Title: Chronograph
IPC: G04G5/00
Filed: 1973-09-20
Abstract: 1412165 Electric chronographs SUWA SEIKOSHA KK 20 Sept 1973 [22 Sept 1972]  44145/73 Heading G3T In a chronograph having a quartz crystal oscillator 3 as a time base, the circuitry is so arranged that the same liquid crystal or solid state display 1 is used to show time of day when functioning as a timepiece or elapsed time as a stop-watch. As shown the display is energized via a de-coder-driver circuit 2 and indicates to tenths of a second in the stop-watch mode only. The oscillator 3 feeds respective divider circuits 4, 5 for the two modes, the appropriate divider being selected by a circuit 6 under the control of a switch 8. The switch 8 also controls a second selector circuit 7 so that switches 9, 10, 11, which respectively serve to set seconds, minutes, and hours in the timepiece mode, serve for reset, startstop, and lap time operations in the stop-watch mode.

Patent GB-1271039-A (GB)
Title: A character reader
Inventor: SAKAI KUNIO
IPC: G06V30/10
Filed: 1970-09-16
Abstract: 1,271,039. Character recognition. TOKYO SHIBAURA ELECTRIC CO. Ltd. 16 Sept., 1970 [16 Sept., 1969; 11 Dec., 1969], No. 44234/70. Heading G4R. In a character reader, suitability of the threshold used for quantizing the character scanner output is determined from the outputs of an average character stroke width calculating device and a character block number calculating device both fed from the quantizer. In the average character stroke width calculating device the quantizer output is fed to shift registers, successive 2Î2 bit patterns in which are each recognized by logic to increment one or none of three counters relating to respective categories of 2Î2 bit patterns, the final counts being weighted appropriately, summed, and the result divided into the number of black bits in the character as counted by another counter fed directly from the quantizer, the quotient being the average stroke width. The character block number calculating device calculates the number of disjoint areas of the quantized character by feeding the quantizer output to shift registers, logic responding to successive 2Î2 bit patterns at the entry ends of the register to detect the beginnings and ends of sections through loops as seen in the registers and to fill in the loops by inserting is into an auxiliary shift register between detection of such a beginning and such an end and, on detection of such an end, gating the contents of this auxiliary register in parallel into the first of the other registers. Further logic responds to the other ends of these latter registers to detect various 2Î2 bit patterns representing various changes in direction of the character outline. Pulses representing these changes increment a counter by +1, -1 or -2 as appropriate so, ignoring the two lowest order bits, the count finally represents the number of disjoint areas of the character (since for one disjoint area the boundary has to change direction by a total of 360 degrees). Other shift registers, logic and counter similarly indicate number of disjoint areas minus number of loops, by omission of the loop filling feature. The number of loops is then obtained by subtraction, and the number of disjoint areas, number of loops and the average stroke width are used to determine whether the threshold used in the digitizer was appropriate. If so, a store fed with the digitized character signals is gated to character recognition circuitry. If not, the threshold is adjusted up or down and scanning &c. are repeated. A second embodiment differs in having a plurality of quantizers with different fixed thresholds, feeding respective devices as above, the digitized character signals obtained from the threshold judged appropriate by the system being gated to the character recognition circuitry.

Title: Apparatus for and Method of Cooling Extruded Molten Filaments
IPC: D01D5/088
Filed: 1968-09-19
Abstract: 1,193,370. Quenching filaments. FMC CORP. 19 Sept., 1968 [4 Jan., 1968], No. 44629/68. Heading B5B. Quenching apparatus suitable for cooling molten synthetic polymer filaments extruded from a substantially circular spinneret assembly 18 (Fig. 2) comprises an enclosure 1 defined by end walls 2 and 3, side walls 4 and 4<SP>1</SP>, and a front wall comprising front side sections 6 and 6<SP>1</SP> and a longitudinal concave foraminous surface 7 extending into the enclosures. As shown, surface 7 is held in place by longitudinal strips 8 and 8<SP>1</SP> and concave strips 9 and 9<SP>1</SP>, and may be a wire screen, perforated sheet metal, a combination of both or any other air distributing foraminous surface. The curved perforated wall 11, mounted between the front wall and back wall of the enclosure, ensures a more even distribution of air or other gas from supply inlet tube 12, which extends from back wall 5 and is adapted for telescopic connection with tube 13, which extends into plenum chamber 14. Key 15, attached to the under side of tube 12, slidably engages slot 16 of tube 13. Orifices 17 in tube 13 facilitate gas flow into tube 12. In a modification, not shown, the gas inlet supply is connected to the bottom or back of the quenching apparatus, baffles serving to distribute the cooling gas. The quench device may also be mounted to slide up and down relative to the spinneret. The quenching apparatus is so designed as to be capable of being positioned as close up to the face of circular spinneret assembly 18 as possible, as shown in Fig. 2, in order to solidify the filaments more quickly. The semi-circular foraminous surface of the quenching apparatus produces a semi-radial horizontal flow of cooling gas across the filaments without a corresponding concurrent flow of the gaseous medium with the extruded filaments, thus obviating the type of turbulence encountered with cylindrical quenching apparatus, where the gas currents meet at the centre of the filament stream. In addition, access to the spinneret for cleaning and lacing is facilitated, and quenching results are found to be superior to those obtained using straight wall quenching. Quench gas velocities of about 9 to 30 metres per minute are used, the lower velocities being preferred for lower denier yarns, and the higher velocities for higher denier yarns. Examples illustrate the spinning of polyethylene terephthalate filaments.

