Title: Improvements in a receiving tube for cup forming machines
Filed: 1921-05-25
Abstract: 185,183. Rogers, F. H., (Vortex Mfg. Co.). May 25, 1921. Paper bags and the like, making.-A receiving-device for the completed cups ejected from the forming-rollers 12, 14 of a cupforming machine, such as described in Specification 176,963, comprises a removable receiving tube 24 to which the cups are delivered by a shoot 18, 22. The tube has a slidable bottom 28 having a bifurcated end 29 carrying a removable member 30 upon which the cups are delivered, the bottom being lowered automatically by a predetermined distance at each reciprocation of the blankfeeding table of the machine, so that the cups are correctly stacked one within the other. The bottom 28 is carried by a cable &c. 38 passing around a drum 40 and connected to a weight or piston 36 sliding in a cylinder 34 disposed parallel to the table 24, the bottom being guided by a rod 32 and the exterior of the cylinder 34. A ratchet-wheel 48 fixed to the axle 47 of the drum is actuated by a ratchet 52 carried by a lever 62, 66 pivoted on the axle 47 and connected by levers 70, 78 with a member 80 of the means actuating the blank-feeding table. Backward movement of the ratchet &c. is prevented by a spring pawl 54. The bottom 28 projects through a vertical slot 26 in the tube 24 so that, when full, the latter with the member 30 may be removed and an empty table placed in position against the stop 25.

Title: Process for softening textile materials
IPC: D06M13/224
Filed: 1959-04-30
Abstract: Textile materials, e.g. filaments, fibres and fabrics of cotton, rayon, polyamides, polyacrylonitrile and polyesters, are softened by treatment with an ester of a fatty acid of 6-30 carbon atoms and a di- or tri-saccharide, e.g. sucrose, maltose, lactose or raffinose. The textile material is immersed in an aqueous liquid containing 0.2-1.5 g. of the ester per litre.  The treatment is advantageously carried out in the presence also of an amidamine prepared from a high mol. wt. carboxylic acid, such as lauric, stearic or oleic acid, and a polyamine such as 3-dimethylamino- or 3-diethylamino-proplyamine. Examples describe the treatment of spun rayon, knitted fabric of polyacrylonitrile fibres and cotton fabric by immersion in aqueous solutions of saccharose monostearate, saccharose distearate, a saccharose-coconut oil reaction product and a cane sugar-tallow reaction product.

A laminated stator assembly for an electric motor is built up from a plurality of laminations each comprising a peripheral yoke portion 2 and a polepiece portion 1 having a stator field core portion 3, the polepiece portions and the yoke portions being formed with complementary parts shaped to effect keying or interlocking engagement with corresponding parts of similar laminations, the form of the laminations being such that two (as shown) or more may be arranged so that their polepiece portions define a rotor aperture and so that a part of a polepiece portion engages a corresponding part of the yoke portion of the circumferentially adjacent lamination so that the assembled laminations present a continuous outer peripheral magnetic circuit, in which the keying or interlocking is such that separation of the laminations in a radial direction with respect to the rotor axis is prevented. The field core portions 3 are so shaped (parallel-sided, as shown), that a field coil 7 may be directly fitted thereon prior to assembly of the two halves. As shown, the upper yoke portion is integral with the lower polepiece portion, the dividing lines being 4, 5, and the dovetails and grooves. Four-pole and six-pole laminations are described, the constituent parts in each case being identical. The polepiece portions 1 may be slotted near one side to permit shading rings to be fitted.

Control valve actuating means for vehicle power assisted steering gear comprises a hub 28, Fig. 2, attached to steering wheel spokes 27 and rotatable on steering shaft 29. The hub engages by dogs 31, a collar 33 having helical teeth or splines engaging similar teeth or splines, 34, on the shaft. A groove 33a in the collar contains a split-ring 36 having stubs 37 engaging a yoke 24, Fig. 1, pivoted at one end to a fixed arm 25, and pivotally engaging at its other end a rod 26 connected to the valveoperating member. Rotation of the hub causes axial sliding of collar 33 and hence axial movement of the rod 26. The collar is slidable between limits in which it engages an abutment 35 or the dogs are fully engaged, so that manual steering is possible if the power fails. Ring 36 may be replaced by slippers or rollers carried by yoke 24. The valve may be pre-loaded so that power assistance occurs only when a predetermined steering torque is exceeded, the valve being restored to its neutral position when movement of the steering wheel ceases.

Abstract: 652,479. Resilient mountings; vibration dampers. DUNLOP RUBBER CO., Ltd., June 5, 1948, No. 15250. [Class 108(iii)] A resilient mounting comprises a base member, a coaxial displaceable member resiliently connected thereto and adapted to oscillate along the common axis of the two members and damping means comprising a friction surface resiliently connected to one of the members and a complementary friction surface associated with the other member, the friction surfaces being parallel to each other and inclined to the common axis and being spaced apart but adapted to make frictional contact if a predetermined amplitude of oscillations is exceeded. In the arrangement shown, a flanged tubular member 15 is supported, through a bonded rubber annulus 18, on a central tube 7, carried by a cylindrical base member 1. A plurality of metal segments 11 which are bonded between their adjacent faces, and to the member 15 through a rubber member 14, are provided with inclined outer friction surfaces 13 which lie parallel to and, for normal vibrations are spaced from, a complementary inclined inner surface 6 of the base member 1. The tube 7 is adjustable relative to the base member 1, to vary the space between the friction surfaces. In another arrangement (Figs. 3 and 4, not shown), the base member and segments are each provided with a pair of axially disposed opposing frusto-conical complimentary friction surfaces by which excessive amplitude vibrations are damped during relative movements of the base member and flanged tubular member, in either direction. In a modification of this arrangement, the segments are divided circumferentially into two equal parts and have rubber bonded between them. In both arrangements the friction surfaces may be of impregnated asbestos and the bonded rubber may be a synthetic rubber composition preferably of an oil-resistant type. The friction surfaces may be other than frusto-conical, e.g. pyramidal.

The refrigeration system for the freezer includes a compressor and condenser unit 10, 11 and an evaporator 8 disposed in the space 7. The freezer also includes a source of liquid refrigerant gas 28, e.g. liquid nitrogen, and a number of perforated pipes 26 connected to the source 28 for the direct admission of the liquid gas into the cabinet for rapid freezing purposes. Excess gas may pass out of the cabinet through discharge pipes 29. One or more motor driven fans 9 are located at the base of the space 7 to draw gas through passageway 19 up through the space 7 over the evaporator 8. Each fan 9 is driven by a motor 14 arranged beneath the fan blades in a housing 15. The housing has an open top and a bottom which slopes towards a central drain aperture 17. The housing acts to thermally insulate the motor 14 for the refrigerant gases passing around the cabinet. In operation of the freezer, goods stored in space 13 on a trolley 22 are frozen initially by gas from cylinder 28. The mechanical refrigeration system is brought into operation after the supply of the liquid gas to the pipes 26 has been shut-off. The fan or fans 9 may be operated during both the initial rapid freezing stage and the subsequent normal refrigeration stage.
