Abstract: 1290259 Differential braking for steering LIHNELL VAGN AB 27 April 1970 [6 May 1969] 20066/70 Heading B7H An emergency steering device for articulated vehicles in which the brakes 18, 19 associated with the wheels on either side of the vehicle are individually operable by means of the steering wheel 8 so that valve means 12, 13 are alternately actuated only when a force greater than normal is applied to the steering wheel to actuate the respective brake. A greater force than normal is required to overcome the springs 16, 17 and when the articulation has reached a certain size the respective emergency steering valve 12, 13 will be restored by reason of the changing angle between the articulated parts so that braking ceases. Further continued steering articulation in the same direction will actuate the other steering brake valve resulting in the vehicle being straightened out. A pressure medium 20, such as a pressure accumulator or a pressure tank supplies the brakes 18, 19 reversing valves 28, 29 ensure that only one of the brakes 18, 19 is operable under emergency steering operations.

Abstract: 1290797 Continuous casting MANNESMAN AG 22 Dec 1970 [30 Dec 1969] 60716/70 Heading B3F  In a continuous casting mould 1, two different powders 19, 21, e.g. to provide lubrication and to control heat transfer between the strand 9 and mould 1, are simultaneously added to separate regions of the melt bath 11; the powder 19 with the higher melting point is supplied to a region where there is less outflow of heat and a slower formation of the strand shell. This is said to cause a more even growth of the strand shell. As shown, a cooled mandrel 3 is used in casting a tubular strand 9 in a mould 1 fed with steel 6 from a ladle 7, and the more easily melted powder 21 is excluded from the innerwall region of the strand by a refractory ring 13. In a curved-axis mould, the more easily melted powder is confined towards the inside of the curve by a curved separator. The powders, providing different viscosity melts, are mainly of Al 2 O 3 , SiO 2 , CaO and C. The more easily melted powder may contain fluxes such as Na 2 O and CaF 2 .

The initial forming is effected at a first station 1, the seam 10 being formed by jaws 20. The station 1 includes members 18, 19 having inclined surfaces for forming the walls 13, 14, pivotable members (23, Figs. 4, 5) having tapering U-shaped grooves (25) for forming the bulges 15, 16, and folding plates 24 for forming the flat package bottom. The package is then lowered on to an L-shaped carrier 33 and severed by cutters 34, the carrier 33 transporting the package to a second station 4 at which a plate 47 flattens the package top. This flattening causes the liquid in the package to press the walls 11, 13 outwardly, the wall 14 abutting one leg of the carrier 33 and the wall 13 abutting an already formed package held between plates 40, 41 adjacent the station 4.

Abstract: 1297980 Engraving half-tone printing plates WERKSPOOR AMSTERDAM NV 16 April 1970 [17 April 1969] 18295/70 Heading H4F A half-tone printing plate which is seamless in a direction perpendicular to the direction of the line scans is produced from a master 2 having a seam 3 in that direction, the printing plate and master being mounted on rotating drums for example, by repeatedly engraving a number of points in the line direction so that the seam is entirely bridged. Preferably the points repeatedly engraved on a line are staggered in the line direction in relation to the points repeatedly engraved on the adjacent lines. As shown, the analogue video signal from photo-electric scanning element 4 is digitized, 17, and passed to the first memory cell 18 of a group of such cells 18-23 which form a shift register. These memory cells and the AND gates 25-30 are controlled by signals from screen frequency circuit 24, and signal transmitters 9 and 10 which comprises cylindrical parts 11 and 12 having one and six apertures respectively which rotate in synchronism with the drums between light sources 13, 14 and detectors 15, 16. The pulses from detectors 15 and 16 are fed to the memory cells 18-23 and to a register comprising bi-stables 33, 34 and 35, the output of which is connected to a decoding circuit 36. Each pulse from 16 increases by "1" the contents of register 33, 34, 35 and each pulse from 15 resets this register and the shift register 18-23. In operation when six points on a line have been scanned the entire register 18-23 is filled with corresponding information and when the seventh point is scanned the information relating to the first point (now in cell 23) is lost. This information up to now has been passed via gate 25 to the engraving element 6 but when the contents of register 33, 34, 35 are increased by "1" gate 26 is opened and gate 25 closed so that information relating to the point which is in the memory cell 19 is engraved, i.e. a point is engraved twice. Since six pulses are produced in one line scan (revolution) by transmitter 10 six spaced points in each line scan are engraved twice in succession, it being assumed that the width of the seam 3 is equal to six points. Circuit 43 may include a delay element with a variable time-lag so that corresponding points will not be engraved twice on adjacent lines, thus preventing the repeatedly engraved points from being disposed on a straight line.

