Abstract: 1,151,955. Dishwashing machines. G. S. BLAKESLEE & CO. 18 Aug., 1967 [23 Aug., 1966], No. 38236/67. Heading A4F. [Also in Divisions B2 and B8] A dishwashing machine comprises a housing 2, Fig. 8, having a track for supporting articles to be washed, e.g. consisting of rails 34 supporting rollers 177 of an endless chain conveyer, and a pump 103 for directing washing liquid from a sump 104 through a riser 74 extending up one side of the housing to an upper and a lower spray box 56, 46 for directing washing liquid on to the articles from above and below. The spray boxes 46, 56 are rectangular in plan view and have projecting therefrom three rows of plastics spray nozzles 53 having discharges slots disposed lengthwise of the box 46 or 56 in the outer rows, and slightly inclined to the lengthwise direction in the middle row. Perforated scrap retaining strainer trays 44 (Fig. 9, not shown) are disposed at the sides of the lower spray box 46; and both spray boxes 46, 56 are removably mounted in the machine. The door 15 of the machine housing is opened by sliding it upwardly, and be held in a partly open position by a latch 97 to enable the trays 44 to be removed and cleaned. The conveyer may comprise side chains 175, Fig. 20, connected by cross rods 176 coupled by U-shaped links 179, 180 shaped to receive the edges of the plates to be carried by the conveyer. Other articles to be washed may be carried in openwork baskets placed on the substantially flat upper run of the conveyer. If a plate is not removed at outlet end of the conveyer it actuates trip fingers 147, Fig. 21, to turn cams 129 for actuating, via trip arms 130 and rods 136, switches 143 to stop the conveyer motor. Alternatively if a dish basket is not removed from the conveyer it will actuate a trip yoke 165 to depress the rods 136 to stop the conveyer motor. In another embodiment a dish basket 230, Fig. 12, is passed on rails 34a through the washing chamber by a conveyer comprising pawls 227 pivotally mounted on a bar 197 reciprocated by link mechanism 211, 215, 217, 222 driven by an electric motor 209 via reduction gearing 210. The bar 197 is suspended at its ends in pivoted cradles 187, and it may readily be turned so that it may drive the dish basket in the opposite direction if desired. In an opening in one of the rails 34a is mounted an actuator 234 (Fig. 23, not shown) responsive to the movement of a dishbasket thereover to close a switch to open a solenoid valve to admit rinsing liquid to sprayers disposed at the delivery end of the washing chamber.

Title: Production of polyoxyalkylene compounds
Inventor: HOLLAND STEPHEN DONALD
IPC: C08G65/28
Filed: 1957-12-11
Abstract: Polyoxyalkylene compounds of high molecular weight are obtained from similar compounds of lower molecular weight by adding to the latter a solution of an alkali metal, or an oxide, hydroxide, carbonate or alkoxide thereof in the lower molecular weight compound or in one having substantially the same molecular weight and reacting the resultant solution with an alkaline oxide. The process may be repeated until a product of the required molecular weight is obtained.  The solution of the alkali &c. in the lower m.w. compounds may be obtained by dissolving them in a mutual solvent and then evaporating off the solvent.  The lower m.w. compound has a m.w. of about 300 and the product obtained a m.w. of at least 9000.  Alkylene oxides specified are ethylene, propylene, butadiene, butene, amylene, cyclohexene, styrene. The lower m.w. compound may be a simple polyglycol obtained from an alkylene oxide and a glycol or one having ether, thioether, ester, amine groups at the end of the chain. Mutual solvent for the polyglycol and the catalyst may be methanol. In an example polyethylene glycol of m.w. 300 was mixed with a solution of sodium methoxide in the same glycol obtained by adding liquefied methanol to the mix and then stripping off the methanol at 60 DEG  C. under vacuum.  Ethylene oxide was passed into the reactor at 125 DEG  C. and the viscosity of the solution tested periodically until it reached 23 centistokes; the product had then a m.w. of 1500. With further reaction with fresh catalyst and ethylene glycol products of m.w. 4000 and 9000 were obtained.

