Title: Device for manufacturing a hollow article of plastic material
IPC: B29C49/48
Filed: 1970-10-20
Abstract: 1310396 Cutting waste during blow-moulding SIDEL 20 Oct 1970 [24 Oct 1969] 49776/70 Heading B5A A wall portion of a hollow article is removed during blow-moulding by providing a cutting edge projecting into the mould cavity and increasing the volume of that part of the cavity corresponding to the wall portion to be removed so that the blowing pressure cuts the article against the cutting edge. As shown in Fig. 3, an article 5 is formed by blow-moulding an extruded tube against the walls of mould halves 1, 2 and against cutting edges 6e, 7e by air supplied from blowing head 17. The mould halves have recesses 8, 9 containing slidable members 6, 7 held in their forward position against the blowing pressure by cylinders 11, 12 and by stops 13 against the ends of further recesses 14. After blowing to the shape of Fig. 3, the pressure in cylinders 11, 12 is reduced so that members 6, 7 are pushed back by the blowing pressure, slicing off the waste portion 5b and communicating recesses 8, 9 with the atmosphere via ducts 15, 16. The members 6, 7 may contain ducts 28, 29 for circulation of cooling- water.

Title: Laser optical range finders
IPC: G01S17/87
Filed: 1971-10-27
Abstract: 1373237 Photo-electric distance measuring SIEMENS AG 27 Oct 1971 [29 Oct 1970] 49837/71 Heading H4D  An optical range finder LG is coupled to a television set ZG, the range-finder determining which object MO1, MO2, MO3 is displayed on screen BS. The range finder emits from laser S1 light pulses of one radiation frequency and the echo signals are received by E1, the corresponding range being fed to indicator EA and output SA to other circuitry if desired. The ranges are also fed in succession to element EE which controls a target distance selector ZA. Selector ZA activates the receiver E2 after a predetermined period timed from emitting a pulse of a second radiation frequency from object illuminating laser S2 and also determines how long the receiver E2 remains active. Selector ZA therefore determines which of the echo signals from the objects are received and hence which image is displayed on the screen. The images are therefore displayed in succession and coincident with their corresponding range indicated at EA. The television may then be locked on to a particular range and hence target object. In a further embodiment a single laser may be used the two pulse trains of different radiation frequency being provided in succession by an optical frequency changer. Alternatively, a beam splitter may be used with an optical frequency changer in the path of one beam. A further possibility envisaged is a single laser transmitter emitting pulses of radiation of two different wavelengths. The television can be provided with a variable aperture angle which is preferably automatically varied in relation to the range of a selected target object.

Abstract: 1280939 Optical recording INTERNATIONAL BUSINESS MACHINES CORP 21 Oct 1970 [5 Nov 1969] 49920/70 Heading G4A Stored information is optically displayed to permit detection of error and correction before optical recording. A computer memory supplies the information to be recorded and recording control signals. The information is displayed on a CRT. Under operator control or after a predetermined delay, the information is recorded on photosensitive emulsion on a tape, giving the operator the opportunity to correct the information in the computer memory via interrupt and using a light pen or keyboard before recording. For the recording, a linearly polarized laser beam is modulated with the information electrooptically, then electro-optically deflected to the required recording position. Part of the recording beam is selectively passed to one or more light detectors to permit detection of position errors, light source failure or deflection circuit failure, any of which events also causes interrupt and restart of recording (of the same information this time) at a new frame on the tape. Holographic recording may be used, or recording as the presence or absence of spots.

Patent GB-508918-A (GB)
Abstract: 508,918. Calculating - apparatus. WANDERER - WERKE AKT. - GES. Aug. 25, 1938, No. 25037. Convention date, Aug. 28, 1937. [Class 106 (i)] In an accounting-machine having a travelling paper carriage 24, a balance totalizer 16 from which positive and negative totals can be taken, and a number of accumulators 17 and 18, individual ones of which are automatically selected in dependence on the column position of the paper carriage to take totals from the balance totalizer, a control is provided automatically influenced in accordance with the sign of the contents of the balance totalizer, which, when the paper carriage is in a predetermined column position, automatically selects a different accumulator when the balance total is negative from that selected when the total is positive. The general construction of the machine corresponds substantially with that described in Specifications 462,331 and 463,512. The driving shaft I of the machine operates racks 3 and 19 with which the various accumulators may be engaged by cams 146, 68, and 69. The cams 68 and 69 are mounted on shafts 64, and 65 operated by levers 53 any one of which may be depressed into engagement with a driving stirrup 56 by cams 39 on the paper carriage operating through link 42 and 47 or this control may be overridden by key operated links 136. The stirrup 56 is moved by a link 84 operated by a slider 88. The latter, as described in the Specifications referred to above is moved by a cam 99 on the driving shaft 1 co-operated with pawls 93, 94 and 95 controlled by keys for total taking, sub-total taking and non-addition processes. A similar slider and connection are used to operate the cam 146 for the balance totalizer. The latter is provided with two wheels each driven by a tens transfer device from the highest order wheel of one of the balance counters. Movement of one of these wheels indicates a change of sign of its counter and a pawl is operated connected by a linkage to an axle 369. A lever 373 thereon will then move a bell crank lever 402 which engages with either a lever 219 or 411. The lever 402 is operated through lever 404 from a cam on the paper carriage when a total is to be taken. Levers 219 and 411 each operate one of the levers 47 which each put a particular accumulator into operation. The shaft 369 in addition to effecting the automatic selection of accumulators in accordance with the invention also operates an indicating arm 379 which visibly displays the sign of the totals in the balance totalizer.

