Title: Growing crystals
IPC: C30B15/22
Filed: 1970-11-09
Abstract: 1311558 Programmed crystal-pulling INTERNATIONAL BUSINESS MACHINES CORP 9 Nov 1970 [26 Nov 1969] 53156/70 Heading B1S [Also in Division G3] An on-line computer-controlled system for growing a crystal from a melt includes means for adjusting the temperature of melt and pulling rate in dependence on idealised and compensating mathematical models. As shown, the Czochralski method for growing single structured crystals from a silicon melt is used in an apparatus comprising a quartz crucible 4, containing a silicon charge the temperature of which is raised by a heater 11, enclosed within a cylindrical chamber 25. A reed 1 is lifted and rotated by a hollow shaft 3, driven by motors 5, 6 to produce a crystal 10. The crucible is rotated and lifted by a hollow shaft 5 driven by motors 8, 9. The surface of the melt 2 is observed by an operative, through a viewing port 24, who initiates the automatic control of crystal growing by an on-line computer system 12. The computer system receives over connections 13, 14, 16, 17 information relating to the speeds of motors 6-9, an indication of temperature of the melt at the bottom of the crucible over a connection 18, from a radiation sensor 30 via the hollow shaft 5, and over a connection 15, the crystal diameter as determined by a radiation sensor 31. The computer system 12 is promrammed to control the motors 6-9 through lines 19-22 and the heater, through a line 23, in accordance mathematical models. The melt temperature control is based upon a first mathematical model describing the heat energy flow into and out of the apparatus and a second mathematical model which compensates the idealized model for the uncontrolled parameters which are present in a physically realisable system.

Abstract: 1,140,927. Vehicle washing apparatus. CECCATO & C. S.p.A. 23 Nov., 1967 [10 March, 1967], No. 53461/67. Heading B7J. Vehicle washing apparatus comprises a horizontal (or vertical) rotating brush connected via ropes 2 and pulleys 3 to at least one counterweight 4 disposed in at least one water tank 5 to which water is adjustably supplied to vary the effective weight of the counterweight. In an embodiment, Fig. 1, the horizontal brush 1 is connected to a single counterweight 4 disposed in the single tank 5 communicating with a pressure vessel 6 to, and from, which compressed air is supplied via 7 and 8, and vented via 9, 10, to vary the water level in the tank 5 and hence the immersion of the counterweight 4. The counterweight 4 is heavier in air than the brush 1, but the upthrust on the fully-immersed counterweight 4 renders the brush 1 heavier than the counterweight. Alternatively, a pump may be used to feed and discharge water directly into and from the tank 5, the vessel 6 being omitted. Alternatively, water can be fed directly into the tank 5 through a tap and discharged through a valve at the tank bottom. In another embodiment, a vertical brush is mounted on a carriage slidable along a transversely-extending frame and connected via ropes and pulleys to two counterweights. One counterweight is heavier in air and is disposed in the water tank and the other is guided in a further (empty) tank, so that the brush may be urged against either side of a vehicle with equal force. Alternatively, the counterweights are equal in weight and are each disposed in a separate water tank. The frame supporting the brushes may be moved relative to the vehicle, or vice-versa.

Abstract: 1,179,553. Cooling dynamo-electric machines. MINISTER OF TECHNOLOGY. 21 March, 1967 [22 Dec., 1965], No. 54328/65. Heading H2A.  The stator winding of an electrical machine is cooled by passing coolant through the hollow conductors 2a, 3a and bending the end-windings axially outwards to fit tightly in a metal ferrule 4 having a tubular extension which seats in a hole in an insulating ring 5, this forming one wall of a coolant carrying channel 6a. As shown, the insulating ring 5 is secured in fluid-tight manner to the walls of a channel formed on the inner side of an end-plate of the machine. In a modification the ring 5 is itself conducting, in which case the ferrules 4 are held in holes therein by insulating packing. If there are four or more conductors per slot then either two rings 5 are provided to carry the required number of ferrules, or alternatively, the coolant is passed through several coil sides in series so that fewer ferrules are required. The coolant emerges in a channel at the other end of the machine and is then passed to a heat-exchanger.
