Abstract: 1299376 Slack adjusters GIRLING Ltd 20 Aug 1970 [21 Aug 1969] 41756/69 Addition to 1179235 Heading F2E A slack adjuster for a shoe drum brake or spot type disc brake has frictional surfaces 43, 44 respectively formed on a non-rotatable member 22 engaging, in the example shown in Fig. 1, one shoe 12 of a shoe drum brake, and the conical domed head 34 of a screw member 32 having a reversible helically threaded connection 33 with an intermediate rotatable sleeve 21 threaded to a further non-rotatable member 20 engaging the second shoe 11. Surfaces 43, 44, do not engage upon actuation of the shoes until wear occurs at which point they engage one another to prevent further movement of threaded member 32, the reversible threaded connection 33 of which causes sleeve 21 to rotate slightly to adjust threaded connection 29 in a direction to take up slack. In other embodiments the reversible threaded connection 33 is provided between the screw threaded member 32 and end member 22 and the conical friction surface 43 is on the sleeve 21. In the embodiment shown in Fig. 4 for a spot-type disc brake sleeve 21a has an external non-reversible screw thread connection 29a with an actuating piston 51 equivalent to the member 20 and the adjuster operates as in the embodiment for the shoe drum brake. In a further embodiment for a shoe drum brake, Fig. 6 (not shown), member 21 is in the form of a sleeve which has the non- reversible screw-threaded connection 29 with a spindle (28) and a nut (64) is fixed to one end of the sleeve. The reversible screw thread 33 is provided between nut (64) and member 32 and the abutment surfaces are provided on sleeve 21 and a bush (69) disposed in a blind bore (67) housing part of the adjuster. An hydraulic and an auxiliary hand actuator are provided.

Title: Process for producing a gold coloured iron material
IPC: C22C32/00
Filed: 1958-12-29
Abstract: Relatively pure iron powder, prepared by contacting impure iron powder with calcium in an inert atmosphere, is mixed with a colouring agent comprising red lead or cuprous oxide and sintered at 800 DEG to 1300 DEG  C. in vacuo or an inert gas such as argon to form a gold-coloured product.  One or more of the oxides of Sn, Co, Mn, Cr, Fe, Ni, W or Os may also be added to the powder.  In an example 0.02 kgm. of red lead (250 mesh) or a mixture of cuprous oxide and stannous oxide is mixed with 10 kgm. of iron powder, composted at 3-3 1/2 ton/cm.2, sintered at 800 DEG  C. under argon and after cooling under argon to 300 DEG C. under argon and after cooling under argon to 300 DEG  C. is forged.  The pure iron powder is formed from 250 mesh Swedish steel powder which is reacted with calcium powder under argon in a platinum lined iron vessel.  After stirring and standing for 24 hours the purified iron powder was separated by elutriation. Specification 913,198 is referred to.

Title: Centrifugal type thresher
Inventor: WITZEL HOMER DANIEL
IPC: A01F7/00
Filed: 1960-12-10
Abstract: 895,885. Threshing machines. HARVESTAIRE Inc. Dec. 10, 1960, No. 42599/60. Class 6(3). [Also in Group II] A threshing machine includes a separator for the threshed products comprising a generally tubular foraminous or gridded drum 56 having an inlet 40 to receive the grain products and having rotary members 28, 74 which serve to throw the grain radially through the drum over approximately 360 degrees and to pass straw axially to an outlet 104. As shown, an elevator 42 feeds the cut crop to the inlet 40. The member 28 comprises a fan having a central disc 48 which prevents grain stalks from entering the fan axially. The disc has serrated radial bars 50 thereon, which agitate the grain and prevent bunching. The fan blades 30 thresh the grain and force it through a conical part 60 of the grid 56. Any grain not passed through the part 60 passes, with the straw, into the cylindrical part 76 where a more rapidly rotating cylinder 74 having helical lines of bristles 80 thereon urges grain through the grid and the straw to a discharge outlet 104. The grain and chaff are passed by a hopper 70 to a chaffseparator 24 having a fan 170, grid 140, rotary brushes 164, and disc 160 to prevent axial flow direct to the fan. In this case the fan 170 is rotated more rapidly than the disc 160 to which the brushes 164 are attached. The disc, brushes and grid are separated by a partition 148 from the compartment containing the fan and which has a chaff-discharge outlet 176. The grain is further cleaned in a smaller unit 26 identical in construction with the chaffseparator 24, unthreshed ears being returned through a pipe 212 to the grain-inlet 40. In modifications, the members 74, 76 are frustoconical and the brushes 80 are replaced by spring tines preceded by rubber flaps.

Title: Vehicle braking systems
IPC: B60T13/12
Filed: 1975-10-23
Abstract: 1490605 Hydraulic brake booster systems DAIMLER-BENZ AG 23 Oct 1975 [30 Oct 1974] 43650/75 Heading F2F On failure of a booster 3 the transmission ratio is reduced of an associated device between a pedal and a master cylinder 6 and comprising a pressure medium chamber 22, an input piston 21 and an output piston the effective diameter of which is increased by operation of a switch controlled retainer. The device (1, la) may be on either side of the booster 3 (Figs. 1a, 1b, not shown). In one construction, Fig. 2a, movement of an input piston 21 normally displaces a piston 19 within an outer piston 20 but on booster pressure failure a solenoid lifts a retainer 14 when the pistons 19, 20 move together at a slower rate. The pistons 19, 20 may be co-axial or spaced apart radially of one another. In a second construction, Fig. 3c, the outlet piston 28 is a master cylinder piston and has a bore 36 containing a piston 37 communicating with a reservoir through an annular passage (35), a port 29 and a one-way valve 32. Normally the piston 37 is at the outer end of the bore 36 and the valve 32 is closed preventing escape of fluid from the bore 36. When the input piston 34 is moved into the chamber 38 its extension contacts the piston 37 which it moves together with the piston 28. Further fluid enters the enlarging chamber 38 through a port 41 and past the one-way seal 42 on the piston 34. On brake release, fluid escapes from the chamber 38 through a further one-way valve 33. On booster power failure solenoid actuated retainers 44 open the valve 32 and close the valve 33. On movement of the piston 34 the piston 37 moves to the bottom of the bore 36 due to its smaller area than the piston 34 after which the piston 28 is moved at a slower rate than the piston 34 due to its greater area until the piston extension comtacts the piston 37.

In the embodiment shown, two sets of mirrors 8, 5 are used, the coded information pattern read out from a hologram 8 on to array 6 being represented by lines RO, and the zero-order beam being reflected by a pair of mirrors 8, 5 on to the next hologram 8. As each information block is received by array 6, a clock generator 31 advances a counter 33 which, together with an address register, enables a read-out gate 29 to select the required information block. An automatic gain control 35 compensates for losses in the system. The positions of the mirrors 5 may be adjusted to vary the time separation of the blocks. In a second embodiment, Fig.2 (not shown) an array of detectors is provided on each side of the hologram plane and successive holograms are read out on to alternate arrays as the light pulse makes successive traverses of the hologram plane. Further hologram planes may be included. Read-out times in the nano second range or below are said to be possible.
