Title: Vehicle guidance system
Inventor: GILES CYRIL GEORGE
IPC: G05D1/02
Filed: 1962-03-09
Abstract: 1,025,355. Leader gear. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 6, 1963 [March 9, 1962], No. 9285/62] Heading H4U. [Also in Divisions G1 and G3.] The invention relates to steering a craft (land, air or water) along a path defined e.g. by an electric cable, radio-active trace, or light to keep a pair of detectors carried by the craft symmetrically disposed about the path. If the craft wanders too far off-course the signal from both detectors will decrease and the system fails. To prevent this, whenever the signal 1, 2 from either detector falls to a value PQ(P<SP>1</SP>Q<SP>1</SP>) which it would have when the signal 1 or 2 from the other detector just reaches a maximum (as the craft moves to one side or the other of the course XOX), relay for the appropriate side is operated to light an indicator lamp RL or LL, Fig. 2 (not shown), or cause the servo of an automatic steering system to apply maximum correction. Interlocking contacts may be provided on the relays in the two channels to prevent the second warning lamp operating if the deviation off course goes far enough off course for the output of the second detector to fall to a value PQ (i.e. in the areas A, D of Fig. 1). A transistor relay circuit for this purpose is shown in Fig. 3 (not shown).

Title: Friction clutch for motor cars for starting in direct speed and for the obtention ofsynchronic speed changing
IPC: F16D23/04
Filed: 1930-03-24
Abstract: 350,089. Operating friction clutches ; ; locking levers and rods. SEIDEL, A., 9, Kaiserdamm, Charlottenburg, Berlin. March 24, 1930, No. 9338. [Classes 80 (ii) and 80 (iii).] In motor-vehicle friction clutches, the declutching position of the control means is disposed between two clutching positions, one in which the friction surfaces are pressed together on depression of the pedal against resistance of the clutch springs, and the final position in which the same surfaces are engaged by the springs on release of the pedal. Latching means may be provided, adapted to hold the clutch out and to ensure " double clutching " in order to facilitate speed changing. The Figure shows the clutch disengaged, the control sleeve 14 having acted on the levers 13 to withdraw the presser-ring 12 against the springs 15. Further inward movement of the sleeve 14 brings it into direct contact with a disc 10, which thrusts the driven disc 9 again into engagement with the flywheel 16. The pedal 18 is adjustably coupled to a rod 5 slidably engaging a fixed member 1 and carrying a pivoted pawl 4, which is frictionally retained in position, preferably by a wing-nut 7, spring, and washer. The pawl 4, which is adapted to engage a pivoted spring latch 3, can only move to the left when, on full depression of the pedal, it has been knocked up by a cam 6. When the clutch is in normal engagement, a cam 2 again knocks down the pawl, which, on the next declutching movement, depresses the latch 3 and is thereby locked. The clutch facilitates starting in direct drive, particularly in vehicles having a geared-up top speed, due to the ease with which it can be allowed to slip under light foot pressure.

Title: Improvements in and relating to position control apparatus
IPC: G05B19/40
Filed: 1964-03-06
Abstract: 1,034,133. Selective signalling. PHILCO CORPORATION. March 6, 1964 [March 6, 1963], No. 9609/64. Heading G4H. In a system for moving a worktable 42 through a specified distance a counter 58 is set 57 to have a capacity corresponding to the specified distance, and clock-pulses 10, 12 are passed by a gate 14 to both an incremental motor 34, 36, 38 and to the counter until the counter becomes full, whereupon it closes the gate 14. The system described is particularly adapted for scribing lines on a semi-conductor wafer during the manufacture of mesa transistors and for this purpose the above work-table positioning system is interconnected with a scriber moving system. The scribing system is so arranged that while a solenoid 72 is energized it repeatedly performs cycles of scribe, lift and return, and in its two extreme positions it actuates limit switches 64-for the home or start position-and 46-for the end of stroke position. In operation the counter is set to the desired spacing between scribed lines. The scriber then makes one stroke (scribing the first line) and at the end of its stroke it actuates limit switch 46. This resets the counter, turns on a flip-flop 16 and opens gate 14, thereby causing motor 36 to move the work-table. Simultaneously, the scriber will rise from the work and start to return to its start position. Ideally the work-table movement will be completed before the scriber reaches its start position in which case the counter will have become full, gate 14 will be closed and a relay 60 will be energized from the counter " out " terminal. Thus, when the scriber eventually reaches its start position, even though it will then open limit switch 64, relay 60, and hence solenoid 72, remains energized, and the scriber begins its next cycle immediately. If, however, the scriber reaches its start position before the worktable has moved the required distance, opening of limit switch 64 causes relay 60 to drop out and the scriber pauses. When the counter becomes full relay 60 is again energized, holding through its contact 66, and the scriber begins a further cycle.

Title: Improvements in or relating to anion active resinous compounds
IPC: C08G12/34
Filed: 1941-08-13
Abstract: An anion exchange material is produced by reacting formaldehyde with an aminotriazine and a guanidine salt under alkaline conditions, gelling the reaction product by means of an acidic substance, grinding and drying and curing the ground material.  In general, the guanidine salt is 25-75 per cent of weight of that condensation product.  Other iron-active materials, e.g. zeolites, activated charcoal and active clays may also be employed. Specified aminotriazines are melamine, 2.4.6-triethyltriamino - 1.3.5. - triazine, 2.4.6 - triphenyltriamino - 1.3.5 - triazine, 2.4.6 - trihydrazine-1.3.5-triazine, di-amino triazines, e.g. guanamines such as formo-guanamine and lauro-guanamine and monoaminotriazines, e.g. 2-amino-1.3.5-triazine.  Other amino materials, e.g. urea, thiourea and dicyandiamide, may be admixed with the aminotriazine. The ratio of formaldehyde to triazine is between 1/1 and 5/1, preferably between 2/1 and 4/1.  Other amino compounds, e.g. urea, thiourea and dicyandiamide may be mixed with the aminotriazine. In examples: (1) a mixture of metamine, guanidine nitrate and formalin, adjusted to pH 9-10 with soda ash is refluxed and then acidified with HCl; the gelled mass is ground to pea size, dried at 60-65 DEG  C. and cured at 100 DEG  C.; (2) a similar product is made from the same starting materials with part of the melamine replaced by urea.  Guanidine carbonate may be used.  The Specification as open to inspection under Sect. 91 refers to the use of aldehydes other than formaldehyde and to the use, with the aminotriazine, of phenol, aniline, phenepene diamine or quinoline; also to other aldehyde condensation products associated with an aminotriazine-aldehyde condensation product.  This matter does not appear in the Specification as accepted.
