Title: Planographic printing plate and processes
IPC: B41C1/10
Filed: 1963-06-06
Abstract: 970,236. Printing processes. COLUMBIA RIBBON & CARBON MANUFACTURING CO. Inc. June 6, 1963 [June 13, 1962], No. 22492/63. Heading B6C. [Also in Division G2] A heat-imageable planographic printing plate having a flexible foundation sheet is produced by applying to the sheet an emulsified wax composition, evaporating the composition to form a heat-meltable oleophilic layer of discrete wax particles, and applying over the layer an hydrophilic coating which is capable of being penetrated and rendered oleophilic by the wax layer when the latter is melted under the effect of heat. The wax particles provide holding power for the hydrophilic coating. To provide on the plate the design which is to be printed, a heated stylus or heated type bars may be employed which melt the wax layer at the required places causing it to penetrate through the hydrophilic layer at those places and form an oleophilic design on the surface. Alternatively, an original sheet containing the design in an infra-red radiation-absorbing material is laid on the plate and is subjected to infra-red radiation. The foundation sheet is wet-strength paper; the oleophilic layer may be based upon hard wax such as carnauba wax, curicury wax, Be square wax, montan wax &c. or mixtures thereof, and is emulsified in a major amount of water. A specific example comprises in parts by weight Ouricury wax 4 parts, Be square wax 4 parts, Oleic acid 6 parts, potassium hydroxide 8 parts and water 100 parts. The layer thickness varies with the thickness of the hydrophilic coating and may be 0.0003-0.0005 inch, and the layer has a melting point of 120-200‹ F. Hydrophilic colloid and like binder materials such as polyvinyl alcohol, carboxymethyl cellulose, casein, gelatin and sodium alginate together with a filler such as clay, attapulgite, talc blanc fixed or titanium oxide may be used for the hydrophilic layer, the proportion of filler to binder ranging from 3 to 1 to 7 to 1 for thickness of coatings of 0.00005- 0.0002 inch. The coating may be insolubilized by the use of a salt,' aldehyde or like curing agent. A specific example given comprises sodium carboxymethyl cellulose 2 gms., 5% ammoniacal copper sulphate 40 c.c., chromium trioxide 0.5 gms., ferric ammonium citrate 1.0 gm., water 90 c.c. and clay 8 gms.

Title: A process for preparing fine spherical particles of thorium oxide
IPC: C01F15/00
Filed: 1962-06-15
Abstract: Fine spherical particles of thorium oxide are prepared by (a) forming a colloidal solution of thorium hydroxide nearly saturated with ammonium nitrate, by (b) dispersing the solution in a mixture of a water-miscible and a water-immiscible or partly water-miscible organic solvent, whereupon the colloidal particles coagulate, and (c) separating and calcining the particles.  Step (b) may be performed in emulsifying apparatus or by injection of the solution via a glass nozzle into the organic solvents, e.g. an ethanol/butanol mixture. Concentrated aqueous ammonia solution may be added after step (b) to harden the thorium hydroxide globules and prevent further coagulation. After separation, the particles may be washed with aqueous ammonia to remove organic solvent before calcination.  The particles are heated to above 600 DEG  C. for conversion to the oxide, and may then be calcined at 1300 DEG  C.

Abstract: 1,027,868. Saw-tooth circuits; relay-operating circuits. W. H. JOENS & CO. G.m.b.H. June 4, 1964 [June 15, 1963], No. 23087/64. Heading H3P. In a circuit for providing a pulsating ramp signal in response to an input signal x w , the signal x w  is fed to a discontinuous control amplifier 1 operating a relay 2, contacts a3, a4 of which reverse the polarity of a simulated retarded feedback .circuit 7 . . . 9, whilst contacts a1, a2 reverse the input to an integrator 4 providing the required output y. In the servo system described, assuming the error voltage x w  is such that the relay 2 is energized, the integrator 4 is fed from a source 3, giving a linearly rising output at y. Capacitor 8 charges via resistor 7 giving a linearly changing voltage x r  across resistor 10 which opposes X w . When the effective input is such as to release relay 2, contacts a1 a2 reverse giving a decrease in output at y. Contacts a3, a4 also reverse, rapidly discharging capacitor 8 so as to reenergize the relay 2. The output y thus swings in a zigzag manner about an ideal ramp characteristic. The duration of the first section of the ramp is dependent on the magnitude of x w , hence the system has a PI characteristic.

Abstract: 1319561 Programmed control of machine tools INFORMATION DEVELOPMENT CORP 19 April 1971 [4 March 1970] 23093/71 Heading G3N [Also in Division G1 and G4] A computer controlled electro-mechanical scanner for determing co-ordinates of a series of points on a 3-dimensional surface consists of a pressure sensitive probe controlling a probe driving servosystem, an incremental change in probe position in any one co-ordinate causing at that instant a computer reading of probe position in all three co-ordinates. As shown in Figs.2 and 9, which illustrate the apparatus for only one co-ordinate, the absolute position of the probe is given by the position of the probe itself, from a linearly variable differential transformer 26 feeding an A/D converter 27, and the position of the servomotor, from shaftposition encoder 52 and register 54, the two positions being combined in summer 56 and held in register 58. The position is displayed at 62 and fed to register 152 Fig.9, for comparison with the last read position held in register 150. The difference in the two registers (158) is compared with a standard increment fed into register 154 from the computer. Upon an incremental change in position in any co-ordinate the respective flipflop 164 is set to signal the computer over line 166 to read the registers 58 holding the probe position. If 164 has not been reset, indicating completion of reading, by the next increment, flip-flop 174 is set to stop the servo-motors. Register 150 is updated at each reading. The computer generates a punched tape for control of machine tools from the co-ordinate readings.  The servosystem Fig.11 drives the probe motor with a signal from the probe 14 to maintain contact with the surface, with a speed signal from tachometer 150 and with a position signal from the computer 32 which is compared in counter 156 with the signal from the motor shaft-encoder 52 and converted to an analogue signal (159) before input to the motor amplifier 152.

Abstract: 1,034,534. Rotary distributers. MINSTER MACHINE CO. June 5, 1964 [Nov. 20, 1963], No. 23522/64. Heading H2B. A rotary electric switch includes a shaft 12 which is driven by a sprocket 24 and a sleeve 36 which surrounds a reduced diameter portion 26 of the shaft. A knob 32 is slidably keyed to the sleeve 36 and carries a splined member 30 co-operating with another splined member 28 carried on the shaft 12. Pairs of rings e.g. 40, 42 are mounted on the shaft 12 and sleeve 36, each ring being of insulating material but having a part of its periphery formed of conducting material. These conducting parts on the rings of each pair are arranged in contact and each ring co-operates with a fixed contact brush 60 whereby current flows from one brush 60 associated with a certain ring to the brush 60 associated with the other ring of the pair only when both brushes 60 are in contact with the conducting parts on the peripheries of the rings. The duration of make and break can therefore be adjusted by suitably offsetting the conducting parts of the two rings of a pair. The time at which contact is made or broken is adjusted in the case of pairs of rings mounted on the shaft 22 by providing the brushes 60 in holders 58 which can slide along an arcuate support bar 68 and in the case of pairs of rings mounted on the sleeve 36 by pushing knob 32 inwards against spring 38 so as to disengage sleeve 36 from shaft 12 and then suitably rotating the sleeve.
