Filed: 1945-06-06
Abstract: 598,197. Mixing-machines. RED CIRCLE, Ltd., and PEACHEY, S. June 6, 1945, No. 14305. [Class 86] In a concrete mixer in which the skip is raised by hydraulic power, the skip-raising mechanism is offset laterally from the mixing drum and is separated therefrom by a partition. The skip is raised and lowered by means of a hydraulic ram 26, which operates in a cylinder 17 and is pivotally connected to crank arm 24 on a shaft 23 which supports the skip (not shown). A wall 11 separates the mixing drum and skip from the drum-driving and skipraising mechanism. A pump is driven by the internal-combustion engine which rotates the mixer and supplies oil from a tank 14 through a three-way cock actuated by an arm 32. In the position shown, the cock connects with a high-pressure relief valve and oil at full pressure is supplied to the cylinder 17 to raise the skip. When the skip is fully raised, an adjustable bolt 35 carried by a lever 34 on the shaft 23 moves the lever 32 to a second position. The three-way cock then connects with a lowpressure relief valve and sufficient pressure is maintained in the cylinder 17 to hold the skip in its raised position. The arm 32 may be moved to a third position in which oil is freely discharged from the cock into the tank 14 and the skip descends by its own weight.

Filed: 1973-03-26
Abstract: 1405067 Concrete-reinforcing bars KORF INDUSTRIE UND HANDEL GmbH & CO KG 26 March 1973 [27 March 1972] 14325/73 Heading E1K [Also in Division B3] A concrete reinforcing bar is produced from i steel bar in two cold rolling passes, the first providing the bar with a curved triangular cross section, Figure 1, and the second with inclined ribs 11-13, Figure 2. The ribs blend at their ends into the bar surface and have an outer envelope of circular form, when projected axially of the bar. The second pass is offset 60 relative to the first, so that the corners of the triangular cross section provide the ribs. The ratio of the radii r v2 , Fig. 1, of the curved sides of the triangle and r v1  of the inscribed circle is between 1.6 and 2.4, and the radius r v1  is not greater than the dimension K R , Figure 2.  The method can produce bars with final diameters of from 4 to 12mm., but when the initial bar stock is not suited to the first pass, an equalizing drawing or rolling pass is made before the first pass. In some cases, two equalizing rolling passes may need to be made. The ribs may be inclined to the bar axis by from 45 to 60, have a crest width of 0.15 or 0.20 mm., and a height of 5.6 to 7.5% of the nominal diameter.

Title: Improvements in and relating to time switches
IPC: H01H43/12
Filed: 1938-05-14
Abstract: 514,716. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 14, 1938, No. 14448. Convention date, May 15, 1937. [Class 38 (v)] A switch for timing the energization of an X- ray tube 11 comprises a synchronous motor 18 which drives through worm gearing a wheel 20 loose on a shaft 21 to which it can be clutched by means of a pin 22 engaging holes 23 in wheel 20. The pin 22 is carried on a plate 24 slidably splined on shaft 21 and movable by means of a fork 26 against the action of a spring 25 by a solenoid 27. The shaft 21 carries adjustable cams 28, 29 which engage rollers 31 on contact arms 15, 17 biassed towards engagement with a fixed contact 16. The cams 28, 29 are adjusted so that contact arms 15, 17 are operated in succession and that they both engage the contact 16 for one fifteenth of a second which is the unit of time for this apparatus and is the time for one of the holes 23 to rotate into the position of the next hole. Also driven by motor 18 through a clutch 46 controlled by a solenoid 49 and reduction gearing 42, 45, is an arm 50 which is normally held by a spring 55 against a stop pin 51 but which, when clutch 46 is engaged, moves clockwise to cause a pin 54 to close contacts 36 and later contacts 37 which are adjustably mounted on an arm 52. Arm 52 may be set by a pointer 53 co-operating with a scale 51a marked in fifteenths of a second to show the time during which the circuit is closed. Starting from the position shown, with the motor 18 running and wheel 20 idling, and pointer 53 set to a desired time interval, switch 40 is depressed on to contact 38 to energize solenoid 49 to cause arm 50 to close contacts 36. This energizes solenoid 27 through contacts 34 and shaft 21 starts to rotate until circuit is closed at 15, 16, 17 and the tube 11 is energized. Cam 33 on shaft 21 then opens the circuit of solenoid 27 at 34 and closes contacts 35 and shaft 21 remains stationary until pin 54 closes contacts 37. This again energizes solenoid 27 through contacts 35 and shaft 21 rotates to break circuit at 15, 16, 17 and completes one revolution until circuit of solenoid 27 is opened at 35 by cam 33. When switch 40 is released, clutch 46 is de-energized and arm 50 returns under the action of spring 55. The time during which the circuit is closed is thus the time due to the different settings of cams 28, 29 plus the time during which the shaft 21 is stationary, that is the time taken for arm 50 to travel from the opening of contacts 36 to the closure of contacts 37 and is shown on dial 15a. The timing is exact since it depends on the number of holes 23 which pass pin 22 between the two energizations of solenoid 27.

Abstract: 634,856. Generating combustion products under pressure. AKT.-GES. FUR TECHNISCHE STUDIEN. June 4, 1947, No. 14774. Convention date, June 8, 1946. [Class 51 (i)] [Also in Groups XXVI and XXVII] In a charging set, for supplying combustion air under pressure to the combustion chamber or chambers of a hot air or gas power plant, in which the combustion air is delivered by a compressor which draws its supply from the atmosphere and which is driven by a turbine which is itself driven by the waste gases from the combustion chamber or chambers to which the air is supplied and in which a heat exchanger is provided for heating the combustion air which is on its way from the compressor to the combustion chamber or chambers and for consequently cooling the waste combustion gases which are on their way from the combustion chamber or chambers to the turbine, a byepass for the waste gases is arranged across the heat exchanger and means are provided for varying the relative flow of the waste gases through the heat exchanger and byepass. The byepass enables the amount of energy given up by the waste gas turbine to be adapted to the amount of energy consumed by the compressor. As shown charging air is supplied to a combustion chamber 9 by a compressor 1 through pipes 2, 5, 8 and heatexchangers 3, 6. The compressor is driven by a turbine 14 operated by exhaust gases from the combustion chamber. Before passing to the turbine the exhaust gases heat the air supplied by the compressor in the heat-exchanger 6 and after leaving the turbine pass through the heat-exchanger 3. The air from the compressor is pre-heated in the heatexchanger 3 before it reaches the heat-exchanger 6. The heat-exchanger 6 has a byepass pipe 18 for compressed air and a bypass pipe 16 for exhaust gases these byepasses being controlled respectively by valves 19, 17. In the combustion chamber 10 piping 11 is arranged in which a working medium of a power plant is heated. When the byepass 16 is open the pressure at the inlet to the turbine is higher than when the byepass is closed. The temperature of the exhaust gases flowing to the turbine can be varied by altering the quantity of air passing through the heat exchanger by means of the valve 19.
