IPC: B60R25/021
Filed: 1969-06-26
Abstract: 1283107 Anti-shift devices WASO Ltd 24 April 1970 [26 June 1969] 32231/69 Heading B7J [Also in Division E2] A fastening mechanism comprises a body 1, Fig. 1, a rotatable and axially movable cylinder 3, a rotatable barrel 2 which receives the cylinder 3 therein, a cam 11 which is rotated by the barrel 2 to move a bolt 5, a spring 27 which urges the bolt 5 towards a fastening condition and a movable sleeve 24 which is urged by a spring 26 into a slot 19, Fig. 3A, formed in the bolt 5 so as to retain the latter in an unfastening condition. The body 1 receives, in addition to the barrel 2, a rotary electrical switch 4 which controls the ignition and starting circuits of a motor vehicle, for example, and is provided with a bracket 6 for facilitating the clamping of the body to a steering column (not shown). The cylinder 3 has an outwardly-directed flange 8 which is slidable in a stepped portion 9 of the barrel 2. The cam 11 receives a spigot 13 of the cylinder 3, the spigot carries a drive-pin 14 which extends through the cam 11 and is keyed thereto at 15, and the cam 11 is engaged by an extension 18 of the bolt 5. The drive pin 14 passes through the slot 19, Fig. 3A, in the bolt 5 and through a bore 21, Fig. 1, in the body 1 and is attached to the switch 4. The sleeve 24 is slidably mounted on the drive-pin 14 and has a head 25 which is received in an enlargement 20, Fig. 3A, of the slot 19. The bolt 5 is provided with a protuberance 28, Fig. 1, which locates the spring 27. When a key 30, Fig. 2, is introduced into the cylinder 3 and pressure is exerted in the direction of the arrow A, both the cylinder and the cam 11 are moved towards the bolt 5 as shown in Fig. 3B and the spring 26 is compressed. As the slot 19, Fig. 3A, is not sufficiently wide to allow passage of the head 25 of the sleeve 24 therethrough the latter cannot slide. The rotation of the key however causes rotation of the spigot 13, of the cam 11, of the drive pin 14 and of the electrical switch 4, and a part-circular portion of the cam engages a protrusion 18, Fig. 1, of the bolt 5 which is moved against the spring 27 and casues a movement of the slot 19, Fig. 3A, with respect to the sleeve 24 so that the head 25 thereof can enter the enlargement 20, Fig. 3A, to prevent the locking bolt from being moved by its spring 27 into the fastening condition. The rotation of the switch 4 to its closed position effects ignition.

Title: Improvements in or relating to carburettors for use with internal combustion engines
IPC: F02M19/12
Filed: 1931-11-23
Abstract: 392,929. Spray carburetters. GRACE, C. J., Cleveland House, City Road, London. Nov. 23, 1931, No. 32416. [Class 7 (iii).] Provided in the main air inlet passage of a carburetter is an unbalanced valve which is opened by suction, the degree of opening being limited by an adjustable stop. An air valve 1 is eccentrically mounted on a spindle 2 and carries a pin 5 which traverses a slot 3 in a throttle lever 4. The spindle also carries levers 7 having pins 8 which engage the lower portion of a weighted saddle member 9. A needle valve 13 carried by the member 9 regulates the fuel supply and, when the throttle valve is closed, a spring 20 engages the head of a spring- biased needle valve 18 to cut off the supply. The valve 18 may be closed by hand irrespective of the position of the throttle valve as and when required and, if desired, the valve 13 may also perform the function of the valve 18. Air enters through orifices 23 when the member 9 is raised. The valve 13 traverses a nozzle 24, the height of which is adjusted either by a screw 25 movable in a slot 26 or by a Bowden cable. To damp the movements of the throttle valve 1, a friction damper may be arranged on its spindle or the spindle may be connected to a piston which slides in a cylinder in communication above the valve with the induction pipe so that the damping effect produced will vary with the engine suction. Specification 144,363, [Class 7 (iii), Internal-combustion engines, Carburetting-apparatus &c. for], is referred to.

