IPC: F16H55/56
Filed: 1953-11-26
Abstract: 802,101. Variable-speed gearing. CROFTS (ENGINEERS), Ltd. Feb. 25, 1955 [Nov. 26, 1953], No. 32848/53. Class 80 (2). One member 2 of an expanding pulley is fixed to a driving shaft, e.g. of an electric motor, and carries via a ball bearing 8 an externally screwthreaded member 7. The other pulley member 3, splined to the member 2, similarly carries, via a ball bearing 6, an internally screwthreaded member 5 screwed to the member 7. The member 5 is held against rotary movement by an anchor A and stop pin B and supports a worm 11 meshing a worm-wheel 10 fixed to the screw 7. Rotary movement of the worm 11 actuates the screws 5, 7 to move the pulley member 3 axially to vary the effective diameter of the cone pulley 28. The worm is rotated by a flexible shaft 12 connected to a band wheel 24 by a shaft 17 and gears 15, 16. The shaft 17 is mounted in a base-plate 22 supporting the motor 20, is screw-threaded, and carries a nut 18 having a slot engaged by a lug 21 on the motor base 19. The latter is guided for sliding movement on guides 23 which are inclined to the axis of the motor shaft. When it is desired to change the speed of the pulley driven by the pulley 2, 3, the hand wheel 24 is rotated to vary the expanding pulley 2, 3 and, at the same time, the motor and the expanding pulley mounting is moved bodily to keep the tension of the V-belt 28 at the correct value. The worm and wormwheel 10, 11 may be replaced by other forms of gearing. The motor shaft may carry two expanding pulleys which are adjusted simultaneously. The shaft 17 may be operated electrically or automatically.

Abstract: 843,667. Holders for note pads and writing instruments. HARNWELL, J. P., and DIXON, T. C. Oct. 22, 1958 [Oct. 22, 1957], No. 32870/57. Classes 16 and 146(1). A holder for a note or scribbling pad and a pencil or pen comprises a base board, clamp means for holding a pad on the base and a device simulating a bird, animal or human figure mounted on the base or on the clamp means and having means for holding a pencil or pen, the or some of the components of the figure being of such resilient construction that the pencil or pen may be used to write upon the pad without detachment from the figure. The base board 10 is of wood, hardboard or plastic and may be roughened or provided with antislipping material on its underside. A pad 11 is gripped by a clamping plate 12 formed of the same material as the base board. A bird-like figure having legs 14 and a neck 16 formed of helically coiled spring wire is mounted on top of the plate 12, the legs 14 being secured adjacent to their lower ends in "feet" 13. The lower ends of the legs 14 pass through holes in the plate 12 and are fastened to the base board by screws 21 so that the plate 12 at one side of a fulcrum 22 secured to the base board is spring- urged downwards to clamp the pad 11 to the base 10. Downward pressure on the plate 12 at the other side of the fulcrum releases the pad. The bird's "head" 17 has a transverse passage in which a pencil 19 is frictionally retained. Owing to the flexibility of the members 14, 16 the pencil 19 can be used for writing on the pad 11 without removing it from the passage in the head 17.

Filed: 1959-10-01
Abstract: 933,646. Sorting digital data. HUGHES AIRCRAFT CO. Oct. 1, 1959 [Nov. 3, 1958], No. 33375/59. Class 106 (1). Binary numbers in a number of " delay-line " type stores (as shown in Fig. 1, the delay-lines are lengths of magnetic tape between write and read heads W and R) are sorted into numerical order by routing numbers, one from each store, simultaneously into a unit 32 which sorts them into increasing numerical order on output lines u-z, and passing them back to the stores under control of a switching unit 41 and counter 44 which switch the connections of u-z with writing stations I-VI so that u (the lowest number output) is connected to I, v to II &c. for the first number period (the start of each period being indicated by a signal from head 12); u to II, v to III . . . and z to I for the next; u to III, v to IV . . . and z to II for the-next two; u to IV, v to V . . . and z to III for the next four; u to V . . . and z to IV for the next eight ; and finally u to VI . . . and z to V for the next sixteen. In the embodiment shown, stations 14-19 store respectively 1, 1, 2, 4, 8 and 16 numbers so that the connections of u to each of I-VI is maintained for a number of word periods equal to the number of words in the preceding store; it is stated that the stores may be of any lengths provided that this rule is obeyed. A five-stage counter 44 and " and " gates 46-56 provide the switching signals for the switching matrix 41 (Fig. 2, not shown). A signal is produced on line 70 whenever an interchange of numbers in the 14 and 15 positions is effected when these are compared in unit 32 if two cycles of operations are completed without such a signal (indicating that sorting has been completed) then a flip flop 73 is set to open gates 34 instead of 30, the stores being then effectively joined into a single loop. The setting of 73 is effected by the output of an " and " gate 77, which receives two inputs from a 3-state counter 76 when this counter has received two pulses from gate 75. Gate 75 is enabled to pass word pulses from 12 when a cycle has been completed without the resetting of 74 by a signal on the line 70. The sorter 32 (Fig. 3, not shown) is built up from a number of units which are the subject of Specification 933,648.

Title: Distillation and analysis apparatus
IPC: G01N25/14
Filed: 1964-08-18
Abstract: Liquids are submitted to quantitative analysis with respect to a relatively volatile component of the liquid, e.g. a dissolved gas, using an apparatus comprising a heater 12 through which the liquid is passed, a separator 24 for separating gas from the heated liquid, and a chamber 44 for absorbing the separated gas in a stream of absorption liquid introduced into the chamber through inlet 50 and removed through outlet 52, the level of liquid in chamber 44 being maintained constant by tube 62.  The solution of gas so obtained is free from interfering substances, and is submitted to analysis.  The separator 24 is provided with baffles 34 which act to remove liquid droplets from the gas.  In order to carry out a colorimetric determination of cyanide in a stream of industrial waste liquid, part of the liquid is pumped by compressible pump tube 16 into conduit 14, and a solution of magnesium chloride in hydrochloric acid is introduced into conduit 14 by another pump tube (not shown).  Air is introduced into conduit 14 via pump tube 17.  The mixture in conduit 14 flows through coil 20 where it is heated for several minutes at 95 DEG C., whereupon hydrogen cyanide is evolved.  The HCN gas is separated in separator 24, and flows into chamber 44, where the HCN is absorbed in a stream of water pumped in through inlet 50.  Waste liquid is withdrawn from the bottom of separator 24 and through anti-surge coil 42 by means of pump tube 38.  The aqueous solution of HCN formed in chamber 44 is drawn through tube 58 into pump tube 60 and then flows into tube 76 where it is treated with bromine water introduced by pump tube 70.  Cyanogen bromide is formed in coil 78; and the aqueous solution is then treated with sodium arsenite to remove excess bromine.  The liquid leaving coil 82 enters a vented reservoir (not shown) from which an aliquot stream is taken and mixed with a solution of pyridine and benzidine in dilute hydrochloric acid.  After the colour has developed the liquid is passed into the flow cell of a colorimeter.  The determination of fluorides and phenols is mentioned.
