Title: Electric circuits for carrying in, holding, processing and indication of the decimal point, especially in electronic calculators
IPC: G06F7/48
Filed: 1967-10-03
Abstract: 1,205,788. Matrix store; digital displays. ZENTRALEN INSTITUT PO ISTCHISLITELNA TECHNIKA. 3 Oct., 1967 [4 Oct., 1966], No. 44949/67. Headings G4C and G4H. Matrix store having a plurality of lines and columns holding a number whose binary digits are entered in columns and having an additional line for the storage of a decimal point, has associated circuits including read and write circuits and means for inserting a decimal point in the additional line at a column position corresponding to the lowest significant whole digit. A flip-flop circuit 8 initially in the zero state applies authorizing potentials to conditional differentiators 10, 11. These serve to differentiate an input signal when an authorizing potential is applied. With each digit applied to the store a one-shot multivibrator 7 sets flip-flop 9 to cause a " 1 " to be written in the decimal point row in the same column as the entered digit. The entered digit is read out and rewritten and after the read out a pulse via differentiator 11 prevents flip-flop 9 from rewriting the decimal point. This occurs for each digit until a decimal point key 13 is pressed. This sets flip-flop 8, prevents erasure of the entered decimal point and prevents the writing of further decimal points by inhibiting differentiators 10, 11. The circuit ensures a decimal point is not included behind the last digit in the event of a number having no decimal places being entered. If numbers are operated on, the circuit shown in Fig. 3 indicates the position of the resulting decimal point. A flip-flop 17 is set and a flip-flop 18 is reset to determine the direction of a reversible counter 19 by means of a circuit not shown and to trigger a monostable multivibrator 14 via differentiator 20. A multivibrator 15 receives signals from 14 and via differentiator 24 feeds signals back to cause generation of a series of pulses which pass through differentiators 22 or 23 to read one or the other of the numbers and through differentiator 27 authorized by flip-flop 17 to counter 19. When the decimal number is read, flip-flop 17 is reset, inhibiting the supply of pulses to the counter. On read-out the counter is reversed by setting flip-flop 18. During the reading of a number a " 1 " is added to the counter as each. digit is read. When the counter changes from a 1111 to a 0000 state a pulse is generated, setting flip-flop 9 and causing a " 1 " to be written in the decimal point line of an output register. The numbers can be displayed on decade counter tubes 33, Fig. 4, enabled by signals from amplifier 35, a neon bulb 34 for each digit stage being coupled to one terminal of the appropriate tube and to an amplifier 37 receiving a signal from the decimal point line.

Title: Pneumatic tube carrier system
IPC: B65G51/22
Filed: 1963-11-15
Abstract: 980,849. Pneumatic dispatch apparatus. STANDARD TELEPHONES & CABLES Ltd. (Standard Elektrik Lorenz A.G.). Nov. 15, 1963, No. 45230/63. Heading B8A. Apparatus for storage of empty pneumatic tube carriers comprises a tube loop D i , D 2 , Fig. 1, which receives carriers at E from the forwarding tube for storage in the lower loop part D 1  and which holds one or more carriers in the upper loop part D 2  in a position ready for despatch to a central position Z on demand. In the example of Fig. 1 a blower G 2  is connected at C 1 , C 2  between points B 1 , B 2  near the entry or exit ends of the loops D 1 , D2, the pressure and suction sides having controlled connections to atmosphere via normally open valves A 2 , A 3  by which both sides are disabled. Permanently open connections to atmosphere are provided at G 1  in tube E to permit escape of the conveying air from the main forwarding tube, and at A 1  at the junction between the loop parts D 1 , D 2  just above a one-way mechanical stop R h  for the carriers. In operation the empty carriers enter the loop part D 1  through a trip S 1  and are stored until there is a sufficient number to maintain the control switch K 1  permanently open whereupon further delivery is prevented. If there are no carriers present in the upper loop part D 2  valve A 3  is closed so that pressure is applied at B 1  in loop D 1  to convey the forwardmost carriers past the stop R h  to a trip switch K 2  whereupon the valve A 3  is re-opened leaving a stack of a predetermined number of carriers retained above the stop R h  while the remainder fall back in the loop D 1 . When empty carriers are demanded from one station the valve A 2  is closed, whereupon the stack of carriers is carried over the upper part of the loop D 2  and through an exit trip S 2 . A third trip switch K 3  engaged by the first carrier operates to re-open the valve A 2  so that the carriers are finally discharged by their own momentum. A fourth trip switch K 4  in the lower loop part D 1  operates in conjunction with the trip switch K 1  to control the valve A 3  whereby the loop part D 1  is completely filled with empty carriers between the two trip switches K 1 , K 4 . In a modification the blower G, Fig. 2, is connected on the suction side only via valves V 1 , V 3  for separate control of the conveyance of empty carriers through the loop parts D 1 , D 2  by suction only. Filter F i  and silencers S d  are arranged at various positions in the system and a safety cut-off valve V 4  is arranged to protect the blower G.

