Title: Improvements in or relating to power driven hand-guided machines
IPC: F16D43/21
Filed: 1937-08-27
Abstract: 480,937. Drilling &c. machines. BOSCH AKT.-GES., R. Aug. 27, 1937, No. 23471. Convention date, Sept. 30, 1936. Addition to 480,899. [Class 83 (iii)] [Also in Groups XXIV and XXXV] In a portable power-driven tool for drilling &c. the clutch described in the parent Specification has the springs mounted near the periphery of the clutch so as to be freely accessible to air cooling over their whole length. The motor casing is in two parts 1, 2 and the short-circuit armature 11 of the motor is secured to a hollow shaft 12 mounted at one end in a bearing in the end plate 7. A spindle 13 passing through the shaft 12 is mounted in bearings in the end plates 2, 7 and is connected by gearing to a drill-spindle arranged at right-angles thereto. A driving member 14 is keyed to the shaft 12 and carries lugs 14b which engage notches in the periphery of clutch plates 16, the alternate clutch plates 17 being notched to a central nut 18 mounted on quick-pitch threads 13a on the driven shaft 13. Axial pressure is applied to the clutch plates by springs 22 surrounding pins 21 which are riveted at one end to a pressure plate 19 and are attached to a ring 23 by pins 25. The springs 22 abut on the ring 23 and press a pressure plate 20 towards the plate 19. Fan blades 20a are provided on the plate 20 to draw air through holes 2b in the casing 2 and direct it over the springs and then through holes 2a, and fan blades 14a on the member 14 draw air through the motor and pass it out through holes 1a in the casing 1. The pressure plates 19, 20 engage opposite sides of the nut 18 through thrust bearings 26 so that if the drill meets excessive resistance the nut will screw along the shaft 13 in one direction or the other, according to its direction of rotation, and carry with it one of the plates so as to free the clutch plates and stop the drive. Bolts 15 passing through the lugs 14b prevent axial motion of one of the plates 19, 20 when the clutch is released. An angle casing on the end of the tool, which supports the drill spindle, also supports a rotatable feed screw in line with the drill.

Title: A semiconductor arrangement
IPC: H01L23/051
Filed: 1964-06-05
Abstract: 1,065,897. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. June 5, 1964 [June 15, 1963], No. 23520/64. Heading H1K. A semi-conductor device is sandwiched between two thermally conductive contact plates and the composite assembly is mounted within a housing in which two end cover members are each attached to a ring of insulating material, each ring being secured to a metal connecting part and the two connecting parts being joined to complete the housing. Each end cover member has around its central portion a portion projecting into the housing; the semiconductor device and its contact plates rest loosely within these projections which prevent the composite assembly from shifting laterally within the housing. The manufacture of a unit is shown in Fig. 3. The insulating rings 11, 12 are preferably made of sintered alumina. The parts may be pushed together by punchlike tools 17, 18 and the metal connecting parts 15, 16 joined by hard soldering or welding (e.g. the argon arc process). During the jointing the punch-like tools may be used as heat-sinks and are therefore made, for example, of copper. The connecting members (typically made of an iron-cobalt-nickel alloy) may be additionally joined by flanging their outer ends. The device within the housing may be a diode rectifier in which, case the contact plates rest against the alloyed electrodes, or it may be a transistor or a four-layer controlled-rectifier in which case a lead from the third electrode extends out of the housing laterally between the metal connecting parts 15, 16. Electrode arrangements of three electrode devices are described and are such that the two contact plates may bear against the main electrodes. An enclosed device may be used and stacked as disclosed in Specification 1,009,359.

