Patent GB-404927-A (GB)
Abstract: 404,927. Calculating-machines. ELLIS ADDING-TYPEWRITER CO., 338, Elizabeth Avenue, Newark, New Jersey, U.S.A. April 22, 1932, No. 11586. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 23, 1932]. [Class 106 (i).] In a calculating-machine having two adding and subtracting totalizers as well as two adding totalizers, the various totalizers are selected by stops 2 on a paper carriage 1 co-operating with a series of levers 3 .. 8. The invention is shown applied to a machine of the Ellis type described in Specification 28253/08, [Class 106, Registering &c.]. Levers 3 and 4 control the two adding totalizers, levers 5 and 6 control the two adding and subtracting totalizers for addition and levers 7 and 8 control them for subtraction. The operation of the lever 8 rocks a lever 12, Fig. 4, connected by a link 13 to a lever 14, which is thus moved clockwise. A link 21 is thereupon moved to the left to set the totalizer for subtractive operation and a blocking piece 18 is moved under a pin 19 of the total key 20 of that totalizer, to prevent the depression thereof. The operation of the lever 7 in a similar manner sets the other totalizer for subtraction through a link 24. This setting can also be effected by a key 26. When the left-hand totalizer passes into an overdrawn condition, a link 28 moves to the left and inserts a projection 31 into a notch 32 in the stem of the corresponding total key 20, which is thus locked. Specification 395,688 also is referred to.

Title: Electric feedback measurement apparatus
IPC: H03M1/48
Filed: 1972-09-01
Abstract: 1400559 Self balancing A/D converters METRIPOND MERLEGGYAR 1 Sept 1972 [2 Sept 1971] 40534/72 Heading H3H An A/D converter of the type where an analog voltage is balanced by a reference analog signal, the variation of this reference being dependent upon the input voltage is adapted so that a fast measuring time may be achieved and that errors inherent in the fast switching of the feedback loop reduced. As shown a converter having two feedback loops is provided. The voltage to be measured is applied as one input to a difference circuit, the other input being supplied by a D/A converter 10 of the type adapted to provide an analog output from a series of input pulses. This difference is amplified at 9 and passed as input to a second difference circuit 1, the other input of this being the output of a second D/A converter 5 of similar type but capable of much faster response time. This second difference is amplified at 2 and applied to a gate 3 having also a fast clock input 4, whereby the gate passes pulses to its output, the number per unit time being dependent on the output from amplifier 2. These pulses A are counted at 6 and used as input to the D/A converter 5 and as one input to an array of AND gates, Fig. 4 (not shown), of an input circuit of an impulse divider 11, the other input B being those pulses not passed by the gate 3. The divided pulse series is fed as input to the D/A converter 10. Thus the measurement time is dependent on the speed of the fast clock 4 and the errors at 5 are reduced by the gain of amplifier 9.

Abstract: 1,115,167. Multi-platen presses. G. SIEMPELKAMP & CO. 12 Sept., 1966 [7 Oct., 1965], No. 40604/66. Heading B5F. In a multi-platen press comprising a series of platens 4 connected by locating elements 6 to a control lever 5 which is pivoted to a fixed beam 2 and to an actuating rod 5A itself pivoted to a moving beam 1, the control lever 5 is fitted with a force equalizing device. In one example (Fig. 1, not shown), this device comprises a series of cylinder and piston units (7) connected individually to the various locating elements 6. The cylinders are pivotally mounted on the lever 5 and have their lower compartments filled with hydraulic fluid and connected together and to an air-cushion device (8) to give resilience. In Fig. 2, the force equalizing device comprises a cable 10 passing over two sets of rollers, one set 9 being mounted on the lever 5 and the other set 11 on the head ends of the elements 6. The tension in the cable 10 is adjustable by screws 12. The rollers 9 and/or 11 may be braked by brake pads 14b carried by brackets 14a on a braking bar 14. This bar may be operated by compressed air and hydraulic pressure or by springs. The elements 6 may be cables and include turn-buckles 13.

