Title: Improvements in keyboard and differential mechanism for cash registers, and other calculating machines
IPC: G06C7/10
Filed: 1924-08-25
Abstract: 243,083. Gill, H. A., (Registrier- Maschinen R÷der Akt.-Ges.). Aug. 25, 1924. Keyboards; differential-mechanism. - A mul. t'iple-bank keyboard and differential mechanism for a cash register or calculating machine is of unitary construction each unit comprising a bank of keys and a differential mechanism mounted upon a frame 3 traversed by the main driving shaft 14 given a rotation alternately :n opposite directions at each operation of the machine. The differential mechanism consists of two racks 11, 12 the first of which has a constant excursion derived from the main shaft and actuates the other through a pawl 18 disengageable by the action of a depressed key. The rack 11 is attached to a carriage 10 mounted in the frame by means of rollers and carrying a pivoted lever 20 provided with a one-way pawl 23 slotted to co-operate with pivoted stops 22 any one of which may be held rigid by the lowered end of an arm 6 fixed to a key. The pawl 18 pivotally mounted on the carriage has a wedge-shaped nose to engage a notch in the rack 12 and also has a pin 19 cooperating with a lug 21 on the lever 20. Depression of a key prevents one of the stops 22 from yielding to the passage of the pawl 23 and also by endwise displacement of a detent bar 7 rocks an arm 27 to the left to effect through a pawl 25 a counterclockwise movement of the lever 20 to free the pawl 18. Consequently this pawl falls into engagement with the differential rack 12 and is locked therein by the return of the lever arm 27 under the spring action of the detent bar 7. Operation of the main shaft now produces movement of the two racks until by engagement of pawl 23 with the locked stop 22 the lever 20 is tilted backwardly to free the pawl 23 and so disconnect the racks. At the end of the outward journey the lever 20 is restored to upright position by meeting a spring stop 36 and the detent bar 7 is shifted to release the depressed key by means of a lever 32 and pin 34. In the return journey the rack 11 positively returns the rack 12 by direct engagement at 16. To rectify an incorrect setting an error key 31 is depressed to t'ilt the lever 20 counterclockwise and through pawl 25 and arm 27 displace the detent bar 7 to allow the digit key to return. The rack 12 actuates the printing adding and indicating devices through wheels such as 37 and 53 arranged one behind another as shown.

Patent GB-836332-A (GB)
Title: Novel amino-acid hydrazides and a process for the manufacture of same
Filed: 1958-06-24
Abstract: The invention comprises amino-acid hydrazides of formula <FORM:0836332/IV (b)/1> where R1 is an aralkyl radical or a C1-7, alicyclic or aliphatic hydrocarbon radical, R2 is hydrogen or a hydrocarbon radical which may contain oxygen, nitrogen and/or sulphur atoms, R3 is hydrogen or alkyl and R4 is hydrogen, alkyl or acyl and R2 and R3 and R4 may be linked to form a heterocyclic ring, and salts thereof.  A list of salt-forming acids includes ascorbic acid. Preparative methods specified are: (1) reaction of amino-acids with substituted hydrazines in the presence of a carbodiimide, e.g. at room temperature or slightly above, conveniently in aqueous or organic solution; (ii) reacting a reactive amino-acid derivative such as the ester, halide, amide or anhydride with a substituted hydrazine, preferably by heating a mixture under reflux; (iii) heating the substituted-hydrazine salts of the amino-acids to a temperature at which the salts dehydrate, advantageously removing the water formed continuously; (iv) reacting an amino-acid hydrazide with a carbonyl compound and reducing the resulting hydrazone simultaneously or successively e.g. by hydrogenation or with lithium aluminium hydride or by treating the hydrazone with a Grignard reagent and and hydrolysing the resulting product.  In the above processes the group R4 may be chosen as an acyl group which is readily removable by alkaline hydrolysis (e.g. trifluoroacetyl) or hydrogenolysis (e.g. carbobenzyloxy).  The products act as amine oxidase inhibitors and have therapeutic uses.  Starting materials prepared are: in Example 11, DL-allo-carbobenzyloxythreonine and in Example 19, DL-threo-N-carbobenzyloxy-b -phenylserine by carbobenzyloxylation of the corresponding amino-acids; in Example 22, DL-a -dimethylamino propionic acid, which is converted to its ethyl ester, by reacting a -bromopropionic acid with dimethylamine; in Example 23, DL-a -methylaminopropionic acid and its methyl ester are similarly prepared using methylamine.

