Title: Process for the production of porous bodies from polyethylene
IPC: C08J9/24
Filed: 1955-07-20
Abstract: A porous polyethylene article is made by compressing particulate polythene into a shape-retaining body, and then heating the body at a temperature between 100 DEG C. and the temperature (approximately 400 DEG C.) at which decomposition and/or gelation will occur.  The particulate polythene may be in the form of powder, granules or fibre.  The lower limit of pressure is about 3kg./sq. cm.  Highly porous articles are obtained by low compression and low temperatures, e.g. 150 DEG  or 175 DEG C., and a low degree of porosity by high pressure and temperatures of e.g. 250 DEG -300 DEG C.  During heating the articles may be compressed.  The production of a cylinder and a sheet is described.

Title: Improvements in centrifugal extractors
IPC: B04B7/06
Filed: 1924-09-06
Abstract: 235,054. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Sept. 6, 1924. Casings; driving.-The controller for the driving means of a centrifugal extractor normally tends to move to the " off " position, and is held in the " on " position by releasable means which are interlocked with the cover and rendered ineffective when the cover is open. The holding means are released automatically after a predetermined time. The basket 3 is driven bv the belt 6 from the electric motor 7 which also drives the timing mechanism through the coupling 8 and the flexible shaft 9. The spindle 17, Fig. 6, in the casing 10 is driven through worm gearing and is connected to the dial 19 by a clutch 18 controlled by the spring button 20. A finger 22 extends through the casing 10 and is held by a spring 22a in engagement with a notch in the vertical rod 25, the lower end of which is linked to an arm 31 secured to the rock shaft 32. The ball 35, Fig. 9, hangs from an arm 33 on this shaft and engages a socket member 36 on the brake treadle 37. The arm 31 engages the switch closing member 44 and the arm is raised by depression of the treadle 46. Thus, depression of the treadle closes the motor switch and raises the rod 25 until the finger 22 enters the notch in the rod 25, which is thereby held in its raised position. With the dial 19 of the timing mechanism set, the machine will run until the finger 22 is withdrawn from the notch by the tripping of the projection 27 by the lug 21 on the dial 19; the rod 25 then drops and opens the motor switch and applies the brake 39. The sliding block 50, Fig. 4, on the motor shaft is controlled in its movement by the centrifugal mechanism 51, so that it is lowered when the machine runs. The block is connected by links and rods to the arm 63, which operates a latching member 64 to move the cut-out portion 66 away from the lug 68 on the cover, which cannot then be opened. A. cam on the cover is arranged to prevent the finger 22 from engaging the rod 25 when the cover is open, so that the timing mechanism cannot be set and the switch cannot be latched in its closed position.

Filed: 1971-04-19
Abstract: 1338435 Electroless plating PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [10 Feb 1970] 21145/71 Heading C7F [Also in Divisions G2 and H1] Electrically conductive metal images or layers are produced by (i) coating on electrically insulating support with an electrically insulating layer comprising a binder consisting of thermosetting resin(s) and synthetic and/or modified rubber(s) in a weight ratio of between 4:1 and 1:4 in which is dispersed a finely divided light-sensitive metal oxide, the weight ratio of binder to metal oxide being between 8:1 and 1:4 and the layer being between 5 and 20 microns thick, (ii) heating the layer to between 130 and 200C for 2 to 15 minutes to increase adhesion of the layer for the support and then image-wise or uniformly treating with a chemical bath to remove the top 0À1 to 1 micron of the layer to expose the metal oxide (iii) imagewise or uniformly exposing the layer before and/or after treating the layer with a solution of a salt of Cu, Ag, Hg, Au, Pd or Pt to produce a metal nuclei image or layer and, if necessary, removing any remaining metal salt (iv) and intensifying the nuclei image or layer with a stabilized physical developer or an electroless Cu, Ni and/or Co plating bath to form a conductive metal image or layer which may be reinforced by electrodeposition. In the examples, a heat- and chemically-treated metal oxide layer is dipped in a solution of PdCl 2 , uniformly or image-wised exposed to produce a layer or image of Pd nuclei, the remaining PdCl 2  being washed off when an image is formed and the nuclei are intensified with either a copper plating solution containing copper sulphate, tetra sodium salt of ethylene diamine tetra acetic acid, caustic soda, formaldehyde and polyethylene oxide or a nickel plating solution containing NiCl 2 , sodium, hypophosphite and glycollic acid. The copper image or layer may be further thickened up to 30 microns by electro-deposition using copper sulphate and sulphuric acid. When copper layers are thickened they are first covered with a pattern of acid resist and after electro-deposition, the thin copper layer under the resist is removed by etching. The nuclei image may be produced alternatively by using photo-resists (see Division G2). When used for printed circuits, the support is prepared so that it contains the light, sensitive oxide and when holes are bored, they can be treated with PdCl 2 , exposed and plated as above. Alternatively the support contains an ion-exchange compound or resin and is charged with a solution of sodium dithionite, sodium borohydride, sodium hypophosphite stannous chloride or other reducing agent, holes are bored, PdCl 2  solution applied and the support exposed and plated as above. If light-sensitive layers are provided on both sides of the supports treatment of the bored holes with a solution of PdCl 2  and SnCl 2  is sufficient for plating the holes.

Abstract: 778,623. Monitoring equipment. WHITE, G. Aug. 4, 1953 [Aug. 2, 1952], No. 21469/53. Class 40 (4). Monitoring equipment for selectively connecting a monitoring device to one or more lines includes a two-wire coupling circuit, over which such connection is effected, in which each leg of the two-wire connection includes a chargestoring capacitor in parallel with charge-retarding impedance and a switch for short-circuiting the capacitor-impedance network so formed. As shown, four telephone lines may be connected to terminals 31<SP>1</SP> to 34<SP>1</SP>, respectively, and neon lamps 35 to 38 will flash if ringing current is applied to the lines. The operator's telephone (or other monitoring device) is wired to terminals 85. To monitor one of the lines, say that connected to terminals 31<SP>1</SP>, the operator rotates switch 80 to bring the wipers 81 on to terminals 76, and operates switch 75 to the position in which terminals 31<SP>1</SP> and 76 are interconnected, having ensured that contacts 82 are open. The capacitor-impedance networks 83, 84 suppress the click when connection to the line is made. Operation of switch 75 to connect terminals 31<SP>1</SP> to resistance-capacity shunt 59, 63 introduces a loss into the line being monitored to cause one or other of the parties to repeat part of the conversation, whereas operation to connect 31<SP>1</SP> to the impedance 71 serves to hold the call being monitored. An impulse counter for recording dialled digits and a polarity reversing switch, both of which may be used with the arrangement of Fig. 2, are also described.