Title: Battery changers with means for preventing overcharging of the battery
IPC: H01M10/44
Filed: 1973-11-06
Abstract: 1445998 Battery charging systems SONY CORP 6 Nov 1973 [20 Nov 1972] 51386/73 Heading H2H A battery charging circuit comprises a voltage source 3, a thyristor 2 connected in series with the battery 1 across the source, a reference potential source and a comparator circuit 13 for maintaining the thyristor non-conductive when the open circuit battery voltage reaches the reference potential. The source 3 supplies a pulsating voltage to the battery and the thyristor 2 is non-conductive at the instant this voltage is zero. The voltage at a point P at this instant is therefore the open circuit voltage of the battery 1 which is compared with the reference potential determined by a potentiometer 15a in a Schmitt trigger circuit including transistors Q2, Q3. At the instant the open circuit battery voltage reaches the reference potential, the transistor Q2 conducts thereby rendering the transistor Q3 non-conductive. The output pulse from the Schmitt trigger is differentiated by a circuit 18 and enables a multivibrator 14 to switch on a transistor Q1. The thyristor 2 is therefore switched off to prevent over charging of the battery.

Abstract: 1,120,194. Pattern recognition. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd 3 Dec., 1965 [4 Dec., 1964; 21 June, 1965 (2); 4 Nov., 1965], No. 51452/65. Heading G4R. In a pattern-scanner, an electrical image of a pattern is produced, and converted to a sequence of electrical signals by an electron beam, a circular-type movement being imposed on an electron beam to cause it to follow the pattern or its image. In the main embodiment, a raster is imposed on a flying-spot scanner 1, 2, 4, 5 and an electrostatic storage tube 8 of the capacity-discharge type to transcribe a pattern on a document 3 to the storage tube 8. A coarser " searching" raster is then imposed on the storage tube 8 by a "searching" generator 18 until a part of the stored pattern is encountered 14 when the " searching " deflection voltages are prevented 19, 19<SP>1</SP> from increasing further, remaining stored on capacitors 17, 17<SP>1</SP> to provide part of the deflection voltages in the subsequent line following (tracking). Another part is provided by a sine voltage now amplified 23 from zero and a cosine voltage derived 24 from it, so that the beam in the storage tube 8 moves spirally from the end of the line until it crosses the full thickness of the line after which a delay circuit 26 opens a gate 27 to pass the signal from the storage plate 9 of the storage tube 8 to a direction detector 21. In response to each crossing of the line by the beam, this produces (21-4) a standard width pulse (D) which gates (21-5, 21-5<SP>1</SP>) the sine voltage and a cosine voltage derived (21-7) from it to integrators 22, 22<SP>1</SP> which increment the deflection voltages to step the centre of the circle now described by the beam, along the line. The direction detector 21 incorporates a delay and phase-shifter (21-3, 21-6) so that the stepping occurs 180 degrees around the circle from where the line-crossing actuating the stepping occurred. As the beam crosses the line it erases it. Absence of any signal from the storage plate 9 indicates the end of the line and causes application of the " searching " raster again (starting from the point of first detection of the first line or from the start) to detect any further (disjoint) line in the pattern and so on. During following of a line, the beam may be caused to wobble to allow a bigger " step " along the line while retaining adequate erasure. It is mentioned that signals from the line following may be fed to pattern recognition means but this is not described. A vidicon may replace the scanner and storage tube. Another modification uses the flying spot scanner to provide the recognition signals, the storage tube being used to eliminate signals from lines " followed " before. A variant on this modification is to replace the storage tube with one of the controlled grid type and use it to store images of those parts of the pattern so far followed.
