Abstract: 782,356. Heat treating steel. GENDERS, R., and KEMMISH, W. B. April 21, 1955 [Jan.27, 1954], No. 2500/54. Class 72 [Alsoin Group XII] A method of heat treating carbon or low alloy steel bars comprises heating the bars to above the temperature of austenite formation, spraying with coolant to cool the surface to a temperature above the start of martensite formation, heating the surface cooled bars to a temperature between 300‹C. and 700‹C. cooling and subjecting the bars to a mechanical treatment, and finally subjecting the bars to a low temperature heat treatment. As shown, the bars 11 are heated to above the austenite temperature in a furnace 10, moved through a series of rings 13 which supply a spray of water, by a push rod 16 and then into a furnace 19 held at a temperature of 300-700‹C. The bars are then cooled and subjected to a mechanical treatment e.g. reeling, straightening, or cold drawing, and then given a final treatment at 200-600‹C. The process is stated to give low alloy or carbon steel a tensile strength of 50-65 tons per square inch and an Izod value of 35 ft. lbs.

Title: Improvements in or relating to Communications Systems
IPC: H04Q11/04
Filed: 1967-01-18
Abstract: 1,171,333. Automatic exchange systems. SIEMENS A.G. 18 Jan., 1967 [19 Jan., 1966], No. 2555/67. Heading H4K. In a system including a plurality of TDM exchanges which are linked by TDM highways, time slot interchange between the time slots allotted to two subscribers in different exchanges is facilitated by means of stores attached to the incoming ends of the highways. There is one store per channel of the highway. As shown, local subscribers of exchanges A or B are connected together by synchronous operation of two switches s11 . . . s1n or s11<SP>1</SP>... s1n<SP>1</SP> utilizing pulse amplitude modulation, resonance transfer techniques. In order to connect an A subscriber to a B subscriber, the relevant line gates, e.g. s11 and highway gate s2 are pulsed during one time slot so as to transfer energy to capacitor C o . During the next time slot gate s4 and a gate such as s61<SP>1</SP> (in exchange B) are pulsed so as to transfer the charge on C o  into capacitative store Sp1<SP>1</SP>, any residual charge on C 0  being removed by pulsing s3 during the third time slot. In the time slot just previous to that allocated to the subscriber at B, gate s51<SP>1</SP> is pulsed so as to transfer the charge to Co<SP>1</SP> whereby in the allotted time slot, synchronous pulsing of gates s2<SP>1</SP> and, e.g. s11<SP>1</SP> completes the energy transfer between the two subscribers. A similar process occurs for transmission in the opposite direction, capacitor C o <SP>1</SP> being " charged " with an outgoing signal during the last mentioned allotted time slot. The method of selecting stores 5p or of synchronizing the closure of 84 and s61-s6n<SP>1</SP> is not specified. Although P.A.M. is used within the exchanges, P.P.M or P.C.M. is used on the interexchange highways, the P.A.M. signals being compressed (expanded) prior to (after) the change in the form of modulation. Reference has been directed by the Comptroller to Specificadion 904,231.

Abstract: 541,105. Transmitting mechanical power ; centrifugal governors. LIEBRECHT, H. F. Feb. 10, 1940, No. 2585. [Class 38 (iv)] [Also in Group XXVI] An electromechanical infinitely variable speed gear has two or more epicyclic gears in series relation and electrical means byepassing energy from one part of the epicyclic gear to another. Fig. 1 shows a transmission system in which the load shaft k is driven from the element h of an epicyclic gear of which the elements i, g are respectively driven by the elements c, e of another epicyclic gear of which the element d is driven by a prime mover. In order to balance the tangential forces on the elements g, i at various velocity ratios of the transmission a dynamo driven by the elements c is connected to a motor driving the element g, for example by being coupled to the reversing pinion r shown. The electrical machines may be single or polyphase types but are preferably D.C. so that they may serve for starting the prime mover and for lighting and charging the battery on a vehicle. Preferably the dynamo is independently or shunt excited and the motor series wound, but other arrangements are suggested, including a machine with a single field and two armatures respectively inside and outside the field magnet. Clutches may be provided at x or x<SP>1</SP> to lock the first epicyclic gear. Band brakes may be arranged at v and wand a clutch may be interposed at y. When driven by an internal combustion engine having a spring loaded governor the spring tension may be varied according to the speed of the output shaft of the transmission by an auxiliary centrifugal governor. Specification 529,248, [Group XXIV], is referred to.

