Abstract: 190,565. Maybach, K. Oct. 5, 1921. Controlling-apparatus, arrangements of transmission gear in conjunction with.-In a four-wheel braking system for motor vehicles, fixed abutments are arranged in the path of the compensating-levers so that if a fracture occurs in a brake-rod, one of the arms of a compensating-lever bears upon one of the abutments which then acts as the fulcrum for the lever, so that some or all of the brakes on the four wheels remain operative. In the arrangement shown in Fig. 1, the pedal-operated rockshaft 10 actuates the front-wheel brake cables 18 through connections 12, 16 and a compensating-lever 13. The compensating- lever is also arranged to operate the rearwheel brake-rods 8 through connections 19, 21, 22 to the rock-shaft 4, which may also be operated by a hand-lever. Fixed abutments 14, 15 are arranged adjacent to the compensating-lever 13, so that in the event of breakage of one of the members, such as 6, 22 or 16, one end of the lever will bear upon its abutment, and braking of the vehicle will still be possible. In a modification, the transmission-mechanism is enclosed in a casing, and all four brakes may be operated simultaneously by either handlever or the pedal-lever. A pair of fixed abutments is provided for both compensating-levers. In a further modification, Fig. 3, the compensating-levers 50, 51 for both front and rear brakes are attached to slide rods 55, 56 in the paths of which are arranged fixed abutments 48, 49.

Abstract: 719,907. Sewing-machines. BERNARD, S. S. L. Oct. 22, 1952 [Oct. 23, 1951], No. 26567/52. Class 112 [Also in Group VIII] Pieces of fabric of synthetic thermoplastic material are joined by simultaneously sewing and welding the edges whereby the fabric is prevented from fraying in the region of the seams.

As fabric is sewn by a needle 5 in the usual manner, the heated point 3 cuts the sewn edges at a short distance from the seam and at the same time welds and trims the edges. The heating of point 3 may be synchronized with the starting of the machine motor so as to avoid overheating. Point 3 may be fixed, pivoting, or interchangeable; or it may be replaced by a blade or wire.

Title: Recording instrument having a movable recording electrode
IPC: G01D9/28
Filed: 1972-06-09
Abstract: 1396160 Recording apparatus ROBERT BOSCH GmbH 9 June 1972 [11 June 1971]  26957/72 Heading G1J A recording instrument having an electrode to trace a calibration curve on a strip passing over a roller includes a group of further electrodes mounted on a head pivoted about ,the axis of the roller on a lever moved by an electromagnet against a return spring to move the head between first and second positions during which recording takes place. While recording a curve, particularly in fault recorders wherein a record strip is accelerated while a fault is being recorded, a legible record of information 16 such as time, date and number of the fault may be required related to a point of the curve. In the apparatus 10, Fig. 1, a meter needle 13 indicating against a scale 12 carries a recording electrode 14 to burn a trace in a metal coating of a record strip 15 moving round a roller 24, Figs. 2, 3 and a recording head 21 is carried by a lever arm 23 pivoted on the spindle of the roller 24. When information 16 is to be recorded, an electromagnet 25 is energized to rock the head 21 from a position I where it is obscured by the scale 12 to a position II. Electrodes 22 arranged in groups of five form multiple electrode units 29 which are carried by the head 21 and urged into contact with the strip 15 by flat springs 28, the electrodes 22 being connected by a flat cable 31 to a switch arrangement 32 and voltage pulses for delivery to each electrode 22 being generated in a signal generator 33 only when the head 21 moves in the direction I to II, While the arm rocks in this direction, seven slits 34 stamped out of a sheet metal fin on the arm 23 pass in succession between a lamp 36 and phototransistors 37 which, upon receiving the light pulses, transmits electrical pulses to switch the recording voltage on and off in dependence on the position of the head 21 so that each symbol of the information 16 is printed in a 5 x 7 point raster. Instead of a transverse row of electrodes 22 being moved longitudinally, a longitudinal column of electrodes 22 might be moved transversely. In either case the movement is at least twice as fast as the accelerated speed of the strip 15 to ensure a legible, undistorted print.

