Patent GB-829330-A (GB)
Title: Apparatus for and method of counting the filaments in multi-filament yarns
Inventor: MORRIS WILLIAM JOHN
IPC: G01N33/36
Filed: 1957-04-30
Abstract: 829,330. Counting filaments in multifilament yarns. BRITISH RAYON RESEARCH ASSOCIATION. April 17, 1958 [April 30, 1957], No. 13661/57. Class 120(3) [Also in Group XIX] The invention relates to apparatus for counting automatically the number of filaments in a multifilament yarn. As described, the number of filaments in a multifilament yarn is counted in an operation effected by rocking a handle 13 first in a clockwise direction (Fig. 1) and then in an anti-clockwise direction. The handle 13 is fixed to a shaft 12 bearing cams 25, 26, the cam 25, when the shaft 12 is rotated clockwise to its fullest extent, causing a retracting plunger 46 to move a link 44 and cutter arm 41 to the right to the position shown, a cam 57, Fig. 3, raising the arm 41 vertically. Simultaneously, the cams 25, 26 act on the heads 35, 36 of spring-biased plungers 23, 24 thereby causing heads 29, 30 to move to the left (Fig. 2) enabling the ends of the length of yarn 65 to be engaged by clamps 19, 20 in the gap between the heads 29, 30 and fixed sleeves 27, 28, the centre part of the length being ribboned to separate the filaments by moving it across ribboning edges 17, 18 of plates 15, 16, the filaments then being positioned as shown in Fig. 5 relative to an armature 60 connected to a transducer 59. The handle 13 is now rotated anti-clockwise until the striker 39 engages an abutment (not shown), during which rotation the cams 25, 26 move so that the plungers 23, 24 are spring urged to the right thereby firmly clamping the yarn ends. The striker 39 co-operates with a sloped cam face 38 to rock a displaceable block 21 which carries the clamp 20 away from the clamp 19  which is carried by a fixed block 14, thereby tensioning the yarn. Simultaneously, the plunger 46 retracts to allow a spring 48 to urge the cutter arm 41 to the left so that its cutter blade 42 is disposed above the ribboned yarn 65 and the cam 57 lowers the arm 41 until it rests on the piston 49 of a dash-pot. A cam 64 on the shaft 12 operates a micro-switch (not shown) to close a circuit to a counter (not shown). The action of a spring 58 overcomes the effect of the dash-pot so that the arm 41 slowly descends and the cutter blade 42 sequentially severs the threads of the yarn 65, each such severance effecting a change in tension which is sensed by the transducer armature 60 and causes a pulse to be transmitted to the counter. When the yarn is completely severed, the handle 13 is moved back, the switch 64 is opened to zeroize and then isolate the counter by means not described, and the apparatus is ready for a further counting operation.
Patent GB-323704-A (GB)
Title: Improvements in or relating to matrix setting and type-line casting machines
IPC: B41B7/18
Filed: 1929-05-02
Abstract: 323,704. Wade, H., (Typograph Ges.). May 2, 1929. Clamping, aligning, and justifying matrices.- In order to enable ring-spacers to be used in machines in which the matrices and spacers are guided in a cycle on wires, and in which the line is moved to and from the casting position by a carriage, the square spindles, on which the spacers are mounted, are so arranged that they can be withdrawn from the spacer-rings. At the casting point, the line of matrices 1, Fig. 2, is locked between a stationary adjustable jaw 4 and a movable jaw 3, carried by a rotatable and slidable spindle 8. To the spindle 8 is connected a sliding plate 17, Fig. 6, which is adapted to cause. rotation of a spindle 22 carrying arms 20, 23, in which are formed bearings for the ends of the square spindles 25, Fig. 2, that carry the spacer-rings. After the line has been composed, the spindle 8 is moved endwise either by hand or automatically, whereby the arms 20, 23 are turned into position to receive the ends of the spindles 25. A pin 12 on the spindle 8 simultaneously slides in an inclined slot 14 in a fixed plate 13, whereby the spindle is rotated to raise the jaw 3 in front of the line. A pawl 27 catches the pin 12, and locks the spindle in position. The pin 12, in its movement, acts through an arm 28 on a slide 29 to release a rod 32, which is thereupon pulled down by a spring and starts the casting-mechanism. After the casting, the parts are restored to initial position by the action of the shaft 36, Fig. 6, of the mould-support, a projection on which lifts the rod 32. The pawl 27 is thereby raised, and the spindle 8 is returned to normal position by a spring 26. The square spindles 25 are inserted into, and withdrawn from, the spacer-rings by a sleeve 47, Fig. 2, sliding on a rod 48, and operated by a lever 46 from a sliding rod 40, Fig. 4, which is actuated by one of the machine cams. The lever 46 also operates a sliding bar 61, Fig. 4, having a bevelled end, which effects rotation of the rocking bar 58, Figs. 4 and 5, that serves to straighten and level the matrices. The movement of the rod 40 also permits the descent of a plate 52, Fig. 4, and causes levers 54 to fall behind lugs 62 on the rocking bar 58 and lock the bar in position. The rod 40 may be turned out of action, to enable the same line to be cast repeatedly.