Title: Improvements in or relating to detectors of gases, vapours or smoke
IPC: G01N27/66
Filed: 1964-11-05
Abstract: 1,088,836. Smoke detectors. ETABLISSEMENT POUR APPLICATIONS ELECTRONIQUES. Nov. 5, 1964 [Nov. 6, 1963], No. 45158/64. Heading G1N. A detector of gases, vapour or smoke comprises an ionization chamber containing a radioactive source forming one limb of a potential dividing network which is adjustable to vary the sensitivity of the device and also a capacitor variable to adjust the time constant. The radioactive source and the collector electrodes may be separately adjustable in the ionization chamber Fig. 3 (not shown) which may contain accelerating electrodes between the two. The potential dividing network is connected to the starter electrode of a cold cathode tube and provided, as shown, with an H. T. supply adjustable to vary the firing point of the system. The variable capacitor is connected between the starter electrode and the cathode. The striking of the tube may operate a relay. Two such systems may be arranged with their ionization chambers disposed to collect and respond to lighter-than-air and heavier-than-air components respectively, the two cold cathode tubes being connected to a relay in a common cathode circuit Fig. 5 (not shown). Alternatively the ionization chamber circuits can be connected to a single tube with separate starters Fig. 6 (not shown). As another alternative the common cathode circuit of two tubes may contain a resistance and the voltage developed across it may fire another cold cathode tube Fig. 7 (not shown). A number of such systems in different locations may be connected as a counter chain so that the number of impulses transmitted is a measure of which detector has fired. The potential dividing network which provides the starter potential may contain thermistors so that the system is sensitive to temperature changes also Fig. 8 (not shown). Alternatively the thermistors may form a separate network, the output from which is amplified by a transistor before application to the starter Fig. 9 (not shown). The temperature sensitive and ionization chamber networks may be connected to separate cold cathode tubes Fig.10 (not shown) but these in turn, may be coupled to a common tube Fig.11 (not shown). The common tube may be made to respond also to the amplified output from a photo-cell so that the system is light-sensitive also.

Title: Improvements in or relating to valveless blow-moulding machines
IPC: B29C48/09
Filed: 1965-10-26
Abstract: 1,113,340. Valveless multi-head extruder. DIAMOND ALKALI CO. 26 Oct., 1966 [28 Oct., 1964], No. 45296/65. Heading B5A. A valveless extrusion machine for blowmoulding may extrude material from several extrusion nozzles simultaneously. It comprises an extruder (not shown), an accumulator system (top right, Fig. 3) and a distribution system (plate 12) having a plurality of passageways (e.g. 17) connecting to multiple-head housings (Fig. 2 shows two twin-head housings), each extrusion head being provided with a mandrel so as to extrude a tubular parison. Material is extruded into passage (3d) of the accumulator system, past the ram (2), and into plate (12) of the distribution system at (16). The passageways of the distribution system are preferably descending, and the plate may be shaped so that the material enters in an upwardly-extending part and has a plurality of downwardly-extending parts, each enclosing a descending passageway. In the example shown in the drawings, the plate (12) has the shape of an inverted Y (Fig. 1, not shown). The material is divided into these descending passageways (17, 18), and passed into the horizontal passageways (36, 37), to the housings (32, 33). These passageways are preferably straight, and connected by faired surfaces. They should preferably be internally lubricated. As seen in Fig. 2, the two streams are then split further and deflected into passageways (46), (47), (48), (49) to the extrusion heads. The mandrels (Figs. 4, 5, not shown) have lateral surfaces (84) cut away so as to deflect the material downwards. The deflecting surfaces (85) may be curved and encircle the lateral surfaces of the mandrels. The material passes over the mandrels and is extruded as tubular parisons from the orifice (82). A preferred mandrel design (Figs. 6-8, not shown) has shallow channels to direct the material, formed by upper deflecting surface (94) and lower surface (96) of an island (90) not cutaway. The island terminates at the bottom of the mandrel in a point (99), the upper surface terminating, also at the bottom of the mandrel, at a point (98), so that the channels each occupy 180 degrees of the surface (see Fig. 8, not shown). There may be further passageways in the extrusion heads for the introduction (at 57, Fig. 3) of cooling fluid e.g. air, which passes through tube (54) and escapes through vents (80), annular recess (79), chamber (81) and openings (not shown) in housing (32) and mandrel (50). A heating system (81a) preferably thermostatic may be accommodated in a further passageway (in this case, chamber 81) and may be co-ordinated with the coolant controls. The parisons may be blow-moulded by air supplied through central tube (73) and nozzle (77a).

