Title: Improvements in brackets or like supporting means
IPC: A47F5/08
Filed: 1959-02-04
Abstract: 870,294. Brackets; garment racks. PATTENDEN, B. Jan. 28, 1960 [Feb. 4, 1959], No. 3969/59. Class 52(5). An article supporting bracket 1 comprises a substantially rectangular frame having at its top portion a rectangularly shaped tubular portion 4 adapted to adjustably receive means 7 or 11 for connecting the bracket to a wall or a door, the frame having means for receiving articles to be supported by the bracket. The bracket has a main closed body portion 2 with openings 3. Grooves 8 are provided for the reception of coat hangers or culinary articles. The means 11 for connecting the bracket to a support may comprise a strip of metal or synthetic resinous plastic material having a pair of arms 12, 13. The tubular portion 4 is provided with a series of holes 16 for engagement with a projection 15 on the arm 12. Alternatively screw means may be passed through the holes 16 to engage holes 16a in the arm 12 to hold the arm in an adjusted position. The support for the bracket is arranged between the arm 13 and a further tubular portion 5 of the bracket. The tubular portion 5 is provided with holes 9, 10 into which resilient grommets may be fitted. A grommet 14 is also fitted on the arm 13. The bracket can be directly attached to the wall by removing the arm 12 from the tubular portion 4 thus leaving the holes 9, 10 accessible for engagement with screws or nails. A hook shaped member 7 for engagement with a picture rail, for example, may be adjustably or non-adjustably connected with the tubular portion 4. The bracket has a tubular portion 6 having holes 6a for engaging screws or nails in a support. The bracket may be constructed from metal or from a synthetic resinous plastic material. The holes 6a, 9, 10 may be of key-hole shape.

Title: Improvements in a cupro-ammonium process for the production of artificial filaments
IPC: D01F2/04
Filed: 1940-03-04
Abstract: 538,966. Artificial silk. ASAHI-BEMBERG KENSHI KABUSHIKI KAISHA. March 4, 1940, No. 4056. Convention date, June 23. 1939. Drawings to Specification. [Class 2 (ii)] In the manufacture of artificial silk from cellulose dissolved in a cuprammonium solution which is spun into a water bath and the spun filaments treated in an acid bath for completing the coagulation and fixation, the cuprammonium solution is prepared from copper hydroxide recovered from the process ; ammonia is removed from the water bath so that the copper hydroxide is deposited and removed from the bath which is repeatedly used while the acid bath is subjected to electrolysis, metallic copper being produced and sulphuric acid being regenerated so that this bath is also repeatedly used, the copper being electrolysed to form copper hydroxide which is also used for forming the cuprammonium solution. The ammonia from the used water bath may also be used in dissolving the cellulose or it may be recovered as ammonium sulphate. The cuprammonium solution, at the starting of the process, is preferably prepared by the mixture of ammonia and copper hydroxide so that no sulphate radical is produced in the cuprammonium cellulose solution. A small quantity of tartaric acid or glucose may be added to the water bath to prevent the copper hydroxide deposited therein from floating on the bath. When the ammonia is to be recovered from the water bath for use in dissolving the cellulose, acidic ammonium phosphate or borate is employed as an absorbent. The Specification as open to inspection under Sect. 91 comprised the use of the hydrogen, produced in the electrolysis of the copper, as a raw material in the manufacture of ammonia. This subject-matter does not appear in the Specification as accepted.

Title: A Timer for Controlling the Operation of a Machine and particularly a Vending Machine
IPC: G07F13/06
Filed: 1967-01-27
Abstract: 1,171,336. Dispensing beverages. E. W. BLISS CORP. 27 Jan., 1967 [8 Feb., 1966], No. 4056/67. Heading A4T. [Also in Division G3] An electric control system particularly for a vending machine comprises a timer motor driving a cam, and a differential gearing, one member of which is rotatable by one or more machine operations from an initial position into a pre-selected position from which it is returned by rotation in the opposite direction to its inital position by a drive mechanism activated by one or more different machine operations. In a coin operated vending machine of the type which dispenses a cup and a packet of a dry ingredient such as coffee or soup, and which dispenses a predetermined quantity of hot water an operation of a push button, a timer motor 60 drives a cam 64 (Fig. 4, not shown) adapted to actuate a switch SW1 at intervals each sufficient for the filling of a cup with hot water. The timer motor 60 also drives through gearing (not shown) a shaft 35 on which is mounted a differential gearing 34 which includes a toothed member 36 rotatable by a lever 25 on energization of the solenoid 22 to rotate a further differential member 46 to displace a head 47 thereon from the actuating arm 48 of a switch SW2. The rotation of the shaft 35 causes the member 46 to rotate so that after a predetermined period the head 47 actuates the switch SW2. When a coin is inserted into the machine a cup and a packet of ingredient is dispensed by operation of a lever (not shown) and a switch SW4 closes to energize the solenoid 22 and rotate the differential member 46. A push button is then actuated to close a switch SW5 to energize a relay CR1. A holding circuit for the timer motor 60 is then established via contacts CR1-1, and the closure of contacts CR1-2 energizes the solenoid valve 18 through which hot water is dispensed into the cup. After a time sufficient to fill the cup the timer cam actuates switch SW1 to de-energize the relay CR1. The solenoid valve 18 then closes but the timer motor 60 continues to be energized via lines 71, 75, and switch SW1 until the latter is restored to its original condition. If one coin only has been inserted in the machine the head 47 will now have opened switch SW2, but if the head 47 was displaced initially by the insertion of more than one coin the switch SW-5 may be closed by repeated operation of the push button until all the delivered cups have been filled.

A pivoted lever 28a, shown in Fig. 6 in the inactive position resting on a stop 34, is raised by the action of lug 45a on x spring plunger carried by the pivoted connected parts 35a, 36a directly acting upon lever 28a. Other forms of latches, including laterally-springing ones, are also described. In the construction shown in Fig. 14 the door 12d is lifted by a ramp 67 engaging a pad 66 on the door underside, the latch 18d being withdrawn by a wire brush 66.

A silver salt diffusion transfer process in which a silver halide emulsion with a water-permeable cover layer is imagewise exposed and developed and is treated with a silver halide solvent to produce a silver halide complex and contacted with an uncoated paper, felt or textile receiving sheet wetted with an acidic or alkaline solution containing a stannous salt which is capable of reducing silver halide complexes and thus producing a positive image on the receiving material and removing the receiving material from the water-permeable layer which remains on the emulsion. Alternatively the two solutions may be combined when alkaline and the two materials wetted with the combined solution. The stannous salt specified is stannous chloride and this solution may contain metallic tin, ascorbic acid or hydroquinone.
