Title: Navigation System Receiver
IPC: G01S1/30
Filed: 1982-02-15
Abstract: A receiver for a navigation system such as the "Decca Navigator" system comprises an aerial (1), an aerial filter (2), a buffer amplifier (3) and a plurality of tuned amplifiers (4, 5, 6 and 7). Two balanced demodulators (8-1, 8-2), which are each controlled by two local oscillator signals of opposite phases, are connected to the output of each amplifier. The two signals (0 DEG , 180 DEG ) which control one demodulator (8-1) are in a ninety degrees phase relationship to the signals (90 DEG , 270 DEG ) which control the other demodulator (8-2). These signals are derived from a frequency synthesiser (12) which is connected to a non-synchronized source of local oscillator signals (13). Low-pass filters (14, 15) are connected to the outputs of the demodulators. The outputs of said low-pass filters are connected to a signal multiplexer (16), the output of which is connected to a A/D-converter (17). The output of said converter is connected to a processor (18). The processor converts the information of the navigation signals into position co- ordinate information. Display means (19) shows the position information in longitude and latitude. The receiver does not require a synchronised local oscillator. <IMAGE>

IPC: B41F15/08
Filed: 1982-10-08
Abstract: A screen-printing apparatus suitable for multi-colour printing, including two or more printing stations (2, 4) at each of which an image is printed onto a substrate (6) by transfer from a printing screen (18, 28), means for conveying the substrate along a pathway which leads successively to each printing station, each printing station (2, 4) including a printing cylinder (14, 24) over which the substrate passes and is brought into contact with the printing screen (18, 28) for transfer of the image during simultaneous forward movement of the print screen (18, 28) and of the substrate (6), the said pathway having a spiralling configuration such that at each turn of the spiral it passes sequentially through one of the printing stations (2, 4), the pathway being arranged so that the distance of travel of the substrate between printing stations (2, 4) is of sufficient length for the printed image to dry before further printing takes place, and means (46, 50, 56) for coupling forward movement of the substrate (6) with forward movement of the printing screen (18, 28). <IMAGE>

Title: Improvements in drag bits
Inventor: BALL HARRY NORRIS
IPC: E21B10/567
Filed: 1982-10-18
Abstract: Disc-type diamond compacts (60), metallurgically bonded to a tungsten carbide insert stud (52), are interference fitted into holes (58) formed in a face of a drag bit (12). To inhibit a tendency to shear the tungsten carbide stud under side loads induced by the shearing action of the drag bit as it moves through a rock bit formation, as much of the tungsten carbide stud shank as possible is supported while allowing the diamond compacts cutting surface to penetrate the formation. In order to insert the stud deeper into the face (16) of a drag bit body, a portion of the face adjacent the diamond compacts cutter is relieved (as at 70) so that the bottom edge of the cutter does not contact the face of the body of the drag bit. The means (70) to relieve the drag bit face is a circular channel in the face of the drag bit body in front of the diamond cutting disc (60), the circumference of the channel (70) being slightly larger than the diamond cutting disc (60) for inserting the stud (52) supporting the diamond cutter deeper into the drag bit body (12). <IMAGE>

Title: Machine for Lasting Heel Seat and Side Portions of Shoes
Inventor: BRAMLEY FRANK
IPC: A43D25/18
Filed: 1983-04-29
Abstract: In a combined heel seat and side lasting machine two adhesive-applying nozzles (144) are provided which are movable along opposite sides of a shoe bottom from the backseam region thereof toewardly. For applying adhesive in the heel seat region, the nozzles (144) are each rotatable about an axis of rotation extending heightwise of the shoe bottom through a limited arc, the nozzles also being movable widthwise of the shoe bottom, independently of one another, and lengthwise of the shoe bottom in a common movement. In order to avoid problems arising from moving parts in the adhesive-applying system, each nozzle (144) has a melt chamber (142) associated therewith, and the nozzle and its associated melt chamber are mounted on a support (140) for pivotal movement about said heightwise axis as a unit. For facilitating the mounting of each nozzle and melt chamber, the axis of rotation (158) extends obliquely to the longitudinal centre line of the nozzle and associated melt chamber. <IMAGE>

Inventor: EBERL KLAUS
IPC: B60F3/00
Filed: 1984-01-24
Abstract: A wheel or axle assembly is retractable into a corresponding wheel box (2) in a vehicle body (1). The axle assembly (5, 6, 7) is guided by means of parallel track arms (6, 7). The raising and lowering is effected by means of a pivoted hydraulic piston and cylinder device (8, 9) whose piston rod (8) is articulatedly connected to one arm (11) of cranked lever (10) pivotable about a fixed pivot (13). The other arm (12) of the lever (10) is articulatedly connected to the axle assembly (5, 6, 7) via a spring strut with shock absorber (14). In the rod-travel position, the cranked lever (10) is pivoted to such an extent that its arm (12) slightly exceeds its bottom dead centre position, thus ensuring that this position is maintained even in the event of failure of the piston and cylinder device. <IMAGE>

Title: Roller guide for control of bark consumption in tapping of hevea brasiliensis
Inventor: SIVANAYAGAM S O SIVASAMBOO
IPC: B26B29/06
Filed: 1984-02-13
Abstract: This roller guide invention for control of bark consumption in tapping of Hevea Brasiliensis makes it possible for unskilled labour to perform the crucial tapping operation without causing unacceptable damage to the bark of the tree which is one of the major disadvantages of using unskilled labour for tapping with conventional tapping knives. The greater speed with which the trees can be tapped will enable the topper to tap more trees on a normal tapping day than would be possible with conventional tapping knives. The clearance between the roller guide and the cutter can be adjusted according to our own requirements by the adjustable plate.

Title: Sewing system
Inventor: OFF JOSEPH W A
IPC: D05B29/08
Filed: 1987-09-17
Abstract: A sewing machine has the cloth holding means 140 and the cloth clamping means as part of a X-Y-Z motion apparatus that is supported solely from the top arm of the sewing system frame. 
<??>Because the spaced twin needles of the sewing system will be required to penetrate up to 14 layers of thick cloth in some anticipated applications, considerable rigidity and stability is imparted to the single needle clamp that supports and reciprocates the two symmetrically spaced needle bars. This minimizes canting of the needle clamp and bending of the needle bar, thereby assuring more uniform stitch lines and minimizes missed stitches.
