Filed: 1971-10-18
Abstract: 1361599 Tobacco smoke filters BRITISH-AMERICAN TOBACCO CO Ltd 18 Oct 1971 [2 Nov 1970] 51931/70 Heading A2C [Also in Division B5] Tobacco smoke filters are produced by apparatus comprising a device for extruding a continuous rod of foamed plastics material, a haul-off device having an endless belt or tape for engaging round a portion of the periphery of the rod as it leaves the extruder, the belt or tape passing through at least the lower part of a garniture of a filter-rod making machine, and a device for cutting the rod into required lengths as it leaves the haul-off device. The extruder and cut-off devices may be of conventional type, and the haul-off device, in one form, consists of a belt 1 which has a concave outer surface passing over pulleys carried by adjustable bearing plates 2, 3 and mounted over the lower part (not shown) of the garniture where the rod 13 is temporarily wrapped in the usual tape 12. The belt may be of rubber faced with plastics foam material, e.g. polyurethane or polyethylene, or it may be made from rubber &c tubing, or it may be in the form of a toothed belt positively engaging the pulleys or sprockets and faced on its outer surface with segments of foamed plastics material formed on their outer surfaces with longitudinal recesses of nearly semi-circular cross-section. The belt is driven through variable-speed gearing 19 which may be controlled by a servomotor so that the haul-off speed corresponds to the rate of delivery of extrudate. For example, the extruded rod after passing through a cooling tube or over a wire mesh belt and then through the haul-off device may pass through a circumference-monitoring gauge controlling the variable-speed gear before it enters the cut-off device. In a modification, the haul-off belt is constituted by the garniture tape which is made wider than usual in a filterrod garniture, and the upper part of the garniture consists of two adjustable plates which are formed so that the tape is wrapped around substantially the whole of the circumference of the rod. The apparatus may be used with rod made of various materials such as foamed polyethylene, polypropylene, nylon or cellulose acetate; it may also be used to wrap the rod in a paper strip, and it may be used with rod of other than solid, circular cross-section.

In a drawer type vending machine, rapid adjusting means comprising coin separators 25, packing pieces 35, and coin replacement pieces 34 allow any combination of two coins, or alternatively a single coin, to be accepted in a coin holder 23 adapted both to receive coins on edge in the same plane and to hold said coins in the path of locking means for releasing a drawer. Coins C are received edge to edge in the holder 23 which is mounted on a bar 29. Attempts to open a drawer cause cam 29a to move the bar 29 (and hence the coins) in a plane perpendicular to the planes of the coins so as to move rollers 32 on arms 31 apart, thus releasing pawls 30 from the bar. If no coins, or coins of insufficient diameter, are present in the holder 23, the rollers pass through cut outs in the holder. To adjust the mechanism for different coins, packing pieces 35 may be inserted to accommodate smaller coins (Fig. 7) (not shown). A coin separator 25 is also used to obtain required spacing of coins (Figs. 7 and 12, not shown), and a coin replacement piece (Fig. 12) can be used if only one coin is required for the purchase.  Excess coins are diverted via flap (39) (Fig. 1, not shown) and coins can be returned to the customer by pressing a button to remove a coin support 37 (Figs. 7 and 12), the coins falling down a shoot (38) (Fig. I, not shown).

Abstract: 1,198,867. Compressed gas container discharge device. T. FUJIMOTO. 5 Dec., 1967 [8 Dec., 1966; 17 May, 1967; 31 Aug., 1967; 24 Oct., 1967; 27 Oct., 1967; 1 Nov., 1967 (2)], No. 55236/67. Heading F4P. Relative movement between a compressed gas storage cylinder 13, Fig. 1, and a seal cutter 12 is effected by a biasing spring 4 normally restrained by means 7 under tension which on contact with water breaks and allows the spring to extend and thus move the cutter relative to the cylinder seal 14 to effect gas discharge. The tensioned restraining means 7 may comprise a paper cylinder tied at its ends to discs 5, 6 against which opposite ends of spring 4 bear, and water is admitted through inlets 16 of a casing 1 divided by a cutter-holding piston 9 into water and gas spaces; the latter space being connected by a duct 2 to an article to be inflated, e.g. a lifejacket. The cutter may be moved manually by pulling a cord 19 resulting in rocking a lever 17 about a shaft 18 thereby lifting both discs 6, 7 and the cutter piston 9. In a modification the cylinder 13, Fig. 3, is moved towards the cutter 12, and packing rings 28 on the cylinder divide the casing 1 into water and gas spaces. In a further modification the spring 4, Figs. 7A, 7B is restrained by a bar 48 passing between the arms of a cutter pin 44 projecting downwardly from disc 6; the bar being seated against the underside of a casing 46 and the arms being tied at their ends by paper tape 45 which when wetted collapses and allows casing 46 to push the cylinder against the cutter 12.

