Abstract: 1,176,710. Work-table feed device in milling machines. J. PARKINSON & SON (SHIPLEY) Ltd. 31 May, 1968 [12 June, 1967], No. 26998/67. Heading B3K. A control device for positioning a workcarrier relative to a cutting tool in a machine tool, particularly in a knee-type milling machine, comprises a rotatable feed screw 6 and a non-rotatable nut 7 for adjusting the position of the work carrier, the nut being carried by a hollow piston-rod 5 of a fluid-operated piston and cylinder unit 4, 3 which is operable to move the piston and nut and thereby the screw and workpiece carrier as required between two predetermined levels. The device is particularly adapted for lowering a workpiece away from a milling cutter for the retraction stroke of the work-table and to this end the piston-rod 5 is threaded at 8 and carries an adjustable micrometer stop ring 9 having an abutment face 14 adapted to engage the end face 15 of a portion 12 of the cylinder 3. Electrical switches 16, 18 operable at the respective ends of the stroke of the piston-rod provide for operation of the device in conjunction with an automatic cycle control system for the machine tool and table.

Title: An electric measuring apparatus for measuring the time integral of momentary pulses
IPC: G01R1/30
Filed: 1957-08-28
Abstract: 858,240. Electric meters. STATNI VYZKUMNY USTAV TEPELNE TECHNIKY PRAHA. Aug. 28,1957 [Aug. 29, 1956], No. 27088/57. Class 37 Apparatus for measuring the time integral of current pulses comprises a parallel resonant electrical circuit which simulates a ballistic instrument one branch of the circuit including a capacitance and the other a coil and resistance in series, the current through the coil being stated to be proportional to the time integral of an applied voltage pulse. Detailed mathematical proofs are included in the Specification to prove this and to show that the circuit of Fig 1 satisfies the equation A o i 1  1 + A 1 i 1  1   + A 2 i 1 =u (t) which is analogous to the ballistic equation J#<SP>11</SP> + wcp<SP>1</SP> + D# = F(t) where AoA  1  and A 2  are constants given by the circuit constants R  1 , L, R and C and the differential coefficients for both equations are in respect of time, the constants of the ballistic equation having their usual meaning. A practical circuit is shown in Fig. 3, the anode voltage corresponding to u(t) of Fig. 1, u g (t) denoting the grid voltage of tube 5, the current i  1 (t), the maximum value of which corresponds to the time integral of an applied pulse, being measured by an oscillograph 6 the resistance of which must be added to resistance 4. Current i kohp compensates for the anode idle current.

Title: Improvements in or relating to the manufacture of composite conductors
IPC: H01L21/60
Filed: 1965-06-25
Abstract: 1110583 Conductors; super-conducting AVCO CORPORATION 25 June 1965 [17 July 1964] 27135/65 Headings H1A and A4D A composite conductor is made by coating an elongated super-conductor member with a first metal, then embedding it in another metal incapable of forming a compound of high thermal or electrical resistance with the first metal, and heating below the melting points of the various metals to interdiffuse the first and second metals. The first and second metals are chosen to be normally conducting at the transition temperature of the super-conductor. Typically, niobiumzirconium alloy wires electro-plated with copper are cleaned and disposed in grooves in the face of a copper or aluminium strip which is then rolled or pressed so as to grip the wires. The assembly is then annealed by heating in vacuum or inert gas for an hour at 560C. Alternatively, a composite wire is made by placing the coated wires with copper wires in a copper tube and pressing them together in a die before annealing. Other suitable materials for the wire are molybdenum-rhenium, bismuth-lead, niobium-titanium, niobium-tin and vanadium-gallium alloys and for the coating, which may alternatively be applied by vapour deposition, aluminium, cadmium, gold, silver, platinum and rhodium.

Filed: 1927-10-15
Abstract: 288,907. Carlaw & Sons, Ltd., D., and Carlaw, D. Oct. 15, 1927. Envelopes, making.- In envelope - making machines in which blanks fed from a pile are gummed and passed on to a folding plunger, the lowermost blanks are delivered singly and successively by suction or other means into engagement with means for withdrawing them from the pile and feeding them directly past gummers, acting immediately after the withdrawing means, to the folding plunger. The gummers may be associated with a conveyer which feeds the blanks to the folding plunger. A pile of envelope blanks 1 overhangs the edge of a sloping table 2, their outer ends being supported by a pivoted catch 7 above an oscillating suction nozzle 12 adapted to bend down the end of the lowermost blank into an opening 15 in a feed cylinder 16. Arcuate portions 17 on the cylinder engage, the bent end of the blank between the cylinder 16 and a feed roll 19 adapted to pass it along guides 20 and beneath a stripper plate 21 on to a carrier plate 22. Projections 26 on a conveyer 23 pass the blank along the carrier plate beneath gumming rollers 30, 31 which apply gum to the front and rear flaps of the blank. Each roller is supplied from a tank 32 by a roller 33 therein, the roller contacting periodically with a roller 34 mounted on rooking arms 36 and supplying the roller 30 or 31 through a roller 35. Carrier plates 38, 39 are mounted in line with the plate 22, gaps 40, 41 being left beneath the gumming rollers 30, 31 to prevent the gum from coming into contact with the plates. The machine is made adjustable for different sizes of blanks by mounting the parts on parallel bars 56 connected by transverse rods 58, 59 each formed with left and right hand screw threads. Clamping devices secure the rods in their adjusted positions. Specification 273,050 is referred to.

Abstract: 274,314. Hochstetter, F., and Schmeidel, G. Oct. 4, 1926. Preserving animal and vegetable substances.- Animals, plants, and parts thereof are preserved in their natural state by fixing the tissues, dehydrating with alcohol &c., soaking in benzene or other hydrocarbon solvent, the solvent being finally replaced in the tissues by molten solid hydrocarbons such as paraffins which are then allowed to solidify. Fixing is effected by immersion in a fixing solution, fixing solution being first injected in the case of the larger specimens. The fixing solution may consist of a mixture of alcohol and chloroform, or of a mixture of glacial acetic acid, alcohol, chloroform, and, optionally, formaldehyde. Anhydrous phenol or creosote may be added to the alcohol and the hydrocarbon solvent. After treatment with the paraffin, which may be kept molten by a thermostat, the excess paraffin may be removed by placing the specimen for some time on blotting paper in the thermostat.

[Also in Division D1] In a frame for stretching a thermoplastic film of synthetic organic material and having travelling clip chains and means for supplying heat to the film, each clip chain is cooled over at least the last part of its return path in a cooling duct through which cooling air flows. Each clip chain may be additionally cooled by fluid sprays and by passage of cooling liquid through a tube or tubes. In one embodiment (Fig. 1) a thermoplastic film F is gripped at both sides by tensioning clips of a clip chain 1 and is carried forward to a heating zone. Each clip chain passes, on its return path, through cooling duct 2 into which air is injected in direction of the arrows, and from which air is exhausted. At the transition point between parallel and diverging clip paths, the ducts are made of flexible material. For thermal insulation, a closed housing 4 may be provided. In Fig. 2 a clip chain 1 running on guide rails 9 supported by 8, and passing through cooling duct 2 formed by double-walled, heat-insulated shield 5, is additionally cooled by water sprays 7 and by tubes 6 through which water is passed.
