Abstract: 1408303 Credit card checker SAABSCANIA AB 5 Sept 1972 41197/72 Heading G4M A credit card checker has a plurality of terminals each containing a keyboard entering data into a shift register, an indicator displaying the entered data, and if required a card reader, and a central unit containing a memory holding e.g. identities of invalid credit cards. A call key on the keyboard sends a signal via a telephone line to the central unit which returns a signal to an indicator lamp when connection is made. A number is entered, stored, decoded to binary form and serially transmitted. The number may be transmitted twice or may contain redundant information or a parity bit for error detection purposes. The number is received at the central unit, error checked, e.g. by reading the duplicated number into two registers and comparing them and the number is compared with data serially read from the store in the central unit. If the equality does not occur (e.g. the card is valid), a green lamp is lit at the terminal, otherwise a red lamp is lit. A further lamp is used to indicate that the received number is incorrect. Each number received at the central unit can be printed.

Abstract: 1,244,874. Lock nuts. R. BEAUPERE. 29 Aug., 1968 [22 Sept., 1967], No. 41308/68. Heading F2H. A lock nut comprises an hexagonal base portion and an initially frusto-conical upper portion which is deformed so that the upper end of the threaded bore 1 has an oval cross-section. The nut may be formed of metal or plastics and a punch is used to deform the bore. In a modification the conical portion of the nut is provided with an axially extending diametral slot thus forming two jaws which are pressed together at their upper ends by the punch to form the oval portion of the bore. A further modification is described in which the base 13 of the nut is flat over its entire cross-section and the adjacent end of the bore has a concentric recess to enhance the locking effect when the nut engages the surface of a workpiece.

Abstract: 1,270,137. Condensation of vapours of sublimable materials. DUETSCHE GOLD UND SILBER-SCHEIDEANSTALT. 20 Aug., 1969 [20 Aug., 1968; 2 Nov., 1968], No. 41488/69. Heading BIB. [Also in Division F4] Vapours of a sublimable material, e.g. cyanuric chloride, iodine, naphthalene, anthraquinone, are condensed into a solid form by passing the vapours through pipe 4 into a chamber 1 which is vibrated by mechanism and is cooled by a film of liquid, e.g. water, flowing down the outer wall. Chamber 1 is surrounded by a stationary chamber 2, and water is sprayed through tubes 3 into the space between the two chambers. The solid condensate is shaken off the vibrating inner wall of chamber 1, and is discharged through outlet 5. Propellor 6 maintains turbulent motion of the vapour in chamber 1. Alternatively, turbulence may be maintained by withdrawing some of the vapour from the lower part of the chamber, and re-introducing it into the top of the chamber by means of a fan. The vapour may be diluted with a gas. The vibrator-mechanism may be of the pendulum- or rotary type, or an electromagnetic vibrator may be used.

A device for automatically parting a running out web 3 drawn from one roll to a web drawn from a replacement roll 2, comprises a member rotatable about a spindle 6 and carrying a brush 4 and a knife 5 at opposite ends thereof. When replacement is to take place the speeds of the webs are equalized by means not shown and a photo-cell 12 is connected up, which on receiving light from a mirror 15, rotating with the new roll, operates a solenoid valve mechanism controlling fluid flow to a cylinder 9 to cause a piston therein to move upwards. The spindle 6 is thus rotated so that the brush 4 is pressed against the web 3 to cause it to adhere to the pasted surface of the roll 2. A timing mechanism restores the piston to its middle position. When next the light from mirror 15 falls on the photo-cell 12 the latter controls the flow of fluid to cylinder 9 to move the piston to its downward position, so rotating spindle 6 to bring the knife 5 into contact with the web 3. After the cutting action the device is again restored to its middle position by a timing device which also disconnects the photo-cell.