Title: Control system for doors or the like
IPC: E05F15/50
Filed: 1934-11-12
Abstract: 428,821. Door-operating appliances. COMPAGNIE INTERNATIONALE DES FREINS AUTOMATIQUES SOC. ANON., 70, Rue Louvrex, Liege, Belgium. Nov. 12, 1934, No. 32599. Convention date, Nov. 10, 1933. [Class 65 (i)] A power-operated door is locked hydraulically, against manual operation, at one end of its movement by a piston in a locking cylinder controlled by a valve which is operated by the taking-up or opening of play provided in the connection between the operating means and the door. In the arrangement shown, the door is operated by a rod 5 attached to a piston 6 having arms 5<a> to provide a lostmotion connection with the rod 2<a> of a piston 2 which is moved to the left, to open the door, by connection to a source of vacuum through pipe 3 and is returned by a spring 4, to close the door, when the connection 3 is cut off. The cylinder in which the piston 6 works is filled with liquid, any loss being made up from a reservoir 12 ; the piston is consequently prevented from moving to the left unless a valve 11 in it is opened to allow the passage of liquid. This valve is opened by the movement of rod 2<a> taking up the play in the connection with arms 5<a> at the commencement of the opening stroke of the mechanism, but cannot be opened by pushing the rod 5, so that the door is locked closed except against opening by the piston 2; the valve 11 opens automatically during the closing movement against a spring 7, which normally maintains the parts 2<a>, 5 in the relative positions shown. In a modification, the valve 11 is dispensed with, the spring 7 being arranged in an equivalent manner connecting the parts 2<a>, 6, and the reservoir 12 is connected to the cylinder to the left of the piston 6, so that during the opening of the door the piston forces liquid into the reservoir and compresses air therein to provide the power for the closing movement, the spring 4 not being required. The pistonrod 2<a> carries a piston valve which closes the passage to the reservoir when the door is closed and this locks the door until the pistonrod moves in taking up the play between it and piston 6. A non-return valve is provided to allow passage of liquid under pressure from the reservoir to the cylinder when the pistonvalve is closed, in order to complete the closing movement of the door.

Title: Improvements in and relating to machines for wrapping canisters with lid-sealing-tape, wrapping material and the like
IPC: B65B11/04
Filed: 1926-12-24
Abstract: 286,034. Wall, W. H., and Wander, Ltd., A. Dec. 24, 1926. Labelling; affixing tape and like strips.- Adhesive tape for sealing the lids of cans, or other adhesive labelling material for cans is progressively fed to a can which is rotated about a stationary axis, the tape &c. being automatically cut into lengths by cam-actuated knives in its passage round the feeding-drum. Cans 7, Fig. 1, are fed from a shoot 8 to a runway, the foremost can 18 being frictionally rotated against rollers 10, 11 by an endless belt 19 carried on wheels 20. The roller 11 is carried by an arm which is lifted by a cam for the discharge of a labelled can. A pressure roller 27, mounted on an .adjustable arm 28, regulates the tension of the belt 19, and pressure rollers 24, 25 carried in guides 26, regulate the grip of the belt 19 on the can. The tape is fed to the can 18 from a supply reel 37 by a drum 30 which is intermittently rotated, by a quadrant 32, a third of a revolution at a time. In the dwell periods the tape drawn on to the drum is severed by knives 39 mounted on a block 40 sliding in a guide 41, the knives being advanced into a notch 44 in the drum by a cam 45 on a cam-shaft 17, and closed on the tape to cut it by a cam 46, Fig. 4. So that the can 18 shall be free to rotate during the labelling operation, means are provided for momentarily checking the forward movement of the stream of cans 7, and comprise a free roller 53, and a roller 54 carried by an arm which is camactuated to rise after the roller 11, so that a can is fed forward after the labelled can has been ejected by the belt 19, the roller 54 dropping again to arrest the stream of canisters 7. Suction holes are provided on the periphery of the drum 30 to maintain the alignment of the adhesive tape. Pivoted fingers 58, Fig. 6, are spring-actuated to bear at their ends 60 on the abutting ends of the cut tape on the drum, a stationary cam-plate 61 lifting the fingers to release the end of the tape for attachment to the can, and maintaining the fingers lifted until they can again close on the uncut length of tape on the drum. The run-way is formed with a valley 63 near the drum 30, Fig. 5, and to ensure effective contact between the leading edge of the tape on the drum and the can, a small section 70 of the drum periphery is made outwardly yieddable, being mounted on a spring-pressed plunger 71, the section 70 being normally held down on its seating by the pressure of the fingers 58. A leather &c. mask closes the suction holes in the drum between the two positions where no tape overlies the drum. The supply reel 37 is held in position on a spindle 38 by a U-shaped hinged arm 75.

