Title: Improvements in machines for cutting sheets of paper, cardboard or the like
IPC: B26D5/34
Filed: 1930-07-09
Abstract: 352,252. Cutting paper &c. BIAGOSCH, K., 32, Karl Krause Strasse, Leipsic, Germany. July 9, 1930, No. 20805. [Class 31 (i).] Guillotine machines.-In a machine for cutting a printed sheet into labels &c., the work is fed to a cutter by means of a clutch held in operative position by a detent, and the detent is freed when a selected and variable length has been fed by a light sensitive device or other means. The pile of sheets 2 is fed on a table 1 to a knife 24 by a gauge 3 moved by a band 4 from a worm 6. Operation of a handlever 9 controls clutch arms 15, 30 for a reversible drive. The clutch 10 for the feeding movement is thrown in by a lever 12 actuated by a cam 13 and the arm 15 is held by a detent 16. When printed marks on the edge of the sheet pass under a light sensitive device 39, Fig. 7, the current through the anode circuit of a valve 40 is decreased and a solenoid 42 releases an armature 43 to energize solenoids 18, 21. The solenoid 18 releases the detent 16 which throws out the clutch and the solenoid 21 releases a detent &c. 22 to allow a spring to move' the device 8 to an inoperative position. The detent 16 closes a contact 25 to energize a solenoid 26 to actuate the knife 24 through a rod 45. When the knife reaches the top of its stroke a cam 27 actuates the rod 28 to reposition the device 8 and the cam 13 actuates the lever 12 to re-engage the clutch for the next feed movement. A cam 29 on the wheel 14 breaks the circuit in the solenoid 26 of the knife-actuating clutch. When the gauge 3 reaches its forward position a master switch is opened and the gauge is moved to its starting position by actuation of the lever 9. In a modification, the sheet may be printed with electrically conductive metallic colours which may close contact between feelers in the circuit of the solenoid 42, Fig. 8, not shown. In a further modification adjustable contacts on the pulley may be used instead of the feelers. In a further modification the detent 16 is released mechanically by adjustable abutments on the pulley engaging a lever, Fig. 5, not shown.

Title: Improvements in apparatus for positioning an object with respect to a reference datum
IPC: G05B19/27
Filed: 1957-07-04
Abstract: 822,102. Machine-tool details; drilling. GENERAL ELECTRIC CO. July 4, 1957 [July 5, 1956], No. 21183/57. Class 83 (3). [Also in Group VIII] Apparatus for positioning an object, such as a printed circuit board 1 beneath a pin-placing or a hole-punching tool 4, comprises a rack 32 having square teeth and lands and disposed parallel to a direction of movement of the object, a number of latches on an assembly 8 movable with respect to the rack, and means to engage a latch with the rack. The work-table 2 is moved by rods 6 and 7, the control of the former only being described. The rod 6 is moved by an hydraulically-operated piston 9 under the control of a tape 15 which may be read by spring fingers making electrical contact through holes in the tape. The tape selects a required latch in the assembly 8 and a required commutator segment 19. The latches determine the amount of movement in 0.1 inch increments up to 0.8 inch and the commutator segments determine how many additional units of 0.8 inch of movement are required. (The selection of a unit of 0.8 inch is to suit a binary coded tape.) The tape also opens a valve 12 so that the piston 9 moves until a brush 21 corresponding to the energized latch engages the selected commutator segment. At such time, a circuit is completed to operate a solenoid valve and allow compressed air from a source 30 to force the latch into engagement with the rack, thus stopping the movement. The selected brush 21 engages the selected commutator bar before the latch engages a tooth in the rack so as to operate a throttle valve 13 and slow down the table movement. Each latch has a bevelled end and its longitudinal movement may serve to operate a switch to initiate an operation. The apparatus may also be used for drilling, shearing, bending or assembling-machines. The rack may be movable instead of the latches.