Title: Accumulating mechanism
Filed: 1947-10-08
Abstract: 638,890. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. Oct. 8, 1947, No. 27038. Convention date, Oct. 17, 1946. [Class 106 (i)] The invention relates to a cyclically operable accumulator of the type in which an impulse transmitted to a start magnet starts a wheel rotating to make entry of a digit, and an impulse transmitted to a stop magnet stops the wheel rotating, while concurrent impulses to the two magnets have no effect on the wheel. The invention is characterized by a cyclic impulsing device adapted to send an impulse to the stop magnet at a predetermined point in the cycle, and means controlled by the sensing of a designation in a record card to send an impulse concurrently to the start magnet, whereby the accumulator wheel will continue rotating if it is in motion and will remain at rest if it is not in motion. Numerical data are represented by perforations in a card 10, Fig. 3, in a 2, 1, 2, 5 code, the sensing of a hole at the first point in the cycle (representing "2") completing a circuit to a start magnet AM, Fig. 1, which, pulling over an armature 36, rocks a bell-crank 21 counterclockwise, whereby an abutment 21a is moved clear of a toothed disc 20 allowing a spring-urged dog 30 to engage with a constantly-rotating ratchet wheel 15 and so drive the associated accumulator wheel 24 and carry-over cam 26. A similar clutch-engaging action is initiated if a hole is sensed at the second point in the cycle (representing " 1 ") and at the third point an impulse is sent to each stop magnet SM by the closing of cam contacts C2. If there is no perforation in the card at the third position, the energization of the magnet SM, Fig. 1, causes clockwise movement of the bell-crank 21 and engagement of its abutment 21a with a tooth 20a of the disc 20. The dog 30 rides up the cam 20b and is disengaged from the ratchet wheel 15. Where a perforation is sensed in the third position, however, both the magnets SM and AM are energized simultaneously and the armature 36 remains in its previously set position (i.e. against magnet AM if a hole has been sensed previously, or against magnet SM if a hole is in the third position only-representing " O "). Declutching of the accumulator wheels two points after the representation of a second " 2 " is accomplished by a pin 51, Fig. 1, which engages the bell-crank lever 21 and moves it into the declutching position. Then follows the sensing of the " 5 '' holes, if any, causing re-clutching of the accumulator wheels which are again declutched by a pin 52 after the equivalent of 5 units has been entered. Carry-over is initiated by the closure of contacts C3, Fig. 3, impulses caused by the closure of contacts C1 passing through the usual contacts 39, 40, 41 according to the settings under the influence of the cams 26, Fig. 1.

Abstract: 242,292. Guerritore, O. Nov. 3, 1924, [Convention date]. Fluid - friction vibrationdampers.-A spring suspension for a vehicle comprises a suspension spring insufficient in itself to absorb the shock and associated with a brake which offers a progressively increasing resistance to the deflection of the spring, and a small and decreasing resistance to the return of the spring to the normal position. As shown, the brake comprises an hydraulic cylinder 4 connected by a ball joint 7 to an axle bracket 6, and a piston 8 having its rod 9 connected by an adjustable ball joint 10 to a frame bracket 5. The piston has apertures 16 closed by valves 11 when the axle approaches the frame, and a central passage leading to openings 15 in the piston-rod, which is tubular in form, is controlled by a rod 12 secured to the base of the cylinder and formed with a portion 12<1> of smaller cross-sectional area than the end portions 13, 14, so that the brake is substantially inoperative for small deflections of the suspension spring. The diameter of the portion 14 of the rod which comes into action when the spring rebounds beyond the normal position, is greater than that of the portion 13. A laminated or coiled spring may be used as the suspension spring. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of members secured to the cylinder walls and engaging recesses in the piston for causing the variable resistance of the brake. This subject-matter does not appear in the Specification as accepted.