Title: Improvements in or relating to phase or frequency modulation
IPC: H03C3/00
Filed: 1939-12-22
Abstract: 534,955. Phase and frequency modulation. WEIGHTON, D., and PYE, Ltd. Dec. 22, 1939, No. 32760. [Class 40 (v)] A system of frequency or phase modulation comprises the first step of beating a master controlled oscillator A with an oscillator B which is frequency modulated by the signal. The resulting summation frequencies are passed through a phase-changing line or network D which gives a phase shift linearly proportional to the frequency, and the output is caused to beat again with the frequency-modulated wave from B. The difference frequency is selected and is passed as a phase-modulated wave, through frequency multipliers if desired, to the load. The phase-shifting network D may alternatively be connected between B and C, or between B and E. If suitable distortion is applied to the initial signal before its application to the frequencymodulated oscillator B, the output obtained from F may be a frequency-modulated wave.

Title: Improvements in or relating to assemblies of driving and driven elements
IPC: F02B33/00
Filed: 1939-12-22
Abstract: 536,844. Variable - speed gearing. UNITED AIRCRAFT CORPORATION. Dec. 22, 1939, No. 32784. Convention date, Feb. 3. [Class 80 (ii)] [Also in Group XXVII] In synchronizing- means for a variablespeed gear for driving an accessory of an internal-combustion engine such as a super-charger the driven member is speeded up, on changing from low to high gear, by a turbine driven from the engine exhaust. An extension 20 of the motor-shaft drives through a low-speed gear-train 30, 34, or a high speed train 32, 36, a lay shaft 38, which is connected by gears 44, 46 to the shaft 28 of the impeller 26 of the super-charger. The driving- gears 30, 32 of the two trains are connected to the shaft 20 through oppositely acting one-way friction-clutches. Either of the gears can be locked to the shaft, so as to give a two-way drive, by a positive dog-clutch operated by a manual control 78. The impeller-shaft can be driven through a one-way clutch 76 by a turbine 70 operated from the engine exhaust under the control of a hand-operated valve 80. In changing from low to high speed, the turbine is put in action to drive the impeller shaft at a speed above that of the high-speed train. The gear 32 thus becomes locked to its shaft through the one-way clutch, and the positive clutch may be put in without clashing. The turbine may then be put out of action, and the impeller will be driven by the high-speed train, the gear 30 of the low-speed train overrunning the shaft 20. In changing to low speed, the turbine is put in action to take the load off the positive clutch, which is then put out. The turbine is then deenergized, and the impeller slows down until the drive is picked up by the low gear. By the use of a larger turbine than is necessary for synchronizing the gears, the turbine may be kept in action for longer periods, and employed to return a certain amount of exhaust-gas energy back to the engine either by overdriving the super-charger or by acting on the shaft 20 through the low-speed train, the gear 30 being positively locked to the shaft.

Abstract: 1,104,957. Ignition generators. FORD MOTOR CO. Ltd. 2 Aug., 1965 [12 Oct., 1964], No. 32926/65. Heading H2A. [Also in Division F1] The distributer housing of an internal combustion engine includes a permanent magnet electrical generator whose output is connected to a transistor circuit for providing the required H.T. supply to the sparking plugs, Fig. 1 (not shown). The generator has an annular permanent magnet 123, of barium titanate, secured between plates 131, 132 together with an annular magnetic shunt 124 and annular output coil 63 which is enclosed in plastics bobbin 126. The outer ends of plates 131, 132 are notched and bent to provide spaced apart, radially aligned polepieces 141, 142, the polepieces 141 being peripherally shorter than inner polepieces 142. Rotor 145, of magnetic material has poles 147 bent down to lie between the polepieces 141, 142 and these poles are further twisted so that the leading edge lies close to polepieces 142 and the trailing edge adjacent to polepieces 141, Fig. 5 (not shown). An air gap 148 is provided between the annular shunt 124 and plate 132 so that the flux linking output coil 63 changes cyclically when poles 147 of the rotor move in and out of alignment with stator polepieces 141, 142 thus generating a time varying voltage which is applied to the circuit of Fig. 1, to produce the required H.T. supply to the sparking plugs. The number of cooperating poles and polepieces is equal to the number of cylinders in the I.C. engine. Post 161 which is rigidly attached to rotor 145 carries a normal distributer arm 171, and is angularly movable relative to the drive shaft 115 by a weight operated, centrifugal advance mechanism, Fig. 2 and 3 (not shown). The stator structure 122 is mounted on bushing 134 and can be angularly displaced by a standard vacuum advance mechanism 177, Fig. 2 (not shown).