Title: Improvements in or relating to vehicle cleansing apparatus
IPC: B60S3/06
Filed: 1956-07-10
Abstract: 802,539. Washing vehicles, brushes. COX, R. E. July 8, 1957 [July 10, 1956], No. 21282/56. Classes 19 and 138(1). Vehicle cleaning apparatus comprises an elongated member 25 with one or more brush elements 29 connected thereto, means for rotating the member bodily about an axis parallel to its length and exterior to itself, and means for reciprocating said member in a direction parallel to its length, the combined motions resulting in rotation of the outermost ends of the brush elements in a plane inclined to the axis about which the member 25 rotates. Two such units are employed in practice, a vehicle passing slowly between them. As described, each unit has a wheeled base 10 with an adjustably tiltable platform 11 carrying a semi-circular cowling 12, spray pipes 13, and a revolvable shaft 15 adapted to be driven via pulleys 16 by an electric motor and carrying elongated members 25. The upper and lower ends of the shaft are supported alike in bearings with protective covers 38 and carry driving arms 17 having portions 18 connected by springs 19 to projecting spigots 20 mounted on a driving member 21 which is ring-like and has a ball race 22 the inner race of which is secured to an upwardly-extending bracket 23 mounted on plate 24. The outer race of ring member 21 is provided with the diametrically arranged spigots 20, these latter being mounted to be rotatable with respect to the outer race about an axis which is radial of the member 21. The angle of oritentation of member 21 with respect to the shaft 15 is fixed, but it may be arranged to be adjustable. At the outermost end of each spigot 20 is connected an elongated member 25 extending parallel to the shaft 15 and having secured thereto a plurality of bristles 29, e.g., of nylon, extending laterally outwards parallel to the plane of rotation of ring member 21. Thus rotation of shaft 15 rotates the outer race of member 21 in its own plane and about an axis inclined to the shaft 15, so that the members 25 and their attached bristles not only rotate about shaft 15 as axis but also reciprocate along a direction parallel to the said shaft, so cleaning vertical beadings &c. on a vehicle. To prevent bowing outwards, the members 25 have spaced sets of straps 35 attached to the shaft 15. Specification 763,069 is referred to.

Title: Improvements relating to the production of plastic compositions
IPC: C08L27/06
Filed: 1943-12-22
Abstract: A process for producing plastic compositions from a vinyl halide polymer or copolymer, in which hydrocarbons of molecular weight 200-800, and having initial and final boiling points within 250-800 DEG  C. at 760 mm. Hg pressure, and a high carbon content (at least 0.6 atoms of carbon per atom of hydrogen) and containing up to two unsaturated linkages per molecule, are extracted from mineral oil fractions or residues with a selective polar solvent or mixture of selective solvents, the extracted hydrocarbons being air-blown at 150-300 DEG  C. for up to 50 hours or more, and the treated hydrocarbons then incorporated in the polymer or copolymer with or without a known plasticizer. Polyvinyl chloride and copolymers of vinyl chloride are mentioned. Dibutyl phthalate is the only specified known plasticizer.  The mineral oil fractions are first extracted with a selective polar solvent or mixture, the extract distilled to recover the hydrocarbons which are air-blown.  The selective polar solvents are sulphur dioxide, alcohols, furfural, phenols or a mixture of sulphur dioxide and benzene.  The extract hydrocarbons may be further processed, e.g. by distillation, partial absorption on porous earths or precipitation by solvents, to render them lighter in colour.  The resulting compositions have good low temperature resistance and electrical properties.  In examples (1), (3) and (5), the preparation of the fractions by extraction with sulphur dioxide and benzene and air blowing is described.  (6) The electrical properties of a composition comprising polyvinyl chloride, dibutyl phthalate and the air-blown extract hydrocarbons are compared with those of a similar composition, but containing extract hydrocarbons not air blown, and (2) and (4) as for (6), but the compositions including also lead silicate and ethyl palmitate.
