Title: Filter presses
IPC: B01D25/127
Filed: 1962-10-12
Abstract: 986,402. Filter-presses. O. EMELE. Oct. 12, 1962 [Oct. 12, 1961; June 13, 1962], No. 387723/62. Heading B1D. A filter press comprises a plurality of filter plates and a sheet of filter material constituting a plate wall covering on each side of each filter plate, each plate wall covering being connected to the adjacent covering between adjacent filter plates and being connected to the filter plate which it covers and to the wall covering on the other side of the filter plate which it covers, whereby when two adjacent filter plates are drawn apart the adjacent wall coverings between said plates define a chamber which is open at the bottom and has sides at an acute angle to each other. In Fig. 1 the filter material 10 is held in slots 27 of bars 28 suspended by springs 29 from a rod 24, and connected to the plates 5 at the filling channels 31. In Fig. 3, the filter materials 10 are connected by strips 32 to the plates 5, the obtuse angle of the filter material forming on opening the chamber facilitating detachment of the cake 12. In Fig. 4, the same effect is achieved by connecting the two filter materials 10 of one chamber together by strips 33 in the upper half of the press. In Fig. 5 the plates 5 are connected to the supporting bar 28A by connecting members 34 at the top of the plates, so that bar 28A is exactly mid-way between the plates when the chamber is open, and the spring-actuated bar 28A is moved downwards so that the filter material 10, relieved of tension, assumes an arched form as shown, assisting cake detachment. Strips 32, 33, 34 are flexible and may have some elasticity. In Fig. 6 the springs 29 are replaced by weighting rods or tubes 37 in the bottom fold of the filter material which is thereby kept taut and the strips 38 connecting the filter materials effect the movement thereof into a tilted position on opening the chamber.

Title: Improved glass distillation flask
IPC: C03C17/02
Filed: 1956-12-20
Abstract: 827,395. Glass manufacture. ESSO RESEARCH & ENGINEERING CO. Dec. 20, 1956 [Dec. 27, 1955], No. 38864/56. Class 56. A glass container comprises a walled vessel having an inner wall surface and a coating on at least a portion of the inner surface consisting of a first layer of finely divided glass particles substantially of single particle thickness at least partially fused to the surface and to each other and a second layer also of single particle thickness bonded by fusion to particles of the first layer and to each other to give a uniform series of closely spaced protrusions and crevices and interconnecting pores between the particles. The flask 1 is held by a chuck2 at one end of a shaft 3 mounted on a standard 4 and rotated as by belt 6 and pulley 5. Finely divided glass particles 8 more than half fill the flask which is closed by a glass wool packing 7. The lower part of the flask 1, in which the lining is required, is surrounded by a combustion unit 10 having burner ports 11 supplied through ducts 12 with combustion fuel. The remainder of the flask 1 is covered with an insulating layer 9 of asbestos, made from a paste of wet fibres allowed to dry thereon. The flask is rotated and the glass particles remain in intimate contact with the heated portion of the flask so that a layer of the particles is fused to the inner surface thererof. Heating is continued until a second layer adheres to the first, when the excess particles are removed and the flask then reheated to fuse the second to the first layer. The temperature induced is such as to lie between the annealing and the softening temperature of the glass. For example, for a borosilicate glass of melting point 820‹C. and annealing temperature of 560‹-600‹C., a preferred heating range is 600‹-750‹C The glass particles are preferably of the same composition as the flask. The coating has a frosted appearance and has closely spaced protrusions and depressions which increase the area of the flask in contact with a liquid, preventing large bubble formation during distillation of the liquid and assisting in the observation of distillation dry point.