The upper portion of the piston-rod is provided with fluid conduits which open into the chamber 144 and a pair of conduits 74 which open into a balancing chamber 68 as well as the chamber 146. The chamber 68 is formed by a stepped portion of the upper part of the piston-rod engaging in a cup-shaped formation 66 on the lower portion of the piston-rod and the annular area 150, Fig. 10, is equal to the area 148 thereby balancing the load on the lower pistonrod portion 64 so that the continuous hydraulic pressure in the chamber 144 urges a tubular section 70 of the piston-rod against a retaining nut 72. When the chamber 144 is at operating pressure an upper and collar 100 of the cylinder is forced upwardly against a retention member 116 thereby locking the cylinder assembly to the ram. The upper and lower end collars 100, 102 are held loosely to a sleeve 98 of the cylinder 96 by tie rods 108 which are inoperative when the ram-cylinder assembly is hydraulically locked.

Abstract: 1362801 Multi-disc brakes; discs DUNLOP Ltd 29 Sept 1972 [7 Oct 1971] 46582/71 Heading F2E An aircraft braking system includes a stack of interleaved rotor and stator discs co-operating pairs of which are both carbon based and non- carbon based friction pairs. Fig. 1 shows a single unit having rotors 1, 2 and stators 3, 4, 5: the rotors 1, 2 are slidably keyed to a rotatable portion of the aircraft wheel and stators 3, 4, 5 are slidably keyed to a non- rotatable portion of the wheel support structure and the brake is actuated by a series of circumferentially spaced hydraulic cylinders 14 in a support 15. As shown, rotor 1 and stator 3 have iron based friction facings 6, 7, 12, rotor 2 and stator 5 have carbon based friction facings 8, 9, 13 whilst the central stator 4 has an iron based facing 10 to engage iron based rotor facing 7 and a carbon based facing 11 to engage carbon based rotor facing 8. The carbon based materials are for example, mixtures of moulded carbon and graphite crystalline structures, or pure carbon or graphite or graphite fibres in a carbon or graphite matrix: the non-carbon based material can have a minor proportion of carbon or graphite but consists mainly of sintered mixtures of metal and ceramics, for example an iron-based material may consist, by volume, of approximately 70% iron and 30% ceramic; other non-carbon based friction material such as bronze or ceramic based materials may be used in place of or in addition to the iron based material. The friction facings are conveniently applied to the rotors and stators as a series of circumferentially spaced pads. In Figure 2 (not shown) iron based pads are mounted in dove-tailed recesses in each side of a rotor or stator backing member which is sandwiched between the pads, but in Fig. 3 (not shown) the pads extend right through the rotor or stator. Fig. 4 shows a suitable method of mounting carbon based friction pads 30 on one side of a rotor or stator 31 and iron based pads 32 on the other side: the carbon pads 30 have protrusions 33 located in recesses 34 in the iron based pads 32. Fig. 5 illustrates an alternative construction in which the outer portion 35 of each pad 36 is made from an iron based material and the inner portion 37 is made from carbon based material with gaps 38, and the two portions in use will engage corresponding portions on an adjacent friction member of the same material. The aircraft braking system may have units as described above or alternatively half of the brake unit may comprise carbon-based friction pairs only, and the other half non-carbon based friction pairs only.
