Abstract: 1,162,779. Hydraulic jacking arrangements. MITSUI SHIPBUILDING & ENG. CO. Ltd. 9 Aug., 1968 [12 Aug., 1967], No. 38073/68. Heading B8J. [Also in Division E2] A jacking apparatus for raising a platform B comprises a cylindrical support P, for a heavy weight such as a ship or derrick attached to the platform B, secured to the sea bottom. Upper and lower rings 1, 2 surround the support P and each has a taper ring 3, 4 comprising three arcuate members with intermediate compression springs (11), Fig. 2 (not shown). Rubber or like rings 5 are on the inner surfaces of the rings 3, 4 while the platform B is suspended from the upper ring 1 by rods 6. From the starting position in Fig. 1 the platform B is lifted step-by-step along the support P as indicated in Figs. 3a to 3d. Fig' 3a shows three main hydraulic jacks 7 between the rings 1, 2 extended thus lifting the ring 1 and attached platform B along the support P, the weight being taken by the clamped ring 2. Lifting of the ring 1 releases the taper ring 3 which is expanded by its compression springs (11) so that it can be lifted, Fig. 3b, and forced into the gap between the ring 1 and the support P by three hydraulic jacks 9. Three hydraulic jacks 8 then lift the ring 2, Fig. 3c, and the starting position is recovered by lifting the taper ring 4 by three hydraulic jacks 10. The lowering operation is illustrated in Figs. 4a to 4# (not shown). Instead of pressure oil to operate the jacks water or air under pressure may be used. The support P may be lifted or lowered with respect to a fixed platform if required.

Title: Improvements in apparatus for drying filter cake
IPC: F26B17/02
Filed: 1929-12-18
Abstract: 345,247. Drying filter-cake. JOHNSON, G. W., 47, Lincoln's Inn Fields, London. -(Proctor & Schwartz Inc.; 7th Street, Philadelphia, U.S.A.) Dec. 18, 1929, No. 38849. [Class 34 (ii).] Filter cake is dried on an endless conveyer belt passing from a filter drum through a drier, means independent of the drum-driving means being provided for advancing the conveyer within the drier as well as means for automatically controlling the speed of the drum through the medium of the belt. A foraminous belt 6, Fig. 3, from a filter drum 2 traverses a drier 7 in the form of loops borne on gists 12 of an endless carrier 13, and is drawn out of the loop form by a rear drum 25. A loop is formed in the belt between the drum and the drier, which by bearing on a series of curved fingers of a lever 55 actuates a rheostat 52 to control the speed of the drum 2 and the rate of feeding the belt into the drier. A self-adjusting looping roll 14 fitted with a scraper 20 and attached to a swingletree controls the looping of the belt as it passes from a drum 10 also fitted with a scraper 19 and contacting with a punch roll 21. The belt as it passes over a guide-roll 8 is prevented from moving laterally by a differential device which always brings the belt back to its normal position. At the discharge end of the apparatus a rotary beater 26 dislodges the dried material from the conveyer discharging it through a hopper 29 into a trough 31 having a screw conveyer 32 removing the material from the apparatus. Any loose material in the hopper 29 is collected in a pivoted trough 44 having a screw conveyer 47 to take the material to a shoot which discharges it into the lower trough 31. The trough 44 also prevents the slipping of the belt when the last loop is drawn out and on being raised about its pivot actuates a switch 64 controlling a motor 60 driving the rear drum. In this manner differential movement of the belt resulting from the removal of the dried material from it by the beater 26 is controlled. Driving means for the apparatus comprises three motors operated through switches 57, 61 .. 64 actuated by the belt in certain positions to ensure even running of the belt throughout the apparatus. Switch 61 is operated by lever 55 while switches 62, 63 are in the path of the weight 35 of a tension roll 34. Switches 61, 62, 63 are each capable of stopping the three driving motors 3, 59, 60, Fig. 2. The drier 7 comprises a central chamber a, Fig. 4, and side air-circulating compartments b with heating means and fans c.

