Title: Improved pneumatic pulsator for use with milking machinery
Inventor: KINGSTON JONAS ARTHUR COLLINS
IPC: A01J5/10
Filed: 1959-09-18
Abstract: 967,722. Milking machines. GASCOIGNES (READING) Ltd. Sept. 14, 1960 [Sept. 18, 1959], No. 31844/59. Heading A1M. The pulsator of a milking machine comprises a reciprocating piston-type valve 15 for controlling the application of pneumatic pulsations to the teat cups 40, the reciprocations of the valve 15 being in turn controlled by a ported valve 12 which is rotated by means of a turbine wheel 4 mounted in the path of air drawn into the pulsator housing during the milking operation. The valve 12 is suitably ported to alternately connect the lower end of the reciprocating valve housing 18 with the vacuum chamber 26, and with the exhaust passage 35, whilst the upper end of the housing 18 is in continuous connection with the said vacuum chamber 26. Thus, as the valve 12 rotates, the valve 15 reciprocates to alternately connect the liners of the teat cups 40 with the vacuum chamber 26, and with atmosphere, the latter connection being via the turbine wheel chamber and the passage 22. Operation of the pulsator is initiated by opening valve 27 to connect the turbine wheel chamber with the vacuum chamber 26, thereby causing air to be drawn into the pulsator past the turbine 4, and thereafter the air periodically drawn into the teat cup liners causes the turbine wheel to continue its rotation.

Abstract: 1,240,924. Frame saws. THOMAS ROBINSON & SONS Ltd., and R. H. BUCKLEY. 9 June, 1970 [25 June, 1969], No. 32001/69. Heading B5L. In a reciprocating saw comprising a plurality of saw blades 48, Fig. 2, mounted side-by-side and substantially upright in a frame 43 which is adapted for up and down reciprocation, means are provided to cause the frame to recede in the timber feed direction in the return stroke of each reciprocation and to advance contrary to said feed direction in the cutting stroke of each reciprocation, the locus of any point on the frame during the reciprocation approximating to an ellipse. As described the frame 43 comprises vertical bars 44 which are journalled on enlarged eccentric portions 35, 38 of crosshead shafts 29, 28 respectively journalled in vertical bars 23 of a carriage 22. A connecting rod 32 has one end 33 driven by an eccentric and its other end 34 is fixed to the portion 35 of shaft 29. Movement of the rod 32 causes the carriage 22 to slide up and down on rods 20 supported on a framework 10, so as to reciprocate the saw frame 43 vertically, and simultaneously causes the shaft 29 and the shaft 28 which is linked thereto to oscillate so that the enlarged portions 35, 38 cause the saw frame to reciprocate horizontally in correlation with the vertical reciprocation. Each saw blade 48 has one end secured to a spindle 49 and its other end apertured to receive an eccentric boss of a disc 51 which enables the blade to be individually tensioned. The discs 51 are mounted on a spindle 50 carried by a frame 54 movable by bolts 59 to tension the blades as a unit.

Filed: 1971-07-08
Abstract: 1316924 Semiconductor devices SIEMENS AG 8 July 1971 [20 Aug 1970] 32058/71 Heading H1K Ohmic contact is made at one face of a monocrystalline semiconductor wafer to zones defining a PN junction beneath an insulating layer, by aperturing the layer at contact areas, depositing suitably doped polycrystalline semiconductor material only in the apertures, depositing metal overall and selectively removing it by photoetching to define electrodes. Deposition of the polycrystalline semiconductor which takes place at a wafer temperature <1000‹ C. is restricted to the apertures either by pre-treating the insulating layer, e.g. with dilute hydrofluoric acid to eliminate seeding centres, or by using a transport reaction in which the wafer is placed on the source so that the insulating layer serves as a mask. The semiconductor wafer may consist of silicon, germanium, or A III  B V  compound, the insulating layer of silica, alumina or silicon nitride and the contact metal of aluminium. As described the contacts are made to the zones of a diode and a planar transistor respectively.

Title: "machine for continuously cutting up plastic material"
IPC: B26D1/00
Filed: 1958-10-10
Abstract: 849,866. Cutting extruded plastic materials. MAZZONI S. p. A., G. Oct. 10, 1958 [Jan. 22 1958; June 3, 1958], No. 32374/58. Class 87(2). A machine for cutting plastic material 3 as it advances from an extrusion machine on a conveyer 4 comprises spaced blades 7 mounted on a linkage in a closed loop and a non-rotary guide 7 for shortening or extending the linkage to change the length of the cut. Pins 12 pass through round holes in the links 10 and slots in the links 11 and also through the ends of pairs of connecting links 17, 18 which are joined at their other ends by pins 19. Rollers on the ends of the pins 12 run between fixed guides 14, 15 along the top and bottom runs of the chain. Rollers on the ends of the pins 19 run beneath a guide 21 above the bottom run of the chain, the guide 21 being movable by screw-threaded rods 27 operated through worm gearing by a hand wheel 23. Decreasing the distance between the guides 21 and 14 will cause a flattening of the chain and, owing to the rigidity of the links 17, 18, the pins 12 will be moved further apart and hence also the blades 7 conversely, moving the guide 21 away will move the blades nearer together. Compensating movement takes place of the the pins 12 in the upper run of the chain. The chain system is duplicated, the chains passing round pairs of wheels 8, 9 at the ends. The wheels 8 are driven by a motor (not shown) and have peripheral rings 32, e.g. of rubber, which engage metal rings on the pins 12 and impart motion to the chains, assisted by the action on the blades 7 of the material being extruded. The inclination of the cutters may be varied by moving the sides 16 on which the guides are mounted ; also the shape of the conveyer 4 may be varied.
