Abstract: 1,229,039. Filter presses. L. GEPGYAR. 24 July, 1968 [27 Sept., 1967], No. 35409/68. Heading B1D. The liquid content of a filter cake is decreased by providing the filter chamber with a pressure member such as an elastic pipe arranged spirally or in zig-zag fashion, or a pair of justaposed elastic diaphragms which are sealed together in places to form cells, the pressure member being expanded by a pressure fluid, such as compressed air, whereby mutual displacement of the particles of the filter cake takes place Figs. 2 and 3 show one filter chamber 4 of a filter press comprising filter cloths 5, frames 1 and plates 2 movably arranged on a supporting structure (not shown). A spirally-arranged rubber pipe 3 is disposed in chamber 4 between struts 6. The inner end of pipe 13 is hermetically closed by plug 14. The inoperative position of the press is represented by A in Fig. 2. When a suspension of solid particles in liquid is pumped in through channels 7 and 8, the liquid penetrates cloths 5 and filtrate leaves through channels 11 while wet cake 12 builds up in chamber 4 whereby pipe 13 is compressed (position B). When chamber 4 is full of cake, the supply of suspension is discontinued, compressed air is introduced through pipe 13 into pipe 3 which expands and compresses the cake 12 in various directions, thereby forcing out liquid therefrom (position C). The pressure in pipe 3 is then released, the frames and plates are spaced apart, and the cake is thrown out by again introducing compressed air into pipe 3 (position D). The outer wall of pipe 3 may be ribbed or knurled, and may be sheathed in filter cloth.

Abstract: 1,229,113. Making rivets; extruding; riveting. E. C. FRAZE. 11 Aug., 1969 [21 Nov., 1968], No. 40052/69. Headings B3A, B3P and B3U. [Also in Division B8] One rupturable rivet 117 of a pair of spaced rivets 115, 117, which are integral with a tearout panel of an aluminium can end and secure a pull-tab 113 to the panel, is formed by squeezing the can end panel between upper and lower coining dies 55 and 57 so that the metal flows radially inwards into a recess 67 in the upper die to form a closed hollow unstaked rivet 59 which is joined to the coined region 73 of the can end by a thin, readily rupturable annular region 79. The tab is then placed over the unstaked rivet, the tab being clamped to the can end by coacting members 85, 87, and a punch 89 utilized to complete the formation of the rivet. The lower coacting member is provided with a projection 93 extending into the rivet to prevent thickening of the region 79 during the punching operation. Prior to the nose end of the tab initiating rupture of the score line 109 defining the tear-out panel on lifting the tab, another score line 127, Fig. 1 (not shown), which extends laterally between the rivets 115 and 117, is ruptured on lifting-the tab so as to vent the can interior to atmosphere. In a modification, Fig. 8 (not shown), the rivet 145 is not ruptured in use, and the rupturable transverse vent score line 173 extends radially inwards of the rivet 145.

Abstract: 1,229,540. Feeding and delivering sheets. SINGER CO. 17 July, 1969 [22 July, 1968], No. 36052/69. Heading B8R. Apparatus for operating upon successive fabric workpieces 21 on a continuous conveyer 11 to automatically orient the workpieces with a predetermined side uppermost, comprises photo-electric detector means 60 responsive only to a workpiece disposed with the predetermined side facing the conveyer, and gripper means operated under control of the detector to grip and lift the leading edge of such a piece so that the conveyer carries forward the remainder of the piece, the gripper being subsequently opened so that the piece is now moved forward by the conveyer with the predetermined side uppermost. The pieces may be fed one by one from a stack and after being correctly orientated proceed to a delivery area 22 where any desired operation may be performed thereon or they may be stacked. The detector 60 includes a photoelectric cell 64 which, when a wrong-side up workpiece is detected, produces a signal causing a valve to be opened and pressure air to be admitted to a cylinder 53 to move downwardly a normally-spring raised piston-rod 52. The rod 52 is connected to a link 50 fixed to a shaft 32 to which arms 34 also are fixed. Bosses 35 on the arms 34 support an air cylinder 37 with an air supply line 38 and the piston rod 39 of which is normally spring-retracted. Connected to the piston-rod 39 is a bell-crank 41 pivoted to the arms 34 at 42. A clamping-plate 44 on one of the arms of the bell-crank 41 can co-operate with the arms 34 to constitute a gripper. Normally, the parts 34, 50, 52 are in the position shown in Fig. 5, but the gripper 44 is open. When a piece 21 with its wrong side uppermost is sensed, the signal generated causes the cylinder 53 to be operated to move the arms 34 and the open gripper 44 into the path of the piece so that the leading edge of the piece enters the gripper. A valve is now opened to cause pressure air to enter the cylinder 37, the valve being controlled by the detector signal via a delay device. Operation of the cylinder 37 closes the gripper 44 so that the leading edge of the piece is held by the gripper. Pressure in the cylinder 53 is now released so that the parts 34, 52 rise to their uppermost position and the conveyer 11 carries the trailing part of the piece 21 beyond the gripper as shown in Fig. 5 until its predetermined side is uppermost. The gripper 44 is now released to allow the re-orientation to be completed by the forward movement of the piece.

