and heavily damped. Shortly before the instant at which the printing element, rebounding from the printing position, strikes the transducer PW again the outputs of unit ZS2, gates G1, G2 and amplifier V are such that transistors T7, T6, T5 remain conductive and T1 non-conductive. When the printing element PD strikes the transducer PW a signal is developed across a resistor RM by way of capactor C, resistor R and Zener diode ZD. This signal is applied to the amplifier V such that the output of gate G1 changes causing transistors T7, T6, T5 to become blocked to unblock transistor Tl whereupon the voltage +U1 is again applied to the transducer PW causing it to be contracted once more.

Title: Improvements in or relating to kinematographic apparatus
IPC: G03B1/18
Filed: 1958-08-08
Abstract: 872,090. Kinematograph apparatus. FERNSEH G.m.b.H. Aug. 8, 1958 (Aug. 10, 1957], No. 25490/58. Class 97(1)  A clamp is situated adjacent the film gate and is periodically operated to secure and release the film and a difference of air pressure is applied between the convex and concave size of the loop of film preceding said clamp such as to produce in said loop a compressive stress which is resisted by said clamp until its release whereupon said stress causes said film to move rapidly through said gate. In the form shown the film is fed, between sprockets 2 and 14, through the gate 11 and through pneumatic chambers 5, 8 and 12 each chamber consists of a wall such as 6 carrying two other parallel walls adjacent the film edges and between which the film passes. Suction is applied through the aperture 25 to produce a reduced pressure on the film in the chamber 8 so that when a clamp 10 is periodically released by the action of an eccentrically mounted roller 21 on a lever 22 the film is fed through the gate 11. The feed is assisted by the tension in the film produced by the reduced pressure in the chamber 12 caused by the application of suction to the aperture 32. Suction is also applied to an aperture 31 to produce a compressive stress on the loop of film in the antechamber 5 and after each length of film is fed from the chamber 8 to the gate a fresh length of film is fed into the chamber 8 by the release of a clamp 7 by the action of a cam 18 on a roller 19 carried on the arm 20 to which the clamp is attached. The clamp also carries a register pin engaging the film perforations. The reduced pressure in the chamber 8 may be applied continuously, in which case it is less than that applied to the chamber 5, or it may be applied intermittently through an aperture 23 in the rotating disc 24 registering periodically with the aperture 25. The reduced pressures in the chambers 8 and 12 provide components of force tending to hold the film flat at the film gate. Perforated curved members in the chamber 8 determine the maximum and minimum sizes of the film loop therein. A photoelectric device may be provided for scanning register marks on the screen or a mechanical feeler engaging the film perforations. The electrical output of the photocell may be used to correct any irregularities of feed by adjusting an optical member or, where the system includes a cathode ray tube presentation, by adjusting the scanning voltages.

Title: Frequency modulation system for transmitting colour television signals
IPC: H04N11/14
Filed: 1954-09-03
Abstract: 757,670. Television. WESTERN ELECTRIC CO., Inc. Sept. 3, 1954 [Sept. 17, 1956], No. 25625/54. Drawings to Specification. Class 40 (3). [Also in Group XL (c)] In a colour television system the complete video signal, including the luminance signal, synchronizing pulses and phase and amplitude modulated colour sub-carrier, frequency modulates the transmitted carrier, but before application to the modulator is passed through an amplitude compressor or pre-emphasis network to decrease the amplitude of the D.C. and lowfrequency luminance and synchronizing components relatively to the higher frequency subcarrier, e.g. the former may be reduced by a factor 5, while the sub-carrier and colour synchronizing signal are unattenuated. By this means the transmitted carrier occupies a narrower frequency band and colour distortion due to unequal delays in transmitting frequency components of the phase-modulated sub-carrier to a receiver is minimized. The receiver has a complementary restoring network.

Title: Improvements in the manufacture of soap compositions
IPC: C11D13/00
Filed: 1955-09-12
Abstract: A process of making a translucent soap composition, especially in bar form, includes the steps of adjusting the moisture content of molten neat soap to 16-20 per cent by weight by rapid and uniform drying, preferably in a tubular drier, and adjusting the salt content so that it is 0.5-1.0 per cent of the dried soap, the adjusted moisture and salt contents being so related that a translucent soap bar can be produced by normal compacting of the soap composition after cooling to below its solidification temperature.  Best results are obtained by saponifying a charge of 75 per cent tallow and 25 per cent coconut oil either solely with caustic soda, or with caustic soda followed by caustic potash, to yield a soap mixture which may be used in the process.  Any fat stock normally used for soap-making may, however, be used.

Filed: 1965-06-19
Abstract: 1,132,704. Fluid-pressure brakes. ATKINSON VEHICLES Ltd. 20 June, 1966 [19 June, 1965], No. 26020/65. Heading F2F. In a braking system for a mechanically propelled vehicle having at least three pairs of road wheels (e.g. two pairs of rear wheels 12, 13 and one pair of front wheels 11) and at least a dual-line air pressure braking system, in which the brakes for the rear wheels are divided into two groups with each group connected for actuation by one of the lines, a relay valve 22 is operable by either line and connected to the front brakes 11a for actuating the latter. As shown in the Figure, fluid pressure is supplied from two halves 15a, 15b of a pressure reservoir supplied with air under pressure from a compressor 14 through an unloading valve 16 and non-return valves 17a, 17b. The driver's brake pedal 17 operates simultaneously a pair of brake valves 18, 19 connected to the brakes 12a for the wheels of the foremost rear axle and 13a for the wheels of the rearmost rear axle. Both of the lines from these valves are connected through valve actuating means 21 to a relay valve 22 and the outlet from the relay valve is connected to the front wheel brakes 11a. When both dual line systems are working braking is applied to all the wheel brakes but should one of the line systems fail, for example that actuated by the brake valve 18, the brakes 12a will be inoperative but the brakes 13a for the rearmost rear axle 13 will operate and through the relay valve 22 the front wheel brakes 11a will be operated. Should the other line fail then the brakes 13a will be out of action but the brakes 12a will be operative and the brake valve through the relay valve 22 will still operate the front wheel brakes 11a Quick release connections 30, 31 may be provided for connection of a braking system of a trailer. On a vehicle having two steerable front axles and a single rear axle each line of the dual-line system can be arranged for activating the brakes of one of the front axles and the relay valve operable by either of the lines can be connected to the rear wheel brake for actuating these brakes.
