Title: Power assisted steering assembly with speed-proportional feel
Inventor: ADAMS FEDERICK JOHN
IPC: B62D6/02
Filed: 1989-08-16
Abstract: Input shaft (7) and a co-axial output shaft (6) are rotatable in response to a steering input and can rotate partially relative to each other to adjust valve parts (8, 10) which control hydraulic fluid to the servomotor. A ball clutch is engageable between the shafts 6 and 7 to restrain said relative rotation. Displacement of the ball (13) to actuate the clutch is controlled by a ball wedge (15) which is biassed against the ball (13) by a spring (16) within the shaft (7). The spring biasing of the ball wedge (15) is adjustable by a rod (19) which is axially displaceable by a screw shaft (23) which is rotatable by a stepper motor (24) in response to input signals derived from a sensor (26) (such as a vehicle speed sensor). In a further embodiment (Fig. 5) the shafts (6) and (7) are displaceable under spring biasing axially relative to each other and the ball clutch (13) is located between profiled surfaces of those shafts to restrain relative rotation between them under spring biasing adjustable by the stepper motor (24). <IMAGE>

Title: Retreading tires
Inventor: SMELKER CHARLES KENNETH
IPC: B29D30/54
Filed: 1990-07-25
Abstract: A process for applying a pre-cured tread stock (62), Fig 2, to a tire carcass 12 in a retreading operation includes rotating the prepared tire carcass 12 on a suitable apparatus 14 and while the tire carcass 12 is rotating a continuous ribbon 517 of cushion gum material is extruded across the crown 12a of the rotating tire carcass 12. The temperature of the cushion gum material must be maintained at a temperature above ambient but below that at which the cure of the cushion gum is initiated. As the ribbon 517 of the cushion gum material 20 is extruded, it is stitched to the tire carcass 12 and a pre-cured tread stock (62) is applied over the cushion gum 20 presented from the crown 12a of the tire carcass 12. Thereafter the cushion gum is cured with heat in order to bond tread stock (62) to the tire carcass 12. <IMAGE>

Title: Holding means for the blade of a microtome
Inventor: KEMPE MANFRED
IPC: G01N1/06
Filed: 1990-08-29
Abstract: In holding means for the blade of a microtome, the blade 6 is clamped between a clamping jaw 3 secured to a base member 2 and a pressure plate 8 which is movable relative to the clamping jaw 3. The culling edge of the blade projects from the holding means and the back of the blade abuts the base of a recess 5b, in a slide 5, which also encloses the blade side edges at least partially. The slide (5) is slidably guided, in a direction parallel to the edge of the blade, in a cavity 3c in the clamping jaw 3. A spring (9, Fig 6) between the slide 5 and the plate 8 facilitates displacement of the slide. A transparent section-straightening plate 20 can yield by means of a spring 22 and can be moved away from plate 8 about shaft 16 and rotated to vary the space between it and the plate 8. A spring-loaded stop (24, Fig. 2) is adjustable to vary the gap between the front edge of plate 20 and the blade 6. A magnetic cover (28, Fig 7) has a flange (28a) shielding the blade edge. <IMAGE>

Title: Storage and retrieval of information in electronic memory
Inventor: MORGAN SCOTT JOHN CHARLES
IPC: G06F12/02
Filed: 1991-11-21
Abstract: A system for storage and retrieval of data, for example. digitised audio signals. is disclosed in which data is handled in a plurality of independent channels D1 - D3. A large electronic storage memory 10 is divided into blocks M1 ... Mn. Prior to the storage of data in the memory a number of blocks sufficient to hold the data are allocated to the channel from which the data is to originate. Once the data is no longer required, each block may be deal located and. in due course, reallocated to a channel to receive another set of data. Each block may be allocated and deallocated independently of other blocks. Allocation and deallocation of blocks for a channel may take place during input, storage or output of data (at O1 - O3) in any other channel, and are controlled by a microcomputer 19. Each channel comprises an input circuit I1 - I3 paired with an output circuit O1 - O3. <IMAGE>

Title: A communications and processing system
Inventor: MARTIN LEO
IPC: G06F13/24
Filed: 1992-12-16
Abstract: A data processing system comprises a host system 1 adapted for communication with sub-systems 2, 3, 4. Each sub-system writes processed data to a process file which is subsequently searched for retrieval of data which is then compressed and written to a transfer file for communication via a modem 26 and switched telecommunications line to a communications controller 12 of the host system. This communication is initiated by a timer which causes transmission of a polling signal from the communications controller 12. The transfer file is automatically monitored in line by the host processor 5 and subsequently processed before selected data is written to fixed disk drives 6 and in parallel to a transfer file (after compression) for transmission to the remote sub-system 2, 3, 4. The system allows the control and monitoring of distributed processing without the need for permanent communication connections or a master-slave relationship between the host and remote systems. Processing and printing of data may occur in parallel. <IMAGE>