Filed: 1951-06-11
Abstract: 684,587. Photographically duplicating sound records. LOEWE OPTA AKT.-GES. June 11, 1951 [June 12, 1950], No. 13756/51. Drawings to Specification. Class 98 (ii). [Also in Group XXXVIII] A method. and apparatus for making and copying records of electrical sound currents, comprises the employment of a rotating cylinder which is displaced axially by a lead-screw with reference to a recording device whereby a spiral record is impressed on said cylinder, and one or more copying tapes are unrolled by, and in contact with, the cylinder, whereby the record track being made is immediately transferred to the copying tape or tapes. In an alternative embodiment the lead screw is replaced by a keyed shaft along which the cylinder is drawn by cords passing over pulleys. The sound track on the cylinder may be in the form of a groove cut by a stylus, and the copying effected by inking the cylinder and printing the sound track on to the tapes for optical reproduction. In another method of recording, an electric charge picture is formed on medium consisting of a semi-conductor, such as selenium, or, eventually, of a non-conductor or of a conductor with mosaic sub-division which is arranged as a coating on the cylinder, the recording member consisting of an electronic valve with controlled electronic beam which influences the recording layer, through a Lenard aperture. The electric charge picture may be made visible by colouring matter contact copies obtained on a photographic tape by employing a light source inside the cylinder, which must in this case have a transparent wall.

Title: Improvements in or relating to couplings for pneumatic tyre valves
IPC: B60S5/04
Filed: 1939-05-09
Abstract: 528,495. Coupling-actuated valves. TURNER, H., and BROWN, T. May 9, 1939, No. 13788. [Class 135] A coupling for pneumatic tyre valves for the attachment of a pressure gauge or inflating connection and of the kind having two check valves symmetrical about a common axis or parallel axes has the two valve members so interlocked or interconnected that their separation beyond a predetermined amount at which they both connect simultaneously engage their seats causes a non-axial movement of one or both valve members. In the form shown in Fig. 2 each valve member is formed with a recessed flange 17 adapted to co-operate with a rubber washer 14 clamped by a ferrule 15 in a recessed part at the end of a tubular housing coupled to a pressure gauge by a branch 13. The valve members have a limited amount of play in the tubular housing and have locating spigots engaging the seat apertures and each have a flattened side to provide a fluid passage. Inclined surfaces 22, in projections provided on the back of each valve co-operate to tilt one or both valve members when they separate so that it is impossible for the two valves to be sealed simultaneously. A spring may encircle the overlapping interlocking projections. In a modification the two valves are coupled by'a link pivoted to each at a point off its axis.

Title: Improvements relating to switches in portable electric appliances
IPC: H01H3/50
Filed: 1950-06-02
Abstract: 669,237. Automatic circuit-breakers. HOOVER, Ltd. June 2, 1950. [June 14, 1949] No. 13863/50. Class 38 (v). [Also in Group XXIII] The motor of a portable powerdriven appliance such as a floor polisher is controlled by a switch which is moved "on" by depression of a pedal 13 and is then held "on" against the action of a return spring by the attraction of the field magnet 35 of the motor for an armature 36 so that failure of current causes automatic return to the "off" position. The switch may also be moved "off" by a second depression of the pedal. The switch, Fig. 3, is of the kind in which successive depressions of a button 26 move a pivoted member 27 alternately right and left, thereby operating the contact member alternately "on" and "off" through a dead-centre spring mechanism. In the form shown the button 26 is operated by a bar 19 on the pedal operated member 13 pivoted at 15. The member 27 passes through a hole in a slide 40 urged to the left, i.e. to the "off" position by a spring 42. Operation of the switch "on" therefore by the pedal 13 causes the slide 40 to move to the right and this operates a bell crank lever 38 so as to allow the armature 36 pivoted at 37 to engage and be held by the magnet 35. In a modification, Fig. 6, the left hand position of the slide 40<SP>1</SP> corresponds to the "on" position, and the pedal 13<SP>1</SP> operates a rectilinearly-moving slide 53 which engages the button 26<SP>1</SP> of the switch and also by means of a cam surface 65 rotates a plate 60 pivoted at 61, the plate in turn actuating a member 56 pivoted at 57 and thereby bringing the armature 36<SP>1</SP> up to the magnet 35<SP>1</SP> where it is held. The above movement of the plate 60 allows the switch to close, such movement otherwise being prevented by the interengagement of catches 62, 63 on members 60, 40<SP>1</SP> respectively. In this modification, operation of the pedal 13<SP>1</SP> to open the switch does so without pulling the armature away from the magnet.

