Filed: 1982-08-11
Abstract: A programming device for an automatic sewing machine wherein a succession of stitches are formed by relative movements between a needle and a work holder according to a batch of sewing instructions corresponding to a desired seam or stitch line. The programming device uses a pattern record medium on which the desired line of stitches is registered, and comprises stitch pitch setting means for setting a pitch of the stitches formed along the stitching line. The device further comprises: means for sequentially reading coordinate positions spaced along the stitching line at an interval longer than the pitch set by the pitch setting means; first memory means for storing the coordinate position data read by the reading means; control means for sequentially reading out the stored coordinate position data such that the data of three consecutive coordinate positions are always available, and preparing a series of sewing instructions to form the stitches which are located on a circular arc passing through the three consecutive positions defined by the read-out coordinate position data and which are equally spaced at the preset pitch; and second memory means for storing the prepared sewing instructions. <IMAGE>

Title: Waste paper processing apparatus
Inventor: BAHR THEODOR
IPC: B07B1/55
Filed: 1983-06-07
Abstract: Apparatus for the processing of waste paper comprises a pulper (1) in which the waste paper is pulped, and a perforated filter drum (8) located immediately downstream of the pulper and rotatable about a horizontal axis, in which the fibrous suspension leaving the pulper is sorted, the suspension being introduced at one end and the reject material discharged at the other end of the filter drum. For sorting purposes, where the material density is greater than 12%, the diameter of the perforations of the filter drum, at least in a region adjacent to the inlet (5) is at least 20 mm. The filter openings may be kept clear by means of air blown through air lines (18) onto the drum casing. The apparatus allows a relatively small filter drum to be used at a high material content. Further sorting may be effected in a second drum 12 having smaller perforations than the drum 8. Alternatively, a single drum having larger perforations adjacent the inlet and smaller perforations adjacent the outlet may be used. <IMAGE>

A three-position selector (70) is controlled to connect the front drive shaft (40) to the differential cage (36) (for two wheel drive to the front axle) or to the front quill shaft (52) of the differential (allowing normal central differential action for four wheel drive to both axles) or to both the differential gear cage (36) and the front quill shaft (52) (whereby the differential is locked and both front and rear axles are driven). The differential gear (22) may be planetary and the transmission could include a viscous coupling unit between the drive shafts. The gearbox (5) could be manual or automatic or a continuously-variable-ratio unit. The transmission is more compact and lighter than any other four wheel drive transmission and, when used in a front wheel drive vehicle, can be designed not to intrude into the passenger compartment. <IMAGE>

Title: Handling items to be wrapped
Inventor: SPENCER JOHN KENNETH
IPC: B65B35/20
Filed: 1984-02-07
Abstract: Items (11) in pockets (12) on a horizontal feed wheel (13) are transferred by a pusher (17) at a transfer station (18) in succession upwardly into pockets (14) around the periphery of a wrapping wheel (16) which rotates step-wise around a horizontal axis. Increased rates of item transfer are obtained by arranging for the feed wheel to be driven so as to advance continuously through the transfer station and for the pusher to be driven such that it follows (U,D) the movement of the feed wheel when it projects through a pocket of the feed wheel. In one embodiment, this pusher movement is effected by connecting it to one cam disc (27) which controls its vertical movement and another (36) which controls its horizontal movement. <IMAGE>

Title: Valve spring compressor tools for poppet valves
Inventor: ANDRASSY MARTIN
IPC: B25B27/26
Filed: 1984-07-19
Abstract: A tool (10) for compressing the springs of poppet valves in e.g. i.c. engine cylinder heads comprises a base (11), a frame (12), a slide rail (17) extending horizontally across the frame, a carrier sleeve (24) slidable 12 along the rail (17) and a spring-compressing lever (25) hinged 13 (at 26) to the carrier sleeve (24). The lever (25) can be swung down to engage and compress a selected valve spring in a cylinder head supported on the base (11), over which valve the lever has been positioned by sliding the sleeve (24) along the rail (17). Thus the reaction to the spring-compressing downward thrusts of the lever (25) is transmitted through the carrier sleeve (24), rail (17), and frame (12) to the base (11). The rail (17) is vertically-adjustable by sliding in slots (16) in the frame uprights (13), pegs (20) fitted into selected holes (18) in the uprights locating the rail at the selected height. A range of adaptor plates (37) is provided for the base (11) each plate (37) having a set of bosses (38) to support the heads of the poppet valves of a particular design of cylinder head. <IMAGE>

Title: Information retrieval system
Inventor: HORIGUCHI TOSHIO
IPC: G11B27/32
Filed: 1985-03-19
Abstract: An information retrieval system for retrieving image information with the aid of retrieval information has a non-erasable first record region for recording the image information and a second record region for recording the retrieval information, which are separated from each other. Then, the desired image information is retrieved from the first record region in accordance with the retrieval information. Therefore, important image information can not be erased even if an operation is wrong and a bit unit price of information to be recorded can be made inexpensive. A first embodiment uses two regions of an optical recording disc for the record regions. In a second embodiment the first, second regions are on an optical disc, floppy magnetic disc, respectively. A third embodiment uses a hybrid optical-magnetic disc where the optical, magnetic recording regions are displaced radially from each other on the same disc.

IPC: F16B13/06
Filed: 1986-10-21
Abstract: An expansion anchor is formed from a set of parts including an expansion member 1, an insert member 15 and a split sleeve 8. The expansion member 1 has an inclined surface portion 3 and the sleeve has a laminated body 13. The sleeve is adapted to receive the inclined surface portion 3 of the expansion member 1 at one end and to abut the insert member 15 at the other end, such that when the expansion member 1 is moved towards the insert member 15, the sleeve 8 is expanded over the inclined surface portion 3. The movement of the expansion member 1 towards the insert member 15 may be achieved by providing internal threads on the expansion members 1 and drawing the members together by means of a bolt engaging those threads. The anchor may be set without the use of a bolt by striking the end of the insert member 15 with a hammer and punch. <IMAGE>
