Filed: 1939-02-28
Abstract: 529,507. Course indicators for sea-going vessels and aircraft. REYNOLDS, L. G. S. Feb. 28, 1939, No. 6489. [Class 97 (ii)] An instrument for indicating the possible compass courses or points of sailing of an observed vessel or aircraft after observation of its red or green side lights comprises a compass card m and a relatively rotatable rim b marked with index pointers b<SP>2</SP>, c<SP>2</SP> and with two arcuate zones d, e extending in opposite directions over the ten points of the compass (or 110 degrees for aircraft) from points p, q substantially diametrically opposite the index pointers. Further rotatable members s, w marked respectively " your own ship " and " wind " are also provided. In using the instrument, the ship outline s is turned to point along the line of the ship's course (north, as shown) and in the case of a sailing vessel, the wind indication w is turned to show the direction of the wind. The rim k is then turned to set the red or green index c<SP>2</SP> or b<SP>2</SP> against the compass card at the bearing of an observed red or green light. The possible courses of the observed vessel or aircraft may then be read from the compass card along the range of the relevant arc e or d. If the ship is a sailing ship, the arcuate wind indicator w excludes from the possible courses those falling within 4, 5 or 6 points of the wind, these points being marked on the wind indicator. In a modification, the index pointers b<SP>2</SP>, c<SP>2</SP> are replaced by a single multiple pointer shown in Fig. 5, and pivoted centrally at h, the arcuate zones d, then both starting from a point opposite the pivot h. In a further modification, Fig. 7 (not shown), an outline ship, as shown in Fig. 5, is pivoted in the centre of the compass card, and the rim member k carries a small rotatable compass card co-axial with a rotatable outline ship marked " your own ship " which may be set to show the compass course of the user's ship.

Abstract: 417,228. Colouring and moulding artificial stone. LEWKOWICZ, L., 28, Avenue Duquesne, Paris. Feb. 28, 1934, No. 6532. Convention date, March 1, 1933. [Classes 22 and 87 (ii).] Articles of imitation stone such as designs, inscriptions &c. are made by forming in relief on a slab the outline of the design, forming a mould of the slab in which the outline in relief is reproduced as grooves, filling the grooves with any suitable material and then placing a backing in position to bind with the material in the grooves and removing from the mould. A replica of the original design is thus obtained and suitable colouring material is now inserted into the spaces between the partitions. Fig. 3 shows the original design cut in a stone slab, and Fig. 4 shows the process of obtaining a mould therefrom. The preferred material from which the mould is made is plaster of Paris. The finished product is preferably scoured and polished. In the case where designs are prepared, the heads &c. of figures may be made separately in any desired material and inserted after the main body has been polished. It is stated that the partitions are effective in keeping apart the colours used in different parts of the design. These partitions may be metal covered, for example by the Schoop process.

Title: Manufacture of colloidal sulphur
IPC: C01B17/10
Filed: 1922-03-08
Abstract: Colloidal sulphur is prepared by adding a protective colloid to a polysulphide solution, preferably an alkali or ammonium polysulphide, acidifying the solution, and filtering and washing the precipitated sulphur.  Suitable protective colloids are gelatine, glue, gum, or waste sulphite-cellulose liquor.  An electrolyte, such as sodium chloride, may be added to ensure rapid separation of the sulphur. The sulphuretted hydrogen evolved may be absorbed in alkali and employed for the preparation of further polysulphide.  According to an example, sulphur is dissolved in caustic soda by warming, glue added to the cooled solution, and sulphuric acid slowly run in while stirring.  The sulphur is separated by decantation and filtration and washed with water until free from alkali sulphate.  Reference has been directed by the Comptroller to Specification 177,103.

Title: Improvements relating to photographic shutters incorporating flash lamp synchronizing devices
IPC: G03B9/70
Filed: 1946-03-06
Abstract: 613,142. Photographic shutters combined with flash lamps. KODAK, Ltd. March 6, 1946, No. 6996. Convention date, Dec. 19, 1944. [Class 98 (i)] In an everset shutter incorporating a flash lamp synchronizing device, a trigger first moves a master member to cock the shutter and then continued movement of the trigger releases the master member which returns to make the exposure, during which an abutment on the master member engages a stationary contact, thereby completing the flash lamp circuit. Preferably, the stationary contact is adjustable to allow for lamps having different lags. As shown, the trigger 17 is pivoted at 18 on a mechanism base-plate 11 of the shutter and the master member 21 is pivoted on this plate at 26. On depressing the trigger, a shoulder 25 engages the turned-down end 20 of the master member which then rides along a shelf 39 on the trigger until this is fully depressed when, the shutter being cocked, it rides off the trigger to return to its rest position and open the exposure aperture which is closed after a predetermined interval by spring means (not shown). The shutter mechanism itself, which is not described in detail, is identical with that described in U.S.A. Specification 1,663,178. As the master member returns, the abutment 20 drops down on to an insulated contact 34 connected to a pin 32 completing the flash circuit through the casing, to which is connected the sleeve 31 of a jack 30, described in Specification 595,341. The trigger, which in returning follows the master member, re-opens the contacts 20, 34 by a knife edge 19 raising the abutment 20 which slips over the shoulder 25 on to the shelf 39. In an alternative form, the stationary contact is mounted on an adjustable slide having a contact connected to the pin 32 of the jack and adjustable by a bell-crank lever mounted on the plate 11 and having one arm pin-and-slot connected to the slide while the other protrudes through the casing in the form of a notched disc which is held in one of a number of chosen positions corresponding to " lags " of different lamps by " pimple and dimple " latches. Specification 537,209 also is referred to.

Abstract: 904,369. Vulcanizing rubber soles. LUDWIG, H., [trading as DEUTSCHE SPEZIALMASCHINEN CO. U. E. LUDWIG KOMM.- GES.]. March 2, 1959 [March 4, 1958], No. 7076/59. Class 17 (2). [Also in Group V] A porous rubber sole-and-heel is moulded on to a lasted upper, a rubber mixture being vulcanized under heat and pressure and then being allowed to expand a limited amount to form the pores. The lasts 7 are mounted on a shaft 6, which can be raised so that the lower last is clear of the mould by rotation of eccentrics 9 by a lever 10. The lasts may be exchanged by turning the shaft 6 by means of a handle 6a. The moulding and heating frames 11 and 12 are first closed and the hollow enclosed by the frame 11 and a die 16 is filled with the rubber mixture, filling layers of felt, cork or wood being placed in the mould so that the resultant sole and heel will be of uniform thickness throughout. Pressure medium is then admitted to cylinder spaces C and B, so that pistons 39, 23 rise, the travel of the piston 39 being limited by a bush 36. The die 16 and its heating base 17 are connected to the piston 23 by a piston-rod 19. When the piston 23 reaches the end of its stroke, vulcanization commences. After a certain time, the cylinder space B is exhausted and low-pressure medium is introduced into cylinder space A, so that the piston 23 and therefore the die 16 are lowered gradually against the force of a spring 29a until piston-rod 19b comes into contact with a piston-rod 38. The position of this rod is determined by the position of the bush 36 which can be adjusted for various desired thicknesses of the sole-and-heel. The pores are then formed by the expansion of the rubber mixture. After a further period of time, cylinder space C is exhausted and the pistons return to their inactive positions.