Title: Smoke detectors
IPC: G01N21/27
Filed: 1970-11-24
Abstract: 1313877 Smoke detectors CHUBB FIRE SECURITY Ltd 21 Oct 1971 [24 Nov 1970] 58891/70 Headings G1A and G1N [Also in Division H3] In a smoke detector in which a detector circuit generates an electrical signal which undergoes a significant variation in the presence of smoke and thereby actuates an alarm LP2, the detector includes a feedback circuit incorporating a delay device C3 connected between the detector circuit output RV1 and the supply 18 for the detector circuit, the feedback circuit operating to adjust the supply circuit voltage such that the detector circuit output is at least partially compensated for variations occurring over a period the minimum value of which is determined by the delay device C3. In a photo-electric embodiment, Fig. 1, light from a projector lamp LP1 is scattered by smoke particles on to a photo-resistor PC1. A screen 16, which may have an aperture, prevents the photo-cell receiving light direct from the source. The feedback circuit includes, in addition to capacitor C3, transistors T3-T6. The voltage supplies to both the lamp LP1 and photo-cell PC1  are controlled by the feedback circuit, although in other embodiments either one of these two voltages is so controlled. Capacitor C3 ensures that long-term fluctuations e.g. of 20 mins or more, caused e.g. by lamp ageing, component value drift or dirt in the optical system are compensated for. Capacitor C1 and transistor T8 put a time constant of about 20 mins. on the lamp light-up time, but this may be eliminated for calibration purposes by closing switch SW1B. In a further photo-electric embodiment, Fig. 2 (not shown) there is a fusible element (TF1), in circuit with SCR1, which becomes open-circuit at a fixed temperature. This ensures that the detector operates at a predetermined temperature if it has not already responded to the presence of smoke. A further embodiment, Fig. 3 (not shown), employs an open ionization chamber (32) as a smoke sensor. This chamber is connected in series with a closed reference ionization chamber (31). Each chamber contains a radiation source. The reference chamber may be replaced by a resistor. The presence of a certain amount of smoke causes the voltage output to trigger an SCR and thereby actuate an alarm lamp (LP2).