Filed: 1962-10-16
Abstract: 953,827. Shelling almonds. C. MARTELLI. Oct. 16, 1962, No. 39039/62. Heading A4C. [Also in Division B5] Apparatus for cutting almond shells includes a storage hopper 3 from which nuts are fed singly and orientated to be received in a predetermined position in a clamp 15, means for advancing a cutting device 39, 40 into contact with the clamped nut and means for rotating the clamp 15 together with the nut relative to the cutting device 39, 40 thereby to cut into the shell over its periphery. The sequence of operations is controlled by linkages driven by cams mounted on a common drive shaft 2 supported by side plates 1 of the machine. Clamps 15 extend through apertures 8a, 8b in transversely slidable elements 5a, 5b having channels 7a, 7b which accommodate a single nut which, when the elements 5a, 5b are closed, is received from the hopper 3 through an appropriately cross-sectioned channel 4 and an aperture 6a in a shutter blade 6 carried by one element 5a. The opening and closing of elements 5a, 5b is effected by pins 14b on a collar 14 carried by the shaft 2, which pins 14b engage pivoted levers 10 biased by a spring 12 and operatively connected to the slidable elements 5a, 5b. Stems 16 carry the clamps 15 which are opened against the action of springs 18 by a pivoted lever linkage 19-24 when a pin 25 on the shaft 2 engages the lever 24, the levers 19, 22 engaging stops on the stems 16. Partial or complete rotation of the clamps 15 is effected by cog wheels 26 which drive the stems 16 through pins 27 engaged in forks 28 on the stems 16. The cog wheels 26 are driven intermittently through chains 30 and cog wheels 31, the latter being mounted between a boss 34 secured to the shaft 2 and a cam 33 mounted on the side plate 1 and the arrangement being such that the cog wheels 31 are rotated when spring biased pins 35 carried thereby are urged into engagement with an extension 34a on the boss 34 by an upstanding surface on the cam 33. Circular saws 39, 40, supported by units 41, 42 in turn supported in slots 43 in the side plates 1, are biased by spring 46 towards the clamped nut and are flanked by adjustable sector-shaped plates 48 with the cutting edge projecting beyond the plates 48, which engage the nut, in accordance with the depth of cut required. The saws 39, 40 are driven at high speed through couplings 39a, 40a. The saws 39, 40 are moved simultaneously outwards from the clamping zone in timed sequence by means of links 51, 56 and a rocker 54, the rod 51 bearing at one end on a disc 52 having a slot 52a engaged by the shaft 2 and the disc 52 cooperating with a cam 53 mounted on the shaft 2 whereby the saws are separated against the action of the springs 46 when the cam 53 operatively engages the disc 52.

[Also in Division F1] A vacuum pump is driven by a brushless motor having a permanent magnet rotor cooperating with stator windings which are energized from a D.C. supply through transistors controlled by Hall devices influenced by a magnetic field varying in the same way as the stator field. The vacuum pump (see Division F1) has an axially extending rotor (1) and is provided at one end with a motor having the permanent magnet rotor (18) enclosed in a can and an external, wound, laminated stator (18, 19), Fig. 1 (not shown), and at the other end a similar machine acting as a control generator shown in Fig. 3. The control generator has a permanent magnet rotor 22 enclosed in a can 23 and co-operating with a stator having windings 42-45 and surrounded by an octagonal ring 25 on which are mounted main transistors 50-53 and auxiliary transistors 46-49. The auxiliary transistors are controlled by the Hall plates 35, 36 which are mounted between the segments of the stator core of the control generator and the additional voltage generated in windings 42-45 as the speed increases. In operation when no signal is present across the Hall plates equal currents flow in the main windings 27-30 but these are varied when voltages appear at terminals 58, 59; 60, 61 on the Hall plates. As the speed of rotation increases the voltage induced in windings 42-45 aids the voltage appearing across the Hall plates.

Abstract: 1,196,268. A/D converters. KNORRBREMSE G.m.b.H. 29 Aug., 1967 [31 Aug., 1966], No. 39552/67. Heading G4H. [Also in Division F2] A control arrangement for electropneumatic rail vehicle brakes of the type in which any one of at least three lines is connected to a supply source, each connection combination providing a particular braking condition, comprises a potentiometer 5 to the tap of which are connected a number of circuits equal to the number of control lines. Each circuit comprises a relay A, B or C and a number of Zener diodes some of which, 9, 11, are bridged by normally closed contacts on the relays. Assuming that tapping on the potentiometer 5 starts from zero, and is gradually increased, then initially all relays are de-energized. Increasing the tap potential to the Zener point of diode 12 (2 volts) causes relay C to operate and connect line 15 to supply 17. A further increase in potential to the Zener point of diode 10 (5 volts) causes relay B to operate. Contact b<SP>1</SP> then opens to switch diode 11 in series with diode 12 so that relay C releases. Line 14 is then connected to the supply. A further increase in tap potential to above 9 volts (Zener potential of diodes 11, 12 in series) causes relay C to re-energize so that lines 14, 15 are both connected. Further increases in tap potential result in the energization of relay A alone, relay A and relay C, relay A and relay B, and finally all three relays. The outputs on lines 13, 14, 15 may therefore have eight different combinations representing "off" and seven degrees of braking depending on the setting of potentiometer 5.
