Patent GB-769625-A (GB)
Abstract: 769,625. Data-storage apparatus, mechanical. PAILLARD SOC. ANON. April 6, 1955 [May 17, 1954], No. 10033/55. Class 106 (1). In a number storage device for a calculating machine, the digit registering members are mounted on a support adjustable into three positions relative to a locking member for the registering members, in which three positions the registering members are, respectively, (1) released and in the path of differential members of the calculating machine, (2) locked and in the path of differential members and (3) locked and out of the path of the differential members. Fig. 1 shows two orders of a device for storing quinary numbers. Each registering member comprises a spring-actuated lever 4 pivoted to a common support 7, the end 4d of the lever being adapted for engagement with an arm 8 of a differential bar 9 of the calculating machine and with any one of five retaining slots 3 communicating with a clearance opening 2 in a stationary locking plate 1. The carrier 7 is shown in position (1), the lever end 4d being located in the clearance 2 so that the lever 4 can be set to a digit value by means of the differential bar 9. Upon movement of the carrier 7 one step to the left, the lever end 4d enters the retaining slot 3 corresponding to the set value but still within reach of the arm 8 so that the bar 9 can be adjusted to the set value when reading-out. Upon movement of the carrier 7 one step further to its third position, the lever ends 4d pass clear of the arms 8 so that the differential bars 9 are free to operate unchecked by the set levers 4. In Fig. 4, is shown one order of an arrangement of three storage devices similar to that of Fig. 1 except that the . differential bar 9 is used only for entering values, a separate bar 99 being provided for reading-out. The bar 99 is also adapted for entering values into the calculating mechanism M under control of amount keys 52. During a machine operation, the bars 99 and 9 are released to springs 54 and 53 by means of coupled eccentrics 56 and 55 in order first to read-out an amount set in one of the three storage devices and then to enter a calculated result in another storage device. The levers 4 may be replaced by bars movable laterally in transverse slots in the carriers 7. In Figs. 7 and 8 they are replaced by sectors 4g pivotally supported by a carrier shaft 7 and movable axially with the shaft. Teeth on the sector co-operate with a locking bar 26 provided with a clearance slot 27, whilst an arm 4f of the sector co-operates with the arm 8 of the differential bar 9. In a further modification, the sector 4g of Figs. 7 and 8 is replaced by a radius arm cooperating with a part cylindrical locking plate formed with a clearance opening and slots similar to the locking plate 1 of Fig. 1.

Title: Coating Composition
IPC: C09D7/65
Filed: 1979-01-08
Abstract: In the composition, the film- forming material consists of (a) 30- 85% by volume of disperse phase particles of size 0.01-20  mu m of which >/=50% are polymer microparticles, stably dispersed in (b) 70-15% by volume of a liquid continuous phase which is capable of curing by a condensation polymerisation reaction, the total volume of components (a) and (b) being 100% and the disperse phase being capable of taking part in the curing reaction. A dispersing agent is employed, the molecule of which contains (i) a polymeric component solvatable by the continuous-phase liquid and (ii) another component which is relatively non-solvatable thereby and which can associate with the microparticle surface or which can react with the microparticle polymer. The composition may take the form of a "one-pack" or "two-pack" system. The composition can have a very high solids content and makes possible the production of thick films free from surface shrinkage.

Title: Preparation of phenol and formaldehyde
IPC: C07B61/00
Filed: 1979-03-20
Abstract: Equimolar amounts of phenol and formaldehyde may be prepared from oxygen and toluene. The catalytic oxidation of toluene, when carried out in the presence of acetic anhydride, forms phenyl acetate and methylene diacetate. Pyrolysis of these two intermediates yields phenol and formaldehyde. In a like manner, hydroquinone or resorcinol may be obtained from cresyl acetates. It has also been found that benzylidene acetate may be converted to phenyl acetate and methylene diacetate by acid-catalyzed reaction in the presence of oxygen and acetic anhydride.

Title: Rope tension limiting device
IPC: B66C1/12
Filed: 1979-04-19
Abstract: A tension control device includes a rope housing block 2 having a channel 4 extending along its length in its central longitudinal plane. A housing plate 10 having a concave lower edge 12 slides in the channel 4. The plate lower edge 12 and the channel base 8 define an aperture 13 to receive a rope therethrough. The block 2 slides in a pressure means comprising a frame 18 and a top plate 20. A rope 30 is laid along the channel base 8, and the housing plate 10 is lowered into the channel 4. The combined block 2 and housing plate 10 are slid into the frame 18, and a control knob 22 is rotated to screw a shank 24 into the frame 18 thereby causing the top plate 20 to press the housing plate 10 against the rope 30. The control knob 22 is rotated until a preselected pressure is exerted on the rope 30 by the plate edge 12 and the channel base 8; this pre-selected pressure being proportional to the maximum tension to be exerted on the rope. <IMAGE>

Title: Power supply circuits with undervoltage protection
IPC: H02H3/24
Filed: 1979-05-08
Abstract: An undervoltage protection circuit for a load 4 comprises a comparator IC1 which compares the supply voltage with a desired reference level and a relay RL1 controlled by the comparator. The relay (RL1) has separate closing and opening coils 12, 11. When the supply is first switched on - and assuming its voltage is adequate - TR1 switches on and a pulse is thus supplied to the closing coil 12 via C3 and TR3. When the supply is switched off, TR4 pulses the opening coil 11 to reset the relay. If the supply voltage falls during use, TR1 will switch off to pulse the opening coil 11 via C2 and TR2. <IMAGE>
