Title: Plasticating apparatus for moulding devices
IPC: B29C45/50
Filed: 1981-05-18
Abstract: Plasticating apparatus (10) operates continuously to plasticate material which is delivered intermittently to a moulding device (34), the plasticating apparatus (10) including a first screw conveyor (18) which rotates in a barrel (12), a backfeed passage (40) within the first screw conveyor (18) and a stationary second screw conveyor (50) in the backfeed passage (40) arranged to recirculate material in a circuit comprising the screw conveyor channel (26), passages (42, 44) and the backfeed passage (40) when the apparatus (10) is not feeding the moulding device (34). The first screw conveyor (18) reciprocates axially so that during periods of non-delivery of plasticated material, the capacity of the circuit is increased by retraction of screw conveyor (18) to the dotted line position to accommodate the accumulation of added plasticated material generated by the continuous rotation of the conveyor (18). A modification of the plasticating apparatus is shown in Fig. 2 (not shown). <IMAGE>

Title: Measurement of foot size
IPC: A61B5/107
Filed: 1981-06-08
Abstract: The invention relates to the measurement of foot size and shape for the accurate fitting of footwear, and is especially useful for feet having abnormalities.

Title: Vehicle with clutch/brake interlock
Inventor: HA JUNG YONG
IPC: B60T7/12
Filed: 1982-10-06
Abstract: In a clutch/brake interlock control system for a motor vehicle, brake fluid is supplied through an inlet (10), a duct (13), a valve seat (12), a chamber (24), a duct (13a) and an outlet (11), from a source to a brake cylinder, upon depression of a brake pedal. The valve seat (12) is closed by a valve closure member (5) under the action of a spring (9) to retain brake fluid in the brake cylinder and the brake applied unless the valve closure member (5) is drawn away from the seat (12) by a solenoid armature (8) which moves upwards under the action of a stronger spring (9a) when a solenoid coil (3) is deenergised.

Title: Method of burning low calorific gas and burner for low calorific gas
Inventor: ENAMITO SATOSHI
IPC: F23D14/22
Filed: 1983-01-14
Abstract: A low calorific gas which has poor combustibility is divided into two parts including a small part for a pilot flame and the remaining part of the main combustion. The released heat from the stable burning pilot flame is utilized to maintain the burning of the low calorific gas for the main combustion. Changes in the operating conditions of the burner are adjusted by the control of the flow rate of the low calorific gas for the main combustion, so that stable high load combustion flames can be obtained over a wide scope of operating conditions. Liquid fuel is supplied to an atomiser via a passage 6. Air for the pilot flame is supplied to swirlers 2A via passages 9-11. Low calorific gas for the pilot flame is supplied to apertures 3A via passages 12, 13. Low calorific gas is supplied to swirlers 4A via passages 14-16. Air for main combustion is supplied to swirlers 5A via passages 9, 17. <IMAGE>

Title: Braking reel during unwinding
Inventor: GROSSE KARL
IPC: B65H23/06
Filed: 1984-03-15
Abstract: Reel braking is controlled by tension changes in the unwound material. A reel (B) from which material (P) is unwound is braked by a shoe (19) applied by a spring- biased pivoting lever (14). Rollers on a spring-biased rocker arm (5) guide the material. Tension changes rock the arm, whose movement is limited by a stop (6). The arm rotates a hub within a rotatable housing (8), the hub engaging the housing via spring-urged friction discs. A pin-and-slot connection allows movement between the hub and discs. Housing rotation urges a housing roller (8b) against an adjustable torsion spring (17) on the lever (14) to apply the brake. A stop (12) limits housing movement. The arrangement allows even material feeding, with damped brake actuation. <IMAGE>