IPC: G01R1/02
Filed: 1930-12-24
Abstract: 357,450. Indicating-apparatus. CAMBRIDGE INSTRUMENT CO.; Ltd., MASON, C. C., and STALLAN, W. J., Chesterton Road, Cambridge. Dec. 24, 1930, No. 38908. [Class 106 (iv).] In a measuring instrument the scale of readings is modified by means associated with the pointer and adapted to vary its pivotal point to alter suddenly the ratio of movement of the pointer with respect to that of the moving mechanism. As shown a pointer 1 is pivoted at 2 to a spring-controlled link 3 itself pivoted on a fixed pivot 4. The operating mechanism, e.g. a Bourdon tube, is attached to the point 9 of the pointer and stops 10, 11 are provided to obstruct the free movement of the pointer beyond the points 7, 12 of the scale 8. Movement of the point 9 to the left of the position shown in full lines will cause the pointer to rotate about the stop 10 as a pivot thus reducing abruptly the magnification of the movement. Similarly movement to the right beyond the dotted line position reduces the magnification beyond the point 12 of the scale. The stops 10, 11 may be placed in any desired relative positions with respect to each other and to the pivot 2.

[Also in Group XIX] An automatic sales recorder (see Group XIX) is located at the check-out gate of a self-service retail store. The price of each item and other information, is represented by punched holes or opaque overprints on an adhesive-backed fluorescent-coated label 11. The customer places merchandise on a belt-type conveyer 18, label upwards, and a store employee at the wrapping station 14, by foot pedal or similar control, operates the conveyer to carry the merchandise at suitable speed through the scanning station 22. Areas 24 of upright resilient rubber or plastic cones serve to hold round objects and prevent them from rolling. A switch (not shown) or wooden separators 26 covered by coded labels, are placed on the belt to indicate to the scanning equipment the separation of customers' lots. At the scanning station a television camera system detects, and adjusts itself to read, each label, and enters the data into a computer which issues a sales slip 28 and may issue stamps also. The account is settled at the cashier's station 16. Provision is made for entering items by keyboard when unlabelled goods appear.

The latter member is biased against a seat of the body 5 by a spring 4 which also co-operates with the support 3 to maintain the main member 1 seated in the auxiliary member 2. A pressure delay chamber including partitions 10, 10<SP>1</SP> possessing passages 16, 17 is provided beneath the valve, the stem of the main valve member 1 being extended to carry a piston plate 11 reciprocable in the cylinder. The plate may be connected to the wall of the cylinder by a flexible diaphragm. In a modification the piston plate co-operates with that part of the pressure delay chamber adjacent the valve assembly (Fig. 3, not shown).

Filed: 1960-11-17
Abstract: A method of packaging carboys (see Group XVII) includes moulding round them a foamed plastics envelope, the cells of the envelope being discrete and non-communicating.  In one moulding method, small particles of porous pre-expanded polystyrene are introduced into the space between the carboy and a surrounding mould, the particles containing an expanding agent such as petroleum ether.  Heat is applied by steam at temperature of from 230 DEG F.-275 DEG F. to cause final expansion to fill the mould. Cooling to 70 DEG -80 DEG F. precedes withdrawal from the mould.  In another method, a liquid mixture comprising organic polyisocyanate and water and a material of the polyesters and polyethers group is poured into the mould and allowed to foam and cure.  A formulation for preparing foamed polyurethane, for example, comprises a polyester made from adipic acid and trimethylol propane, a fire retardant, emulsifying agent and the catalysts N-methylmorpholine and tetrahydroxethylethylenediamine. Other examples of materials for both methods are given.  In preparing the pre-expanded particles used in the first method, polystyrene beads containing petroleum ether may be heated at a temperature of 220 DEG -250 DEG F. for about 1-2 minutes.ALSO:A method of packaging carboys (see Group XVII) includes moulding round them a foamed plastics envelope, the cells of the envelope being discrete and non-communicating.