Title: A method of crushing and crushing apparatus therefor
IPC: B02C19/00
Filed: 1963-11-18
Abstract: 1,025,248. Crushing apparatus. ASSOCIATED PORTLAND CEMENT MANUFACTURERS Ltd. Nov. 18,1963 [May 19,1963], No. 45428/63. Heading B2A. Crushing apparatus comprises upright or substantially upright jaw plates 1, 2 pivotally suspended 3, Fig. 1, to permit of limited angular displacement about spaced horizontal axes, the space between the plates pivoting a crushing chamber 7, means 4 interconnecting the plates to move in unison, one or more rod-like crushing elements 8 carried by support bars 5, 6 extending across the crushing chamber, and means 10,11, Fig. 2, (not shown) for imparting a to-and-fro motion to the jaw plates. As described, the rod may be made of mild steel, manganese steel, chilled cast-iron, or as a concrete-filled tube. Material, e.g. cement clinker, is fed into the crusher in the direction of the arrow X. To dislodge adhering material a spring actuated hammer or magnetic vibrator may rap or vibrate one or both plates when they are in the open position. Drive may be applied at the lower end of the jaw plates, which may be pivoted at points between their ends. The pivot fulcrums 3 may be carried on blocks which are adjusted by screws towards or away from each other to vary the width of the crushing space, and by varying the lengths of the links 4 the angular relation of the jaw plates can be varied to suit operating conditions. Similarly the angular throw of the jaw plates and stroke of the driving mechanism may be adjusted. A number of crushing jaw units may be used, e.g. side by side operated from a common driving unit, Fig. 11 (not shown) or independently driven by connecting rods from a central drive, Fig. 12 (not shown). To permit increased flow of ground material the last stage or stages of a crusher may also be divided vertically by a plate 55, Fig. 13, (not shown) to form smaller chambers each having a single rod 56. The rod elements may increase or decrease in diameter in successive stages with one or more rods in each stage, and the jaw plates may be convergent or divergent in the direction of feed. A water spray may be introduced for coating purposes when grinding cement clinker. The separator-bars which divide off upper and lower rod compartments may be made floating in detachable bearing blocks.

Abstract: 986,327. Hydro-pneumatic suspension struts. ROBERT BOSCH G.m.b.H. Nov. 19, 1963 [Nov. 20, 1962], No.45555/63. Heading F2S. An hydro-pneumatic spring suspension strut 1 comprises an hydraulic shock absorber 2 and an air spring body 3 partly covering the shock absorber. A rolling membrane 10 seals the annular space between the air spring body 3 and a base cylinder 11, the base cylinder being mounted on the shock absorber and surrounding the same over part of its length. A chamber 11<SP>1</SP> is formed in the base cylinder and communicates through a narrow channel 19 directly surrounding the shock absorber with the interior of the air spring body. In the construction shown, the channel 19 is formed by a tube 18 which is sealed at its upper end against the base cylinder and is provided on its inner surface with individual projections 21, whereby it is centred on the outer wall of the shock absorber. The air spring communicates with the channel through an aperture 22 in the base cylinder. The air spring body is attached to the pistonrod of the hydraulic shock absorber. The movement of air through channel 19 due to the compression of the air spring acts to cool the hydraulic shock abosorber.

Abstract: 1303208 Feeding sheets BURROUGHS CORP 6 Oct 1971 [19 Oct 1970] 46405/71 Heading B8R In a document transporting apparatus, shown in plan in Fig. 1, in which an overlapping stream of documents is fed along a guideway 18, 14 into which a document feed means, e.g. a rubber coated wheel 80, protrudes for feeding separate sheets, a separator member 20 is provided for frictionally engaging the stream and allowing only single sheets to pass, the force with which the member is urged against the stream and the feed means being varied in response to the speed of the feed means, this speed being dependent upon the frictional force between the feed means, documents and separator member, such that a constant frictional force is applied to the documents under all conditions. Documents 10 on edge in a hopper 12 may be urged by a screw arrangement 42 to feed rollers 44 which feed an overlapping stream towards the wheel 80. A lever 62 actuating a switch 64 controls the screw 42, whilst a stripper wheel 74 prevents too many documents leaving the hopper at one time. A flexible, ridged, foam urethane belt 96, rotating in the opposite direction to, and slower than, the wheel 80, is urged against the stream as it passes the wheel 80 such that all the documents overlying the foremost document of the stream are held back by the frictional force applied thereto by the belt. This force also retards the speed of the wheel 80 to some extent, a slotted disc (88), Fig. 2 (not shown), and light sensor (90), (92) detecting this speed change and actuating a motor 116 which relieves the pressure of the belt on the documents and wheel thereby reducing the frictional force until an equilibrium is attained. Thus a constant frictional force is applied to documents by the belt irrespective of the changes in coefficient of friction of the documents, belt &c. The belt may be replaced by a wheel.

