Title: Differential Pressure-Responsive Indicator Device
IPC: G01L7/16
Filed: 1967-05-10
Abstract: 1,193,142. Fluid-pressure actuated switches. ALFRED TEVES G.m.b.H. 10 May, 1967 [23 Aug., 1966; 24 Aug., 1966; 3 Feb., 1967], No. 21772/67. Heading H1N. [Also in Divisions F2 and G1] A device for indicating when a predetermined pressure difference occurs between two hydraulic circuits, e.g. those of a dual braking system, comprises a piston floating in a cylinder and retained in a central position by one or more centring springs, the piston dividing the cylinder into two chambers connected respectively (in series or parallel) with the two hydraulic circuits; an intermediate portion of the cylinder sealed off from the pressure chambers being provided with a pin bearing against the bottom of an annular groove; when the piston is displaced from its central position by a predetermned pressure difference, the pin is lifted out of the groove by the inclined walls of the latter. In Fig. 1, the piston 2 is retained by two springs 3, 4, each of which engages an abutment 12, 14 on the piston and a slidable stop 15, 16, the latter bearing against a further abutment 11, 13 on the piston. A pin 9 normally rests in a groove on the piston, but when the pressure difference is sufficient to overcome the force of one of the prestressed springs, the piston moves sideways and forces the pin 9 outwards. This movement may close electrical contacts to light a lamp. In an alternative form (Fig. 2, not shown) the two springs are at the same end of the piston and via movable stops (24, 25) bear against two coaxial stops, one of which (22) is fixed to the cylinder casing and the other of which (26) is mounted on the piston. One of the springs and movable stops may be omitted (Fig. 3, not shown). Reference has been directed by the Comptroller to Specification 1,149,719.

Abstract: 354,977. Feeding webs. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Richter, C. J. ; 2304, Lombard Avenue, Berwyn, Illinois, U.S.A.) July 19, 1930, No. 21914. Convention date, Dec. 14, 1929. [Class 100 (i).] Web-roll braking devices.-In a web-roll braking device for printing and other machines in which a pilot roller engaging and responsive to variations in the tension of the web controls the action of the brake, the brake consists of friction belts engaging the roll surface and provided with weighted means for periodically moving the belts to maintain them in contact with the roll. A number of belts 25 engaging the roll 14 are attached at their lower ends to a shaft 26 and at their upper ends to pulleys fixed to a shaft 30 on which is also fixed a pulley 37 on which is wound a cable 35 carrying a weight 33 which tends to wind the belts 25 on their pulleys. The weight is normally held inoperative by a brake comprising arms 41 carrying brake shoes 40 engaging a drum 39 on the shaft 30, the arms 41 being yieldingly connected by a rod 44 and spring 45. A pilot roller 48 pressed by springs 58 into contact with the web 49 is connected to a pair of arms 50 pivotally mounted by means of a shaft 51, and carrying a shaft 60 on which are mounted pulleys 59 round which the belts 25 pass. The arms 50 are connected by slotted links 67 to arms 66 pivoted on pins 65 and provided with cams 64 engaging between the brake arms 41. As the roll 14 is used up the roll 48 acts continuously to adjust the tension of the belts 25 by means of the pulleys 59 and, periodically, and also when the press stops or the web breaks, it moves sufficiently far to the right to actuate the links 67 and cause the cams 64 to spread the arms 41 to allow the weight 33 to take up slack in the belts. The weight 33 may be controlled by a dashpot, and is also provided with a pinion 70 operable by a shaft 72 and engaging a rack 69 by means of which the weight may be raised to facilitate the introduction of new rolls. Web-roll supporting devices.-The roll 14 is carried by a pair of arms 10 fast on a shaft 21 to which is fixed a quadrant 15 operable by a worm 16 for raising and lowering the arms 10.