Abstract: 1505760 Railway braking systems WABCO WESTINGHOUSE SpA 20 Oct 1975 [31 Dec 1974] 43034/75 Heading F2F A supplementary reservoir 16 recharges an auxiliary braking reservoir 11 through a relay valve 13 when the pressure in a train pipe 9 increases at greater than a predetermined rate after a brake application in a braking system with one or more brake cylinders 10 supplied with pressure fluid from the auxiliary reservoir 11 by a distributer in response to a fall in brake pipe pressure, the auxiliary and supplementary reservoirs 11 and 16 being recharged from the train pipe to its working pressure in the brake released condition.  The arrangement permits a faster increase in train pipe pressure than if the auxiliary reservoir is supplied solely from the train pipe to release the brakes faster. The relay valve 13 has a valve element 15 controlled by a piston 14 subject to the force of a spring 48 and air pressure in opposed chambers 29 and 30 connected to the train pipe directly and through a restriction 24 with a one-way by-pass 25/26 respectively. On slow increase in train pipe pressure the spring 48 holds the valve shut but on fast increase in pressure, due to the restriction 24 the higher pressure in the chamber 29 depresses the element 15 allowing the reservoir 16 to charge the auxiliary reservoir 11, which may be of half the volume, through conduits 19, 20 and 27 and a check valve 28. The reservoirs 11 and 16 are recharged from the train pipe respectively through conduits 38 and 40, the distributer chamber 42 and a check valve 8 and through conduits 17, 19 and either a single check valve 18 like the check valve 8, when the reservoirs charge simultaneously (Fig. 1, not shown), or through a pair of check valves 18, 51 and a restriction 52 when the auxiliary reservoir 11 recharges faster than the supplementary reservoir 16. The distributer includes a first piston 1, responsive to train pipe pressure acting in chamber 42 and the pressure of a control reservoir 12 acting in chamber 37 to rise when the train pipe pressure falls, and a second piston 2 which is subject to brake-cylinder pressure in chamber 45 and exhaust pressure in chamber 4 and which controls a triple valve 6, 7 to connect the auxiliary reservoir 11 to the brakes.

Abstract: 1447668 Photo-electric vehicle wheel angle measurement SUN ELECTRIC NEDERLAND NV 13 Sept 1973 [13 Sept 1972] 43100/73 Heading B7H [Also in Division G1] Toe-in and camber angles of vehicle wheels are measured by projecting a pattern of marks or lines towards a mirror mounted on the wheel, from which the pattern is reflected to form an image in a plane adjacent the projector, relative movement being effected between detector(s) viewing the image plane and the image, to develop signals which may be timed or counted to evaluate said angles. In Fig. 3, toe-in or toe-out is measured by projecting patterns of parallel lines at the wheel mounted mirrors 26, 27 which reflects the light to form images 28, 29 of the pattern in image plane surfaces 22, 23 on which are mounted photo-cell 31 and 33 respectively. Relative movement is here provided by manual rotation of the wheels with the steering wheel, from a left full-lock. A counter is started when the pattern 28 on screen 22 reaches photo-cell 31, and counts pulses representing the passage of lines thereacross until the pattern 29 on screen 23 reaches photo-cell 33. The number of pulses counted represents the toe-in angle between the two wheels. For toe-out, cell 33 provides the pulses to be counted. Cell 34 checks the starting position has been attained. The logic and counting circuit for analysing the detector output pulses is given in Fig. 4 (not shown). In other embodiments, the relative movement is not provided by moving the wheels but causing the projector/receiver structure to effect scanning. In the embodiment of Fig. 5 for measuring the camber of a wheel having mirror 50 attached thereto, a projector 51 of a pattern of parallel lines is mounted on surface 52 which is pivoted back and forth by crank wheel 55. A counter is started by a mechanical sensor and it counts pulses from photo-cell 59, until an extended line 57 passes further photo-cell 60. The circuit of Fig. 6 (not shown) gives a count read-out (69) and directional indication (71). By using a projector system pivoted about a vertical axis toe-in may be measured. A system similar to that of Fig. 5, measures angle of camber, with the projector axis of tilt vertical, by the use of a pattern of parallel lines of triangular area, Fig. 7 (not shown).
