Title: Improvements in foot exercising and arch correcting devices
IPC: A61H15/00
Filed: 1936-01-29
Abstract: 469,666. Foot - massage appliances. BOLTZ, F. S., and ESTEY, G. W. Jan. 29, 1936, No. 2729. [Class 81 (ii)] Apparatus for foot-exercising and massage comprises a foot holder, a roller, and means for causing the roller to travel over the underneath central portion of the foot, the surface of the roller being so constructed that it will apply an intensified pressure to certain parts of the foot when the roller is forced along the underneath of the foot, the roller being counterweighted so that when removed from and reapplied to the foot, its surface will always contact with the foot at a specified point of the roller. The device shown consists of a box 12 having an inclined hinged cover 14 formed with an opening 15 which is covered by plate 32 having openings 32a which in use are bridged by the arches of the feet. The openings 32a are covered with cloth 8 clamped between the plate 32 and cover 14 and plate 7, Fig. 3. Heel plates 30 are connected by a bar which may be clamped in different positions on plate 32. Toe-caps 38 of flexible material are clamped to a rim base 45, and are connected by a bar which also may be clamped in different positions on plate 32. Massage rollers 20, 21 are freely mounted on rods 21a rigidly secured to arms 22, 23 carried by shaft 24 which is rotated either by motor 9 through reduction gearing 24a, or by hand. The rollers may be cylindrical, but are preferably in the form of truncated cones and are provided with protuberances positioned to engage with the arches of the foot. In the development of one of the rollers shown in Fig. 4, the protuberances 25, 26, 27 and 28 operate on the posterior, anterior, inner and outer arches respectively. Each roller is provided with a counterweight 29, so that after each roller has been rolled along the foot, it always returns to the position in which the protuberance 25 will contact with the posterior arch. The cloth 8, which is positioned between the rollers and the feet, is sufficiently full to allow it to be flexed by the upward pressure of the rollers. The degree of pressure by the rollers on the feet is varied by adjustment of the inclination of the cover 14 through adjusting screw 48 passing through fixed bracket 49. A weight 50 is attached to the cover 14 to help the feet to have pressure on the rollers.

Title: Improvements in and relating to gypsum products
Inventor: CAVADINO CONRAD GERARD FRANCOI
IPC: C04B28/14
Filed: 1952-02-04
Abstract: Gypsum products, such as wallboards, having a cellular structure, may be made by blending a slurry formed from calcium sulphate hemihydrate and water with a saponified rosinate and a liquid first stage resinous condensation product of formaldehyde with xylenols, phenol, or cresols or any mixture thereof, agitating the blend to product a stable foamed-up mass and drying the mass so formed.  Preferably the weight ratio of the saponified rosin to synthetic resin is from 5 : 1 to 1 : 5, and the solids content of the liquid resin is from 40 to 80 per cent by weight. In the example, a "foaming-up" solution, consisting of a water-diluted blend of a liquid cresol (i.e. a mixture of m- and p-cresols)-formaldehyde resin and saponified rosin was run continuously and simultaneously with an aqueous slurry of plaster of Paris into a mixing machine in which the whole mixture was violently agitated whilst passing through, and from which a material having a cellular structure emerged.  This material was fed continuously between strong paper sheets or liners and the paper coated strip or sheet cut into lengths which were then moved continuously through a drying oven.ALSO:Gypsum products, such as wall boards, having a cellular structure, may be made by blending a slurry formed from calcium sulphate hemihydrate and water with a saponified rosinate and a liquid first stage resinous condensation product of formaldehyde with xylenols, phenol or cresols or any mixture thereof, agitating the blend to produce a stable foamed up mass and drying the mass so formed.