Title: Remote control device for an automatic telephone answering apparatus
IPC: H04M1/652
Filed: 1972-05-01
Abstract: 1385069 Substation apparatus PIONEER ELECTRONIC CORP 1 May 1972 [30 April 1971] 20227/72 Heading H4K A telephone answering machine is adapted in response to an interrogation signal received from a remote location, to replay only those of the messages recorded in response to incoming calls that were received since the last interrogation. As described the machine has a closed loop announcement tape driven by a first drive motor at the start of each call and a message tape driven in forward or reverse direction depending on whether a first solenoid is energized or not. Two counters are provided each driven in the forward or reverse direction whenever the tape moves in that direction. Each counter has an associated solenoid which when energized resets that counter to zero and an associated contact which it sets in one state when its count is positive and in the other state when the count is negative. At the end of each interrogation operation both counters read zero. As subsequent messages are recorded the counters are advanced simultaneously. When an interrogation signal (a predetermined frequency transmitted by a caller) is received one counter is reset, the first solenoid is deenergized and the message tape drive motor activated driving the tape in the reverse direction. When the other counter passes through zero it switches its contact disabling a relay re-energizing the first solenoid causing the tape to be driven in the forward direction. When the messages have been replayed the said one counter passes through zero operating its contact to de-energize another relay which returns the apparatus to the standby condition and connects a charged capacitor to the solenoid associated with the other counter resetting the same. Thus both counters are reading zero ready for further recording and interrogation.

Title: Improvements in or relating to hydraulic change speed gears
IPC: F16H39/14
Filed: 1923-08-08
Abstract: 202,309. Brunner, H. Aug. 8, 1923. Cam-actuated pumps ; stroke, varying.-Relates to hydraulic change-speed gears of the type comprising two sets of pumps and swash-plates, eccentrics &c., and consists in a construction whereby leakage is made up from a central chamber connected by stationary piping to an oil reserve exposed to the action of stronger centrifugal force. The gear shown in Fig. 1 comprises a driving shaft 1 carrying a casing 3, 4 with central plate 5, a driven shaft 2 carrying a cylinder block 7 pressed against the plate 5 by a spring 21, the pistons being connected to adjustable socket rings 132, 32. The plate 5 has opposite arcuate slots 49, Fig. 4, and two leakagereplenishing valves 53, Fig. 6, each with connected flaps 56 controlling communication between a central chamber 29 and the slots 49. Pipes 30 extend from ports 28 in the cylinder block 107 and are directed in opposition to the motion of the liquid in the revolving casing whereby the chamber 29 is kept constantly filled, so that liquid may pass therefrom under the action of centrifugal force through the passage 54 in the valves 53 and the ports 55, 52 to the slots 49 to make up leakage. The valves may be fitted with filters, and are readily removed from the exterior of the casing. Ports 22 extend from the cylinders 106, so that excessive pressure is relieved by a sleeve valve 23 lifting against its spring 24, or by manual rotation of the valve which has apertures adapted to register with the ports 22. The Specification as open to inspection under Sect. 91 (3) (a) comprises also statements that a direct mechanical drive may be obtained by engaging teeth 16 on the block 7 with teeth 17 on the casing by endwise motion of the driven shaft, a smaller motion lifting the block off its seat and stopping the driven shaft, and that the socket ring 132 may be adjusted automatically from a governor on the driving or driven shaft, or from a plunger controlled by the pressure in the cylinders 106, and contains also a more detailed description of the gear. According to this description, the block 7 is carried by a collar 10 having sliding engagement with keys 11 on a shaft 12, to which the socket ring 32 is univereally jointed. The ring 32 is mounted by balls 59, 60 in a spherical member 35 bearing on guides 36, 37 and capable of angular adjustment by a link 39 and screw 38. The casing drives by opposite internal radial pivots a member 135 supporting by balls 159, 160 the socket ring 132 universally jointed to the sleeve 19. The member 135 is adjustable by a link 46 from a sleeve firmly embracing a nut 44 prevented from rotating by pin 43 and adjustable by a nut 41 on a sleeve 47 fitted with an operating member 42. This subject-matter does not appear in the Specification as accepted.