Title: Improvements in or relating to hydraulically operated machines for surface broaching
IPC: B23Q5/06
Filed: 1935-01-28
Abstract: 451,111. Hydraulic broaching-machines. KING, T. ST. P. C., c/o Lapointe Machine Tool Co., Ltd., Edgware, Middlesex. Jan. 28, 1935, No. 2814. [Class 83 (iii)] A hydraulically-operated broaching-machine has a control valve which is automatically reversed at the end of each working stroke by means of linkage operated by a cross-head secured to the lower end of the ram and carrying the broaching tool. The piston 2 of the ram cylinder 1 is carried by a rod 3 connected to a cross-head 4 carrying the offset broaching slide 5. Pressure fluid is supplied by a variable delivery pump 6 drawing from a tank 7 and delivering through pipe 28 to the channel 25 of the control valve 8, which includes a sliding element fitted with piston portions 10-13 and automatically operated through a lever 45 and other linkage from a rod 39 carrying collars 41, 42 coacting with the cross-head 4. The valve may also be manually operated from a handle 46 or from a pedal. Another port 29 in the valve leads through a pipe 30 to a back pressure valve 31 which may be of the kind described in Specification 447,300, [Group XXIX]. This valve communicates with the tank through a line 35. A line 20 from the valve communicates with the tank and has a branch 36 passing through a filter 52 and circulating round the pump 6 for cooling the pump. In operation, to start the cycle the valve is moved to the Fig. 2 position wherein the pump flow passes to the top of the ram cylinder and discharge from the ram cylinder passes through the valve to the back pressure valve which establishes a predetermined back pressure under the piston 2. At the end of the working stroke the head 4 engages the projection 42 and moves the valve to a position wherein the ram is reversed and exhaust from the upper end of the cylinder passes along the line 20 to the tank. As the piston reaches the upper end of its travel the valve is again reversed so that the cycle may be repeated automatically. Alternatively, the ram may be stopped by means of the handle 46. In a machine embodiment, Fig. 4, the work is mounted on the table 47 and pedal control 48 is provided. The pump output is adjustable from a control 51.

Patent GB-787896-A (GB)
Title: Recovery of chlortetracycline from solutions thereof
IPC: C07C233/00
Filed: 1955-02-01
Abstract: Chlortetracycline is isolated from an impure aqueous solution containing it by treating the solution with water soluble salts of more than one metal of Group II of the Periodic Table at a pH between 7 and 10 and preferably 8 to 9.  Specified metals are barium, strontium, calcium, magnesium, zinc, beryllium, cadmium and mercury. The water-soluble salts such as the chloride, bromide or nitrate, may be added in any proportion and the constitution of the complex produced depends upon the particular metal salts added, the proportions in which they are added and the particular polyvalent metal ions which may be present in the impure solution of chlortetracycline.  Depending upon the toxicity or otherwise of the polyvalent metal ions, the complex may be used therapeutically, as an animal growth stimulant, as a plant growth stimulant or as an industrial bactericide.  A preferred complex is one produced by adding to the chlortetracycline solution a barium and magnesium salt in the proportion of 1 part magnesium salt to 2 parts of the barium salt.  It is preferred to adjust the pH after the addition of the salts.  Chlortetracycline may be recovered from the complex by treatment with an acid which forms insoluble salts with the metals of the complex, e.g. sulphuric acid in the case of calcium chloride-barium chloride complex, separating the insoluble metal salts so produced and adjusting the acid solution to pH 6-9 and preferably 7.0 to precipitate the antibiotic. Further purification may be obtained by dissolving in acidified methanol and adding acid, e.g. hydrochloric to precipitate the acid salt of chlortetracycline. Specification 787,895 also is referred to.