Abstract: 1,265,150. Jet propulsion plant; axial-flow fans. ROLLS-ROYCE Ltd. June 20, 1969 [June 22, 1968], No.29883/68. Addition to 1,195, 961. Headings F1C and F1J. In a modification of the variable pitch aerofoil rotor blade arrangement claimed in parent Specification, the gear train for control of the variable pitch parts of the blades includes a system of compound epicyclic wheels. The rotor may be a front fan of a gas turbine ducted fan engine wherein, as described in the parent Specification, the radially inner parts (16), Fig. 1 (not shown) of the fan blades are of fixed pitch and the outer parts (14) of variable pitch. The latter are connected by radial shafts 18 passing through inner blade parts (16) to pinions 20 meshing with a common bevel wheel 22 disposed within the fan hub and carried on bearings from a sleeve 23 which surrounds and is attached to the fan shaft 17. The bevel wheel 22 has a cylindrical extension 24 with a ring of teeth 25 meshing with teeth 26 on a compound epicyclic wheel 27 having further teeth 30 meshing with teeth 31 on sleeve 23. Three or more epicyclic wheels 27 are equi-spaced around the shaft 17 and supported on journals 28 from a carrier member 29 itself supported on sleeve 23. The carrier 29 has pole rings 32, 33 on its inner periphery which co-operate with pole rings 34, 35 on sleeve 23 and on fixed structure 36, respectively, The rings 34, 35 have no electrical connections thereto but the rings 32, 33 can be supplied with electricity through wires 38, 39 and brush and slip ring arrangements 40. Each of the latter comprises a slip ring 41 mounted on the fixed structure 36 and connected through a wire 42 with an electrical supply. Bearing on the slip ring 41 are carbon brushes 43 which are loaded inwardly by springs 44, the loading of which is such that at high rotational fan speeds the brushes 43 lift away from the slip ring 41 under centrifugal force, thus reducing wear and avoiding inadvertent energization of the pole rings. During normal operation of the fan the carrier 29 is locked by poles 32, 34 to rotate with shaft 17. Thus bevel wheel 22 also rotates at the same speed as shaft 17 and pinions 20 do not adjust the variable pitch blade parts (14). If it is required to feather the blades so as to arrest the fan, e.g. in the event of engine failure, poles 33 are energized so as to electromagnetically lock the carrier 29 to the fixed structure 36. Thus epicyclic wheels 27 cause bevel wheel 22 to rotate relative to shaft 17 and drive pinions 20 to feather the outer blade parts (14) until the fan stops. Any chance in conditions causing departure of the fan from this equilibrium state results in automatic readjustment of the blade parts (14) so that the fan once again stops. Should the fan be required to develop reverse thrust, energizing pulses are supplied to poles 32 causing carrier 29 to rotate relative to shaft 17 and thus driving wheels 27, 22 and pinions 20 so that the blade parts (14) move into a reverse thrust position.

Abstract: 1289600 Radar SIEMENS-ALBIS AG 16 Nov 1970 [24 Nov 1969] 54359/70 Heading H4D [Also in Division G4] A distance measuring system has two transceivers, each capable of operating as a main station or a subsidiary station, mounted at opposite ends of a distance to be measured each transmitting a different frequency measuring signal, each producing a difference signal from the transmitted and received signals, the difference signal at the subsidiary station being transmitted back to the main station wherein by phase measurements involving both difference signals a partial range measurement is produced and on production thereof the measuring signal is switched off and each station has means to detect said switching off to change the measuring frequencies and produce a further partial result, an overall result being produced from said partial results. In the main station oscillator 11 produces a signal of frequency f01 which modulates a carrier wave which is transmitted via TR device 15. Signals from the subsidiary station are received and passed through device 15 and mixed with a portion of the transmitted signal. The received signal contains modulation components due to the subsiding station measuring signal S02 and difference signal S2. Detectors 18, 19 select the signals f01-f02 and S2r and the phase difference therebetween is measured in meter 20 by a pulse counting technique involving the setting and resetting of a bi-stable. The resetting thereof closes switch 12. Markers 21, 22 detect the cessation of the signals S1 and S2r and logic 24 acts to step on a motor driven rotary switch to provide a new measuring frequency. In the subsidiary station oscillator 31 produces the measuring signal of frequency f02, below f01 which modulates the transmitted carrier. The difference signal produced by mixing the transmitted and received measuring signals are selected by detector 38 and marker 41 indicates the presence thereof opening gate 47. The difference signal is used to control the oscillator 31 frequency to produce the correct difference frequency and when this is achieved a signal passes through gate 47 to open switch 32 which allows the subsidiary station difference signal also to modulate the transmitted carrier. Detector 39 selects this reported back signal from the mixer 36 output and marker 42 indicate its presence. As in the main station the cessation of the main station measuring signal f01 is detected and used to switch to the next measuring frequency which is this time above the main station emasuring frequency The partial range results thus obtained are combined in a known way to produce an unambiguous range measurement.