Abstract: 877,914. Welding by pressure. EMMCO DEVELOPMENT CORPORATION. July 9, 1958, No. 21995/58. Class 83 (4). Members to be percussion welded using the discharging current of a condenser connected between the members are provided with substantially parallel welding faces having small portions which make initial point contact. The ends of the members may be roughened as shown in Fig. 8 or inclined at less than 5 degrees. The voltage of the condenser does not exceed 450 V. A machine for welding wires 1 and 2, Figs. 1 and 2, has fixed and movable work clamps 3, 4 mounted on insulating blocks 9, 10 respectively carried by the base-plate 5 and a shaft 32 slidable in a sleeve 36 threaded in a block 37 in the base plate 5. The clamp 4 is urged towards the fixed clamp 3 by a spring 39 adjustable by the sleeve 36. Depression of a trigger connects the condenser across the wires 1, 2 and removes a spring-loaded detent 43 to allow the spring 39 to bring the wires into contact with a speed determined in part by an interchangeable weight 53 threaded on the rod. The clamps are parted by rotation of a cam 56 until the detent 43 is again interposed. In a modification a portable welding gun for welding a wire 102, Fig. 12, to the face of another workpiece has a movable clamp 104 holding the wire 102, and a support 103 adapted to be pressed against the other workpiece.

Abstract: Wire for grids of electric discharge apparatus is formed of an alloy containing 2.5-4.0 per cent Al, 2.5-20 per cent of Cr and/or Ti, the Ti proportion not exceeding 7.5 per cent, and the balance substantially pure Ni or Ni and Co, the proportion of Co not exceeding 20 per cent of the said balance, in which alloy the Al proportion is not greater than 5 per cent when the Ti is greater than 2.5 per cent.  The wire, after the wire drawing operation is strengthened by ageing in a non-oxidizing atmosphere at a temperature above 300 DEG C.  In an example an alloy containing 90 per cent Ni, 5 per cent Al and 5 per cent Cr is hot rolled, solution treated and quenched from about 1100 DEG C. to room temperature and then cold drawn.  The drawn wire is strand annealed by passing it through a furnace at 1000 DEG C. in dry hydrogen, quenched in air and then aged at 660 DEG C. in hydrogen for 1/2 hour.

Abstract: 1,070,074. Character recognition. HITACHI SEISAKUSHO KABUSHIKI KAISHA. May 29, 1964 [May 30, 1963], No. 22365/64. Heading G4R. A character is scanned by a plurality of scan lines to produce a pulse at each intersection with the character; the scan lines are divided into two groups A, B at LD (Fig. 3) and the numbers of pulses in each scan line are compared with those in adjacent scan lines EA to give an output signal a 5  . . . z 5  if these are different and these signals from the two groups are combined for recognition at RE. A line 2 (Fig. 1) below the characters sensed by phototransistors PT 2  determines the position of the centre line of the characters about which the scan lines are split into groups. Pulses from phototransistors PT 1  are amplified and shaped AM (Fig. 3) and then passed through flip-flops FF and differentiators DF to produce a zero signal from nought or one scan pulses and a one signal for two or more scan pulses (Figs. 4 and 5, not shown). A pulse from one of photo-transistors PT 2  inhibits central AND gates (Figs. 7A, 7B, not shown) to which signals n 3 , m 3  &c. are applied to split the scan lines into two groups about the central line for application to exclusive OR circuits EA, EB which compare signals in adjacent scan lines to give an output only if these are different (detail in Figs. 8A, 8B, 8C, not shown). The " 1 " outputs a 5  . . . z 5  from the exclusive OR circuits EA, EB are counted at CA, CB and introduced to a recognition circuit RE. Since 1, 7 and 0, 4 produce the same signals, the initial signals a 2  . . . Z 2  are applied to a long pulse detector LP (detail in Fig. 10, not shown) which gives an output signal γ for the 7 and 4. Signals a 2  . . . z 2  are also applied to an OR gate AD to produce a signal α indicating the start and finish of reading a character. In order to recognise a greater number of characters the binary signals may be split into more than two groups and a code employing 0, 1 and 2 may be employed. The photo-transistors may be replaced by magnetic heads.
