Title: Improvements relating to slicing machines
IPC: B26D7/06
Filed: 1936-10-20
Abstract: 483,489. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (Maatschappij van Berkel's Patent N.V.), and BERKEL, C. F. M. VAN. Oct. 20, 1936, No. 28488. [Class 28 (ii)] In a slicing-machine, the fixed adjustable abutment 24 for actuating the slicefeed mechanism is adjusted by means located adjacent to the slice-receiver through a pressure transmitting device including a series of abutting elements constrained to move in a determinate path, which ordinarily would be partially curved. As shown, the invention is applied to a reciprocating carriage machine, and the abutting elements comprise metal balls 34 confined in a tube 28 one end of which is received in a block 27 on the base 13. The tube extends from the block 27, across the base, to the slice-receiver 26, and a plunger-like rod 30, having a rack extension meshed with a pinion 32 actuated by an adjusting knob 31, is slidable in this fixed end of the tube and transmits pressure through the balls to a rod 29 likewise slidable in the tube and carrying the abutment roller 24. The rod 29 is maintained in contact with the balls by the reaction of the striker 22, although, if desired the rod may have a return spring. A resilient connection may be provided between the knob 31 and the abutment 24, e.g., a torsion spring 32b interposed between the knob and the pinion shaft 32a. This spring would be strong enough to resist the impact of the striker 22 and to force the abutment 24, when free to move, into its proper position according to the slice-thickness setting of the knob, but would not be strong enough to force also the striker 22 and associated feed mechanism to move should the striker be in contact with the roller 24 when the knob is turned. The striker 22 is secured to a pulley 21 connected to a flexible band 20 which is secured to a pulley 19 carrying the pawl lever 18. The band 20 is maintained taut by a spring acting on the pulley 19. Specification 483,701 is referred to.

Abstract: <PICT:0816034/III/1> <PICT:0816034/III/2> <PICT:0816034/III/3> A calcium nickel phosphate catalyst, suitable for use in the dehydrogenation of olefins, containing 4-6 carbon atoms to form diolefins, is prepared by collecting and water-washing a Ca, Ni, PO4, precipitated from a non-acidic aqueous medium and drying by (i) heating to reduce the water content to 40 to 75 per cent, preferably between 60 to 70 per cent by weight, (ii) mechanically working and adding water to maintain a 40 to 75 per cent by weight water content to replace water losses due to continued heating, (iii) heating and mechanically working the material to reduce the water content, and (iv) heating to dryness. Stages (ii) and (iii) are continued until a test portion, removed from the mass, dried and ground, has a bulk density of 0.4 to 0.6 gm./c.c. and 0.5 to 0.7 gm./c.c. respectively. The water added to stage (ii) to maintain a 40 to 75 per cent water content is preferably in the form of a slurry of freshly-precipitated calcium nickel phosphate containing, at least 75 per cent by weight of water.  To form catalyst pellets of bulk density 0.95-1.1 gm./c.c. from a single pressing of the dried and ground calcium nickel phosphate a rotary drum 11, Fig. 1, with kneading and lifting bars 12 and gas heating burner 13 works, heats and dries an aqueous slurry of the material according to stages (i), (ii) and (iii) into a dough-like mass which breaks down into rounded lumps (Figs. 2 and 3) of 30-35 per cent (wt.) water content and 1/2 inch to 1 1/2 inches diameter.  Heating to dryness can then be continued without mechanical action in, for example, open trays and the dried material ground to a powder of 12-80 mesh screen size.  2 per cent lubricating graphite is incorporated into the powder to be pelleted which is later removed by passing a mixture of steam and air at 450-750 DEG C. through a bed of the pelletized catalyst.  Examples given also describe the addition of a minor amount of chromium oxide into the powder before it is pressed into pellets.  Specifications 634,391, 634,580 and 679,082 are referred to.

Filed: 1957-09-12
Abstract: 868,078. Radar. HUGHES AIRCRAFT CO. Sept. 12, 1957 [Nov. 23, 1956], No. 28832/57. Class 40(7) In a short range M.T.I. radar system, having a high pulse repetition frequency, "second time round" echoes are avoided by changing the frequency after each pulse. The beam of a step scanning antenna is positioned in a direction determined by the frequency of the transmitter pulse and the receiver local oscillator is maintained at a constant frequency until immediately prior to the succeeding transmitter pulse. After a predetermined interval, a pulse is transmitted at the same frequency in the same direction as a previously transmitted pulse and space-decorrelation of the clutter signal is minimized. The M.I.I. pulse pairs used for cancellation are spaced four pulses apart to avoid the "second time round" echoes. The video signals received in response to each transmitter pulse are delayed four repetition periods and subtracted from corresponding signals received from the next transmitter pulse in the same position, in addition, the delay line used for this is also used to accurately time space the M.T.I. pulse pair. As shown, the frequency scan antenna 20 is energized from the exciter 12 controlled by the master pulse generator 24, in unit 10, and a beam is radiated in a direction determined by the pulse frequency. The sweep signal of ing to the pulses of each series are compared to eliminate second time round echoes, both in respect of same beam position. Specification 847,253 is referred to.
