Title: Process of producing soaps, cosmetics and medical preparations containing succinic acid
IPC: A61Q19/10
Filed: 1926-08-07
Abstract: 279,575. Kornatzki, H. H. von. Aug. 7, 1926. Resin oils, extracting and purifying; soaps, compositions for making.-Oil of amber obtained by the dry distillation of amber is rectified by washing with 4-6 volumes of water. The extracted succinic acid is recrystallized, mixed with the rectified oil in the same proportion as in the crude oil, and the mixture used in the manufacture of medical preparations, massaging creams, tooth pastes, and cosmetics. For example, a soap for treating rheumatism is produced by adding 1 lb. of 95 per cent alcohol to 6 lb. of boiling fat and alkaline lye, and after saponification is complete stirring in 10 per cent of the rectified oil of amber and an aqueous solution of 1-2 per cent of the succinic acid, Massaging creams are obtained by adding the same proportions of the oil and acid to emulsified petrolatum and wool-fat. Bath salts result by crystallizing out a mixture of the succinic acid and the usual salts, drying, and mixing with the rectified oil. A tooth paste is made by mixing the oil and a powdered medicated soap, and stirring in the succinic acid, glycerine, chalk, magnesium carbonate, or other suitable abrasive.

Title: Improvements in direct recovery of ammonia from the products of the destructive distillation of coal or the like
IPC: C01C1/12
Filed: 1920-07-08
Abstract: 147,736. Still, C., [Firm of]. Dec. 3, 1915, [Convention date]. Addition to 28072/12. Ammonium sulphate.-In the treatment of distillation gas on its way to the saturator, in which the gas is first directly cooled by a counter-current of water, and then directly heated by a counter-current of the same water which circulates between the cooling and heating apparatus, the quantity of water in different temperature zones of the cooler and heater is so adjusted that the greatest quantity of water is employed in the highest temperature zones and the smallest quantity is employed in the lowest-temperature zones. An additional intermediate cooling of the gas is employed between the cooler and heater as described in the parent Specification. In the apparatus described, the different temperature zones are arranged in one cooler and one heater, but separate coolers and heaters may be employed for each temperature zone, and in that case separate bodies of circulating water may be arranged between corresponding temperature zones, or the circulation may be similar to that described below. Gas at about 80‹ C. enters the cooler 2 at I, and passes through the cooling zones III, II, and I. Cooling water is drawn by a pump 21 from a tank 20 and supplied by a pipe 24 to the top of the cooler 2 serving for the lowest temperature zone I. Additional water is supplied by a pump 22 and pipe 25 to the cooler 2 at the top of the second zone II, and further water is sumpplied by a pump 23 and pipe 26 to the top of the third zone III. Washing water and condensate collect in a tank 3 at the bottom of the cooler 2, and from this the tar is drawn off at 6 and water by a pipe 7 to the top of the heater 11, into which the cooled gas enters by way of pipe 12, intermediate cooler 8, pipe 13, pump 10, and pipe 14. The gas in the heater 11 will be hottest at the top zone III, which therefore receives the most water. Water is withdrawn at the bottom of the zone III by a pipe 28 and pump 23, and further water at the bottom of the zone II by a pipe 27 and pump 22 to serve the zones III, II of the cooler 2 as above described, so that the lowest zone I<1> is served by the least water. The condensate from the intermediate cooler 8 and the washing water from the zone I<1> of the heater 11 pass to the tank 20. As the circulating water increases in volume, a part is withdrawn by a pipe 18 to a still 31, the vapours from which pass into a pipe 16 which leads the heated gas to the saturator 17. The Specification as open to inspection under Sect. 91 (3) (a) states that a cooling-coil may be placed in the tank 20 to assist or replace the cooler 8. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in apparatus for comparing frequencies of electric oscillations
IPC: H03D13/00
Filed: 1945-08-01
Abstract: 598,203. Automatic control systems for oscillation generators. BRITISH BROADCASTING CORPORATION, GOURIET, G. G., and HAMMANS, R. H. Aug. 1, 1945, No. 19831. [Class 38 (iv)] [Also in Group XXXVI] For frequency and/or phase comparison of widely different frequencies, the lower frequency is changed into pulses of duration comparable with a half-cycle of the higher frequency and are applied with the higher frequency oscillations to charge a condenser in accordance with the degree of their coincidence so that the condenser charge varies cyclically at the rate at which coincidences occur. An oscillation, e.g. of 1000 kc./sec., is applied at GH to an amplifier V2 whose output includes a condenser 24, so that the anode of valve V1 is made alternately positive and negative. An oscillation, e.g. of frequency 1000 c./sec., is applied at AB to develop pulses on the grid of valve V1. The valve V1 conducts when its anode and grid are both positive, so that condenser 24 acquires a charge dependent on the degree of coincidence of the pulses at CD and the oscillations at GH. Movement of the meter 29 indicates a wander of phase or frequency. The current through the meter may be used to correct the frequency of the oscillator supplying GH by varying the bias of a reactance valve shunting the frequencydetermining circuit. Specification 596,741, [Group XXXVI], is referred to.

