Abstract: 441,671. Controlling motor vehicles. EVERLLNG, E., 18, Xantenerstrasse, Berlin. July 25, 1935, No. 21143. Convention date, Nov. 19, 1934. [Class 79 (v)] [See also Groups XXXII and XXXIV] In a vehicle provided with deflecting air blades 2-5, the latter are arranged to assist the steering. As shown, the inner deflecting blades 2, 4 are connected by rods or cables 10, 11 to a chain 13 riding over a sprocket 12 on the steering column. Steering movement of the hand wheel 16 deflects the blades 2, 4 so that the dead space behind the vehicle is displaced to one side or the other to assist the wheel steering. The blades 2, 4 may be initially adjusted by means of a lever 18 on the hand wheel 16 so that a side wind blowing upon the vehicle may be compensated for. Specification 349,712, [Group XXXIII], is referred to.

Title: Electrically operated stop mechanism for automatically arresting the operations of grinding machines and other machine tools
IPC: B24B49/04
Filed: 1936-08-31
Abstract: 482,741. Grinding &c. machines. LUND, Ltd., J., and SCAIFE, J. D. Aug. 31, 1936, No. 21182. [Class 60] [Also in Group XL] In a grinding-machine or other machine tool, the work 2 is contacted by a hard point 5a on a lever 5, and as the diameter of the work is reduced, movement of the lever moves a member e, which moves an armature d, thereby disturbing the electrical balance of two coils a, b of equal inductance. The coils form, with the two coils of a one to one ratio transformer P, an inductance bridge, so that when the balance of the coils a, b is disturbed, a current flows across the bridge, through a rectifier Q and through leads x, y to a galvanometer g ; current is supplied to the bridge by a transformer N from mains M and the various coils are connected by leads al, b<1>, c<1>. The pointer 14 of the galvanometer, when the work is to size, shuts off light from a lamp 18 to a photo-electric cell 17, thereby actuating a relay R, which energizes an electromagnet 25 to operate a trip-lever 25a allowing a control lover 26 to move to stop the machine. The lever 5 and coils a, bare mounted on the machine 9 in a casing 6, and the cell 17 and relay, &c. are mounted on a wall or other part unaffected by vibration. Specification 440,803 is referred to.

A mobile shaft-sinking equipment has a selfcontained unit 9 on wheels 13 which contains the winding gear, sheaves 5 being mounted on a pin 2 which hinges together the top ends of two relatively-tiltable masts 1. The lower ends of the masts are hinged to concrete foundations 4. Three sheaves 5 are provided, the central one carrying the hoisting rope and the outer ones guide ropes. In operation the winding house 9 rests on girders 14 and foundations 10. One of the masts forms a ladder with a safety rail 11. Guy-ropes 3 brace the rig laterally. To dismantle the rig the left hand bottom pin in Fig. 1 is removed and the rig slightly raised and then lowered to the ground by the winding rope which is attached to the hinge-pin 2 for that purpose. The bottom ends of the masts 1 may be attached to transversely and/or longitudinally displaceable slides mounted on the concrete foundations to facilitate adjustment of the fall of the ropes. More than one of the above rigs may be mounted to serve a shaft.

Abstract: 771,279. Sighting-levels. CONSTANTINESCO, I. July 22, 1955, No. 21330/55. Class 97(2) In a sighting level consisting of a pendulum and a sighting tube suspended for relative angular movement in a frame, the tube and a pointer attached thereto are pivoted about their centre of gravity, a linear scale is carried by or connected to the pendulum, and screw actuated means is provided for adjusting the pointer with respect to the scale. As shown, the sighting tube 2 carries a triangular pointer 3, and is pivoted in a frame 5 about an axis passing through the centre of gravity of the tube and pointer by means of a spindle 8. A pendulum 4 is pivoted about spindle 8 and carries a scale 26 co-operating with pointer 3. The pointer 3 and pendulum 4 may be clamped by a wingnut 20 on a bolt 17 passing through the pendulum and through an arcuate slot 19 in pointer 3. The head 30 of bolt 17 is screw-threaded to receive a screw 22 rotatably connected to a lug on-pointer 3, whereby pendulum 4 and pointer 3 can be relatively 'adjusted. To set the tube level, or at a desired angle, pointer 3 is adjusted to the required reading on scale 26, and the parts are clamped by wing-nut 20. The instrument is mounted upright on a staff by a socket 7, and a sighting is made. In a modification, an enlarged scale is fixed to the pendulum and extends beyond it. In other modifications, the sighting tube and pointer are pivoted to the lower end of the pendulum.

Title: Improvements relating to pneumatic tyres
Inventor: LETT GEOFFREY BROTHERTON
IPC: B29D30/54
Filed: 1953-08-01
Abstract: The process of remoulding a tyre is carried out in two distinct stages, one of which comprises applying a veneer of vulcanizable rubber to each sidewall of the tyre cover and subsequently heating the sidewalls under pressure between a pair of shaped platens to mould and vulcanize the rubber veneer to the sidewalls, and the other stage comprising applying a length of vulcanizable rubber to the outer periphery of the cover and subsequently heating the said outer peripheral portion under pressure, while located within a cylindrical curing ring, to mould and vulcanize the tread to the cover. Preferably the remoulding of the sidewalls is effected before retreading, although the order may be reversed.  In an example the sidewalls of a tyre cover were lightly buffed from the heads to the shoulders the rubber veneer applied and an air bag placed within the cover.  The cover and tube were then placed between a pair of circular-shaped platens each having attached thereto a coil of steam pipe and having rims which retain the tyre heads at any required spacing by inserting spacer rings between the rims on each platen. The cover was then subjected to heat and pressure to vulcanize the rubber veneer, the tube deflated and withdrawn after which a strip of tread rubber was applied to the periphery of the tyre the heads spread and the tyre inserted in a curing ring of the tyre described in Specification 661,627 and the vulcanization carried out as described in Specification 420,829.
