Title: Method of and means for manufacturing v-belts
IPC: B29D29/10
Filed: 1946-04-17
Abstract: 610,874. Belt gearing. WINGFOOT CORPORATION. April 17, 1946, No. 11809. Convention date, Sept. 18, 1945. [Class 80 (i)] [Also in Group XXII] In apparatus for manufacturing V-belts or the like, the belt is made on a rotatable drum 15 driven from a motor 50 through a variablespeed gear 49. The drum is made in two parts 16, 17, the cap 17 being attached to a shaft 8 rotatably connected to the piston of a pneumatic cylinder 38, and the body 16 being mounted on a sleeve 7 which is a loose fit on the shaft and is driven through gears 41, 26. The two parts 16, 17 together form a closed chamber 23 into which compressed air may be passed through a pipe 12 and passages 9, 10, 11, 11a. The belt is wound on the drum over the join 28 of the parts 16, 17 and comprises a flat fabric envelope 90, guided into place by feeding the material through a slot 91 in a guide plate 52, with a second guide plate 53 tilted back out of the way. The plate 53 is then lowered and a relatively thin gum strip 92 is guided on to the envelope 90 through a slot 93 in the plate 53, a roller 85 then being held against the material to compress the two layers together. A layer of wire 94 is then wound round the material, guided from an eyelet 64 carried in a sleeve 63 axially slidable on a spindle 62 against a spring 70 (see Fig. 3). A handle 65 slidable on the spindle 62 and carrying a serrated block 66 is depressed against a counterweight so that the block 66 engages a screw-thread 67 in the drum 15, the wire thus being guided along the drum as it rotates. An electric switch 72 carried by a member 71 movable with the block 66 is actuated to stop the drum when enough wire is wound thereon. The belt material is then recompressed by the roller 85, and a layer of flexible cushion strip 95 is applied over the wire, through the guide slot 93. The materials are again compressed, and the lateral edge portions of the envelope 90 and gum strip 92 are turned inward to cover completely the exterior of the belt which is then finished. The valve unit operating the pneumatic cylinder is then actuated to move the shaft 8 and cap 17 to the right to release the belt. If the cap will not come away easily, compressed air is passed into the chamber 23 to release the parts. The apparatus may be adjusted to receive a larger drum, by means of guideways 51, 58.

Title: Improvements relating to methods of and apparatus for applying liquids to materials
IPC: B41F31/22
Filed: 1950-05-12
Abstract: <PICT:0682417/III/1> Liquids are applied to materials by passing the liquid from a supply container to a capillary space from which it is caused to diffuse through a wall provided with capillary passages by maintaining an equalization between the pressure in the interior of the container and that at the outer surface of wall, and then is applied directly or indirectly to the material.  Referring to the drawing, supply container d is surrounded by container a so forming capillary space e to which liquid is supplied through the series of holes f and from which it diffuses through capillary passages in container a which is made of ceramic material.  Air valve g, to which a pump may be attached, regulates the equalization of pressure and the supply container is filled through closable opening h.  The containers are preferably cylinders.  The outer container may be of ceramic or metallo-ceramic material, or may be a coarse sieve or screen on which are arranged one or more layers of wire gauze, glass-fibre gauze or silk gauze and a covering layer of metal foil having a large number of uniformly distributed perforations.  Instead of the gauze the inner surface of the cylinder may be roughened while the edges of the holes at the inner surface may be widened in crater-like fashion.

Abstract: 333,597. Illingworth, S. R., and Illingworth Carbonization Co., Ltd. April 18, 1829. Charging.-In feeding coal into containers or retorts, a reciprocating member or tamping rod imparts a succession of taps or blows to the head of the charge and its stroke is automatically adjusted with the rise of the charge in the container. A charging car A carries a hopper E for charging a row of retorts D, the hopper having a discharge conduit 1, door 2, and shoot 3, leading to mouth pieces 4. Each door is held open by a latch 5 connected to a trip rod 6. A rocking beam 8 reciprocates a bar 10 to which is connected by a clutch a tamping rod 12 extending into the retort. When the bar 10 is raised, an eccentrically mounted finger 14 held in a carrier 13 attached to the rod 12 engages frictionally with the bar 10 so that the rod 12 is raised. When the bar 10 is lowered the clutch is released and rod 12 moves up the bar 10 as the retort fills up. When the retort is full the finger 14 engages with the trip lever 7 and closes the door 2. In an alternative arrangement, the rod 12 telescopes inside a hollow bar 10 and is held therein on the upward stroke by balls which are wedged to prevent relative movement between the bar and the rod. Specifications 245,190 and 248,077 are referred to.

Abstract: 1,100,571. Transistor class A or AB amplifiers. PLESSEY-U.K. Ltd. 26 March, 1965 [26 March, 1964], No. 12972/64. Heading H3T. A push pull class A or AB amplifier having the outputs of two similar stages T1, T2, T3; T1<SP>1</SP>, T2<SP>1</SP>, T3<SP>1</SP>, applied to a centre tapped load RL is arranged such that when antiphase input signals are applied to the stages in the class A operating region both stages act as linear class A amplifiers having a gain defined by negative feedback applied over each stage and in the class AB operating region the negative feedback is reduced such that the overall amplifier gain is maintained constant. As shown, for one stage, the transistors T1, T2, are biased to conduct and T3 is non-conducting so that for small input signals the output is obtained from the emitter of T2 and applied via R2 to load RL, negative feedback being applied by R1. As the input signal to A is increased in magnitude, transistor T2 will be cut off for a part of each cycle and the voltage across R2 increases until it exceeds that necessary to turn on transistor T3 which will operate in class B mode. The output current then is mostly supplied by T3 so that the overall circuit now operates in class AB mode. Negative feedback is applied via R1 as before but as the voltage across R2 remains virtually constant the feedback falls to half the value obtained with class A operation. The other stage including transistors T1<SP>1</SP>, T2<SP>1</SP>, and T3<SP>1</SP> operates in the same manner to give a push pull output across load RL which may be a loudspeaker. In an alternative circuit (Fig. 2, not shown), the transistors T1 and T1<SP>1</SP> are each replaced by a " Darlington pair " (T1T4, T1<SP>1</SP>T4<SP>1</SP>) and negative feedback is applied by connecting R1, R1<SP>1</SP> to the base electrode of T2, T2<SP>1</SP>. The circuit arrangements can be formed on a single chip of semi-conductor material.
