Title: Improvements in the method of making endless grommets
IPC: B29D30/48
Filed: 1923-05-10
Abstract: 216,319. Beyea F. H. May 10, 1923. Wire cores, covering by winding.-An endless bead wire for pneumatic tyres &c. is formed of a circular core wire 1 upon which is wound a crimped wire 3. The wire 3, previously formed into a helix, is unwound from a spool 4, and is laid on the core without longitudinal torsion by passing the spool therearound while maintaining its axis at a constant angle to the plane of the circular core Alternatively, the wire 1 may be omitted, the first convolution of the helically formed covering wire acting as a core for the other convolutions. At the termination of the covering operation the adjacent ends of the wire 3 are joined together and to the core by soldering, the ends of the core having been welded or soldered together. In lieu of, or in addition to the solder, a clip may be used. The bead is then stretched to the proper size to cause the wires to lie smoothly over the surface.

Abstract: 720,042. Belt gearing. TIMES FACSIMILE CORPORATION. May 19, 1952. No. 12633/52. Class 80 (1). [Also in Group XL (b) ]. A belt drive for facsimile apparatus having one or more stylus members traversed by the belt across the area to be scanned comprises two wheels, each provided with means to prevent the belt slipping laterally, the first wheel frictionally driving the belt at a speed slightly greater than that desired, and the second wheel comprising an idler portion supporting the belt and a speedcontrolling member coaxial with the first portion and having spaced controlling elements arranged to register with correspondingly-spaced engageable elements on the belt. The stylus members 18, which traverse the recording paper 12 fed by the roller 11, are carried on a belt 15 frictionally driven by the wheel 17 comprising two outer discs with a central disc of slightly smaller diameter to provide a recess co-operating with lugs 35 mounted on the belt 15. The speed-controlling disc 16 is formed with two outer discs 41, 42 rotatable on a bush 43, and a central disc 37 rotated by a synchronous motor and formed with diametrically opposed teeth 38 engaged by the lugs 35 on the belt. The spacing of the lugs 35 is such that a small gap 45 exists between the front edge of a lug 35 and a tooth 38 at the bottom of the wheel 16 so that the lug 35 moves smoothly into engagement with the lower tooth 38 when the upper tooth is disengaged from its controlling action on its associated lug. In a modification, Fig. 6 (not shown),. a shaped tooth on the inner surface of the belt is arranged to engage a correspondingly-shaped recess in the synchronously driven central disc.

Title: Controlling gear for centrifugal compressors
IPC: F04D27/02
Filed: 1928-05-01
Abstract: 292,552. Gutehoffnungsh³tte Oberhausen Akt.-Ges. June 22, 1927, [Convention date]. Regulating and controlling. - In an arrangement for preventing surging in the compressor 1, a cut-off valve 18 is provided in the suction pipe 2, and a non-return valve 5 is arranged in the discharge pipe 3 between the compressor, and the consumption network 4. A differential pressure relay 8 has a diaphragm 10 subject on opposite sides to the pressures on opposite sides of the valve 5 conveyed by the pipes 6, 7. The latter pipe 7 is continued to a cylinder containing a spring piston 12 which thereby becomes subject to the pressure of the network. The relay 8 and piston 12 control contacts 11, 13 in the circuit of the electro-magnet 16, the contact 11 being normally open and the contact 13 normally closed. As soon as " pumping " develops in the compressor, the non-return valve 5 closes and the pressure variations cause the relay contact 11 to close. The electro-magnet 16 is energized and the relief valve 19 is opened and the cut-off 18 is closed by it. The consumption causes the pressure in the net-work 4 to fall and the piston 12 moves the contact needle to break the circuit of the electro-magnet. The weight 20 then drops to open the cut-off 18 to close the relief valve 19. As normal working is resumed the pressure variations operate the diaphragm 10 to break the contact 11.

Title: A power-assisted steering gear for motor vehicles
IPC: B62D5/24
Filed: 1959-04-20
Abstract: 902,158. Steering vehicles. MULLER. F., and MULLER, M., [trading as FULMINAWERK KOMM.-GES. F. MULLER].: April 20, 1959 [April 22, 1958; Sept. 15 1958], No. 13392/59. Class 79(5). A power-assisted steering gear for a motor vehicle effective, beyond a predetermined torque comprises ring valves located around the steering shaft and axially spring-loaded against fixed stops and which are guided only by their inner peripheries and are axially slidable relatively to a control sleeve mounted on the steering shaft. The steering mechanism comprises a steering wheel 1, a column 2 through which the steering shaft extends, a casing 3 containing the steering gear and steering valve, and an oil reservoir 4 from which oil is supplied by a pump 5 to and from the steering mechanism. through lines 6 and 7. The steering gear has a drop arm 8 connected to a steering linkage through a member 9, the drop arm 8 being carried by a shaft 13. The Steering, shaft 27 is connected by a coarse thread 26 to a worm 16 which co-operates through recirculating balls 15 with a nut 14 attached to a piston 10. Steering movements are transmitted from the shaft 27 to reciprocate the piston 10, the movement of which is transmitted to the drop arm 8 through links 11 and 12. A sleeve 28 upon shaft 27 carries ring valves 34 and 35 spring loaded axially by sets of spring washers 40 and 41 and co-operating with stop rings 36 and 37 and shoulders 36a and 37a to form control gaps 38, 38a, 39 and 39a in the fluid paths from inlet and outlet 46 and 47 to opposite sides of the piston 10 through passages 49 and 50. When the steering shaft 27 is turned, steering is simply mechanical unless the torque required is greater than that which the coarse thread 26 will transmit, when, according to the direction of rotation, the shaft 27 will either screw or unscrew relative to the worm 16. whereby the ring valves 34 and 35 will close either the gaps 38a and 39 or 38 and 39a so that a fluid pressure will build up on one side or the other of the piston 10, so assisting the steering movement. In a modification, Fig. 3, the steering shaft 52 and worm 51 are integral and the ring valve 53 is mounted on a guide sleeve 54 while the other ring valve 55 is mounted on a control sleeve 56. A small axial play on the steering shaft is allowed and during a steering movement the shaft is moved by reaction in one direction or the other whereby control gaps are closed by the ring valves 54 and 55 as before.
