Title: Improvements to seals between relatively rotatable parts
IPC: F16J15/36
Filed: 1979-11-16
Abstract: A rotary face seal assembly comprises a face seal (14) sealed into a recess (15) in an annular seal component (10) which engages a housing so as to form a fluid-tight seal between the housing and the seal assembly. The face seal component (14) is adapted to engage a counterface component mounted on a rotary shaft (not shown). The seal between the annular seal component (10) and the face seal (14) is effected by means of a bead (17) formed on one surface which is compressed into a groove (18) of trapezoidal section formed in the other surface. The face seal component (14) and annular seal (10) are held in close contact by a rigid element (19) bonded to the annular seal component (10). Unintentional displacement of the face seal component (14) is prevented by a lip (20), formed on the recessed portion (11), which extends over the face seal component (14). The face seal assembly may be mounted on the rotary shaft with the counterface component being mounted on the housing. <IMAGE>

Title: Strapping machines
IPC: B65B13/22
Filed: 1979-11-27
Abstract: A strapping machine for binding packages with metal or plastics strapping (8) has a tensioning device (6, 7) which is driven by an electric motor (1) coupled to the tensioning device (6, 7) by a hydrodynamic coupling (4) which delivers maximum torque with its output stalled but while its input is still rotating and such that the motor (1) is not overloaded even though the tension is maintained for an appreciable time. The maximum output of the hydrodynamic coupling (4) can be adjusted by altering the quantity of hydraulic fluid it contains either initially or by a fluid control circuit which causes fluid to flow into or out of the working chamber of the coupling (4). <IMAGE>

Title: Brake pressure modulating valves
IPC: B60T8/36
Filed: 1979-12-13
Abstract: An anti-skid modulating valve i) of the kind shown in Figure 1 with an inlet 7 and an outlet 8 to a brake cylinder. An expander piston is moved to the right by a spring 10 to close valve 5 and expand the volume of the chamber 9, so reducing the brake pressure. The piston is normally held in the position shown by a solenoid 6. In the modification according to the invention (Figure 2), the piston is in two parts 3a and 3b. A spring 12 urges them apart, causing detents 11 to lock the part 3a to the housing 13. When the solenoid 6 is energised, the parts 3a, 3b move together against the force of the spring 12, and if the solenoid is subsequently de-energised, the composite piston can move to the right to reduce the brake pressure. <IMAGE>

Title: Method of Treating Vegetable Raw Materials Containing Thioglycoside
IPC: A23L11/30
Filed: 1980-10-07
Abstract: The invention relates to a method of treating vegetable raw materials containing thioglycoside, particularly brassica and crambe seeds. According to the invention, vegetable thioglycoside-containing raw materials, particularly brassica and crambe seeds and processed products thereof, are pre-crushed, possibly conditioned, flocculated and subjected to repeated extraction with ethanol under pressure, at a boiling temperature corresponding to the excess pressure applied, with a view to obtaining oil and reducing harmful materials. With alternating pressure and relief from pressure after each ethanol treatment, the oil-containing micell is separated at the high pressure, whereupon the extraction residue, still under pressure, is abruptly relieved of pressure. The method removes lipids and thioglycosides as completely as possible from brassica and crambe seeds and processed products thereof, in one operation for obtaining a high quality oil and extracted husk which is substantially free from anti-nutritive constituents.
