Title: Improvements in high frequency signalling systems
IPC: H01Q15/02
Filed: 1931-11-27
Abstract: 392,962. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.-(Assignees of Materiel Telephonique ; 46, Quai de Boulogne, Boulogne, France.) Nov. 27, 1931, No.32919. Convention date, Jan. 21. [Class 40 (v).] Relates to systems for handling wave-lengths of the order of decimetres down to the infra-red. The oscillator, which may be a doublet of the type described in Specification 352,052, is associated with a reflecting or refracting element designed to increase the efficiency of transmission and reception. As shown in Fig. 2, the oscillator 1 is located at a point which is the focus of the main parabolic reflector 1 and the centre of an auxiliary spherical reflector 2<1>.. In Fig. 3, a plane grating or " zoneplate " of concentric rings 15 .. 18 serves to transfer a divergent into a parallel beam, or vice versa. The dimensions of the rings are determined by concentric circles 1a, 1b, 1c, &c. where ab=bc=cd=a half wavelength. The diffraction grating may be replaced by an equivalent reflecting grating. The grating may be used in combination with a spherical mirror such as 2<1>, Fig. 2, or it may be backed by a plane mirror which serves to return rays that pass through the open zones of the main grating. Fig. 7 shows a paraboloid reflector having a central aperture BC, on the far side of which is located a thermal couple 1<1> used to measure the field strength. The size of the central aperture is determined by making 1B1<1>-1A1<1>=#/2. The feed conductors for the valves may pass through the central aperture to the transmitter or receiver. Fig. 8 shows an installation comprising the features shown in Figs. 2 and 7. Here the field strength is measured by a thermo-couple or wave-meter 26 located at the conjugate focus. In Fig. 9 the radiation from an oscillator 1 is directed upwards by a reflector 2 to a plane mirror 2<11> situated at the top of a tower, so as to project the beam from an elevated point, thereby increasing the " optical " range. An intermediate mirror 2<1> may be used to deflect a portion of the radiation towards a wave meter or other indicator of field strength. The elevated mirror 2<11> is rotatable about the vertical axis. Fig. 11 shows a series of coaxial oscillators 1 .. 1<111> associated with gratings or zone plates 20 .. 20<111> and a mirror 2<1>. Each oscillator may be modulated by independent signals S1 .. S1<111> all of which are multiplexed on the final beam of radiation. In the Specification as open to inspection under Sect. 91 a two-way system is described, Fig. 3 (Cancelled), in which each of the receivers 13, 12<1> is located in the shadow of its local transmitter 12 or 13<1>, so as not to be affected by the local radiation. This subjectmatter does not appear in the Specification as accepted.

Title: Method of and press for compacting materials in powder form to produce pieces to be sintered
IPC: B22F3/02
Filed: 1972-07-14
Abstract: 1395180 Compression moulding powder SCHWELMER EISENWERK MULLER & CO GmbH 14 July 1973 [10 Aug1971] 33127/72 Heading B5A Powder is compacted, prior to sintering, in a mould 51, 52 by a piston 21 which first enters the mould at a relatively slow speed to compact the powder and cause it to cohere, the plunger then being withdrawn and driven into the mould at a relatively high speed to impact the powder and further compress it. The plunger is carried by a plate 36 which is guided by rods 37 in cylinders 37 on to which nuts 41 are screwed to provide adjustable stops. The mould is filled with iron powder from an articulated conduit (not shown). The initial compaction and withdrawal of plunger 21 is controlled by a cam 32 which operates a lever 28 having a pin 27 engaging between flanges 26 of a shaft 24 which carries the plunger. A capacitor is then discharged through coil 34 to repel plate 36 and hurl the piston against the powder. Air is maintained in cylinders 37 to assist in raising the plunger 21 during withdrawal and after compaction. The top half of the mould is raised by a cam 33 operating lever 64 to cause two plates 57, 59 connected by rods 58 to slide relative to the fixed frame 10. A plunger 69 is provided in the lower half 52 of the mould and operated in synchronism with the plunger 21 by a similar cam and lever mechanism 77, 73 and coil 34. The upward movement of piston 69 is limited by its shoulder 86 engaging a threaded sleeve 83 which is adjusted by a worm 88. After compaction and raising of the upper plunger and mould half the lower plunger rises to eject the compacted article 54 from the mould half 52. A further cam 99 operates a lever 97 to pull a link 94 which is attached at the rear, as shown, to a ring 91 to rotate the ring and unlatch pins 106 of plate 81. This permits the plate 81 and thus mould half 52 to rise with further movement of the plunger 69 and lift the article off the core.

In a waffle baking machine, in which the baked product emerges, from between successive pairs of heated plates 3, 5, in a continuous strip 21, to be cut into waffles by knife 20, the plates 3, 5 are paired at a charging station, during the dwell period of an intermittent motion, by which they move through the baking zone. The lower plates 3 may be linked to form an endless conveyer 2, for separate upper plates 5, which is driven by a Geneva mechanism (Fig. 2, not shown) to provide the step-wise advancing movement. The dwell period is further used to dispense a portion of dough mixture to each plate 3 from dispenser 17, to operate knife 20 and to feed an upper plate 5 into the bottom of stack 14 (Figs. 13-15 not shown). Plates 5 are shunted from the top of stack 14, along a return path, by a cam-operated walker beam (Figs. 3, 4, 11 and 12, not shown) and drop into the top of stack 10. The vertical movements of stack 10 are controlled by a cam-operated mechanism (Figs. 5-10, not shown). The plate conveying arrangements may be varied so that both paths are in the form of separate plates. The construction of plates 3 and 5 is described in detail (Figs. 16-18, not shown). Instead of using a knife 20, the waffle may, alternatively, be severed by a snap freeezing unit.