Title: Apparatus for filling a container with rod-like articles
IPC: A24C5/35
Filed: 1975-01-23
Abstract: 1537051 Conveying cigarettes into containers MOLINS Ltd 15 Jan 1976 [23 Jan 1975] 2936/75 Heading B8A Cigarettes in a stream 2 are fed successively by a conveyer 4, inclined conveyer 16, and conveyer 26, and are formed into batches by successive pushers 28 carried by the conveyer 26. The space between the pushers 28 is equal to the length of a pusher 48, which engages successive batches and pushes them into a container 50. The latter is fed vertically downwards to receive successive batches as described in Specification 1,404,141. The pusher 48 is driven by endless chains 56 and 60 (Fig. 2). Moving together with the pusher 48 is a transfer plate 72. This is driven by a pusher 86 on an endless chain 88 against the action of a return spring (78) (Fig. 3, not shown). Part of the mechanism of the transfer plate 72 causes (through a cam 96, rod 94, and linkage 92) operation of catch members 90. These engage each side wall of the container 50 to ensure correct lateral position of the latter as the batch is being pushed into position. The apparatus may be used in reverse for unloading a container 50. In this case the pusher 48 may be in the form of a vacuum head. Controlling flow of the stream on conveyers 4, 16, and 26.-Arms 10 and 12 may move to dot-dash positions to provide reservoir space. This is necessary when the pusher 48 periodically operates, since because of the pushers 28, the conveyer 26 has to temporarily halted. The height of the stream at the downstream end of the conveyer 16, is reduced by the inclination of top plates 38 and 30 being greater than that of the conveyer 16 itself. The height from conveyer 26 to the plate 30 is less by the thickness of one cigarettes than the height of each pusher 28. In order to allow the pushers 28 periodically to pass, the plate 32 is lifted by the action of a cam operated lever 34. The top of the stream above the conveyer 26 is pressed down by an endless belt 40 and by vibrating bars 42. The latter may be replaced by a further endless belt (Fig. 4, not shown). An arrangement is described for feeding a single cigarette depth row to maintain the stream of cigarettes on the conveyer 4 (Fig. 5, not shown).

Abstract: 1427275 Making tubes; extruding; rolling REVERE COPPER & BRASS Inc 22 Jan 1974 [23 Jan 1973] 03006/74 Headings B3A B3P and B3M  A method of forming a tubular product from a preform 10, which includes a body of first material 12 having an aperture (14), Fig. 1 (not shown), in which a deformable mandrel 16 resides, comprises extruding the preform through an extrusion die, annealing the extruded body, and work hardening the annealed body to raise the ultimate tensile strength and yield strength of the body. A titanium alloy billet 12 containing 3% Al and 2À5% V surrounds a mandrel 16, e.g. a carbon steel, which may be bonded thereto by a suitable adhesive lubricant. The conical front end of the preform 10 is engaged with the throat of an extrusion die 24 of a hydrostatic extrusion chamber 20. The titanium alloy extrudant 34 is subsequently annealed at 1300 to 1500 F. for 1 to 3 hours. The extrudant is then subjected to cold working, e.g. ring rolling by rollers (40), Figs. 3, 4 (not shown). The extruded deformable mandrel 36 is removed by grippers and a non-deformable mandrel 46, e.g. of tool steel, is inserted into the aperture and the extrudant is cold worked to give a 25-50 per cent reduction in area using rotatable shear spinning rollers (50), Figs. 5, 6 (not shown). The non-deformable mandrel is removed and the tubing may be stress-relieved by heating for 1 to 3 hours from 600 to 1100 F. Alternatively, the tubing can be annealed at a temperature of from 1100 to 1700 F. for 1 to 3 hours. The lowered yield strength can be raised by an additional shear spinning operation to give a 25 to 50% further reduction in cross-sectional area. The billet 12 may be surrounded with material 60, Fig. 7, to assume a proper volume of hydrostatic fluid 22 for the extrusion.

Filed: 1922-02-04
Abstract: 195,492. Robinson & Son, Ltd., T., and Robinson, C. J. Feb. 4, 1922. Dust, confining in industrial processes; filtering.-Apparatus for separating air carrying dust &c. from grain or granular material and separating the dust &c. from the air comprises an inner vessel in which the grain &c. and air are separated, the grain &c. falling into a hopper below, and an outer annular vessel or vessels ccntaining filter tubes and having below it a dustreceiving and discharging hopper outside the grain hopper, the interior of the sleeves being open to the dust hopper and the chamber bottom outside the sleeves being closed. Air carrying the dusty grain is delivered by a pipe 2 into a chamber 1. The grain falls down the conical bottom, and is discharged by an outlet valve 4. The air carrying the dust flows into the upper part 16 of the casing and is diverted into filter tubes 7, depositing its dust and passing to branches 25 of an outlet pipe 24. The dust is shaken from the filters at intervals by a lever 20 and falls down a conical bottom 21 to a discharge valve 23. The annular chamber containing the filter tubes is divided into two parts, and is closed at top and bottom by plates 9, 10. The upper ends of the filter tubes are carried by rings 14 suspended by rings 15 of flexible material from the plates 9, the rings 14 being carried by arms 18 from the shaking device. The outlet branches 25 are valved and communicate each with one half of the filter tubes, so that either half may be excised from the air circulation and shaken to clean the filters.
