Title: Optical projection apparatus
IPC: G03G17/04
Filed: 1970-11-09
Abstract: 1337418 Projection copying XEROX CORP 9 Nov 1970 [14 Nov 1969] 53138/70 Headings G2A and G2H An optical projection apparatus, as described (See Specification 1337416) forming part of a photo-electrophoretic copying machine 1, comprises a carriage 4 supported for travel on rails 6, (7) Fig. 1, (not shown), the carriage having a platen 26 for supporting an original and a transparent plate which functions as a moving electrode 13 when the apparatus is used in the machine; and a stationary illumination and projection assembly 28 past which the carriage is moved so that successive areas of the platen 26 are illuminated and projected on to the plate. As shown, the machine contains two such assemblies 28, 29 each arranged to project a line image to the interfaces between the electrode 13 and electrodes 9, 116. A line of the original is illuminated by lamps 54, 55 Fig.32 in elliptical reflectors 307, 308. Light passes through an aperture 318 via mirrors 311, 312, 313 and lens 314 to the electrode 13, the mirror 312 being at the nodal point of the lens 314. The assembly 29 is similar in constructions. The lamps are cooled by fluid under pressure being passed through hose 332, conduit 331 and slit 333. The assemblies 28, 29 are also cooled by a fan 48 Fig.2 and hoses 52, 53. As shown, the carriage 4 is initially at the left hand end of the machine. As it is moved to the right, the electrode 13 is cleaned by an assembly 17; ink is applied between the electrodes 9, 13 and a light image projected thereto by the assembly 28. The ink on the electrode 13 is exposed a second and a third time to the same original by the assembly 29 as the carriage 4 moves past the electrode 116, forming part of a development assembly 20 while travelling its turn position 4a and back to its initial position. The image is transferred to a web 27 by an assembly 18 and is then fixed while the web is out and a copy ejected. The assemblies 18, 19, 20 are raised or lowered appropriately by elevator mechanisms 21a-c. The carriage 4 is moved by a belt (334) Fig.14 (not shown), driven by a motor (342) which also controls the actions of the assemblies 18-20. In another embodiment Fig.15, (not shown), Fig.16, for transparent originals, the illumination and projection assembly 501 is integral with the carriage and moves therewith. A light 509, condenser and mirror 507 project a whole frame image on to the electrode 13. However, images are formed in a line by line manner as the electrode 13 only makes line contact with the electrodes 9, 116.

Title: Mass spectrometric analysis of surfaces of solids
Inventor: BENNINGHOVEN ALFRED
IPC: H01J49/16
Filed: 1970-11-10
Abstract: 1,274,580. Ion sources; mass spectrometers. FARBENFABRIKEN BAYER A.G. 10 Nov., 1970 [14 Nov., 1969], No. 53327/70. Heading H1D. In a process for the analysis of surfaces of solids by means of secondary ion mass spectrometry, a primary ion beam 4 of such low current density is used for bombarding the surface of the solid that the time required for distintegration of a monolayer of the solid is long compared with the time taken to record a spectrum, i.e. several hundred seconds. A catalyst 1, e.g. silver, to be investigated is mounted on a replaceable support 2 in a chamber of stainless steel with gold seals which is evacuated to a pressure below 10<SP>-8</SP> mm. Hg and is heated to a temperature of 450 C. The main components of the residual gas are H 2 , H 2 O, CO and CO 2 . A beam 5 of argon ions from a source 1 is reduced in diameter by a shutter 6 to form a beam 4 inclined at an angle of 70 degrees from the perpendicular to the target 1. Suitable voltages are applied to electrodes 7 to accelerate either positive or negative secondary ions towards a gap 8 leading to a single-focusing 60 degree sector field mass spectrometer provided with an open multiplier as an ion-detector. The process enables information to be obtained regarding the composition of the upper monolayers of a solid, which is not possible with ion beams of high intensity.

Title: Improvements in or relating to padlocks
IPC: E05B67/36
Filed: 1968-11-11
Abstract: 1,218,128. Padlocks. VIRO INNOCENTI S.p.A. 11 Nov., 1968 [18 Nov., 1967], No. 53434/68. Heading E2A. A patdlock comprises two barrel lock mechanisms 13, 14 of differing locking characteristics, said mechanisms having barrels 113, 114 which are coaxially arranged and connected so as to be rotatable together and actuable to latch or release a shackle 2. In the construction shown the shackle is substantially cylindrical and is slidable in bores 37 in arms 101, 201 of a U-shaped body of the padlock; the shackle has an annular groove 102 which is engaged by a latching member 11 to hold the shackle in the locking position and the shackle is biased by a spring-loaded plunger 4 so that it is normally urged towards the releasing position although if necessary the full movement to the releasing position must be completed by hand. Complete release of the shackle from the body is prevented by a spring loaded detent 10 in the arm 201 of the body which engages the groove 102 to prevent this. The plunger 4 is prevented from leaving the bore 3 in the arm 101 of the body by a stop pin 6 which engages a recess 104 in the plunger. The barrels are coupled together by a connecting link 16 which extends from the barrel 113 and engages a recess 17 in the barrel 114; the link 16 also engages a notch in the latching member 11 in such a way that rotation of the barrels from their locking positions moves the latching member to release the shackle 2. The latching member is biased by a spring 18 to the latching position. As shown each of the barrel lock mechanisms is of the pin tumbler type and both sets of pin tumblers must be disposed in the unlocking condition by the appropriate keys for each mechanism before the barrels can be rotated. The difference between the lock mechanisms can be in the height of the various tumblers and consequently in the notching of the keys whilst the number of tumblers can differ and one lock mechanism can be a pin tumbler mechanism while the other is a plate tumbler mechanism. The mechanisms can have differing numbers of rows of tumblers. Instead of the barrels being connected together by a link they can 'be made in one piece. It is also stated that the barrels can engage the shackles directly.

