Title: Improvements in or relating to aerial systems
IPC: H01Q19/13
Filed: 1931-09-11
Abstract: 389,142. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, and MATHIEU, G. A., 3, Mayfield Gardens, Shirehall Park, both in London. Sept. 11, 1931, No. 25563. [Class 40 (v).] An aerial system consists of one or more reflector units 1 each comprising a plurality of open-ended rod-oscillators 4 supported centrally on a single " backbone " conductor. As shown in Figs. 1 and 3, the rod-oscillators 4 are mounted centrally on lines 1 which are bent into a parabolic curve and held in position by wooden blocks 2 mounted on quartz-glass insulating rods 3, the whole being carried on an adjustable trestle support 7. Small metal tubes may be fitted over the ends of the rod-oscillators to adjust their effective length. When several units are set in close proximity, the rod-oscillators may be merged into a series of continuous transverse members. The aerial system serves to reflect and concentrate the energy from an oscillator 5 at the focal point of the system, as shown in Fig. 3. The rod-oscillators may be fitted with small end-discs which are aligned with those on the adjacent unit to form a capacity coupling, whereby a uniform current distribution is obtained over the whole aerial system. In an aerial system of the form shown in Fig. 1, the radiation is horizontally polarized. By rotating the aerial structure through 90 a vertical lypolarized wave is produced, and the combination may then be used for diplex working on a single wavelength. The supports 1, the rod-oscillators 4, and the members 3 may be made hollow, and steam or hot water circulated for melting deposits of frost or snow. Or electric heating elements may be inserted in the hollow members for the same purpose. For broadcasting a number of units 1 may be arranged to face outwards from a common centre, as shown in Fig. 4, and energized in phase so as to ensure a uniform distribution of energy. Or the system may be energized in sequence to radiate a rotating " beam," which may be suitably modulated for navigational purposes. A number of straight " fishbone " units may be arranged side by side and energized cophasiably to give a beam effect. Specification 252,272, [Class 40 (v), Wireless signalling &c.], is referred to.

Condensers comprise a plurality of individual condenser units each consisting of a stack of alternately arranged sheets of conducting and insulating material and a pair of U-shaped clip or clamping members engaging the opposite ends of the stack and forming the terminal members therefor, arranged in spaced relationship between a pair of plate members or within a framework or casing and means for controlling the temperature to prevent overheating. In Fig. 1, units 3 are mounted between top and bottom plates 1. 2 and surrounded by a coil 4 containing a cooling or refrigerating agent, such as water, whereby the temperature of the condenser may be kept within required limits. Each unit comprises a body of interleaved conducting and insulating sheets f, m, carried in clamps 6, Figs. 3 and 5, the ends of the clamps having beads 7 for receiving the plates of one polarity and for insertion into clips 8. The. ends of the beads 7 are corrugated for purposes cf strength and the adjacent edges of the clamps are serrated at 12 to permit discharge in the event of excessive potential being applied. The outer screws 9 of the clips 8 of the top plate are turned up into bush. ings 15 threaded to receive a binding nut 19, while the inner ones are connected by a plate 21 having an aperture 22. The bottom plate clips are connected in pairs by plates 20 so that combinations of connections for the units 3 may be obtained. In a modification, there may be six units 3, the inner four being connected in pairs by two plates 21, and the whole is surrounded by a dasing perforated to permit circulation of a cooling agent. In Fig. 2, the bottom plate has a trough 25 to contain an evtporable liquid into which dip strips of fibrous or absorbent material 26 which absorb and evaporate the liquid. The casing is perforated to permit circulation of a cooling agent. In Fig. 9 the beads 7 are suspended from bolts 28 secured in the top plate, and also carry studs 30 with adjustable safety discharge screws 32 for protecting the condensers. In Fig. 6, opposite ends of the unit are clamped by channel members 35 while the lower end rests in a recess 34. Each clip is connected to a terminal part 36 and a number of connected clips may be formed out of a strip of metal for connecting units in parallel. A cooling coil, with or without absorbent strips, may be employed in. this last modification.

Abstract: 737,435. Photographic image-receptive assemblage. INTERNATIONAL POLAROID CORPORATION. Sept. 18, 1953 [Sept. 19, 1952], No. 25811/53. Class 98 (2). The assemblage comprises an image-receptive sheet having an image-receiving section separated from residual sections on opposite sides thereof by perforations extending across the sheet, and a superposed masking sheet with an opening aligned to define an image-receiving area. The masking sheet may be wider than the image-receptive sheet so as to overlap the edges thereof and a container of liquid processing composition may be attached to one of the residual sections. A superposed photo-sensitive sheet may be adapted to adhere to the assemblage when wetted by the processing composition. As shown the image-receptive sheet 20 has imagereceiving sections 26 separated from residual sections 30 by pairs of perforations 32, superposed masking sheet 34 with openings 36 is joined by a strippable bond to the image-receptive sheet 20, and processing-liquid containers 38 are fixed to masking sheet 34 in alignment with residual sections 30 by adhesive strips. 40. The various materials concerned are of the nature described in Specification 684,592 and are for the purpose of producing, in conjunction with an exposed photo-sensitive sheet, direct positive images in sections 26. In practice photo-sensitive sheet 10 with frames 16, and the assemblage with openings 36 in registration with the frames 16, are passed between rollers 44, 46, of which the former is provided with a pair of shouldered end portions 48, to rupture a container 38 and spread the processing liquid, contact of the latter with sheet 20 is, however, restricted to image-receiving area 28 by the overlapping masking sheet 34 and excess of processing liquid is retained at a trapping region adjacent to a pair of crush-resistant projections 68. After development of the negative image in frame 16 and production of the positive in area 28 the image-receiving section 26 is torn out with the aid of finger-hole 54 and perforations 56 extending thereto. To preserve continuity of the materials after removal of a section 26, residual sections 30 may be caused to adhere to the photo-sensitive sheet 10 by a pair of projections 64 extending through apertures in the masking sheet 34 or by adhesion of elements 62 to the photo-sensitive sheet. Specification 703,231 also is referred to.

Title: Rotary positive-displacement gas pump
IPC: F04C18/20
Filed: 1978-05-31
Abstract: The Roots pump has two parallel pistons (1, 2) which roll on one another without contact. At least two toothed bars (3) are arranged symmetrically at the perimeter of the main piston (1) and engage corresponding indentations in the counterpiston (2). The compressed gas is expelled, through discharge orifices arranged in the toothed-bar (3) flanks running forward in the delivery direction, via bores (11) in the main piston (1) and via the tubular shaft (12). Close behind the discharge orifices, outlet valves may be provided. The Roots pump can be designed both for dry running and as an oil-sealed pump. A higher pressure ratio and a lower clearance volume than hitherto can be achieved. If the pump is provided with a pre-stage equipped with Roots-type rolling pistons, it can be used economically as a vacuum pump for substantial amounts of gas and be used, for example, instead of the hitherto conventional steam jet ejectors. <IMAGE>

[Also in Divisions B1, B5 and F1] An electrically controlled apparatus for metering quantities of flowable material into a common mixing chamber and thence into a mould is characterized in that it has an hydraulic ram supplied through an electrically-controlled valve and oscillating a member 3 to which are attached reciprocating pumps 4, 5 that draw from separate sources. Movement of the member 3 actuates the pumps and displaces, via linked rods 7, 7<SP>1</SP>, a contact (9) to engage a bank of contacts (10a-10e), Fig. 2 (not shown). According to the size of the mould to be filled, one of the contacts (10a-10e) is energized by one of switches 14a-14e mounted on a control panel, and connection with the sliding contact (9) operates the valve to stop the pumping.
