Title: Improvements in or relating to tubing for use in electric lamps more particularly gaseous electric discharge lamps
IPC: H01J61/02
Filed: 1936-08-17
Abstract: 480,315. Glass tubes. HUTAFF, jun., G., and NORRIS, H. B. Aug. 17, 1936, No. 22593. [Class 56] [Also in Groups XL and-XI] Glass tubing forming the envelopes of electric lamps such as neon or mercury discharge tubes or incandescent lamps is circular in cross-section on its external surface and is formed within its thickness with means extending longitudinally of the tubing to refract the light into one or more beams. Cylindrical lenses are inserted in the tubing at one or more points around it, as at 5, Fig. 1. In other modifications, a mirror 7<1>, Fig. 5, is embedded in the tubing and encloses a lens formed by the glass 12 between the mirror and the internal surface. The mirror may be parabolic and may extend to the outer surface 6<1> and reflects simlight when the tube is used as a sign.

Title: Electormagnetically controlles seat belt retractor mechanism
IPC: B60R22/48
Filed: 1975-05-23
Abstract: 1464709 Electromagnetically controlled seat belt retractor FORD MOTOR CO Ltd 23 May 1975 [10 June 1974] 22613/75 Heading A3V An electromagnetically controlled seat belt retractor 10 has a reel spring-loaded to retract a belt coupled to it. A cam 16 is journalled concentrically with the reel, is biassed by spring washer 17 into frictional engagement with it and capable of limited rotation with it. Cam lobe 18 lies in the path of locking bar 15 when cam 16 is in the Figure 1 position as occurs during retraction or in the fully retracted condition. Protracting the belt causes cam 16 to rotate clockwise to the Figure 2 position (not shown) where cam lobe 19 lies in the path of bar 15. Movement of cam 16 is limited by movement of bar 22 on the cam moving in slot 21 in the retractor frame side wall 13 to contact solenoid 27. Release of the pulling force on the belt reverses the reel and drags cam 16 back to the Figure 1 position during which movement bar 15 engages a toothed ratchet wheel fixed to the reel preventing further belt protraction. If however the solenoid is energised, e.g. when the seat is occupied and the transmission lever is at neutral or park position, bar 22 is held against it and lobe 19 prevents movement of bar 15 into reel locking position allowing the reel to rotate in protraction or retraction directions.

Filed: 1944-11-15
Abstract: 596,862. Making tubes. GRISCOMRUSSELL CO. Nov. 15, 1944, No. 22618. Convention date, Jan. 26. [Classes 83 (ii) and 83 (iv)] Rolling helical grooves.-In a method of grooving a malleable article, the surface is furrowed by a ploughing action effected by grooving rollers having a different linear speed from the malleable surface, the metal being displaced in two directions. As applied to the construction of fin-tubing, the tube 1 is supported in a lathe and a grooving-roll 6 is mounted on the crossslide 11 of the saddle, the saddle being traversed in known manner. The grooving-roll is in the form of a disc, the periphery of which is bevelled and scalloped as at 23 and 24, the scallops being staggered. The roll is driven at a slower peripheral speed than that of the tube by a knurled disc 44, adjacent to and independent of the grooving roll, through contact with the tube 1, the drive being transmitted to the roll through reduction gearing wherein a floating gear 59 is employed in order to allow for relative lateral movement between the knurled disc and grooving-roll when the disc is independently moved further into engagement with the tube by an adjusting-screw 60 forcing the bearing- block 48 towards the tube.. The tube is supported by backing-rolls 18. The grooving-roll assembly is mounted on a rotatably adjustable plate 32 so that the roll may conform to the helix-angle of the groove, and is secured to the main support 10 by screws 33 projecting through arcuate slots. The helical groove is formed by the scallops displacing the metal to either side of the groove, as shown at 3 in Fig. 10, without detaching it from the body. Caulking.-Strip 4 is wound into the groove and the displaced metal swaged back against the strip to secure it.

Abstract: 1,103,954. Photo-electric slnb detectors. S. PEYER. May 27, 1965 [May 28, 1964], No. 22643/65. Heading G1A. [Also in Divisions D1 and H3] In a photo-electric yarn cleaner the effects of gradual changes in illumination at the photo-cell are eliminated by adjusting through a delay circuit a variable impedance in the signal circuit in accordance with deviations of a voltage in the signal circuit from a reference voltage. The signal from photo-cell 12 is fed by a common base connected transistor T1 to an amplifier T2. Pulses above a threshold set by P2 corresponding to slubs are passed by the diode to an amplifier T4, T5 the output of which operates a relay or solenoid 30 of a yarn cutter or slub counter. A proportion of the output from T2 is picked off by a potentiometer P1 and applied to the base of a transistor T3. A fixed voltage -U1 is applied to the emitter of T3 and variations in the collector current due to slow changes in the output of T2 vary the heating of a negative temperature coefficient resistor R2. Changes in the output current of the photo-cell are thus compensated by varying the resistance through which the current flows to develop the base voltage for T2. The resistor R2 has a response time of about 15 seconds so slub signals are unaffected by its action. A plurality of yarn cleaners may be connected at 46, 47, 48 and have their sensitivity simultaneously controlled by the potentiometer P2. The potentiometer P1 may be fixed.

Abstract: 461,745. Vehicle brakes. BEUSCH, C. Aug. 19, 1935, No. 23251. [Class 103 (i)] In a brake system for vehicles in which one back wheel only is primarily braked, the braking effect of this wheel is transmitted to the brakes on the other three wheels by a transmission system arranged so that the braking effect on the other three wheels is less than that on the one back wheel in order to avoid locking of the three secondary wheels if the primary wheel locks. The shoes 11 of the brake of the primarily braked rear wheel are mounted on a lever 13 which can rock to a limited extent to transmit the turning effort of this wheel by hydraulic transmission 17 to the brakes 23 on the other three wheels. The turning moment imparted to the lever 13 by the shoes 11 has a smaller arm than the moment produced by the reaction at the piston 15 so that this arrangement produces a " stepdown " in the transmission of the braking force from the primarily to the secondarily braked wheels. The ratio of the cross-section of the pistons at the primarily and secondarily braked wheels may be varied for this purpose. The shoes 11 may be operated by another hydraulic cylinder in addition to cylinder 9 operated by pedal 1, this additional cylinder being operated by a servomotor and being supplied with fluid from the conduit 17. The transmission may be mechanical. Specification 296,260, [Class 103 (i)], is referred to.