Title: Ciphering machines
IPC: G09C1/12
Filed: 1960-01-12
Abstract: 1322491 Ciphering apparatus NETHERLANDS MINISTRY OF DEFENCE 12 Jan 1960 [12 Jan 1959] 1188/60 Heading G5X A ciphering machine comprises a set of permutation wheels and a reverser disc provided with contacts and wirings for passing electric pulses, all the permutation wheels being provided on one side with regular teeth which can be engaged by a pawl under the control of an adjacent permutation wheel and also being provided with a plurality of irregularly distributed projections which control the engagement of the next adjoining wheel, an adjustable mechanical transmission system being provided to couple a permutation wheel with the reverser disc. The machine shown comprises five permutation wheels 7a-7e and a reverser disc 23 which are freely rotatable on a main shaft 14. The wheels are rotated by pawls 11a-11e operated by cams 6 on a shaft 5 driven by a hand crank 2, the pawls engaging regular teeth on one side of each wheel except when raised out of contact by irregularly arranged projections on the other side of an adjacent wheel; the reversing disc 23 can be driven by any of the permutation wheels by moving a cog 28 to an appropriate position on its shaft. Each permutation wheel is provided with resilient contacts 20 on one side connected by wiring to fixed contacts 22 on the other side; the reversing disc is provided with resilient contacts 20 interconnected by wiring. The resilient contacts of the end wheel 7e make connection to contacts on a fixed wheel 56 which are normally connected through switches 54 to the 26 relays 47a, 47b. When a letter to be coded or decoded is selected by rotating a knob 30, an arm 59 opens the corresponding switch 54 and closes a switch 58, the latter earthing one of the contacts on fixed wheel 56; thus an earth connection is made to one of the relays 47 through the wheels and reverser disc and back through the wheels. The selected relay is energized when shaft 5 is rotated and changes over a contact 66 from a position where a condenser 68 is changed by a battery 60 to a position where the condenser discharges through the selected relay 47. Operation of the relay couples a wheel 41 to one of the discs 42a or 42b mounted on shaft 5 by means of a pin 45 so that when shaft 5 is rotated the wheel 41 turns through an angle, determined by the relay selected, until the pin 45 is released by a fixed member 50a or 50b. The wheel 41 drives a printing disc 33 through a toothed wheel 35, and cams 72, 73 on shaft 5 cause the coded (or decoded) letter on the disc 33 and the original letter on a printing disc 32 to be printed. In the arrangement shown in Fig. 1 the coupling between the reverser disc and one of the permutation wheels is adjusted manually, but in an alternative, Fig. 6 (not shown), the coupling can be moved automatically from one wheel to another. Specification 1,322,492 is referred to.

Filed: 1971-01-15
Abstract: 1333295 Automatic control of pressure OXY METAL FINISHING (GREAT BRITAIN) Ltd 14 Jan 1972 [15 Jan 1971] 2116/71 Heading G3R A fluid pressure switch 6 connected to two chambers 1, 2 (via pipe lines 3, 3A, 4, 4A) automatically maintains a constant fluid pressure differential between chambers 1, 2 by responding to pressure differences between its opposite sides 6A, 6B and operating a fluid pressure control circuit to adjust the fluid pressure in one chamber 2. Chamber 1 is a retort containing heaters and chamber 2 is a thin-walled gas-tight work chamber containing a workpiece being heat treated. Initially, chambers 1 and 2 are at atmospheric pressure with valve 1A closed. To start, pumps 17 and 11 are started, and valves 5, 9, and 18 opened: Pump 17 then draws a vacuum in both chambers 1, 2, these chambers being interconnected via valve 18 and junction 20 of pipes 3, 4. When chambers 1 and 2 are fully evacuated valve 18 is closed so that switch 6 is brought into the fluid circuit and chambers 1, 2 are no longer interconnected, and valve 12 is opened. Gas from source 21 then enters chamber 2 via valve 12 and pipe 4. When the required pressure difference between chambers 1, 2 is reached, switch 6 closes to energize solenoid 12A and close valve 12 cutting off the gas supply to chamber 2. Pump 11 operates throughout and reduces the pressure in chamber 2 until switch 6 opens and de-enerized solenoid 12A which opens valve 12 to restart the gas supply from source 21 to chamber 2. Valve 12 is thereafter opened and closed by switch 6 alternately allowing and cutting off the gas supply from source 21 to chamber 2 this maintaining the pressure differential across the wall of chamber 2. When the heat treatment is finished, inlet 1A is opened to admit cooling gas to chamber 1, the pressure in chamber 1 rises and switch 6 opens valve 12 to admit gas from source 21 into chamber 2 to keep up its pressure relative to chamber 1. In a modification, Fig. 2 (not shown) chamber 2 takes the form of a bellows which clamps a workpiece A, B against a support C whilst it is heat treated, brazed in the example described.