Patent GB-900190-A (GB)
Title: Method of and apparatus for withdrawing a cop thread end
IPC: B65H67/08
Filed: 1958-07-23
Abstract: 900,190. Winding yarns. RE NERS, W. July 23, 1958 [Aug. 3, 1957], No. 23679/58. Class 120 (2). In withdrawing the outer end of a cop terminating in a reserve coil wound on an end of the cop tube, the coil is drawn off by a free stream of compressed air directed towards the coil. The drawn off coil may be entrained in a stream of suction air by which it is located in a substantially fixed position and the thread end may be further removed by moving the cop axially in the opposite direction or by rotating the cop in an unwinding direction. The speed, pressure and/or direction of the arc stream may be variable and these variations may be effected abruptly, linearly or sinusoidically. Fig. 1 shows the invention applied to an automatic thread winding machine in which a magazine 1 contains cops 2 adapted to be released one at a time for transfer to the unwinding position. For this purpose the magazine is fitted with an escapement fork 3. Each cop is formed with a reserve coil R which must be drawn off before the cop moves to the unwinding position. For this purpose a nozzle 5 is provided which directs a stream of air on to the coil R to unwind it and direct it into duct 4 which is subjected to a suction so that the thread end is held therein. Thereafter the cop is released and slides down the shoot 6 to position 2b and thence to the unwinding position 2c. The thread portion F<SP>1</SP> extends down the shoot past a shears device 8 and across the open end of a nozzle 9. The shears sever the thread, the severed end being removed by duct 4 and the remaining portion being directed upwards to position F<SP>2</SP> by an air stream from nozzle 9. The thread is then gripped by pivoted suction arm 10 which transfers it to knot tying device 12 where it is united with the thread end from the package being wound and the thread takes up the position F<SP>3</SP>. A pivoted feeler 21 is engaged by the thread and controls the stopping of the machine and initiates a repair or cop replacement operation. The feeler 21 is also connected by a lever and link system 22 to a rotary valve 26 in the supply pipe to nozzle 5. Instead of shears 8 a jet of compressed air may be used to sever the thread. In a second embodiment the cops in the magazine are arranged with their noses adjacent to the knot-tying apparatus so that the thread end is blown directly to the tying position. In another embodiment, a jet of air is used to rotate the cop to assist in the unwinding of the thread end after the coil R has been removed. Specification 900,191 is referred to.

Title: Improvements in or relating to the fuels for diesel and like engines
IPC: C10L1/02
Filed: 1945-09-14
Abstract: Fuels for starting and running high-speed compression ignition engines at low temperatures comprise a hydrocarbon Diesel fuel base, preferably having a cetane number of at least 40, blended with a normal dialkyl ether boiling below 100 DEG  C., the ether constituting from 5 to 80 per cent by volume of the blend.  The ether may be diethyl, ethyl propyl or methyl ethyl ether, and may constitute from 20 to 60 per cent and preferably from 40 to 50 per cent by volume of the blend.  The incorporation of ethers of the above type in the fuel is said to lower materially the temperature at which Diesel engines can be started and to lower the cloud and pour points of the fuel, the operating efficiency of the engines at low temperatures being thereby improved.  In an example, 50 per cent by volume of diethyl ether is blended with 50 per cent of conventional Diesel hydrocarbon fuel of 35 S.S.U. viscosity at 100 DEG  F. Specification 599,132 is referred to.

Title: Manufacture of cyclopentadienyl manganese carbonyl compounds
IPC: C07F17/00
Filed: 1958-07-24
Abstract: Cyclopentadienyl manganese tricarbonyl compounds (e.g. methyl cyclopentadienyl manganese tricarbonyl) is added to gasoline to increase the octane rating.ALSO:Cyclopentadienyl manganese tricarbonyl compounds are prepared by reacting a bis(cyclopentadienyl) manganese compound with carbon monoxide, the bis(cyclopentadienyl)manganese compound being prepared by reacting a cyclopentadienyl alkali metal compound with manganous chloride at a temperature above 100 DEG C. in a glycol dialkyl ether solvent which is present in a concentration of not greater than 1 mole per mole of manganous chloride.  The carbonylation reaction may be carried out at a temperature from 50 DEG C. to 300 DEG C. using carbon monoxide or a compound which liberates carbon monoxide such as a carbonyl of a metal of Group 1 (b), V (b), VI (b) and VIII of the Periodic Table (Deming). Ethers specified include ethylene glycol-dimethyl, -methylethyl, -diethyl, -methylbutyl and -butyllauryl ethers, and diethylene glycol-dimethyl, ethylmethyl, -diethyl, -ethylbutyl, -dibutyl, and -butyllauryl ethers, and dimethyl and diethyl triethylene glycol ethers.  The same solvent as is used in later stages may be used for the preparation of the alkali metal cyclopentadienyl compound to be used as starting material for this bis(cyclopentadienyl)manganese compound.  The product of the carbonylation reaction may be isolated by distilling the reaction product mixture to remove the major quantity (above about 90%) of the ether and cyclopentadienyl hydrocarbon are removed leaving a concentrated stream containing the cyclopentadienyl manganese tricarbonyl and only minor (less than 5%) of the ether and/or hydrocarbon, and then subjecting this concentrated stream to a second distillation to form a second vapour stream containing the residual quantities of ether and/or hydrocarbon and a portion of the cyclopentadienyl manganese tricarbonyl.  This second vapour stream is recycled back to the first distillation for treatment with fresh impure mixture.  The purified stream may then be fractionated.
