Title: Conveyor car and other vehicles having power operated auxiliary equipment
Inventor: HYDE RONALD WILLIAM
IPC: F02B3/06
Filed: 1984-03-22
Abstract: A conveyor car has a diesel traction engine 2, a hydraulic pump 12 in its hydraulic circuit for driving the conveyor, a battery operated electric motor 22, and an auxiliary pump 24, such that the drive for the conveyor can be derived from the diesel engine or from the electric motor selectively. Thus with the car stationary, the conveyor is driven from the battery 21, but if this fails the conveyor can be driven from the engine. A single pump can be driven selectively by the engine or the motor. In place of a conveyor the vehicle can have other auxiliary equipment and the drive can be other than hydraulic. <IMAGE>

Title: Apparatus enabling efficient utilization of a memory for storing image data of plural pages
Inventor: HISADA KATSUTOSHI
IPC: G06T1/60
Filed: 1984-05-24
Abstract: In an image processing apparatus for electrically handling image information, particularly in compressed form, the efficiency of memory utilization is improved by storing information of plural pages in successive manner in a memory. The apparatus operates so that the memory area into which the image data (preferably compressed) of a page is stored corresponds only to the area required for the storage of said data i.e. not to a predetermined area. For example, a first page of data is stored for address A to address B in a memory having addresses A to Z, a second page is then stored in a memory area immediately following the memory area used for the first page i.e. from address B to address C. Since a third page would require more memory area than that from address C to address Z, this page is not stored until the data of the first page has been read from the memory for transmission to a printer.

Title: Device for producing large-picture assemblies
Inventor: DEY DIETER
IPC: H04N19/23
Filed: 1984-07-02
Abstract: A large-picture display, e.g. for vehicle (e.g. ship) simulation, is provided by recording new data from a pick-up sensor such as a static or rotating TV camera, e.g. with linear or areal mosaic CCD receptor, which views a model or real panorama. Picture processing removes overlap or fills gaps, leaving a modular set of fields, each e.g. 8 &cirf& 5 DEG  x 8.5 DEG , recorded on video disc. In use the discs (50) are read out and digitized (51) to multi-bit RAMs (52) from which the data is read out for display (58), the whole system being under control of processor (59). Change of aspect is provided by varying the addressing of RAMs (52). A separate disc channel (50') is provided for moving objects, with priority according to nearness so that background and remote objects can be obscured. Selected multiple fields may be displayed on stacked picture screens, or by back projection. <IMAGE>

Title: Big bale baler for agricultural crop material
Inventor: ACKERMANN GUSTAV
IPC: A01F15/07
Filed: 1984-07-02
Abstract: A big bale baler 1 with driven winding rollers 3 which define the baling chamber at the periphery thereof includes a storage container 6 for a roll 7 of web material from which, after a bale has been formed, the leading end of the web can be passed by means of feed rollers 8, 9 into the baling chamber through a feed-in gap defined by two winding rollers. It is then gripped by the winding rollers and the finished bale itself so that the bale, in conjunction with the winding rollers, draws from the supply roll the length of web material necessary for winding around the bale, the feed rollers being in a non-driven mode in that operation. The revolutions of the feed rollers are detected by a counter (47, Fig. 6) which can be preset and, when a given number of revolutions of the feed rollers is reached, the operations of automatically severing the web by means of a blade and automatically ejecting the bale from the baler are initiated. <IMAGE>

Title: Self-locking releasable lock nut
Inventor: CHAVEZ ALEX B
IPC: F16B39/24
Filed: 1985-02-25
Abstract: A locknut 31 is screwed onto the screwthread 15 of a shaft 11 (or bolt) to clamp a ring 14 (e.g. a wheel bearing) to the shaft 11, the locknut 31 then being locked by having its teeth 35 engaged by the teeth of a spring-biased lock ring axially movable but prevented from rotating by means of tangs projecting into axial slots in a thrust washer 22 keyed to the shaft 11, the interengaging teeth being so formed that sufficient torque applied to the locknut 31 will cam the lock ring away from the locknut 31 to release it. The locknut 31 can be operated by any pronged tool engaged with axial grooves in its outer periphery, or by a special tool provided with prongs to push the lock ring axially. The teeth may be formed asymmetrically so that loosening is more difficult than tightening.

Abstract: Apparatus for stimulating the cochlea to give a sensation indicative of the pitch of voiced sounds is known and apparatus is described for adding stimulation in response to voiceless sounds. Signals from a microphone passing by way of an amplifier and a bandpass filter 99 reach a zero crossing detector 103, and intervals between successive crossings are measured using counters 104 and 105 and circuits 97, 98, 98', 117, 118 and 118'. Successive intervals found in this way are compared with absolute values in comparators 107, 107' and 108, 108' to determine when successive intervals are comparatively short, indicating voiceless sounds, and comparatively long indicating voiced sounds, respectively. A random noise source 13 is connected to stimulation circuits when voiceless sounds are detected, connection being by way of a switch 113 controlled by logic circuits 110 to 116 and 116', and 119 and 119' from the comparators 107, 107', 108 and 108'. <IMAGE>

Title: Liquid pump
Inventor: LAMPARD ROBERT DOUGLAS
IPC: F02M41/06
Filed: 1985-07-02
Abstract: In a two-stage fuel pump (14) liquid fuel passes via gear pump (24) and radial piston pump (28) to two similar metering fuel distributors (32), (34). Delivery from piston pump (28) is variable by means of an eccentric piston drive arrangement such that maximum delivery occurs under reduced speed conditions, such as engine cranking or heavy load. Distribution (32), (34) comprise hollow cylindrical members (230) in which rotate spindles (234) driven from gear pump (24). The spindles (234) have cavities (300), (302) which periodically align with an arrangement of ports through the walls of members (230). As spindles (234) rotate, fuel is alternately received into and delivered from cavities (300), (302) metering and delivery being effected by a slidable pin (304) which axially reciprocates through spindle (234) to intrude a controllable variable amount into cavities (300), (302) under alternately applied fuel pressure to effect variable fuel displacement. Provision is made for varying the timing of fuel displacement by variation of the angular displacement of the spindle (234) of the distributor (32) relative to its drive shaft (90) from the gear pump (24).

IPC: B22D39/00
Filed: 1987-09-29
Abstract: A die-casting machine has a shot sleeve (10, or 26) with a charge hole (9, or 25) to which a molten metal charge is delivered at the start of each casting operation. The charge is previously melted by induction heating, and in one form rests in a pivoted ladle (1) surrounded by the heating coil (2). The solid charge, cut from stock to the precise amount, is gravity delivered and, when melted, the ladle is tilted to pour directly into the charging hole (9). Alternatively, the charge is supported within an upright induction heating coil (21) by electromagnets (22) and, when molten, current switch-off causes the charge to drop directly into the charging hole (25). The apparatus can be inert gas shielded, and automated to run continuously, a charge being melted as the previous one sets in and is released from the die. <IMAGE>