Abstract: 1,157,082. inductive proximity detectors. VENNER Ltd. July 12, 1966 [May 11, 1965], No.19869/65. Heading G1N. [Also in Division G4] The presence of a vehicle in a parking location is detected by the resulting change in inductance of a coil 8, situated just under the floor of the parking location, and connected into a normally balanced A.C. bridge, whose output is supplied to a tuned amplifier 19 and rectifying level detector 17. The tuned R.F. amplifier 19 may be a simple R.C. coupled amplifier incorporating a separate band-pass filter or may include a tuned negative feed back loop utilising an R.C. tuning circuit. The output from the level detector is applied to a Schmidt trigger circuit which drives the final output circuit 18, e.g. a relay. Temperature compensating elements may be incorporated in the inductive arms of the bridge, e.g. a non-inductively wound loop wound concentrically with the coil 8 in series with the coil 9 and a similarly wound coil in series with the coil 8. Further temperature compensation of the resistive arms is unnecessary if the resistors are matched.

Filed: 1933-07-13
Abstract: 427,385. Controlling change speed gearing. WILSON, A. G., 23, Queen Anne's Gate, London. July 13, 1933, No. 19881. [Class 80 (ii)] [See also Groups XXXIV and XXVIII] Brakes for preselective epicyclic speed gears are released by a manually-controlled servo apparatus, arranged in a fluid circuit and permitting the operator to feel the power applied by the servo apparatus. The gear box described is that shown in Specifications 328,660, [Class 80 (ii)], and 402,778. Circulation takes place through ports 44, Fig. 2, ports 24, in the piston 21 and ports 45 and is interrupted by movement of a secondary piston 29 by a lever 36 connected to the brake pedal, which closes the ports 24, whereupon the piston 21 is moved to release the brakes by a link 43 and a lever 27. Pressure is exerted on the piston 29 which produces a reaction on the brake pedal. Should the fluid pressure fail, the piston 21 may be directly operated by the piston 29. In a modified form of brake cylinder the main piston 87, Fig. 3, carries the cylinder 88 for the secondary piston 92 which is integral with a poppet valve 90 adapted to interrupt the flow through the part 89 in the main piston 87. The piston 87 is connected to the brakes by a rod 43 and the valve 90 to the pedal by a rod 91. In a further modification the fluid enters ports 102, Fig. 8, in the hollow stem 101 of the main piston 100 and passes out past a valve 103 guided in the stem 101. The valve 103 is adapted to be closed by a lever 109. The pump producing the circulation of fluid comprises a plunger 64 driven by an eccentric 62, Fig. 6 reciprocating in an oscillatory block 67 and delivering fluid through a part 69. A smaller diameter part 63a of the plunger functions as a lubricating pump. In the modification shown in Fig. 6, a larger diameter part 76 is also provided adapted to give a higher power stage. Both stages 64, 76 maintain the normal circulation of the oil. When the servo apparatus is operated both stops 64, 76 develop pressure which at a certain value forces a cut-off valve 79 against a spring 85 to close the suction part 84, 77 of the plunger 76 the pressure being maintained by the stage 64 unless the pressure falls whereupon the valve 79 moves to bring the stage 76 into operation again. Vacuum may be used instead of pressure.