Abstract: 862,966. Films. DOW CHEMICAL CO. June 28, 1957 [July 11, 1956], No. 20471/57. Class 2(2). Films are made from polystyrene, polyvinyltoluene, or copolymers of styrene or vinyl toluene with one another or with alphamethylstyrene or acrylonitrile by supplying the polymer in homogeneously molten condition at from 170-200 C. and advancing it toward a downwardly directed tube-forming extrusion orifice having a vertical axis, cooling it during its advance and extruding it in tubular form through the orifice at a constant lower temperature of 130C. to 170C., conducting the extruded tube downwardly through a non-reactive gaseous atmosphere at a temperature at least 40 C. below the heat-distortion point of the polymer and thence through the nip of a pair of horizontally disposed pinch rolls, maintaining an air bubble trapped within the tube between the pinch rolls and the extrusion orifice under a small but positive superatmospheric pressure, of sufficient volume to stretch the tube radially to the desired extent before it is cooled below its heat distortion temperature, and driving the pinch rolls at a peripheral speed greater than the linear rate of extrusion of the tube to effect about as much longitudinal stretching in the hot tube as the amount of radial stretching effected by the entrapped air bubble. Preferably the polymer is cooled to a constant temperature in the range 140-155C. just prior to extrusion, and the non-reactive gaseous atmosphere is still air. As shown, the polymer tube may be passed through a guide ring, concentric with and larger than the orifice but smaller than the ultimate diameter of the inflated tube, positioned beneath the orifice to fit slidably about the moving tube. The guide ring may be internally cooled. A suitable guide ring is disclosed in Specification 862,967. The inflated film may, as shown, be collapsed by two converging banks of horizontal guide rolls, and radiant or convected heat may be applied to the tube over the area nearest the pinch rolls, to remove wrinkles.

IPC: D06N7/00
Filed: 1929-07-08
Abstract: 336,277. L'Estrange, W. O. July 8, 1929. Mosaic and inlaid linoleum.-Inlaid tiling or linoleum is made by means of a machine having a table supporting electrically operated cutters and depositors which moves with a reciprocating motion alternately over the materials to be cut and the point of assembly. The machine comprises a table A, Fig. 2, to which are bolted slides B travelling on machined frames C having grooves V which form guides for the slides B. Lubricators are provided on the latter. The frames C are supported on staunchions D, Fig. 1, braced by cross girders E and longitudinal members F. A plate G supports a sheet of lead H on which the tesserae are cut from lengths 7 of rubber or other material. Electrically operated cutters M and depositors N, the construction of which is described in Specification 336,224, [Class 31 (i), Cutting and severing machines &c.], are suspended below the table A, which is provided with slots J, and with T-slots K by means of which they are secured to the table in the desired positions. Carried on an extension of the table A on one side is a variable speed reversing motor and a controller, and on an extension on the other side the control gear for operating the cutters and depositors. This consists of fixed contacts which make contact with fingers disposed on a rotating spindle, the position of the fingers being adjustable to operate the cutters and depositors at any position of the travel of the carriage. The shaft R, Fig. 2, is driven from the motor through spur gearing O, and is provided with pinions S at each end which engage with racks T on the side frames C. Control of the speed, and reversal of the motor is effected by a variable voltage armature control. A gear U on the shaft R transmits motion to the motor control gear which is connected to bushes on an arm 8. A shaft W at the other end of the carriage is driven by pinions X engaging the racks, and transmits motion through gears Q to the control gear of the cutters, which is connected to brushes on an arm 9. The brushes on the arms 8 and 9 make contact with bars L. The backing material 2, Fig. 1, passes over a brush 4 which applies an adhesive solution, and is drawn through by rollers 5. The cutters and depositors are assembled on the table A in accordance with the pattern to be produced, and the control gear set to give the desired sequence of operation. The carriage travels to and fro between the points Y and Z, and as it passes over the rubber or other material 7, the cutters are momentarily operated by the control gear, so that each cutter picks up a tessera of the required colour. As the carriage passes over the backing material 2, the depositors are operated by the control gear and the tesserae are deposited. The material then passes between rollers 6, and is then vulcanized or otherwise treated as required.
