Abstract: 1,265,404. Cutting webs. ARTOS DR. ING. MEIER-WINDHORST K.G. 4 June, 1969 [5 June, 1968], No. 28326/69. Heading B4B. A machine for cutting pile material, e.g. tufted material, along a line parallel to a tufted edge thereof comprises a sensing device having a pair of runners 27, 28 between which the material passes and arranged to contact a lateral edge of the pile, the runners being spring- urged together and mounted on a carriage 24 which is vertically adjustable in order to correspond with the height of the travel path of the material. The runner 27 is connected by a bracket 26 to the carriage 24 and the runner 28 connected to the latter by means of rods 30 and springs 29; the spacing between the runners can be adjusted by a screw device 42, 43 and they may be coated with P.T.F.E. to reduce friction. The carriage is slidable on a guide-bar 23 via bearings 25, which bar is mounted on a plate 22 vertically adjustable on a carriage 13 by means of a screw 16 and pin-and-slot devices 18, 19. Side edges of the runners 27, 28 are held in contact with the pile edge as shown in Fig. 1 by means of a cable 32 connected at one end to the carriage and at the other end to a weight 31; alternatively, the weight may be replaced by pneumatic or hydraulic means. The carriage 13 is adjustably mounted on an arm 11 by means of a rack-and-pinion device, the arm being laterally movable by drive means which also operates the cutting device; the cutting device is also mounted on the arm. In operation, the pile material is fed between the runners positioned, in the direction of feed, in front of the cutter. In the event of an irregularity in the pile edge the carriage 24 is moved so that a lug 37 thereon actuates one or other of proximity magnetic switches 35, 36 thereby causing the drive means to move the arm laterally, together with the cutter, until the particular switch is de-energized. Similarly, if the pile edge runs under the upper runner 28, the latter lifts against the action of the springs 29 until a rod 30 actuates a switch 38, this again causing the arm to move laterally until the normal position is reached.

Abstract: 1289729 Measuring osmotic fragility photoelectrically AMERICAN OPTICAL CORP 13 Nov 1969 [13 Nov 1968] 55655/69 Heading G1A Apparatus for testing the osmotic fragility of organic cells includes means arranged to monitor the response of a photo-cell receiving light transmitted by a test sample in a transparent curvette while diluting fluid is being fed into the sample. In the arrangement shown light from a lamp 14 passes through a lens 16, an iris diaphragm 34, a red filter 18 and a sample 10 (comprising blood cells in an isotonic suspension medium) and falls on a photo-resistor 20 controlling a pen recorder 28. After adjustment of the diaphragm to obtain a suitable starting point on the recorder operation of the apparatus is effected by manual actuation of a switch. A pump which has been circulating a diluting fluid such a distilled water from and to a storage vessel commences to discharge the diluting fluid into the sample at a constant rate via a tube 36, a stirrer 40 ensuring uniform mixing. As the concentration of the suspension medium drops the osmotic pressure in each cell builds up until the membrane of that cell bursts or opens its pores releasing haemoglobin into the suspension medium. During this haemolysis the cells become transparent and pass more light to the photocell. The red filter eliminates the colour changes in the suspension medium and a variable resistor (not shown) connected in parallel with the resistor 26 and continuously adjusted by a timer compensates for gradual changes in the transmissivity of the sample due to the addition of the diluting fluid. The shape of the curve drawn by the pen recorder can be analysed to give information in the health of a patient.

Abstract: 1295273 Windscreen washers CHRYSLER UNITED KINGDOM Ltd 17 Sept 1970 [19 Sept 1969] 46341/69 Addition to 1168631 Heading A4F [Also in Division H1] The windscreen washing device claimed in the parent Specification is modified so that movement of the operating member for actuating the pump to an intermediate position between the first and second positions closes the switch and return movement of the member to the first position opens the switch. When the pump actuating member 21 is depressed to a position in which a spigot 28 engages the end-plate 29 of the bellows 13 of the windscreen washer pump, a shoulder 45 on the member 21 engages an abutment 43 on an armature 31 of the wiper motor switch and rotates it through 90 degrees. The two spring contacts 37 of the switch are then engaged by one of two conductors 36 which extend along the armature and are exposed at opposite corners of each of two armature parts 34 of square cross-section, and the switch is closed. Further depression of the member 21 operates the bellows 13 of the pump, and if the member 21 is then released it is returned by a spring 26 to its initial position without rotating the armature 31 to open the switch. The latter is opened by again depressing the member 21 to rotate the armature through a further 90 degrees by the engagement of the shoulder 45 with a further abutment 41 on the armature. If the member 21 continues to be depressed to operate the washer pump bellows 13 a shoulder 46 Fig.2 (not shown) on the member 21 engages an abutment 43 to rotate the armature through a further 90 degrees to re-closed the switch. If the windscreen wiper is required to operate for a short duration without operation of the washer pump the member 21 is depressed only sufficiently to engage the shoulder 45 with an abutment 43 and rotate the armature 31 until the lower conductor 36 just touches contacts 37 without fully displacing the corners of the armature parts 34 from V-formations on the contacts 37. When the member 21 is then released the armature 31 is then returned to the open position by the detent action of the contacts 37.

