Title: Improvements in or relating to printing-hammer arrangements for high-speed printers
IPC: B41J9/34
Filed: 1966-09-22
Abstract: 1,095,742. Selective printing. SIEMENS A.G. Sept. 22, 1966 [Sept. 23, 1965], No. 42268/66. Heading B6F. A pneumatically-operated printing hammer 1 is urged and held in cocked position by a winding 4 of an electromagnet 3, and operated to effect impression, by pneumatic pressure released through an orifice 8 which is opened by energization of a second winding 9 which opposes the force of the other winding 4. The hammer comprises a ferro-magnetic portion 1b, a lightweight impact part 1a and an intermediate part 1c made of a material with a high internal friction, i.e. a high mechanical damping coefficient. After the operating winding 9 is energized cancelling the effect of the winding 4 the hammer is driven by air pressure to effect impression, and travels past a throttle 10 opening into a low-pressure pipe 11. From this point the hammer moves at constant velocity, strikes the type-carrier and rebounds to cocking position where it is held by the re-operated magnet winding 4.

Title: Retractable point protector for writing instruments
IPC: B43K24/02
Filed: 1959-12-22
Abstract: 915,522. Writing instruments. JOHMANN, F. T. Dec. 22, 1959 [Jan. 21, 1959], No. 43544/59. Class 146 (3). A writing instrument having a resilientlymounted writing point, has a point protector movable in relation to the barrel between positions in which it respectively shields and exposes the point, the point protector being actuated by pressing its outer end, which is adjacent to the writing point, and the writing point against a rigid surface. A shown, the instrument comprises a two-part barrel 10, 11, whose parts are connected by a threaded, tubular plug 12. Slidably mounted in the open front end of the barrel part 11 is a sleeve 21 having series of ears 23 extending radially therefrom in the space between two tubular latch members 16, 17 which are frictionally secured in the barrel. The members 16, 17 are formed with opposed cam surfaces of the shapes shown in Fig. 6. The writing unit includes a reservoir 25, a feed tube 27 which is slidable in the plug 12 and the sleeve 21, and a ball-point 28. A spring 29 biases the writing unit forwards. The sleeve 21 is biased forwards by a spring 30 which is weaker than the spring 29 and tends to hold the ears 23 in contact with the latch member 16. In Fig. 1, the ears 23 are shown in the position 1 of Fig. 6, i.e. in the bottom of deep recesses 18 in the member 16, so that the sleeve 21 encloses the ball-point 28. To expose the ball-point the user presses the writing end of the pen against a rigid surface, thus forcing the sleeve 21 and the writing unit back into the barrel against the bias of their respective springs and bringing the ears 23 into contact with the member 17 (positions 2, 3, Fig. 6). When the pen is raised from the surface the sleeve and unit are carried forwards by their springs and the ears 23 pass through position 4 to position 5 so that the front end of the sleeve 21 is spaced to the rear of the ball-point 28. The point is concealed by a repetition of this procedure, the ears 23 passing through positions 6, 7, 8, 9 to 1<SP>1</SP>. In a modification, the ears 23 may be mounted, on the barrel and the members 16, 17 on the sleeve 21. Specification 792,185 is referred to.

Title: An automatic position and draft control device for tractors
IPC: E02F3/65
Filed: 1963-11-05
Abstract: A tractor implement is moved relative to the tractor by a hydraulic system controlled by variable resistors dependent on position, and transducers dependent on load, through an electronic control system having an adjustable time constant.  In Fig. 1 (not shown) implements 1 are raised or lowered at the rear of a tractor 2 by means of a fluid-pressure motor 5 acting through a linkwork 8.  A potentiometer 10 associated with the linkwork, or a potentiometer 10a associated with a ground feeler 25, is arranged in an A.C. bridge circuit with a datum setting potentiometer R9 to control through a transistor amplifier 13, a phase-sensitive rectifier 17, and a D.C. transistor amplifier 18, the energization of electromagnets 19, 20 operating a valve 26 controlling motor 5 so that the implements are maintained in a position determined by potentiometer R9.  Filter circuits (not shown) associated with rectifier 17 eliminate response to short term transients. Alternatively, with potentiometer R11 at the other end of its travel, a number of strain gauges 9 arranged in a bridge circuit may maintain a constant horizontal force in the linkwork.  The strain gauges are so arranged in a hole in the linkwork that response to bending of the linkwork is eliminated.  The force detector may alternatively be piezo-electric, resistive, inductive, or capacitative.  A combination of both forms of control is available by selecting an intermediate position of potentiometer R11.

