Patent GB-242677-A (GB)
Title: Improvements in or relating to surface condensers
IPC: F28B9/04
Filed: 1925-11-10
Abstract: 242,677. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Nov. 10, 1924, [Convention date]. Surface condensers.-In order to obtain water of condensation of approximately uniform temperature with cooling water of varying temperature, the length of the path of the cooling water is varied. In the condenser shown in the Figure, the normal path of the cooling water from the inlet d is through a valve b, the lower cooling tubes, and a valve c and through the remainder of the cooling tubes. If colder water is to be used, the lower tubes are cut out of the path by opening a valve a and closing the valve b. The cooling water then passes through a by-pass tube e arranged externally of the condenser. The lower tubes may be drained by a valve, not shown, to prevent corrosion. The output of the pump for the cooling water may be reduced either by throttling or by reducing its speed in view of the less resistance to the flow of the water in the shortened path.
Patent GB-1079594-A (GB)
Title: Improvements in or relating top fluid pressure operated calculating machines
IPC: F15C3/00
Filed: 1965-07-05
Abstract: 1,079,594. Fluid controlled calculating apparatus. NATIONAL CASH REGISTER CO. July 5, 1965 [July 22, 1964], No. 28345/65. Heading G4P. Fluid relays in a fluid-operated calculating machine comprise a stack of plates with a piston accommodated in a recess in the stack, the piston being reciprocable so that inlet ports in the plates may be brought into coincidence with outlet ports or disconnected therefrom. Addition.-Numbers entered in decimal form on the keyboard are first converted into binary coded decimal form. When, for example, the amount key 62a (Fig. 29) representing the digit "7" is depressed, relay 238 is operated to give output flow along channel 239 which results in the switching of relays 242a, 242b and 242c and hence flow along channels 234, 235, 236 but not along channel 237. These outputs are applied to a K register (Fig. 28) which comprises several stages each having four input flip-flops and four memory flip-flops. The output from the K register is used in three ways, (a) it is applied to a keyboard indicator 22, (b) it is applied to a binary conversion unit, (c) it is transferred to an adder 34a (not described) where it is added to the contents of the A register and the result stored in the A register. The rotation of the indicator segment 135 (Fig. 17) is controlled by pistons 127-130 which are operated or not according to whether or not a binary "1" or " 0 " is stored in the associated chambers 126a. The distance moved by the pistons is weighted according to their binary value. The binary conversion unit 38 (Fig. 22) comprises pistons 143 to 146 which control the positions of slides (193-196, Fig. 25, not shown) so that certain notches in the slides are in alignment to define a slot representing the decimal digit which is then printed. Multiplication.-On depression of an "enter" multiplier key the number set up on the keyboard is entered into the M register. The multiplicand is then entered into the K register. On depression of the " multiply key " the product of the K register and the M register is entered in the A register and the M register is then set equal to the A register. Error preventing.-Relays are also described (Fig. 31, not shown) in which if the fluid pressure is cut off the pistons are locked in position until the power is restored. Since the switching of one of the relays associated with the keys (62a, Fig. 29, not shown) is only possible when all the lower amount relays have not been switched, simultaneous depression of two keys 62a results in only the lower amount key being effective.

Title: Improvements in the manufacture of gramophone disc records
IPC: G11B3/70
Filed: 1922-10-18
Abstract: 209,835. Columbia Graphophone Co., Ltd., and Jones, F. W. Oct. 18, 1922. Moulding gramophone records.-Disc records which are homogeneous, as distinguished from laminated discs made of different materials, are formed from powdered thermoplastic material. According to one process, the powder is fed on to a plate or into a mould heated to a temperature at which the powder can be made to cohere under pressure, and the material is then pressed by means of a cold roller or by other means, so forming a porous disc on which a record is subsequently impressed in the usual manner. Alternatively, the powdered material may be fed into a mould containing the record-impressing matrices, where it is subjected to the ordinary processes of heating, pressing, and cooling. A thermoplastic material consisting basically of cellulose acetate may be employed.

Abstract: 1,116,445. Golf practice device. G. BURGER. 1 July, 1966 [7 July, 1965], No. 28866/65. Heading A6D. [Also in Division G1] A golf practice device of the kind having a tee and a screen a short distance from the tee towards which golf balls are driven comprises a first switch actuated by the departure of a ball from the tee, a second switch actuated by the arrival of the ball at the screen, a capacitor, a resistor, registering means and means for initiating, on actuation of said first switch the charging or discharging of the capaacitor through the resistor and connecting, on actuation of the second switch, the registering means  across the capacitor to register the charge stored thereon. With the circuit in the figure a golf ball placed on the tee interrupts a light beam to a photocell and a potential is applied to transistor 6 to energise relay A3. Contact of relay A3 moves to allow capacitor C2 to charge through resistor RV1. When the ball is driven from the tee transistor 6 is cut off, relay A3 is deenergised and contact 1A changes to positon shown and initiates discharge of capacitor through resistor RV1. This discharge is terminated when the ball strikes the screen and a switch connects leads 7 and 8. Relay B4 is energised and voltmeter V connected to terminals 9 and 10 is connected in series with a resistor RV2 across capacitor C2. The voltmeter receives the remaining charge on C2 and the deflection indicates the distance the ball would have travelled. A second needle is carried forward by the first to indicate the reading and is returned to zero by a reset motor.

Title: Improvements in or relating to the manufacture of p-amino-salicyclic acid
Filed: 1950-11-27
Abstract: In a batch process for the manufacture of p-aminosalicylic acid, m-aminophenol is heated in water with potassium carbonate, bicarbonate or hydroxide, in an atmosphere of carbon dioxide, at not below 75 DEG  C., cooling, separating and acidifying the liquid with sulphuric acid to pH approximately 6, separating the solid potassium sulphate, warming the liquid to 35-40 DEG  C., acidifying with sulphuric acid to 5.1 or 5.0 pH, to precipitate the p-aminosalicylic acid, washing the precipitate, concentrating the filtrate and washings and returning, with added potassium bicarbonate to the residue of unreacted starting-materials for a further batch reaction. Superatmospheric pressure may be employed.  Reducing agents such as sodium hydrosulphite or hyposulphite may be added in acidifying, with or without animal charcoal or other decolorizing agent.  In an example, 30 repetitions of the process gave a 95 per cent yield of the product.
