Title: Filter press
IPC: B01D25/172
Filed: 1967-03-23
Abstract: 1,131,580. Filter press. COMPAGNIE GENERALE D'ELECTRO CERAMIQUE. 23 March, 1967 [28 March, 1966], No. 13882/67. Heading BID. A filter press comprises rails (3), which slidably support filter plates 4, and rails 10 which carry a wheeled trolley comprising two side plates 11 between which the plate spreading and cake removal mechanisms are mounted. Each plate 11 has two carriages 15, 16, travelling in horizontal slideways 13, 14 and having retractable fingers 17-20 which engage successive plates 4 so that they are moved apart as carriages 15, 16 separate. The cake on a newly exposed plate is engaged and held by suction applied to cups 24 on a vertically movable support 23 as the plate is moved away (Fig. 3, not shown). As illustrated, the support is lowered and pivoted through 90 degrees, after which compressed air is supplied to the cups and the cake drops on to a pallet 28 on the trolley base. Alternatively, the support moves only in its own vertical plane and released cake falls on to a conveyor belt. Carriages 15, 16 on each plate are geared together and the carriages on respective plates are resiliently coupled to move together. Fig. 5 (not shown) illustrates the operating cycle of carriages and fingers whereby separated filter plates are brought together, sandwiching support 23, then separated to withdraw cake from one of them which is finally brought 'back again to transfer it to the 'emptied' side on the next cycle. A central cylindrical cutter 26 separates and retains the central section of each filter cake. The various movements of fingers, carriages and support 23 are effected by electrically controlled jacks and controlled by a single programme control device.

Title: Improvements in or relating to two-way intercommunication systems
Inventor: NAMENYI-KATZ LASZLO
IPC: H04M9/00
Filed: 1961-04-18
Abstract: 947,426. Two-way transmission systems. VECTRON ELECTRO-PHYSICS Ltd. April 18, 1962 [April 18, 1961], No. 14039/61. Heading H4R. In an intercommunication system comprising a station having incoming and outgoing speech channels, a low-pass filter responsive only to signals in the outgoing channel of a frequency below a certain cut-off frequency is effective to control a switch means which then conditions the system for the passage of the outgoing signals and in which the incoming channel is provided with high-pass filter means so as to prevent acoustic feedback signals from operating the switch means. As shown, a portion of the speech signal from microphone M is passed via a low-pass filter LPF (cut-off 500 c.p.s.) to a trigger circuit TR2. Similarly, a portion of the speech signal on a line LP is directed via a rectifier unit R1 to a trigger circuit TR1. It is arranged that signals from TR2 have priority in the control of switch means SAC (which may be an electro-mechanical or electronic, e.g. a valve or transistor switch), thereby to condition the switch for outgoing speech. In order to prevent acoustic feedback from. the loudspeaker LS to the microphone M affecting the switch, a high pass filter is included in the incoming channel although this may be dispensed with if the system as a whole has a high pass (500 c.p.s.) characteristic. The above system may be modified so that SAC responds to whichever of the incoming and outgoing signals is the louder, as is described with reference to Fig. 2 (not shown). The latter system includes an inhibiting device which prevents microphone signals as they appear on the line (i.e. simulating incoming signals) from actuating the switch, this inhibitor being described more fully in Specification 946,113. It is also mentioned that the loud-speaker and the microphone may be incorporated as a single transducer.

Abstract: 889,745. Knitting-machines. SINGERFIDELITY Inc, April 22, 1960, No. 14169/60. Class 74 (2). To facilitate the separation of articles knitted in stringwork formation, the separating course is severed at its beginning and end whilst the articles are continuing to be produced on the machine. The articles can subsequently be separated by merely withdrawing the yarn of the separating course. As described in connection with a circular machine having swinging dial needles, a rod-like member 27, mounted at its lower end to rotate with the needle cylinder, extends upwardly within the cylinder and is curved at its upper end to conform with the configuration of the upper end of the cylinder. An annular member 39 is secured to the lower end, is engaged by an annular element 46 which is operated to raise or lower the rod 27 according to the dictates of a cam 43. In its lowered position the upper end of the rod rests in a recess 48 in the sinker ring so that the fabric which is drawn from the needles by the take-down mechanism 53, in which it passes through the member 39 and element 46, passes over the tip 54 of the rod, Fig. 6. When the rod is raised by element 46 the tip 54 engages the sinker loops of the two succeeding courses containing the separating course, Fig. 7, whereafter the rod is lowered to avoid engagement of further courses. As knitting proceeds the two sinker loops pass down the rod, Fig. 8, and subsequently engage a cutter 64 which severs them.