Abstract: 763,598. Centralized dictation systems. SHORTER, F. W. T. May 19, 1954 [May 19, 1953], No. 14032/53. Class 40 (4). In a system wherein remote stations which are electrically connected to the central apparatus through relays controlled by switches from the stations are enabled to make, and play-back recordings, a selector mechanism is locked against operation from other stations when one station is actively connected to the recording apparatus and play-back to a user is limited to his own recording. Operation of the " Unit on " button, Fig. 2, operates relay 11 to drive the selector motor by increasing the voltage supplied thereto from transformer t, to the position allotted to the user where relay 10 is energized to release relay 11. The open contacts of relay 10 in the circuit of relay 11 provide the lock-out facility and lamp a indicates to the user that he has control. Power is conveyed to the user station over line B 1 and is applied to control master relays 1, 2 and 3 to record, rewind, and play, by the appropriate mechanically locking push-button. The operation of a push-button releases any previously locked button. Rewinding over lead F4 is prevented when a user first takes control since the operation of the rewind button would energize relay 9 over the mechanically-operated contacts 13a to open the circuit of the rewind relay 2. Mechanical contacts 13a are closed when the timing device is reset by the previous user. Open contacts 13b, also on the timing device, prevent the playing back of existing recording on the tape. Operation of the " record " button energizes relay 1 and switches the amplifier for use in the required direction, relay 1 operating relay 5 to drive the motor in the desired direction. Interlocking contacts on relay 1 prevent simultaneous actuation of the other master relays and relay 5 energizes various mechanical circuits, i.e. the brake lifting solenoid on the dictaphone apparatus. Transcribing stations described with reference to Fig. 3 (not shown) have unlimited winding facilities in both directions and may read all recordings. Fast forward running is provided by an additional button. Specification 744,259, [Group XXXVIII], is referred to.

Abstract: 572,583. Safety razors. HEIDE, H. C. (Gillette Safety Razor Co.) Aug. 27, 1943; No. 14039. [Class 30] In a safety razor in which the blade is provided with a longtudinal slot open at one end so that the blade may. be inserted by endwise movement, a spring plate 6, Fig. 2 is secured to the guard 2 to form a blade guide which exerts a gripping action on the blade 16 as it is inserted. The cap 4 is moved to and from clamping position by a nut rotatably mounted in the lower end of the hollow shank 1 and threaded on to the end of the solid shank 8. The insertion and removal of the blades is preferably effected by the aid of a blade magazine which is substantially of the construction described an Specification 572,579, [Group XVII], and comprises a sheath 19, Figs. 5 and 6, of rectangular section housing a removable base plate 22 provided with an upstanding rib 26 to engage the longitudinal slots in a pack of blades 16. The blades are arranged so that the open end of the slot of one blade is at the opposite end of the pack to that of the blade above or below and the open ends extend beyond the unslotted ends of the alternating blades as shown in Fig. 6. An arched spring 23 presses the pack upwardly so that the top blade contacts the underside of inturned flanges 20, 21 forming the top of the sheath 19. Projections 27, 28 projecting upwardly from the base 22 engage holes 18 in the blades to locate them in the magazine. A blade feed member 24 slidable on the sheath has feed projections 29 which engage the unslotted end of the top plate and feed it out of the magazine, the blades being fed alternately out of opposite ends of the sheath. The ends of the base 22 have grooves 37 which together with inturned tongues 39 in the walls of the sheath form guides to receive the ends of the guard 2 when it is desired to change a blade. As the guard is inserted into the grooves 37 up to end stops 38 with the open end of the slot 15 presented to the magazine, tongues 40 on the flanges 20, 21, engage the ends of the old blade and partially eject it after which the feed slide 24 is operated to insert the new blade and complete the ejection of the old blade. Specifications 572,582, [Group XVII], 572,595 and 572,596 also are referred to.
