Title: Improvements in self-acting mules
IPC: D01H3/08
Filed: 1919-05-12
Abstract: 141,207. Lodge, L., Darbyshire, W. C., and Lodge, A. W. May 12, 1919. Mules.-Means under the control of the carriage for regulating the delivery of yarn by the front rollers comprises a cord or chain actuated by the carriage and adapted through gearing to rotate the rollers during the first portion of the outward run, the length of the period of delivery being adjustable. At the requisite moment, means operated by the carriage transfers the drive from the rollers, which remain stationary during the remainder of the outward run. The speed of the carriage remains unaffected throughout. The chain or cord d is attached to the headstock at e and passes round guide-pulleys b, g, h and over a sprocket-wheel i combined with a ratchet-wheel j adapted to be locked for movement in one clirection with a larger wheel l on the same shaft m, which is suitably supported over the headstock. The chain then passes over guide-rollers u, t and a sprocket-wheel p, which is mounted on a shaft q connected by gearing with the front roller shaft o. The chain &c. passes thence over a guide-pulley c on the carriage, a pulley n, and the wheel l, the free end carrying a weight v. The pulley n can be locked against rotation by a pawl x controlled by a rod y which can be moved longitudinally by the engagement of the carriage with a lug z adjustable along the rod. When the pulley n is locked, the cord paid out by the pulley b is stated to be drawn round the pulleys i, p and to drive the rollers. When the pawl x is released by the carriage and the pulley n can rotate, the drive is stated to be transferred to the wheel l, the rotation of the rollers ceasing. The slack in the cord or chain paid out bv the carriage is taken up by the driving of the wheel i, and the movement of the pulley u, which is arranged to fall in a slot in the headstock. The cord is taken up again during the inward run of the carriage.

Title: Improvements in variable condensers
IPC: H01G5/38
Filed: 1925-05-07
Abstract: 256,324. Aspden, R. L. May 7, 1925. Condensers, variable, have the fixed movable plates formed with gaps or slots and tongues so co-operating that they come into alignment more than once in a half turn so that changes from maximum to minimum capacity are correspondingly frequent. Fig. 1 shows the improved condenser f coupled with an ordinary condenser e for tuning two circuits from one control member, a, e being fixed, and b, d moving, plates. As shown in Figs. 3 and 4, the plates c have tongues g and the plates d have slots h, 12 in number, but this number may be varied to suit requirements. The -hole i through the fixed plates is larger than the centre j of the moving plates, and the diameter of the slots between the tongues g is larger than the overall diameter of the moving plates. The condenser e is actuated by a spindle m and. the latter is geared through gearing n, o, p, q to the sleeve r which carries the plates of condenser f, the gearing being speed-increasing and made, for instance, of vulcanite or like insulation. As shown, one turn of the plates c changes the capacity of condenser f from minimum to maximum twelve times and, with a gear ratio of 1 : 12, for a half turn of condenser e the condenser f will change in capacity from minimum to maximum 72 times, thus making it possible to get approximately accurate tuning of two condensers by operating one control which may be on the spindle m or sleeve r. A knob s and finger t moving over a scale are fitted on the sleeve, and instead of plates c, d coaxial tubes with longitudinal slots and tongues may be used. According to the Provisional Specification, the fixed and moving elements are subdivided into a number of parts which are connected together or insulated from one another according to the purpose for which the condenser is designed. It is also stated that the moving elements, three in number and in the form of discs, have 45 teeth cut around their periphery and are located on a square shaft with the teeth in line. The fixed elements are five in number and also have 45 teeth on their periphery.

Abstract: 1,110,552. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 18 March, 1966 [22 March, 1965], No. 11963/65. Heading G4H. [Also in Division H3] In an analogue-to-digital converter of the kind described in Specification 1,046,792 in which the input signal having a damped oscillation superimposed upon it is applied to a group of series-connected bi-stable threshold devices which switch in succession and subtract a weighted signal the characteristic of the bi-stable elements is modified so as to have a portion BC, Fig. 2, of flatter slope. This improves the operating characteristics. In the form of Fig. 3A, for quantizing a current, generator G produces the input signal and damped oscillation, Fig. 3B. Bi-stable elements D1, D2, D3, D4 are connected in series with a resistor RO and generator G. The elements D1-D4 may be PNPN devices. Their characteristics, Fig. 4, are all the same but differ by a scale factor of 2 between each and the next. The characteristics are modified as indicated by the dotted line by circuits VS1- VS4. These each comprise a diode (D10, Fig. 5, not shown) biased by a source (E1) so as to conduct from 0-i2, Fig. 4, and from i2 to i3 to cut off so that a resistor (Rl) is inserted. At i3 a Zener diode (ZD) starts conducting in series with a diode (D11) biassed by another source (E2) to conduct until point i4, when it cuts off.. The characteristic is therefore steep when (D10) stops conducting, shallow when the Zener diode and diode (D11) conduct and steep again when this diode cuts off.

Title: Production of dehydroacetic acid
Inventor: FEWLASS MAURICE WILLIAM
IPC: C07D309/38
Filed: 1959-04-10
Abstract: Dehydroacetic acid is made by passing the vapour of an alkyl acetoacetate into the base of a packed reactor heated to a temperature from 350 DEG C. to 550 DEG C. and recovering dehydroacetic acid from the product passing from the head of the reactor.  The acetoacetate of an alkanol containing from 1 to 4 carbon atoms per molecule is preferred.  The reactor is conveniently a vertical tube packed with an inert material which remains substantially stable during the process, preferably porcelain, aluminium, stainless steel or copper.  The dehydroacetic acid may be recovered by cooling the product from the head of the reactor and separating from the mother liquor the crystals of dehydroacetic acid formed.  The alkyl acetoacetate remaining in the mother liquor may be recovered by distillation and returned to the reactor.
