Patent GB-1361057-A (GB)
Title: Location digitizer
IPC: G06F3/033
Filed: 1971-07-19
Abstract: 1361057 Co-ordinate location digitizer SCIENCE ACCESSORIES CORP 19 July 1971 [21 July 1970] 33715/71 Heading G4H In a graphical data device the position of a stylus 132 on a two-dimensional wire grid 26 is recorded in X, Y counters as the time difference between an initial pulse 30A from a stylus triggering device 134 and the centre of a pulse 30B induced by the stylus in the wires nearest to it and fed through X, Y delay lines 28 and 30. Fig. 3 shows explicitly the apparatus for digitizing the X-co-ordinate: counters 112-116 and 120-128 are duplicated for the Y-co-ordinate (represented symbolically as Y-PCF and CY). Pulse 30A is fed along an input line 122 (as stylus 132 is triggered) to J-K flip-flop circuits 124-128. Initially the flip-flops are reset by a pulse (Q=O throughout) so as to inhibit andgates 114 and 120; appearance of pulse 30A at input C of 124 causes it to revert to a 1-state so that gate 114 is enabled and pulses of frequency F can pass into counter 112 from a pulse generator 110. Appearance of pulse 30B on line 122 leaves 124 unaffected but causes 126 to revert to a 1-state: this inhibits gate 114 and enables gate 120 so that pulses now reach the counter 112 via a pulse divider 118 at a frequency ¢F. The disappearance of pulse 30B on line 122 inhibits gate 120 and the pulses are cut off altogether; further pulses (from wires in the grid other than the closest) have no effect until 124- 8 are reset since such a pulse would set 128 and inhibit gate 120. The above process effectively measures the "distance" between the leading edge of pulse 30A and the centre of pulse 30B; an and-gate 164 permits connection of counter 112 (via a read-out unit 162) to a computer channel 166 or to a D/A converter 168 and a cathode-ray screen 170. Pulse 30A may be energized by a one-shot or a free-running trigger 136, 138 or by a computer control 140. A pulse in a coil in the tip of stylus 132 induces pulses in the wires of the grid 26 which travel to the delay lines 28, 30 (Fig. 1, not shown). A pressure switch 145 in the stylus may be provided to control both pulse generation and readout.

Title: Improvements in or relating to the concentration, distillation or evaporation of liquid substances
IPC: B01D1/28
Filed: 1933-12-01
Abstract: In evaporating liquids by a heating medium having a temperature only slightly higher than that of the liquid to be evaporated, the evaporating surfaces enclosing the heating medium are disposed partly or wholly above the level of the liquid and the liquid is caused to form a froth on the evaporating surfaces.  Frothing may be produced by concentration of froth producing substances contained in the liquid or by adding frothing-agents, e.g. alkaline carbonates.

Inventor: MACCABE DOUGLAS ARTHUR
IPC: B62J7/02
Filed: 1953-12-05
Abstract: 772,428. Luggage-carriers. BIRMINGHAM SMALL ARMS CO., Ltd. March 7, 1955 [Dec. 5, 1953], No. 33883/53. Class 136(1). A parcel carrier for a cycle consists of a onepiece bifurcated support frame 1 made from tubing which is flattened at its free ends 3. Holes 5 are formed in the ends 3 for the reception of a clamping bolt which also passes through rearwardly extending lugs 13 formed on the steering head 9 of the cycle. An arcuate cross member 7 is welded between the arms of the frame 1 near the ends 3 and is adapted to engage the front surface of the cycle steering head. When in position on the cycle there is a portion of the carrier frame which slopes downwardly very steeply. The frame then extends horizontally to form the actual support for the parcels. A tubular cross member 11 is secured to the two arms of the frame 1 where the frame becomes horizontal. Specifications 444,909 and 772,429 are referred to.

Abstract: 857,489. Filing documents. OZALID CO. Ltd. Feb. 28, 1957 [Nov. 28, 1955 : July 18, 1956], Nos. 34091/55 and 22240/56. Class 146(1). A document container comprises one or more compartments defined by a front and a back wall or partition each having a non-linear profile in horizontal section over at least a major portion of the height thereof, the fixed or removable walls or partitions occupying positions at fixed separations from each other in use, and a bottom wall at substantially right angles to the front and back walls, the walls containing documents to a curved configuration to confer rigidity thereto against buckling or folding under their own weight. As shown in Fig. 8, a number of similar compartments 13 are inserted in a container 6 with V-shaped front and back walls 11, 12 to take the V-shaped front and back walls 1, 2 of the compartments 13. Each compartment may be used as a separate container. Curved walls 1, 2 may be used instead of V-shape. As shown in Fig. 7, a cabinet 6 has side walls 3 formed with grooves 9 to take curved partitions 10 which may be fixed or removable. As shown in Fig. 9, to facilitate entry of the documents, the mouth of the container is substantially straight and the sides 1, 2 of increasing curvature down to the base 4. A similar arrangement of curvature is used in Fig. 13 where the partitions are formed by spaced parallel slats, rods or wires extending between top bars 15 and the base 4 where they lie on a curve 16. To prevent the side edges of drawings projecting between adjacent rods 14 into the next compartment sheets 17 are used for the sides of the partitions. The base of a container may be sloped, with the bottoms of the containers still at right angles to the walls 1, 2, so that documents tend to lie against one wall. Lids may be provided, to be fitted over the containers or hinged thereto.

[Class 78 (i)] An aligning means for a conveyer belt comprises a roller unit pivotally mounted on a frame, a lever arm secured to the roller unit for turning it upon its pivot, upright shafts on opposite sides of the belt and journalled in said frame, rollers secured on said shafts at the level of the side edges of the belt and adapted to be engaged, by said side edges when the belt shifts laterally on its roller unit and means operably connecting said shafts to the lever arm to turn the roller unit about its pivot upon engagement of the belt with either of said rollers. The idler rollers 6, 7 and 8, Fig. 1, are supported by standards 9, 10, 11 and 12 on a cross-beam 13 which is pivotally mounted at 14 to the conveyer frame. This latter has uprights 16, 17 carrying bearings 23, 24 and 25, 26 for shafts 21, 22 to which are secured rollers 27, 28.

At the end of the forward movement the rear wall 6 abuts the front rail 12 of the chair and the seat 11 drops into rabbets 3 on the member 1 so that its seating surface (not shown), becomes flush with the top surface of the member 1. Catch means may be provided for adjusting the inclination of the back 9 when in bed formation.
