Title: An improved electric direction indicator for all types of vehicle
IPC: B60Q1/38
Filed: 1955-10-14
Abstract: 779,976. Road traffic signals on vehicles. TESSITORE [nee Doga], G. Oct. 14, 1955 [Jan. 28, 1955], No. 29294/55. Addition to 779,226. Class 118 (2). Modifications are made to the drive- and-return mechanism and circuit of a direction-of-turn indicator for a motor vehicle as described in the parent Specification. In these modifications the limit of travel contacts are omitted and the switch preparing the circuit for driving the indicating member 1 back to its central position is replaced by a different arrangement. The motor 9 instead of being rigidly mounted is attached to an arm 33 pivoted about an axis 34 parallel to the rotor and the drive wheel 10 is maintained in contact with the upper channel 2 in member 1 by spring loading 35. An arm 28 pivoted at 28<SP>1</SP> has a depression 29 at its lower end into which fits a projection 30 on the lower part of the indicator member 1. The arm 28 has moving contacts 31, 32 mounted on it and when drawn to one side by the operation of the indicator these rest on fixed contacts 31b, 32b or 31b<SP>1</SP>, 32b<SP>1</SP>, as the case may be. As shown in Fig. 3, operation of the control switch 14 to apply electrical energy to contacts 12a, 13a, or 12a<SP>1</SP>, 13a<SP>1</SP>, causes the indicator to be driven out in the appropriate direction moving arm 28 with it as it goes. The drive circuit to the motor is maintained until the switch 14 is returned to its central position. During this movement energy is applied over contacts 12, 13, contacts 12b, 13b or 12b<SP>1</SP> and 13b<SP>1</SP> through contacts 31 and 32 and the appropriate corresponding fixed contacts to cause the motor 9 to drive the indicator back to its central position. When this is reached arm 28 is also in its central position and contacts 31 and 32 open circuited. A resilient projection on the arm 28 co-operates with depressions 1<SP>0</SP> and 1<SP>1</SP> in a curved part of the housing to locate the arm, and thus the indicator member, in either the central or operated positions. The groove 2 in the upper part of member 1 may be provided with water drainage holes 2<SP>1</SP>.

Title: An improved method of coating articles with a cellulose material
IPC: B29C43/00
Filed: 1934-10-17
Abstract: 431,616. Covering with sheet material. NURSE, C. J., 196, Monument Road, Edgbaston, Birmingham. Oct. 17, 1934, No. 29647. [Class 93] [See also Groups V, VII, and VIII] In moulding coverings of cellulose acetate on articles such as knitting pins or dress buckles, the cellulose material is placed around the article, the aggregate is heated in an oven until the cellulose becomes plastic and the heated aggregate is then transferred to and pressed between dies at a less temperature than the oven so that the material at its inner faces, which are to be joined, is more plastic than at the faces contacting with the dies and the cellulose at such inner faces unites to form a homogeneous mass. For a knitting pin, a steel centre wire 10 is threaded into a tubular cellulose blank 11. A hollow metal button 12 is laid on a hot plate with the hole upwards and the tube 11 inserted therein and pressed down. The cellulose flows into the button to form a solid backing. The other end of the tube is then heated in an oven to a temperature not exceeding 200‹ C. until the cellulose is plastic, when it is removed through the air to forming dies 19, 20 co-operating to form a cavity 18 bounded by sharp edges and lateral holes 21. The dies may have electric heating bolts in holes 14 and are only moderately heated such as to 80‹ C. The heating prevents undue chilling of the outer faces. Superfluous material is pressed into the holes 21 and a pointed end is formed having a fin which is removed and the point polished. A dress buckle may similarly be formed from a wire covered with a cellulose tube and bent to shape. The cellulose may break at the bends, but is united into a homogeneous mass by heating in an oven and transferring to heated dies as above. The cross-wire of the buckle may be a separate wire having the prongs separated by cellulose tubes and its ends may be curled over the side wires.