Title: Capacitor winding apparatus
Inventor: HARVEY PETER
IPC: H01G13/02
Filed: 1969-09-04
Abstract: 1,271,278. Winding webs. BRITISH INSULATED CALLENDERS CABLES Ltd. 3 Sept., 1970 [4 Sept., 1969], No. 43773/69. Heading B8R. [Also in Division H1] Apparatus for automatically producing wound capacitors from a composite strip consisting of dielectric and electrode layers comprises a drive for rotating a mandrel, automatic timing means for starting and stopping rotation, means for folding the leading edge of the composite strip around the mandrel, means for sensing the tension in a length of the composite strip between the mandrel and a temporary clamp for the strip and means for starting the timing means when on rotation of the mandrel an increase in tension in the said length of strip operates the sensing means indicating that the leading end of the strip has been successfully trapped. As shown in Fig. 1 strips 18, 19 of metallized polypropylene are fed from rolls 6, 7 to a former carried by retractable spindle 1. Tension monitors 12, 13 each comprise a fixed roller 16 and dancing roller 17 carried by pivoted frame 15, the movement of which actuates a friction brake on the roll spindle 3 or 4. Strip 22, e.g. of polyethylene coated polypropylene for one outer wrapping of the rolled capacitor is fed through identification marker 51 and tension monitor 14 to a wrapper arm constituted by pivoted frame 23. Hopper 24 feeds the tubular formers to loading arm 26 thence to spindle 1. Carriage 2 reciprocates and rotates between retracted and functional positions and includes (see Fig. 2) the pneumatically actuated clamp 27 and the tension sensor in the form of feeler bar 30 which is brought into contact with the composite strip just before feeding the free end of the strip to the mandrel. Carriage 2 also provides a table 46 the right hand end of which is perforated at 47 so that the free end can be held thereon by suction when required. Carriage 2 also includes means 31 for perforating the composite strip and the wrapping foil prior to severing. At the beginning of the process carriage 2 is moved to the right and raised and a pair of cranked bars 29 are pneumatically raised so that folding bar 28 is higher than spindle 1, the free end of the composite strip having been released from table 46. The bar 28 is brought over the former to tuck in the tree end of the strip, and rotation of the spindle is started. If the free end is successfully wrapped, rotation ceases while clamp 27, feeler bar 30 and folding arm 28 are retracted, then winding restarts. After a predetermined number of revolutions, the winding motor is decelerated and stopped, the carriage 2 is retracted, the wrapping film is pressed against the roll and introduced into the nip between the roll and the composite strip by restarting the winding motor briefly. The composite strip is perforated and severed and about six turns of wrapping film wound on and sealed by heat sealer arm 34 and pad 35. The roll is ejected from shelf 52 into assembly 53 to 59 where a loose outer turn of wrapping film is lightly sealed to the roll.

Filed: 1974-10-10
Abstract: 1469689 Cross - bar switches INTERNATIONAL STANDARD ELECTRIC CORP 10 Oct 1974 [18 Oct 1973] 43911/74 Heading H1L and H1N A cross-bar switch operating mechanism comprises for each cross-bar 77 a non-magnetic end piece 73 fixed to the bar and pivoting it in the frame-yoke 47, the end piece having an arrangement of nipples 41, 42 and projections 40 which co-operate with two armatures 89 of two respective electromagnetic actuators on either side of the cross-bar to rotate the bar in one direction or the other, a stack of contact springs 98, 99, being associated with each bar and are operated by a projection 86 of the armature to indicate the position of the cross-bar. The end piece is made of plastics material. Two springs 60, 61 acting on a projection on the end piece, Figs. 5, 6, not shown, normally reset the crossbar and damp its oscillations. If the cross-bar however is mechanically blocked in the operated position it is necessary to retain the armature in its operated position to indicate this blockage and this is done by the nipples 41 and 42. The armature is constructed to have a spring 90 holding a counter plate 84 on to the armature body 85, Fig. 8, not shown, so that the air gap between the armature and the pole face 102 of its associated actuator can be controlled. To give a positive action to the cross-bar, if it has rotated under the action of one actuator and the other actuator should be energized the air gap of this other actuator will be too large due to displacement of its armature by rotation of the cross-bar for this energization to have any effect on the cross-bar, thus avoiding faulty actuation. In the whole cross-bar switch the actuating mechanisms of the individual crossbars may be alternately positioned at one end or the other of the cross-bars, or all at the one ends.
