Patent GB-2060400-A (GB)
Title: Epidural end connector
IPC: A61M39/12
Filed: 1980-10-17
Abstract: A connector for a cannula or other fine bore tube has a central stretchable body 1 with a passage which is open at one end, 3, to receive a cannula and which is connected at the other end to a union 4 adapted to receive a syringe or other device. An intermediate rigid sleeve 7 surrounds the central gripper body 1. An outer rigid sleeve 10 is a sliding fit on the intermediate sleeve and can move between an extended position and a retracted position. The outer sleeve 10 is connected to the central stretchable gripper body 1 in such a way that it will stretch the gripper body when the outer sleeve has been moved to its extended position. This stretching will constrict the passage in the gripper body. Toggle arms 13 are provided for moving the outer sleeve to its extended position. Teeth 8 retain the outer sleeve 10 in its retracted position. <IMAGE>

Filed: 1980-12-09
Abstract: A gummer for a filter attachment machine comprises a roller (10) which combines with a further roller (12) [Figure 1] or blade to form a nip into which gum is supplied to form a pool.

Patent GB-2070399-A (GB)
Title: Real time toroidal pan
IPC: G09G5/14
Filed: 1981-02-24
Abstract: This video graphics raster display system allows panning over an image that is arbitrarily larger than the image memory from which the display is generated. To accomplish this, the image memory 105 is addressable toroidally, i.e., in modulo or wraparound fashion. Thus, if a memory address boundary is reached during a raster readout, the readout continues without interruption from the opposite boundary. The image memory 105 is slightly larger than would be required to store only the image currently being displayed on CRT 112. The excess memory area includes a border area, surrounding the current readout area, which contains image data that forms a continuation of the image currently being read out and displayed. This allows immediate panning into the border area. Further, the excess memory area includes a rewrite area outside the border zone into which new, image continuation data may be entered from host processor 128 while panning takes place. Appropriate circuitry 116, 121, 126 facilitates new data entry to the rewrite area and controls the panning rate to ensure that the displayed image will not reach the rewrite area until after the new data has been entered. <IMAGE>

Patent GB-2096404-A (GB)
Title: Waveguide junctions
IPC: H01P5/12
Filed: 1981-03-27
Abstract: An examination of equivalent circuits for various types of stripline junction shows that the presence of the abrupt discontinuity at the junction generates higher order TE modes additional to the desired TEM mode, thus causing the power to divide at the junction in a complex manner. Furthermore, it becomes clear that combinations of such junctions (as used in feeds for antenna arrays, for example) will suffer from systematic mismatch effects leading to significant amplitude and phase errors in the power division. A solution to this mismatch problem is to add "tuning" elements to the junction which provide extra mismatches which help to cancel the undesirable effect (of the reactive elements in the equivalent circuit), and the invention seeks such a "tuned" junction for a stripline in a particularly convenient, cheap and elegant manner. Thus, the invention provides a stripline junction between a main line (1,2) and a branch line (3) wherein in at least one of the downstream arms (3) of the junction there is one or more elongate apertures, or slots, across the width of the stripline, this slot (or group of slots) being positioned at a distance from the junction of an odd number of quarter wavelengths - 1 DIVIDED 2 (m + 1 DIVIDED 2)  lambda s (where m is zero or an integer, and  lambda s is the, or the mean, wavelength of the signal to be carried by the stripline). <IMAGE>

Title: Bird decoy
Inventor: TURNER ALFRED
IPC: A01M31/06
Filed: 1982-05-01
Abstract: A bird decoy comprises an artificial bird whose wings can be made to flap. The bird (11) is fixed to one end of a generally rectangular frame whose other end pivots about pegs (12, 13) driven into the ground. The frame holds the bird up in a standing attitude when the main side bars (16, 21) extend along the ground. The bird's wings (27, 29) are resiliently biased shut by elastic cords (26, 28) which run from each wing tip to a corner of the frame. A line (34) runs from one wing tip, out to and around an eye carried on an arm (24) projecting from the frame, the line comes back across the bird's body to and around another eye carried on another arm (25) and finally runs to the other wing tip. When the line (34) is pulled backwards at its mid-point, the wing tips (27, 29) will open about hinge lines (32, 33) against the resilience of the elastic cords (26, 28). If the line is pulled hard enough, the frame and hence the bird will rise from the ground about the pegs (12, 13). <IMAGE>

Title: Load handling vehicle with tiltable mast
Inventor: REEVES JERRY L
IPC: B66F17/00
Filed: 1982-12-17
Abstract: The operator of a lift truck or other load supporting vehicle (11) having a tiltable mast (12, 12a) is alerted as the mast (12, 12a) tilts beyond a predetermined orientation by a temporarily slowing of the rate of tilting movement. Return motion of the mast (12, 12a) may be unimpeded. The operator is reliably made aware when the mast (12, 12a) reaches a predetermined limit but may continue the tilting motion when that is necessary for such purposes as traveling the vehicle (11) under overhead obstruction. In systems where the mast (12, 12a) is tilted by fluid motors (20, 20a), the automatic tilt speed reduction may be realized with a valve (33, 33a) which temporarily introduces a one way flow restriction (49) into the fluid flow path (28, 28a) between the motors (20, 20a) and pressurized fluid source (27, 27a), the valve (33, 33a) being actuated by inclination sensing mechanism (23, 23a).

Patent GB-2116767-A (GB)
Title: Testing coins
Inventor: DEAN ROBERT
IPC: G07C3/00
Filed: 1983-02-11
Abstract: The operation of a coin testing apparatus is checked by switching the apparatus to a test mode. In the test mode, the properties of items inserted into the apparatus are compared with stored «test» ranges, instead of «acceptability» ranges which are normally used to determine whether the item is a genuine coin. A specially designed non-genuine coin is then inserted into the apparatus. If the measured properties of the non-genuine coin fall within the «test» ranges, a signal is produced to indicate that the apparatus is operating correctly. If any of the properties falls outside a «test» range, but within a further, contiguous range, a signal indicates that the apparatus is working adequately, but not optimally.