Abstract: 1297121 Jointing by stamping; shearing; welding NOVOPRESS GmbH PRESSEN UND PRESSWERKZEUGE & CO KG 20 Nov 1969 [20 Nov 1968 11 Aug 1969] 56922/69 Headings B3Q, B3R and B3W Apparatus for crimping and cold-welding cable connectors, sleeves &c. to conductors, ropes or rods comprises two die-surfaces disposed at an angle to each other and a die adapted to be driven towards the die-surfaces by means operable to vary the length of the crimping stroke depending on the size of the workpiece and to stop the driven die. In one form, Fig. 1, there is a fixed die 6 and a die 11 movable along an inclined guide by a die 5 which is also carried laterally by the die 6. The press is stopped by contact between the crimped connector and a pivoted member 13 which operates a draw-rod 14 for opening a valve 16 against the force of a spring 15. Thus hydraulic fluid from a pump 18 to a cylinder 1 for operating the die 5 escapes to a reservoir. In another construction, Fig. 2, the pivoted member 13 carries an adjustable abutment 21 for operating an electric limit switch 30. A slide 29, 24, 25 carrying the member 14 is biased by spring 27 towards the sleeve 44 so that the switch is opened in the absence of a sleeve. Alternatively, the limit switch (10), Fig. 3 (not shown), of an electrically driven apparatus may be operated direct by contact with the connector, the driven die (5) being wider than the stationary dies (6). In another construction, Fig. 4, die 5 is mounted on a handle 1 to which is pivoted a lever 3 carrying the die 5. Also mounted on the pivot 30 is a strap 84 which is pivoted at 95 to a handle 89. A pin 90 on the handle is received in a slot 96 in the lever 3 and the members are held straight by a spring 91. As the resistance to movement of die 5 increases, the handle 89 turns about the pin 90, releasing a pawl 92 for engaging teeth 86 so as to lock the strap 84 to the handle 1. The handle 89 now turns about the pivot 95, rotating the lever 3 about pivot 80 as pin 90 slides in the slot 96. An hydraulic cylinder may be fitted for increasing pressure. Shearing; punching; gripping.-These operations may be performed by additional tools, e.g. the shearing tools 81, 83, Fig. 4.

Title: Pulse control of high-voltage rectifiers

Filed: 1971-01-27
Abstract: 1312762 Controlling rectifiers VSESOJUZNY ELEKTROTEKHNICHESKY INSTITUT IMENI VI LENINA 27 Jan 1971 3239/71 Heading H2F In a polyphase rectifier using controlled elements 5 (e.g. mercury arc or thyristors), the zero passage in the voltage across the rectifier elements is detected and used to control the generation of triggering pulses in such a way that, should the anode of a rectifier become reverse-biased during a conduction interval, a further firing pulse is produced when the anode again becomes forward-biased. This has the effect of preventing false operation due to transients in the anode voltage. As shown, an output pulse is produced by zero passage detector 6 when the anode voltage of the rectifier 5 passages through zero from negative to positive. This pulse is transmitted by an information link 7 using light or radio, to an AND gate 3, opened by a wide pulse generated by a synchronizer 2, the start of the wide pulse being set by a phase shifter 1, controlled by a regulating signal U. The AND gate 8 thus gives an output at the start of each wide pulse from synchronizer 2 if the anode of the appropriate rectifier is forward-biased. The pulses from AND gate 8 pass via a shaper 3 to a pulse distributer 4 which sends pulses to the appropriate triggers of the rectifier elements 5. If the rectifier should become reverse-biased by transients, a output from gate 8 is provided when the anode again becomes forward-biased so that retriggering is effected. In an alternative embodiment, the synchronizer may produce two pulses defining the beginning and end of the required conduction period and these may activate a bi-stable circuit 9 or a one-shot multivibrator. In Fig. 2 (not shown) the information link is inserted between units 2 and 9; units 3, 4, 6, 8, 9 being mounted on the rectifier platform. Fig. 5 (not shown) relates to a suitable transistor circuit.
