Title: Improvements in or relating to feeding devices or fingers for lathes and like machines
IPC: B23B13/12
Filed: 1943-08-06
Abstract: 575,258. Bar-feeds. STEVENS, A. H. (Slovak, A., and Green, F. L., [trading as Green Mfg. Co.]). Aug. 6, 1943, No. 12767. [Class 83 (iii)] A bar-feed suitable for automatic screw machines has a sleeve of resilient material, such as rubber, or synthetic rubber, such as that sold under the Registered Trade Mark "Buna," or material such as Kogene, which may be adjusted by axial pressure to grip the bar with the required pressure. In one form, a sleeve 6 of rubber or artificial rubber is enclosed in a tube 7 between an inturned flange 11 of the tube and a screwed sleeve 23 which is adjustable within the tube to vary the pressure on the sleeve 6 and so adjust the grip of the latter on the bar 10, the resilience of the sleeve 6 allowing for the gripping of bars over a considerable range or for gripping bars of non-circular section. The sleeve 6 may have metal ferrules 15, 19 attached to its ends to take the end thrust, the apertures in the ferrules being only slightly larger than the largest bar to be gripped, or flat washers may be attached to the end surfaces of the sleeve as by vulcanization. The tube 7 has an aperture 21 and the sleeve 23 an axial groove 22 for relative rotation of the sleeve and tube by a spanner, and the sleeve 23 is attached to the feeding tube 8 of the machine by an internally and externally screwed sleeve 24. Alternatively, the sleeve 6 may abut an internal shoulder in the tube 7 and be adjusted by a hollow plug screwing in the open end of the tube. In a modified construction, a sleeve 33, Fig. 7, of oil-resisting synthetic rubber is adjusted within a tube 31 by a sleeve 32 screwing therein and locked after adjustment by the hooked end 42 of a spiral spring 45 lying in an axial groove 43 of the sleeve 32 and pressed axially into one of a series of recesses 44 in the end of the tube. Rotation of the tube and sleeve is effected by a hole 38 in a thickened portion 39 of the sleeve and recesses 40 in the end of the tube.

A kaleidoscope comprises a base member 1 made of a plastics material, having upstanding therefrom a pair of flat members 8 and 9 also made of a plastics material, meeting at an acute angle and mirrored on their inwardly facing surfaces 15, and a plane member 5 rotatable between the base member and the mirrored members, the line along which the mirrors meet lying along the axis of rotation of the plane member. The base member has a cylindrical boss 2 upstanding therefrom by at least the thickness of the plane member which has a counter-sunk region (3) formed at its upper end which the mirrored members engage for support and exact positioning thereof. The mirrored members are pivotally mounted on the base member by means of a pair of upwardly extending apertured lugs 6 which engage horizontally directed pins 13 formed on the mirrored members or provided on a further pair of lugs 11 and 12 which extend from the mirrored portion of members 8 and 9. The base member, boss and lugs may be a single moulding or plastics material e.g. high impact polystyrene, and the mirrored members may be made of such plastics material as polystyrene or PVC, having a reflecting coating e.g. vacuum deposited aluminium on the one side and a pressure-sensitive adhesive on the other.

Title: Improvements in or relating to an apparatus for cutting candy
IPC: A23G3/20
Filed: 1948-05-10
Abstract: 666,633. Endless conveyers. MARS, Inc. May 10, 1948. [July 19, 1947] No. 12772/48. Class 78 (i). [Also in Group V] A cutting apparatus, described particularly with reference to the manufacture of chocolate-coated candy bars, has slitting discs 50, Fig. 2, which slit the candy sheet 51 into strips, adjacent strips 52, 53 then passing respectively to lower and upper slicing stations where they are severed into blocks by knives 54. The candy blocks are discharged from the slicing stations by conveyers moving at a higher speed than the candy strips so that the blocks are separated and are transferred at a single level to a conveyer 58 for a chocolate coating operation. The candy sheet is transferred from the conveyer 47, Figs. 2, 6 on to a roller table 80, the leading edge of the sheet being supported during transfer by a strip feeder 133, Fig. 9, which is provided with a rack whereby it may be moved into operative or inoperative position by a handle 132. The sheet is then cut into strips by knives coacting with a cutting drum 107 which is peripherally grooved throughout its length to form pulleys for two series of V-belts 130a, 136b, Fig. 6, the belts of the series 136a carrying alternate strips of candy to a lower roller table 183a and the belts of the series 136b carrying the interposed strips to an upper roller table 183b. The belts are tensioned by adjustable idler pulleys 149, 159 and are supported by pulleys 164, 162. Guide belts 166a, 166b disposed above the belts 136a, 136b are mounted between the slitting knives and are driven by the shaft 90 which carries the slitting knives. The chain drives for the shaft 90 and for the shaft 108 carrying the cutting drum 107 are independent so that the slitting knives may continue to rotate after the feed of the sheet has stopped, thereby preventing the knives from sticking. Specifications 646,503 and 666,635 are referred to.

Title: Improvements in the automatic frequency control of high-frequency transmitters
IPC: H03J7/04
Filed: 1953-05-14
Abstract: 724,735. Automatic frequency-control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 14, 1953 [May 17, 1952], No. 13525/53. Class 38 (4). A radio transmission system, comprising an oscillation generator stabilized by automatic frequency control and coupled to the aerial by cascade stages, is provided with a search voltage generator which facilitates initial locking of the A.F.C. system, and which at the same time provides means for blocking the transmitter cascade until locking is effected, whereupon the search voltage vanishes. The search voltage may give an audible warning in a monitoring telephone, so long as stabilization has not been effected. Fig. 1 shows a block diagram of the system, the oscillation generator 1 being stabilized by mixing the output in a phase comparer 3 with that of a reference source 2 which may be a pulse source. The mixer output passes through a filter 4 to a reactance tube 5 to stabilize the frequency of the generator 1 at that of the reference source 2 or at the nearest harmonic thereof. The reactance tube is reciprocally coupled with an amplifying tube 6 to constitute a low-frequency R.C. generator, which supplies a search voltage to the reactance tube to facilitate initial locking, but becomes inoperative as soon as locking is effected. The search voltage is rectified at 13 and supplies a negative blocking voltage to a stage 10 between the oscillator 1 and the aerial 12, so that radiation is prevented until stabilization has been effected. The rectified voltage is also applied to an amplifier 14 which supplies an operating D.C. voltage to a relaxation oscillator 15 giving a warning note in a monitoring telephone 16. The output of the main oscillator 1 may be mixed at 7 with that of an adjustable interpolation oscillator 8 to provide stabilized frequencies intermediate between successive harmonics of the pulse source 2. The mixer output passes through an adjustable band-pass filter 9 to the amplifier stages 10, 11. The Specification includes a circuit diagram (Fig. 2, not shown) in which the elements 1 to 8 are as described in Specification 721,106, the band-pass filter 9 comprises coupled tuned circuits and the stage 10 comprises a heptode valve with the blocking voltage derived from the rectifier 13 applied to the third grid. The rectified voltage is also amplified in a triode valve 14 which may be in the same envelope as the heptode valve 10, and which supplies the driving voltage for the glowdischarge relaxation oscillator 15. Specification 685,991 also is referred to.
