Title: Improvements in and relating to processes for the treatment with organic solvents of animal fibres, such as wool, and structures made therefrom
IPC: D01C3/00
Filed: 1929-10-21
Abstract: In cleansing wool, hair, and other animal fibres, and articles made therefrom, water-soluble solvents are used with added water to depress to the desired extent the solvent action on the wool fat. Hair fat or wool fat may also be added to prevent the removal even of traces of such fat, e.g. when specks of tar &c. are to be removed from wool.  Aqueous solutions of acetone or pyridine are specified. If rapid removal of the tar is required, other solvents may be added, e.g. 10 parts of trichlorethylene to a mixture of 10 parts water with 50 parts of pyridine. Specification 266,436, [Class 91, Oils &c.], and the use of trichlorethylene, carbon disulphide, acetone, methyl acetate, and methyl alcohol, are referred to.ALSO:Bleaching and washing, processes and materials for.-In treating wool and other animal fibres, and structures made therefrom, with organic solvents for extraction purposes, water is added to water-soluble solvents to depress more or less their solvent action on the wool fat.  If the solvent solution is saturated with wool fat, it may be used to extract specks of tar &c., from the wool.  By adjustment of the amount of water added, the solvent may be arranged to extract just the required amount of fat at the temperature at which extraction is effected.  If rapid removal of the tar is required, substances which are not themselves water solvent may be added to the mixture, for example, 10 parts of trichloroethylene may be added to a mixture of 10 parts water with 50 parts of pyridine.  Specification 266,436, [Class 91, Oils &c.], is referred to.

Title: Improvements in shock-absorbing suspension means for vehicles and the like
IPC: F16F9/096
Filed: 1956-10-23
Abstract: 872,885. Hydraulic shock absorbers. GILL, P. D. Oct. 18, 1957 [Oct. 23, 1956], No. 32233/56. Class 108(3). The main hydraulic compartment of a suspension unit is connected to at least two secondary compartments via respective orifices of pre-set area. The arrangement is such that the spring rate of the unit will be directly proportional to the velocity of the applied blow. In Figs. 2, 2a two vessels 22, 29 contain oil in chambers 25, 31, and air in chambers 24, 32, the oil and air being separated by flexible diaphragms 23, 30. The chambers 25, 31 communicate with the interior of working cylinder 10 via passages 26, 23, the latter being restricted by a valve 34. In operation oil is forced by piston 11 from the working cylinder into chambers 25, 31 to compress the air in chambers 24, 32. If the piston moves slowly, oil from the working cylinder will enter both chambers 25 and 31, but if the piston moves quickly, oil will enter chamber 25 in greater quantities than chamber 31 thus providing harder springing. The two vessels 22, 29 may be differently shaped and contain air at different pressures to provide different spring characteristics, in addition the size of passages 26, 33 may be altered. Coil springs may be used instead of air springs (Fig. 3, not shown) pistons transmitting oil pressure to the springs. Fig. 4 shows an arrangement which ensures that the oil remains cool by circulating from reservoir 48 to working cylinder 26a and back to reservoir 48 through chambers 25a, 31a and non-return valves 46, 47, 49, 50. The invention may include a self levelling mechanism as described in Specification 26115/56.

Title: Improvements in sausage-filling machines
IPC: A22C11/06
Filed: 1927-11-30
Abstract: 303,254. Wright, F. H., and Lewis, E. W. Nov. 30, 1927. Hydraulic presses.-A sausage filling machine is operated by an hydraulic press controlled by three valves, one valve for admitting fluid to the press, one for byepassing the press when the press is temporarily inoperative, and one for discharging fluid from the press during the return stroke. The fluid is preferably oil and is contained in the bottom of the space between the press 12 and an outer casing 19, a filling opening 50 being provided. A motor 47 drives a gear pump 20 through worm gearing 28, 28a and a shaft 48 which carries one of the pump gear wheels 21. The pump has a suction pipe 23, Fig. 3, and delivers oil to a valve box 25 containing two valves 26, 37. The valve 26 is a byepass valve normally kept open by a spring 29, and is closed by a pedal 36 connected thereto by links 30, 32, 35. When the pump is working and the valve 26 is open, the oil passes up a pipe 27 having a downturned end to discharge the oil over the worm gearing which is thus lubricated. When the pedal 36 is depressed and the valve 26 is closed the oil passes into the press, for the working stroke, through the spring-loaded valve 37. The oil is discharged from the press through a valve 39, normally closed by a spring 40, which is opened by an eccentric stud 42 on the rotary handle 45 engaging the end of the valve stem 41. The working stroke is automatically ended by the ram 18 contacting with a pivoted trip lever 41<a> having a bifurcated end 41b engaging a collar 41<c> fast on the valve stem 41, the valve 39 thus being opened. The valve 39 may be mounted on the valve box 25.

