Title: Wire matrix printing apparatus
IPC: B41J2/275
Filed: 1981-05-20
Abstract: In a wire matrix printing head a ring of wire-selection electromagnets are grouped about the wire guiding arrangement 17, the electromagnets each having a yoke assembly 3 with a pair of limbs each able to support a separate energising coil 5. The electromagnet armatures 14 are supported by a common frame 9 having a finger 10 for each armature, on which the armatures are respectively pivoted. The printing wires 22 are spring loaded into their restored positions and are there supported by an individually adjustable resilient backstop 31. The printing wires 22 are supported in guides so that they are arranged in two columns, both the columnar pitch and the pitch of nominally adjacent wires in the columns being of the order of the wire diameter. Control of wire selection from the two columns is arranged to prohibit a further selection of any one wire for printing unless the printing head has moved along the printing line for a distance equal to twice the columnar pitch. <IMAGE>
Patent GB-2075721-A (GB)
Title: Apparatus for determining sheet sizes
IPC: G03D3/06
Filed: 1979-09-20
Abstract: Apparatus for determining the size of a sheet having one of a plurality of determined sizes has a number of sensors less than the number of sheet widths, which sensors are arranged across the sheet location. From the length and width information determined by the sensors the size of the sheet can be identified using a catalogue of sheet sizes stored in a microprocessor memory. The microprocessor may then be used to control operations which are area dependent in a processing station or stations. One application is in the electrolytic removal of silver from a fixer bath in the processing of X-Ray films. Identification of the sheet sizes enables reliable estimation of the silver salts dissolved in the fixer from the films. This enables the electrolysis to be controlled so as to maintain the concentration of silver salts in the fixer at a suitable low level.

Patent GB-2086056-A (GB)
Title: Calibrations of capacitive fluid- gauging probes
IPC: G01F23/26
Filed: 1981-10-09
Abstract: Capacitive fuel-gauging probes 2 of the kind having an outer tubular electrode 20 are calibrated by means of a pump 70. The pump 70 pumps air into the interior of the outer electrode 20 until all the fluid in the probe 2 is forced out of its lower end 22, the electrical output of the probe being measured. The pump 70 is then switched, by a valve 74, to suck gas out of the probe 2 thereby raising the level of fuel within the outer electrode 20. When the fuel entirely covers the electrodes 20 and 23 the probe output is again measured. The two output valves are used in calibration of the probe 2. <IMAGE>

Title: Improvements in or relating to electrical contacts
IPC: H01R12/72
Filed: 1982-01-25
Abstract: An electrical contact for an electrical connector comprises an elongate electrically conductive strip consisting of two parts. The first part is resilient and is adapted to be used for making the contact, and this is joined (e.g. welded) to a rigid support part which holds the contact in the connector and is also used for making external electrical connections.

Patent GB-2099673-A (GB)
Title: Furrow inverter
IPC: A01B9/00
Filed: 1982-05-27
Abstract: A plough device 10 has at its front end a furrow-cutting assembly 39 which cuts and feeds a furrow slice into a rotatable drum 12. As the drum rotates, it moves the furrow slice around the rotation axis of the drum and causes it to slide along a non- rotating twisted blade 37 passing from end to end of the drum. The twist in blade 37 is such that by the time the furrow slice has reached the rear end of the drum it will have been inverted by the blade. It is discharged back into the furrow cut by assembly 39 in this inverted state by a downwardly tapering chute portion 50. <IMAGE>

Title: Mortar or other material flattening device
Inventor: CAPELL DAVID
IPC: E01C19/18
Filed: 1982-07-13
Abstract: A device (1) for flattening mortar or other suitable material for forming a bed for a slab comprises a body (2) that is rested on a previously-laid slab (9) so that by a brisk to and fro action a scraper plate 4 carried by the body flattens mortar or other suitable material roughly placed to one side of the slab (9). The placed material can thus be formed into a bed having a flat surface which can be seen to be free from bumps or hollows, and which is set at a correct height for receiving the next slab to be placed. This next slab is positioned and lightly tapped down, consolidating the material, and there is no need to lift the slab again to check the condition of the bed. <IMAGE>

Title: Fluid flow control system for an extensible jack
Inventor: FIELD JESSE L
IPC: F15B11/20
Filed: 1981-07-30
Abstract: Fluid flow control system (10, 210) for a multi-stage fluid operated jack (16, 216) which eliminates the problems of jack sequencing and speed control. The flow control system (10, 210) has a source of pressurized fluid (72, 74, 272, 274), a multi-stage fluid operated jack (16, 216), a sensor (79, 279) and a valve (62, 262). The sensor (79, 279) is actuatable in response to the jack (16, 216) being at a preselected elevated position to shift the valve (62, 262) and change the rate of flow delivered from the source (72, 74, 272, 274) to the jack (16, 216) from a first preselected maximum limited flow rate to a second preselected maximum limited flow rate. Therefore, the speed of extension and sequencing of the various stages of the jack can be automatically controlled. Thus, the fluid flow control system eliminates expensive and complicated jack construction, expensive and complicated valving and reduces the problems of speed control and jack missequencing. The fluid flow control system is particularly useful in a full free lift mast.

Title: Relieving stress in polymer articles
Inventor: FRISCH DAVID C
IPC: C23C18/16
Filed: 1983-05-17
Abstract: A method for rapidly relieving stress in an extruded or molded polymer article is disclosed. An article comprised of the polymer is exposed to electromagnetic radiation, for a time period sufficient to absorb enough energy to stress relieve the polymer against stress cracking therein. Exposure occurs at one or more ranges of frequencies capable of being absorbed by the polymer and effective for stress relieving without or substantially without causing heat induced deformation or softening and flowing of the polymer. The electromagnetic radiation is selected from infrared-, microwave- or ultraviolet-radiation. The method can be used in the manufacture of printed circuit boards.