Title: Anti-skid brake control system

IPC: B60T8/17
Filed: 1965-12-30
Abstract: 1,091,308. Automatic deceleration control. CRANE CO. Dec.30, 1965, No.55295/65. Heading G3R. [Also in Division F2] The rate of deceleration during landing of a multi-wheeled aircraft is regulated to prevent skidding by brake-control, the speed of wheel W7 being detected by transducer coil 22 associated with frequency-sensing circuit 17, 18, and rectifying and wave-shaping net 28, 30, 26, whereby the square waveform signal developed at terminal 34 has a frequency proportional to wheel-speed. A series of pulses of corresponding frequency is produced at terminal 40 by differentiation by capacitor 38 and resistor 42 which are connected to transistor amplifier 36. These pulses are integrated by circuit components 46, 48, 50, so that the potential at terminal 47 decreases with decrease of frequency. The current passing through transistor 52 decreases with reduced speed permitting partial discharge of capacitors 58, 59, to render transistor 64 conductive, the bias potential established by diodes 61, 62, representing the maximum deceleration rate. Transistors 68, 70, then conduct to energize coil 72 of a pilot valve for relaxing the brake. The pilot valve by-passes fluid under pressure around the brake cylinder in proportion to the strength of the applied signal. In the absence of a signal to coil 72, the braking effort is controlled by adjustment of a brake-pedal valve. Brake application before the wheels are loaded is prevented by a signal through rectifier 76 and switch 100. The first wheel to roll supplies potential to a central memory unit comprising capacitor 80 so that, if one or more wheels are not loaded after the switch 100 is operated, locked wheel protection is still provided. The potential across capacitor 80 is supplied by the fastest wheel. If wheel-lock occurs, the signal at terminal 34 is removed, and capacitor 89 discharges whereby capacitor 80 renders transistor 90 conductive. The resultant potential-drop across resistor 77 is amplified by transistors 81, 70, to energize coil 72 and remove the brake. After deceleration ceases, the brake pressure is prevented from returning to the level which caused the incipient skidding. For this purpose, each time a valve-controlling signal is developed by transistor 70, the charge on capacitors 101, 102, is increased, As the control signal decreases transistor 98 conducts to maintain energization of coil 72. Hence the brake pressure continues to be relaxed to an extent dependent upon the rate control signal.

Abstract: 1425324 Wedge-type brake actuators GIRLING Ltd 26 Nov 1973 [7 Dec 1972] 56475/72 Addition to 1141790 Heading F2E In a wedge-type brake actuator comprising a wedge member 7 located in a housing 1 for applying, e.g. internal shoes against a vehicle brake drum, means, e.g. tappets 4, displaceable by the wedge member 7 and presenting complementary inclined surfaces 11, at least one roller 9 interposed between each surface 11  and the co-operating surface 10 of the wedge member, and a cage 12 in which the rollers are retained and guided, the cage 12 is provided on opposite sides of the wedge member with roller-spindle-receiving apertures 14, 15, Fig. 2, of different outline which are divergent with respect to the direction of movement of the wedge member 7 when displacing the tappets 4. The shaft 6 extends through an opening 19 (Fig. 2, an underneath view), in the base 17 of the generally U-shaped cage, and the cage is slidably guided in the bore 5 by end flanges 18. The aperture at one side of one limb of the cage has the same shape as the aperture opposite to it in the other limb of the cage. Thus, aperture 14, Fig. 2 (which shows the limb of the cage opposite to that shown in Fig. 1) is parallel-sided and open at the end, while aperture 15 is pear-shaped and closed. Where, as shown, one tappet is inextensible while the other is automatically adjustable in length for wear-adjustment, the inextensible tappet is lengthened and slotted at 24 to act as lateral guide means for the cage and wedge-member assembly; where both tappets are inextensible, both may be lengthened and slotted. Where the brake is of the two-leading-shoe type, in operation, with drum rotation clockwise; (Fig. 1), the left-hand tappet remains stationary while the right-hand one moves outwards. Thus the cage tilts in its own plane to follow movement of wedge member 7, so spindles 16 of left-hand roller 9 tend to ride along the upper edges of apertures 15, while spindles 16 of the other roller follow the line of apertures 14.