Abstract: 1,121,941. Control of D.C. motors; battery charging. GENERAL ELECTRIC CO. 2 Nov., 1965 [20 Nov., 1964], No. 46438/65. Headings H2H and H2J. The armature 2 of a D.C. motor is supplied from battery 4 through silicon controlled rectifiers 6 having a gating circuit 26 comprising a unijunction transistor oscillator whose frequency depends upon the rate of charging of capacitor 35. A transistor 36 is connected to the capacitor and is controlled by voltage divider 41 actuated by pedal 44. A quenching circuit for the rectifiers 6 comprises capacitor 24 associated with rectifier 12 and saturable transformer 20, 21, the pulses applied to armature 2 having a uniform duration but variable repetition rate. Inductor 53 maintains the armature current during the off-periods of the pulses. The armature current is detected by circuit 90 and used to control the excitation of shunt field winding 3. As the voltage across resistor 108 increases, transistor 91 is rendered more conductive than transistor 92 so reducing the current passed by transistor 114. Transistor 82 is rendered more conductive to charge capacitor 31 at a greater rate and fire unijunction transistor 70 more frequently. This increases the average current passing through rectifier 57 to the field winding 3. The rectifier 57 has a quenching circuit comprising capacitor 59 and saturable transformer 63, 64, overshoot of the capacitor voltage being prevented by diode 65 Regenerative braking operation is introduced when voltage divider 111 is set to reduce the current through transistor 92, so increasing the motor flux and providing regenerative charging of battery 4. Change-over of switches 125, 126, 127, causes the battery to be charged from source 130 through rectifier 129, the operation of circuits 5, 26, being the same as for motoring. If the charging current becomes excessive, diode 120 breaks down and biases transistor 122 to limit the charging rate of capacitor 35. The diode 120 also breaks down if the battery voltage becomes excessive. The motor is reversed by switch 143 energizing relay 146 or relay 147. Reversal is prevented if the motor speed is above a low value, the relays 146, 147 being interlocked and subjected to the back E.M.F. through diode 157.
Patent GB-464507-A (GB)
Abstract: 464,507. Accounting - machines. BREWER, G. (National Cash Register Co.) July 18, 1935, No. 20420. [Class 106 (i)] In an accounting-machine of the type described for example in Specifications 387,032 and 368,117 and having a mode of operation lever to which is allotted a special supplementary or correction position in which the engagement of all totalizers except the balance mechanism is prevented, the mode of operation lever becomes locked when set to the supplementary or correction position but is released at a stage in the ensuing series of operations when it is no longer necessary to ensure non-engagement of the totalizers, for example in a new balance operation. When an incorrect entry is discovered, it is manually cancelled on the customer's account sheet, the correct entry is made and the incorrect entry repeated on a correction sheet. This last entry is effected with the mode of operation lever in its special position, and at the end of the day the items on the correction sheet are subtracted from the amounts standing in the corresponding totalizers. If this is effected by complementary addition, a normally locked bank of amount keys corresponding to the overflow wheel of each totalizer must first be released by an insertable key. In order that the mode of operation lever 5. should not be moved out of its special position during a correction series of operations, a stud 43 on the lever co-operates with a detent 42 pivoted on a shaft 38. During an operation involving the taking of a new balance, the operation lever is returned automatically to adding position by mechanism of the kind described in Specification 393,256, means being provided to disable the detent 42 at this time. Towards the end of each machine operation, a lever 114 pivoted on the shaft 38 receives a counterclockwise rocking from a cam 102. This rocking movement is normally idle, but upon the adjustment of the balance lever to total-taking position, a stud 106 is moved into the path of the lever and the rocking transmitted to a pitman 36. Movement of the pitman, through a lever 112 and stud 107, returns the operation lever and, through levers 37, 39 and a link, disables the detent 42. In machines having no new balance totalizer, the release mechanism for the operation lever may become operative during the item-entering operation.