Abstract: 1332423 Tobacco-smoke filter manufacture F J BURRUS & CIE 19 Aug 1971 [12 Oct 1970] 38908/71 Heading A2C  In an apparatus for making tobacco-smoke filters in which a free running filter material is fed into spaces 17 between uniformly spaced, axially aligned, fibrous filter wads 1, 2 travelling on a continuous wrapper strip 3, suction is applied by a device 21, situated upstream of the discharge slot(s) 20 of a filler head 16 and above the wads 1, 2, so as to produce a partial vacuum within the spaces 17 to be filled to aid the complete filling thereof. The wads 1, 2 are deposited in known manner on the wrapper strip 3, previously provided with a thermoplastic adhesive coating on its upper surface, and fixed thereto by heat. The edges of the strip 3 are then bent upwards around the wads 1, 2 to form a U-shape before passing under the suction device 21. After the filling of the spaces 17, surplus filter material is removed by a trimmer 30 and the edges of the strip 3 are brought together and overlapped by a member 43, a suction device 45 removing any free-running filter material remaining between the edges of the strip 3, and said edges are then heat sealed together. A further heat sealer (62) Fig. 8 (not shown) ensures that the strip 3 is stuck to the filter wads 1, 2 around the whole of their circumferences. Finally, the continuous composite filter rod so formed is cut into suitable lengths, the cutter (51) Fig. 1 (not shown) being driven by the main machine via a phase adjustable timing mechanism (52) Fig. 9 (not shown) so as to synchronise it with the feed of the wads 1, 2. A vibrator 23 is provided to facilitate the flow of the free-running material within the filler head 16.

Title: Improvements in and relating to resilient materials
Inventor: EVERETT LILIAN FRANCES
IPC: B29C44/04
Filed: 1962-10-18
Abstract: A resilient material consists of a set rubber (natural or synthetic) latex foam and a set polyurethane foam, in which each foam constituent has its own individual lattice structure and the two structures are intermingled and coextensive so that they jointly form a mass occupying a space in common.  In a preferred embodiment it is made from rubber latex foam formed and set on separately preformed and set polyurethane foam so that the rubber latex foam is reinforced throughout its structure by the polyurethane foam.  The rubber latex fluid which may contain a gassing agent e.g. H2O2 or may be in the form of a dense fluid foam, may be introduced into the set polyurethane foam by compressing the latter and then allowing it to take up the rubber latex fluid like a sponge. Alternatively the polyurethane foam may be impregnated by placing a pad of it on top of a pool of rubber latex fluid contained in a mould and reducing the pressure. The polyurethane foam thus soaked with the rubber latex fluid is subject to treatment to cause the rubber latex to form or expand its existing foamed state. The rubber latex foam is then gelled, e.g. by freezing and injection of CO2, and vulcanized.ALSO:A resilient material consists of a set rubber (natural or synthetic) latex foam and a set polyurethane foam, in which each foam constituent has its own individual lattice structure and the two structures are intermingled and coextensive so that they jointly form a mass occupying a space in common.

Title: Improvements in and relating to Surge Protection Circuits for Electrical Generators
IPC: B22C21/02
Filed: 1967-08-30
Abstract: 1,184,079. Protective arrangements. ROBERT BOSCH G.m.b.H. 30 Aug., 1967 [31 Aug., 1966], No. 39658/67. Heading H2K. [Also in Division G3] An A.C. generator under the control of a transistorized voltage regulator is provided with a circuit which protects the regulator against excessive voltages which can arise, for example, when a load is suddenly removed from the generator, the protection circuit including a controllable semi-conductor rectifier which is rendered conductive, on the occurrence of such an over-voltage, to short-circuit the regulator. As shown, the rectified output of an alternator 10 having a field winding 17 is controlled in known manner by a transistorized regulator 24 connected across the output leads 16, 19 of the alternator and the regulator is shunted by a protective circuit 27 which includes a thyristor 28 having its control electrode connected over a Zener diode 29 to a voltage divider 44, 45, 46 responsive to the voltage across leads 16 and 19. The arrangement is. such that Zener diode 29 conducts if the output voltage rises to an excessive value, thereby firing thyristor 28 which short-circuits the regulator 24 and the leads 16, 19 so that the alternator output voltage drops to its short-circuit value, e.g. 1 volt; at the same time, the alternator is de-excited, and the semi-conductor elements in the regulator and in the alternator's rectifier circuit are thus protected against the over-voltage. The protection circuit may be simplified by omitting the Zener diode 29 (Fig. 3, not shown), or it may include an amplifying transistor and a temperaturecompensating thermistor (Fig. 2, not shown). The protective arrangement may also be applied to an alternator having a permanent-magnet field (Fig. 4, not shown).
