Title: Continuously-operating retorts for the production of gas
IPC: C10B3/00
Filed: 1937-02-18
Abstract: 467,329. Steaming gas retorts. SCHROTH, W. Feb. 18, 1937, No. 4901. [Class 55 (i)] In a continuously operating retort for the production of coal gas, the water gas generated by steaming the charge in the lower part of the retort is withdrawn by a byepass duct 8 directly to an externally heated free space above the charge, in which space the water gas mixes with the distillates and is withdrawn through an outlet 5. By this means, tar forming hydrocarbons are cracked into gases or vapours in the hot charge in which the scavenging effect of the water gas and steam mixture is avoided. Steam is admitted through pipe 7, superheated in zone 3 and partly converted into water gas in zone 2.

Title: Improvements in or relating to screw-threaded members
IPC: F16B39/30
Filed: 1943-04-02
Abstract: 566,627. Locking studs &c. BRISTOL AEROPLANE CO., Ltd., and GOODBY, W. T. April 2, 1943, No. 5289. [Class 89 (i)] [Also in Group XXVIII] Studs and like screw-threaded members are so formed that on being screwed into place they displace material from the tapped member to form a collar whose diameter is less than the crest diameter of the threads of the stud and which consequently forms a lock. The stud &c., Fig. 3, has a thread 21 rolled from a portion of diameter x; leaving a plain portion 22 between the threads and a locating collar 16 of diameter w. The member 10 that is tapped to receive the stud is drilled to a diameter y equal to the root diameter of the thread and has a counterbore 24 of diameter w. On screwing in the stud when the plain part 22 encounters the threads, it displaces the crests to fill the troughs, thus forming a collar 26, Fig. 6, that is consolidated when the locating collar 16 bottoms in the counterbore 24. The locating collar 16 facilitates seating the studs with a uniform amount projecting. The material of the member 10 may be softer than that of the stud, for example, an aluminium alloy for use with steel studs. The studs may be applied to junkheads for internal-combustion engine sleeve valves, supercharger casings and gear boxes, and threaded parts of pipe joints and sparking- plug adaptors may be similarly constructed.

Title: Improvements in and relating to electrical interpolating apparatus
Inventor: AINSWORTH JOHN DESMOND
IPC: G05B19/4103
Filed: 1957-02-15
Abstract: 896,001. Electric copying machines. ENGLISH ELECTRIC CO. Ltd. May 14. 1958 [Feb. 15, 1957], No. 5309/57. Class 38 (6). [Also in Group XIX] Interpolating apparatus for controlling the movement of a milling cutter between successively received digital input signals and in response to clock pulses, or pulses derived from movement of a work-table comprises registers A-C (Fig. 2) for the input values and derives " forward" and " reverse " pulses for outputs F, R correcting the cutter position at any of 128 points of the interval. Fig. 2 shows diagrammatically apparatus for inpolating a series of values of X between the values at successive points W, X, Y, Z (Fig. 1) with a constant difference t 0  in argument t by deriving for each interval such as XY two step functions approximating respectively to f 1 ,the linear function producing the increment d 2 , and f 2 , the parabolic function equal to 0 at X and Y and to h = d 1  - d 3  / 16 at the mid-   point, and adding these step functions. The apparatus enters and transfers the differences d 1 , d 2 , d 3  . . . successively through gates 10 and 11 into registers A, B and C, the gates being opened by timing pulses obtained by successive division by two by dividers 13 of pulses from generator 12 producing 256 pulses between each transfer. Each register A-C holds a 9-bit word comprising an eight-digit binary number representing the value of the difference and a sign digit. At the instant shown in Fig. 2, register B holds d 2 , and this is linked to gate unit 15 (Fig. 3, not shown) which acts so that each digit of d 2  opens gate for the output of the corresponding divider 13 so that the output from unit 15 consists of d 2  pulses on line F or R depending on the sign of d 2 . This passes to a mixer 28 where the pulses are added to those obtained by subtracting d 1  and d 3  in 14 and using the five most significant digits of the result to gate at 18a and 18b pulses from non- linear pulse generators 19a, 19b. Gate units 18a and 18b are similar to gate unit 15; units 19a (Fig. 5, not shown) and 19b each have five output lines on which 1, 2, 4, 8 and 16 pulses respectively appear during one of the half to intervals -, the distribution of these pulses 2  being shown for unit 19a in Fig. 7 at A, B, C, D and E respectively. Fig. 8 (b) shows the step function output of gate 18a for the half interd 1  d 3  val obtained when - = 15; the sign digit 16 from 14 ensures that it is directed as a positive input to 28, and 18b produces a mirror image step-function fed to 28 as a negative input.

Title: An improved foot control system for motor cars and the like
Filed: 1932-02-23
Abstract: 396,831. Controlling motor vehicles. MARTIN, J., 51, Bellwood Street, Langside, Glasgow. Feb. 23, 1932, No. 5343. [Class 79 (v).] Foot control mechanism for motor vehicles comprises two pedals, one controlling the brakes and the other being arranged when it is depressed to open the throttle and engage the clutch, the simultaneous depression of both pedals causing the clutch to be disengaged. In the construction shown, the clutch is disengaged by means of a vacuum cylinder I adapted to be connected to the induction pipe by a valve G operated by a link N connected to a floating lever R positioned by a link L. The accelerator pedal F is connected to the lever R by a link M and to the throttle H by a link O, so that when the pedal F is depressed the throttle is opened and the lever R turns about the end remote from the link M so as to operate the valve G and allow the clutch C to be engaged by its spring P<1>. When the pedal is released the throttle closes, and the valve G is operated so as to connect the cylinder I to the induction pipe and thereby disengage the clutch. The brake pedal E is connected by a link K to the floating lever R, and when this pedal is depressed to apply the brakes it rocks the lever R to operate the valve G and thereby disengage the clutch if it is engaged. If the pedal F is depressed at the same time the clutch is nevertheless disengaged by the pedal E since the latter has a much greater effect on the valve G than the pedal F has, due to the disposition of the point of connection of the link N to the lever R. The pedal F may be arranged to release the clutch when depressed and to open the throttle when raised.

Title: Process for the manufacture of dihalogenoethyl esters
IPC: C07C69/63
Filed: 1929-02-19
Abstract: 325,115. Ellis, G. B., (Soc. des Usines Chimiques Rhone-Poulenc). Feb. 19, 1929. Dihalogen ethyl estcrs are prepared by treating vinyl esters with a halogen at a low temperature. The halogen may be advantageously used in slight excess, which may be removed by bubbling an inert gas through the mixture, or by adding the necessary amount of vinyl ester and allowing it to stand. The process may be carried out in the presence of diluents, e.g. carbon tetrachloride or benzene. In an example, 86 parts of dry vinyl acetate are stirred in a lead apparatus whilst a stream of chlorine is slowly bubbled through, the temperature being maintained at 0‹ C. When 72 parts of chlorine have been introduced, the excess is eliminated by passing a stream of air through the liquid, or by adding 1.2 parts of vinyl acetate and allowing to stand for 1 hour at room temperature, whereby dichlorethyl acetate is obtained. In another example bromine is run slowly into dry vinyl acetate maintained at 0‹ C., dibromethyl acetate being obtained. Other examples describe the preparation of dichlorethyl monochloracetate and dibromethyl butyrate.
