Title: Improvements relating to ice bank apparatus
IPC: F25D31/00
Filed: 1960-10-24
Abstract: 916,484. Cooling liquids. DENISOFF, A. C. Sept. 27, 1961 [Oct. 24, 1960], No. 36409/60. Class 29. [Also in Groups XVII and XXIX] In ice-bank apparatus comprising a tank and an evaporator for forming an ice-bank therein, a horizontal open-topped channel leads water from an inlet region of the tank over the evaporator to an outlet aperture in the tank bottom wall, and a duct beneath the bottom wall leads in a generally horizontal direction from the outlet to water circulating means, the width of the duct being greater than its height. The apparatus shown is generally similar to that described in Specification 829,484. The tank 2 comprises insulating material 14, e.g. expanded plastics or granulated cork, sandwiched between an inner shell of resin-bonded fibreglass and an outer shell of steel and has a central outlet 25 from which chilled water flows via the wide duct 26, formed within the thickness of the insulation, to a sump 27 formed integrally with the tank. A pump 9 supplies water from the sump to sprays 8 for cooling milk in an inner pan 4 and the water is returned to the outlet via a spiral channel 15 which supports water-cooling evaporator coils 17. In a modification (Fig. 4, not shown), the tank contains two spiral walls each leading to a central outlet opening and a common duct. In another alternative, the duct extends the whole width of the tank.

[Also in Divisions D1 and F2] The reversing washing drum of an automatic washing machine is controlled by electric contacts operated by discs NI 1 , NI 2 , 13 and 14 driven continuously with a cam 20 by a synchronous motor 1 through gearing 2-9 which also continuously reciprocates through an eccentric 27 a pawl 25 normally biased by a spring-loaded arm-peg 39, against a spring 31, into engagement with the recessed cam 20, so that when the pawl drops into the recess it engages and drives an adjacent coaxial ratchetwheel 24 fast with other washing machine electric control contact discs NP 1 - 4 . The peg 39 engages an edge 39a of the pawl 25 and may be released therefrom by attraction of its carrying arm 34 by an electromagnet 43, controlled by one of the discs NP 1 - 4 , so that the pawl 25 is disengaged completely by spring 31 from the ratchet-wheel 24 or cam 20. The position of the discs NP 1 -NP 4  may be manually adjusted by a knob 12a against a spring-pawl and ratchet-wheel 15-13a which also prevents back-running of the ratchetwheel 24 fast on the shaft 11 carrying discs NP 1 -NP 4  and ratchet-wheel 13a.

Abstract: 396,282. Lubricating. SCHMITT, W., 5, Bismarckstrasse, Ettlingen, Baden, Germany. Dec. 29, 1932, No. 36807. Convention date, Sept..5. [Classes 12 (ii) and 12 (iii).] The moving parts of a horizontally movable slide 5 of gear-cutting machines are lubricated by means of a pump or other feeding device 3 feeding oil automatically from a reservoir 2 in the machine through rigid or flexible pipes 4, 6 to the upper part of the slide, whence suitable passages or channels convey it to the parts to be lubricated, oil returning to the reservoir by a pipe 14. The pipe 6, which is movable, delivers into a trough 7. Channels lead oil from the trough 7 over the upper spindle guide 9 and dividing worm-wheel 10 to a receptacle 11, whence further channels conduct the oil through a hole in a bushing 16 on to the cutter spindle 8. Air escapes from between the teeth of the segment 12 and the spindle 8 through a diametrically opposite hole in the bushing 16. Oil collects in the bottom of the slide, into which the return pipe 14 opens. The pipe 6 may lead to the receptacle 11. This system is particularly adapted to provide adequate lubrication when sliding takes place between the teeth of the segment 12 and the cutter spindle upon an additional rotary movement being imparted to the spindle 8 during the cutting of worm wheels.

Abstract: A method of master-batching pigments for further use in synthetic resins comprises mixing from 40-75 parts of pigment with 60 to 25 parts of synthetic rubber.  The synthetic rubber may be a polymer of 100-60 parts by weight of butadiene and 0-40 parts by weight of styrene.  The pigment may be carbon black, metal powder, titanium dioxide, iron oxyhydrates, ultramarine blue, other oxidic and sulphidic inorganic pigments, azo pigments, vat dyestuffs, phthalocyanine, bisoxacine, perylene tetracarboxylic acid and quinacridone duestuffs.  The pigments are incorporated in the polymer in a kneading or roller churn at a temperature between 50 DEG  and 80 DEG C. and then rekneaded at a temperature between 70 DEG  and 90 DEG or even higher until a homogenous mixture is obtained.  Up to 35% (calculated on the weight of the polymer) of a fatty acid or salt of a fatty acid containing 12 to 20 carbon atoms, such as stearic acid or aluminium tristearate, may be added to improve dispersion.  The mixture is then comminuted or granulated and added to a polymer such as natural or synthetic rubbers, polyvinyl chloride, polyvinyl acetate, polyethylene, polypropylene or polystyrene in the quantity desired.

Abstract: 1371835 Variable capacitor displacement transducers GEORGE SALTER & CO Ltd 7 Aug 1973 [10 Aug 1972] 37312/72 Heading G1N [Also in Division H1] A displacement transducer includes a variable capacitor formed of a fixed electrode 15, Fig. 1, and a slidable electrode 12 which can move within an insulating guide tube 14 so as to overlap a tapered portion 16 of the fixed electrode. The slidable electrode is connected to a probe 11 so that the displacement to be measured by the probe varies the overlap of the electrodes and hence varies their capacitance. An oscillator circuit 39 changes its frequency as the capacitance varies, and the taper of electrode portion 16 is chosen to give a linear relationship between frequency and displacement. A set of metal loops 46, Fig. 3, is provided which are mounted on the outer casing of the transducer and which are electrically connected thereby to the fixed electrode. By use of adjusting screws 50 the relationship between capacitance and displacement can be finely adjusted. An alternative fine adjustment may be provided by a layer of conductive paint (not shown) on the outside of the guide tube, this paint being selectively removed to give the required adjustment. The output frequency may be digitally displayed.