Abstract: 1,148,465. Electro-magnetic brakes. DSO "BALKANKAR". 19 July, 1966, No. 32474/66. Heading F2E. [Also in Division H2] In a motor-brake unit for operating a hoist through gearing, the conical rotor of the motor is mounted on a hollow shaft 4 which also carries the brake 5. A spider 9 resiliently coupled at 12, 13 to the brake-cone, is secured to a torsion shaft 3 passing through the hollow shaft 4 to the load. On heavy load, torsion of the shaft 3 enables the hollow shaft to transmit the load by the engagement of a dog-coupling at 2, but if the load becomes excessive, the angled teeth of the coupling drive the hollow shaft axially to engage the brake and operate a cut-out 23. Smooth application of the brake is ensured by pneumatic dampers 8 adjusted by valve 11. Alternatively more elaborate hydraulic dampers may be used (Figs. 3-5, not shown). Axial play between the brake-cone and driving spider 9 is allowed by rubber rollers 12 on the spider, but an alternative elastic coupling is described (Fig. 6, not shown).

Abstract: 1,115,892. Fluid-pressure brakes. ROBERT BOSCH G.m.b.H. 30 July, 1965 [1 Aug., 1964], No. 32599/65. Heading F2F. A fluid-pressure brake servomotor, particularly of the vacuum-suspended type, has a follow-up type valve, the pedal-operated element of which comprises a sleeve 11 which is guided both in a plastic bush 21, retained by a seal 23 and ring 24 within a short neck 22 formed on the front end 2 of the cylinder 1, and in a guide plate 20 welded to the piston 3 of the servomotor, and a valve closure member 30, guided on a rod 8 within the sleeve 11, is urged by a spring 33 against one or other of two valve seats 31, 32 carried by the sleeve and piston, respectively, according to the relative positions of the sleeve and piston during brake operation, as determined by the pedal and reaction forces. The latter are communicated to the sleeve 11 via a plurality (three, as shown) of levers 4 arranged radially with their mid-portions engaging a rib 49 of the output member, which comprises a plate 5 and a rod 6, their outer ends engaging a rib 48 of the piston and being apertured to receive studs 50 secured to the piston, and their inner ends engaging a collar 7 on the rod 8. The latter has a socket and flange 9, at its forward end, this, together with another socket element 12, enclosing a ball 15 on the rear end of a pedal-operated rod 16, and being located against a shoulder 10 of the sleeve by a sleeve 13 and circlip 14. Springs 51 surrounding the studs 50 act between pins 53 carried by the studs and the plate 5, so that in the inoperative position levers 4 urge the sleeve 11 to a forward position determined by engagement of a stop ring 26 with the guide plate 20, in which position vacuum connected at 43 to the forward chamber is also communicated to the space behind the piston 3. When the pedal is operated, sleeve 11 moves rearwardly so that closure member 30 engages seat 32, and seat 31 then leaves the closure member to admit air via apertures 41, 42 to the space behind the piston to operate the servomotor, reaction forces acting through the levers subsequently determining a lap position of the valve. As the sleeve follows up piston movement, the two bearing surfaces provided by bush 21 and plate 20 become further apart so that the reaction forces are adequately sustained in spite of the short guide surfaces these members provide.
