Title: Load hoisting and supporting apparatus
IPC: B66C11/20
Filed: 1950-01-31
Abstract: 686,183. Butchers' fittings. NEAVERSON, R. A. May 26, 1950 [Jan. 31, 1950], No. 2441/50. Class 116 [Also in Groups XXV and XXX] Meat hooks 6, Figs. 2 and 5, are transferred by a split lifting hook 30 on a pulley block 21 to and from one end of a number of parallel rails 2. The pulley block 21 is suspended from a trolley 12 by a cable 17 passing round a pulley 20 on block 21 and over two pulleys 16 on the trolley 12, one end being fixed while the other is connected to a winch or the like. By this means trolley 12 can be moved along transverse tracks 1a, 1b to a position opposite the end of any rail 2 without affecting the height of the pulley block. Rails 2 are of I- section and have a depending flange 2' provided with 'holes 5 to receive extra or spare hooks. The hooks have a lower supporting bar 9, Fig. 5, and an upper bar 10 gapped at 11 for accommodating the vertical web of a rail' 2. The hooks are loaded on to the rails 2 by placing the bar 9 of a hook on the lifting hook 30, and raising block 21 by the winch until the bar 10 first engages the cam surface 31 on the end of flange 2', which unbalances the hook, and then engages surface 36b on the end of, a latch 36 pivoted at 37 to rail 2, so that it slips under the latch and on to rail 2, where it is held by the latch. During transfer of the hook pulley block 21 is positioned by a projection 32 on the end of rail 2 engaging between two members 34, Fig. 4, on the adjacent face of the block while the remote face of the block engages the sloping face 35c of a member 25 pivoted at 40 to cross bars 13 of the trolley. A vertically sliding bar 28 in member 25, to which bar an upstanding bolt 24 is attached, is urged upwardly by a spring (not shown) so that bolt 24 engages between two blocks 22a, 22b on the track la so as to position trolley 12 correctly opposite the rail 2 and at the same time to press block 25 against pulley block 21 whereby the latter is held against the end of rail 2. To unload hooks block 21 is further raised so that members 34 engage a. plate 38 secured to latch 36 so as to raise the latch to free the hooks on the rail 2. At the same time the points of hook 30 rise to a position just under the end of the lower flange 2c of rail 2 so as to receive the upper supporting bar 10 of a hook from the rail 2, the block 21 being steadied by a projection 39 and members 34 on it entering respectively between the side members 12a, 12b, and between the cross bars 13. of the trolley 12. To move the trolley opposite another rail the bolt 24 is withdrawn by pulling on a rope attached to the bar 28.

Abstract: 1,021,332. Automatic temperature-control systems. VAN DER HEEM N.V. Jan. 21, 1963, No. 2482/63. Heading G3R. In a control circuit for the heater 4 of an electric blanket, in which a desired temperature set by an adjustable resistor 5 is maintained by opening and closing a relay contact 3 whose operating coil 2 is connected to a transistor 1 and negative-temperature-coefficient sensing resistors 8 in the blanket, permanent closure of the contact 3 by an open circuit of the resistors 8 is prevented by a guard transitor 9 which becomes non-conductive upon such open circuit. Sensitivity is improved by a resistor 12, and a compensating transistor 13 and resistors 14, 15, 16 are provided to reduce the negative feedback produced by resistor 12, the symmetrical connection of transistors 1, 13 producing ambient temperature compensation. Resistor 11 may be omitted if the transistor 9 is of a type having very small collector leakage current when on "open base connection".

Title: 2-deoxyuridines and their use in pharmaceutical compositions having anti-immune activity
IPC: C07H19/06
Filed: 1962-01-24
Abstract: The invention comprises 21-deoxy-4-thiouridine and its preparation by heating a 31,51-di-o-acyl-21-deoxyuridine is heated with phosphorus pentasulphide and deacylating the product under mildly alkaline conditions.  In an example, 21-deoxyuridine is heated with benzoyl chloride in pyridine to give 31,51-di-o-benzoyl-21-deoxyuridine. The latter compound is then heated in pyridine with phosphorus pentasulphide to give 31, 51 -di - o - benzoyl - 21-deoxy-4-thiouridine, which after treating with N sodium methoxide in methanol yields the desired 21 - deoxy - 4 - thiouridine. The product is used in pharmaceutical compositions (see Division A5).ALSO:Pharmaceutical compositions having anti-immune activity comprise 5-bromo-21-deoxy-uridine or 21-deoxy-4-thiouridine together with a pharmaceutical excipient.  The compositions may also include, as additional active ingredient, 6-mercaptopurine or thioguanine (2-amino - 6 - mercaptopurine).  The compositions may be used in the form of tablets, capsules, ampoules, suppositories and ointments.  Other optional ingredients include flavouring materials, preservatives, antioxidants and bacteriostats.  (For the preparation of 21-deoxy-4-thiouridine see Division C2.)

Title: A method of zone melting of solid bodies and devices for carrying out this method
IPC: C30B13/28
Filed: 1960-01-27
Abstract: In the zone melting, by induction heating, of a vertical rod of silicon held between two driving members, initial formation of the molten zone allows limited downward movement of the upper or lower solid end of the rod in relation to its respective driving means under the action of gravity so as to close one or more electrical contacts and initiate operation of the two driving members.  As shown in Fig. 1, a driving shaft 7 has a pin 8 which is slidable in a slot 9 in a quartz holder 4 for the upper end of a silicon rod 1.  The lower end of rod 1 has a quartz holder 5 and a driving shaft 6. Initial relative movement of driving shaft 7 and rod 1 to bring pin 8 into the position shown may be terminated by electrical contact between pin 8 and the lower end of the <PICT:0927695/III/1> <PICT:0927695/III/2> slot.  Downward movement of the upper end of rod 1 may bring pin 8 and blade 10 into contact, thereby initiating joint downward movement of driving shafts 6 and 7 and rotation of shaft 6. As shown diagrammatically in Fig. 2, an electrical contact pin 14 on a holder 13 first makes contact with electrical contact members 15 (for halting relative movement between holder 13 and driving shaft 11) and 16 (for starting high frequency heating) and then with electrical contact members 17 (for starting downward movement of shafts 11 and 19) and 18 (for starting rotation of shaft 19).