Title: Improvements in or relating to apparatus for sensing rate of rotation
IPC: G01C19/66
Filed: 1967-11-28
Abstract: 1,135,910. Lasers. HONEYWELL Inc. 28 Nov., 1967 [5 Dec., 1966], No. 53985/67. Addition to 1,116,416. Heading H1C. In a ring laser as described in the parent Specification in which the counter-rotating light beams are biased to different frequencies and the sense of the bias is reversed periodically, the cumulative effect of the beams locking- in to a common frequency when the bias is reversing is overcome by making the bias reversals non-periodic. As shown, the ring laser comprises a quartz block 10 with a closed optical path formed by a triangular tunnel 12, the apices of the tunnel being sealed by resonator reflectors 14, 16, 18. A gaseous active medium is introduced into the tunnel through a duct 26 which is afterwards sealed by a plug 20. Reflector 16 is partially transmitting and is backed by a detector 28 for measuring the frequency difference, due to rotation of the assembly, between the counter-rotating light beams 22, 24. As shown, a mechanical bias is used which comprises a vibrator 30 energized from a signal generator 36, the mechanical oscillations produced being periodic. These oscillations are made non-periodic by including a random noise signal generator 40 in the vibrator circuit. In a modification the mechanical vibrator is replaced by a Faraday medium and two quarter-wave plates located in the closed optical path, the Faraday medium being excited by a constant frequency generator and a random noise generator simultaneously.

Title: Improvements in analogue multipliers
Inventor: BANNER AUBREY EDWARD
IPC: G06G7/161
Filed: 1966-12-02
Abstract: 1,216,185. Multiplying and dividing circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 1 Dec., 1967 [2 Dec., 1966], No. 54136/66. Heading G4G. A multiplier/divider analogue circuit comprises an integrating operational amplifier and capacitor circuit A 1 , C 1  receiving a constant voltage + V S  over temperature compensating resistances R1a, R1b; the capacitor being shunted by transistor TR 1  switchable by bi-stable BS. With transistor open, linear integration produces a negative going output increasing with time which is applied to inverting unity gain operational amplifier A 2  together with multiplying voltage V A , to produce output increasing with time from -V A  to 0, applied to a level detector circuit comprising operational amplifier A 3  having feedback path containing resistances R6 to R9, oppositely poled diodes D 1 , D 2 , and variable resistance VR 1  setting trigger level to 0. An output positive to earth (logic 0) is developed until the output of A 2  reaches trigger level, at which the output switches to negative (logic 1) and the output of pulse shaper PS1 changes from negative (logic 1) to positive (logic 0) for application over diode D 3  of a three input AND gate also receiving over diodes D4, D5 the outputs of monostables MS1 and MS2 which are logic 1 in stable states. Thus the AND gate output switches to logic 0 to produce logic 1 from pulse shaper PS2, setting bi-stable BS to its SET state, closing transistor TR1, and opening TR2. Integrator A1 is reset after time proportional to VA. Similarly, the input of integrator A4, C2 receiving multiplier voltage Vb over variable resistance VR 2  is cut off by TR2 after time proportional to VA. Bi-stable BS on assuming SET state triggers monostable MS1 to close transistor TR4 to transmit the final output of A4, C2 to storage capacitor C 3 , and after a suitable readout time MS1 reverts, opens TR4, and triggers monostable MS2 to close TR3 for a suitable time to discharge A4, C2. MS2 reverts and triggers bi-stable BS to RESET for repetition of the cycle. The AND gate remains at logic 0 while either MS1 or MS2 are in unstable states, thus maintaining bi-stable BS at SET for the required interval. The stored signal on C 3  is applied to a high input impedance unity gain non inverting operational amplifier A5 whose output is shown mathematically to be proportional to V A  V B /V S . Squaring may be effected by holding V A  = V B  and V S  constant, while square rooting (Fig. 2, not shown) is effected by feeding back the output V M  over an inverting unity gain operational amplifier to input V S , so that V M  is proportional to #V A  V B  or to #V A  if V B  is held constant. The apparatus is applicable to a mass spectrometer as described in Specifications 1,167,341, 1,215,293 and 1,215,293 cog.

Abstract: 1300710 Integrated circuits SIGNETICS CORP 29 Nov 1971 [10 Dec 1970] 55246/71 Heading H1K The complementary vertical PNP and NPN transistors shown are formed from a single N- type silicon starting wafer 11 the (100) lower surface of which etched through apertured silica passivation using an anisotropic etch to form a groove. The groove and its surrounding area are exposed through silica film 18, and the entire collector region of the PNP transistor is formed by diffusion. The process is repeated at a further location to form the enhanced conductivity portion 24 of the collector region of the NPN transistor. Deeper grooves are then etched in the lower surface, the entire lower surface passivated, and a polycrystalline support 29 grown thereon. The upper surface of the structure is lapped to leave the isolated transistor islands, the diffused collector regions remaining just below the surface. Further diffusion operations provide emitter and base regions and enhanced conductivity contact regions. Care is taken to ensure that the collector contact regions meet the diffused collector portions which follow the contours of the grooves. Aluminium electrodes are provided. In the variant of Fig. 10 (not shown) the NPN transistor is not formed with a groove in its lower surface and diffusion into the lower face of the starting wafer at the location of the NPN transistor merely provides a normal collector sub-region.
