Patent GB-1376345-A (GB)
Title: Quill and spindle assembly
IPC: B23B31/20
Filed: 1971-12-20
Abstract: 1376345 Chucks and spindle assemblies SEIKO SEIKI KK 20 Dec 1971 [26 Dec 1970] 59066/71 Heading B3B A quill and spindle assembly has a collet chuck 26 in a bore 10<SP>1</SP> of a spindle 10 rotatably mounted in a quill 11. A chuck actuating sleeve 41 (Fig. 2) is screwthreaded in the quill and has gear teeth meshed with a gear-wheel 42 so that on rotation of wheel 42 sleeve 41 moves axially and rotationally relative to the quill. An intermediate sleeve 34 is axially fixed and rotatably supported preferably by bearings 35 within actuating sleeve 41 and has a bore with a large diameter portion (right hand end Fig. 1) and a small diameter main part, so that axial movement of sleeves 41, 34 to the right forces a plurality of balls 30 disposed in holes in spindle 10 into tapered holes 29<SP>1</SP> in a further sleeve 29 which is then pushed to the left. Pressure on the collet 26 caused by spring 33 acting through sleeve 29 sleeve 27 and spring 28 is thereby released. Spring 28 aids in releasing the chuck since it acts in opposition to spring 33. Alternatively, if a stronger and variable chucking force than that produced by spring 33 is required the spring is omitted and the chuck is normally in the open condition maintained by spring 28. The right hand faces (Fig. 1) of tapered holes 29<SP>1</SP> engage balls 30 so that movement of sleeves 34, 41 to the right exerts a force on sleeves 29, 27 and closes the chuck. For accurate location of a workpiece in the chuck and the chuck on the spindle, an end cap 25 is somewhat loosely screw-threaded on the spindle 10 but is accurately located by an annular member 24 seated on the spindle at 10<SP>111</SP>. Member 24 may include gear teeth and may be used as a power take-off for a machine. Spindle 10 is driven by means of splined end 10<SP>11</SP>.

The dispenser may be supported on wheels or skids.
Patent GB-2000832-A (GB)
Title: Radial piston fluid rotary machine
IPC: F03C1/04
Filed: 1978-06-23
Abstract: A fluid rotary machine, e.g. a hydraulic motor, has radial pistons (11) and a shaft (2) with an eccentric cam (7) having a rotational movement relative to the housing (1). The cam mounts a ring (8) on the exterior thereof and the pistons (11) abut against the exterior surface of the ring (8) with each piston (11) mounted for sliding movement in the interior of the cylinder (10). The ring (8) is associated with the distribution of the fluid of the machine to the pistons (11) and cylinders (10). Means are provided to immobilize the ring (8) against rotation relative to the housing (1) and subjugate the ring to an essentially circular translation movement relative to the rotational movement of the eccentric cam (7) on which the ring (8) is mounted, and is characterized by the fact that the means for maintaining the ring (8) in such a position comprises a plurality of elastic members (80a to 80e) connecting predetermined points (43) of the ring to anchor points (45) unassociated with the ring. These elastic members (80a to 80e) are sufficiently strong to oppose the tendency of the ring (8) to rotate with the cam (7), but on the other hand, have sufficient elasticity to be adaptable to different eccentricities of the cam (7) when the actual displacement of the machine is being changed. <IMAGE>

Title: Adjusting position of inertia weight in seat belt reels
IPC: B60R22/40
Filed: 1978-10-13
Abstract: A device for use with reel mechanisms for vehicle safety belts. The device serves to activate the locking mechanisms of a vehicle inertia safety belt and comprises an inertia body (18) located in a support (17) and an operating member (20) which is arranged to cooperate with the inertia body (18) and with a mechanism for locking the reel shaft (2) of the safety belt (1). The support (17), the inertia body (18) and the operating member (20) constitute a unit which is rotatable about a horizontal central axis of the support (17) and which is displaceable along an arc having a radius of curvature with the axis of the reel shaft (2) as its centre. Thus the unit can be adjusted relative to the reel depending upon the orientation of the reel as it is fitted in a vehicle. <IMAGE>

Title: Crash-helmet Wire Bag
IPC: A45C13/10
Filed: 1978-10-17
Abstract: A container for a motor cycle crash helmet is formed from multi- strand flexible metal wire (33) resistant to severance in the form of a net assembled by the use of a peg board jig. Points of contact (30) throughout the net are secured together by crimped on metal sleeves. The net forms a bag having only one opening large enough to receive the helmet and bordered by loops (22). The loops (22) are drawn together by a separate wire draw string (37) with looped ends (38) which can be padlocked together after the wire has been passed round part of the motor cycle.

Patent GB-2033012-A (GB)
Title: Semi-rotary internal combustion engines
IPC: F02B75/02
Filed: 1978-10-21
Abstract: The engine has cylinders (2) containing co-axial shafts (3) with pistons in the form of flanges (4) that span the cylinders. Fixed elements (13) divide the cylinders into chambers (14, 15, 16, 17), and a valve member (8) is rotatable to effect opening and closing of ports (9, 10) to each chamber. A sparking plug (18) or fuel injector is positioned adjacent each fixed element. A transmission mechanism translates oscillation of the shafts into continuous rotation of a drive shaft. As a modification the cylinders (2) are mounted in line and served by a common shaft, in which case conventional valves are provided and operated by a cam shaft. <IMAGE>

Title: Metabolite Extraction from Microbial Cells
IPC: C12N1/06
Filed: 1978-11-17
Abstract: Low-molecular-weight metabolites are extracted from cells, for example yeast cells, by disrupting the cell membranes with a cell membrane disruptant, separating the cells from the metabolites that have escaped, supplying the cells with nutrient to restore the level of the metabolites and recycling the cells to the cell membrane disruption step. Suitable cell membrane disruptants are glucose and sugar esters of fatty acids. With sugar esters, the process may be effected as a single-batch, rather than cyclic, process.

IPC: B01D35/027
Filed: 1979-05-21
Abstract: A fuel container (1) of a motor vehicle includes a fuel flow conduit (3) and a fuel return conduit (4) of a fuel circulation system. The inflow side (10) of a filter (5) at the suction end of the flow conduit (3) is kept clean by a scavenging flow of returning fuel being directed by the outlet aperture (9) of the return conduit (4) across the inflow side (10) of the filter (5) and substantially transversely to the flow of fuel being sucked in direction of arrow A into the filter (5). The outlet aperture (9) can be circular in shape or alternatively it can form a fan-jet nozzle. In the latter case a fluidic element in the return conduit (4) upstream of the nozzle can cause the scavenging flow to issue in pulsatory fashion and in a continually changing direction. The aperture can have a plurality of outlet openings so that the filter (5) is washed by streams of fuel in different directions. The flow and return conduits (3,4) can form part of a dip pipe gauge (2). <IMAGE>

Title: Ultrasonic flaw detection of a pipe
IPC: G01N29/26
Filed: 1979-09-28
Abstract: In a method of ultrasonic flaw detection in a pipe, e.g. a heater pipe for catalytic gas reforming with steam, a transmitter probe 3 and a receiver probe 4 suitably spaced axially and angularly one from the other are disposed on the pipe outer surface. The transmitter probe launches ultrasonic radiation upon the pipe outer surface at such an angle that it then passes through the pipe wall straight to another point upon the pipe outer surface. A flaw in the material of the pipe is detected from fluctuation of the received signal, as seen upon scanning the pipe surface by moving the transmitter and receiver probes. <IMAGE>