Abstract: 1,132,637. Elastomer springs. RENAK WERKE VEB. 13 Sept., 1966, No. 40820/66. Heading F2S. A shock-absorber leg for a motor cycle comprises a hollow body 4 of plastics or resilient material wherein the ratio of the largest outer diameter D of the spring to the smallest inner diameter d thereof is from 2À0 to 3À5 and the ratio of the spring length l to the smallest inner diameter d is from 2À0 to 8À0, a cylindrical or conical end of the hollow body engaging in a frusto-conical recess 3 of a support member 2 and being held by the conical lateral surfaces of the recess 3 during compression of the body. The upper region 6 of the spring body 4 is a sliding fit on a piston-rod 7 of the shockabsorber, the remaining length of the body 4 being spaced from the rod 7 by a clearance 8. The lower end of the body may also slidingly fit the rod 7 and the whole of the body may be of frusto-conical shape.

Title: A method of treating liquids
IPC: B01D33/00
Filed: 1963-10-16
Abstract: <PICT:1012506/C1/1> <PICT:1012506/C1/2> In operation of a contacting vessel, the valve 7 is closed and the inlet valve 11 is opened and discrete particles of a treating material 12 are introduced under pressure through the inlet pipe 9 until the tank is filled with compacted material to the level of the retaining screen 8. In the tank shown in Fig. 1, the portion of the bed located above the distributer 2 will tend to become more compacted than the portion disposed below, but in Fig. 3 the entire bed will become compacted substantially uniformly throughout.  The valve 11 is now closed and an untreated liquid is fed under a predetermined pressure and in a predetermined volume into the bed.  As the content of the liquid in the tank increases, it will pass through the bed and exit in the form of a purified effluent through the retaining screen 8 into the collecting chamber 13 and through the product outlet pipe 14.  After a sufficient period of time, the bed 12 tends to become spent or exhausted with the material near the bottom of the column showing the greatest degree of exhaustion.  To replenish the material, outlet valve 7 of Fig. 1 or outlet valve 18 of Fig. 3 and inlet valve 11 are opened simultaneously and fresh material is introduced under pressure through the inlet pipe 9 so as to simultaneously force the most exhausted material out through resin outlet pipe.  It is important that the fresh material be introduced at a sufficient rate so that the exhausted material is forced out of the bed rather than allowed to drop by gravity so that the bed is maintained in its original compacted condition. The force pushing the absorbent through the tank may be varied and controlled by the inlet and outlet valves. Specification 1,012,507 is referred to.

Title: Telephone switching systems
IPC: H04Q3/62
Filed: 1961-11-16
Abstract: 917,939. Automatic exchange systems. WESTERN ELECTRIC CO.. Inc. Nov. 16,1961 [Nov. 29, 1960], No. 40991/61. Class 40 (4). In a private branch exchange in which the switch train is held by ground applied to the sleeve wire at the final selector, the attendant on receiving busy tone may connect positive battery to the sleeve wire to operate a camping relay which removes the busy tone, the wanted line being run when it becomes idle. It is assumed that calls incoming to the P.B.X. are supervised by the attendant. The bidirectional final selector shown is adapted for rotary hunting, the S (test) and H terminals of all lines of a group except the last being strapped together. The selector is set in response to two trains of impulses to the first line of the wanted group, and if that is busy test relay H energizes, whereupon relay G pulls up and interacts with rotary magnet 27 to step over the group. If an idle line is found, H goes back, K energizes to battery on the S terminal and ringing and switch-through take place. If the last line is busy, H remains up but G cannot re-operate so that busy relay J, previously short-circuited, operates and returns busy tone. The attendant may now operate a key 73 to apply positive battery to sleeve wire 17 to energize camping relay Z. This battery is isolated from the ground provided by relay B by diodes 16, 76. If no other selector is camped on the line, relay J falls back, removing busy tone and connecting resistance battery to the H terminal. This prevents any other selector camping by holding its relay J. When the line becomes idle H falls back and the call is completed.
