Title: Improvements in or relating to calculating machines, accounting machines and similarmachines
IPC: G06C21/04
Filed: 1934-08-07
Abstract: 442,443. Calculating-apparatus. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A. Aug. 7, 1934, No. 22826. Convention date, Nov. 1, 1933. [Class 106 (i)] A calculating-machine having an adding and subtracting totalizer, a total key, and a subtotal key normally used in conjunction with the total key for taking a sub-total, the total key being locked upon the occurrence of an overdraft in the totalizer, is provided with means operated upon the depression of the sub-total key to disable the locking means for the total key. The invention is shown applied to a machine of the Ellis type as described in Specifications 28253 /08, [Class 106], and 241,983, [Class 106 (i)], comprising the usual operating plate 12 with flying lever 14 controlling the engagement of the totalizer with the actuating racks 27. When the total key 29 is depressed, a latch 31 rocks so that a pin 32 moves the total-taking cams 36, 37 into the path of the flying lever 14. The total key 29 is released upon the anticlockwise or return movement of the plate 12 by a stud 28 which tends to rock clockwise a lever 45 pivoted to a release bar 38. The upper end of the lever 45 engages a pin 47 whereby the bar 38 is moved to the left so that its lug 48 releases the latch 31. During its first or clockwise movement the plate 12 turns anticlockwise a lever 43 pivoted at 42 whereby a bar 53 is moved to the left. To take a sub-total, the total key 29 and the sub-total key 49 are both depressed. The latter key inserts member 51 between a pin 52 on the bar 38 and a pin 57 on the bar 53. The bar 38 is thus moved to the left with the bar 53 to release the total key and so remove the cam 37 from the path of the lever 14 to allow the taking of a sub-total. If an overdraft occurs, a shaft 58 rocks anticlockwise to insert a latch 64 into the jaw of a lever 65 pivoted to the total-key stem and normally held by a spring in the position shown in Fig. 1, the total key thus being locked. When the sub-total key 49 is depressed, a link 67 is moved to the left, a projection 70 on the link rocking the lever 65 by means of a pin 71 to remove the jaw from locking engagement with the latch 64 so that the total key 29 can be depressed.

Title: Apparatus for determining a reference direction, such as the direction of north
IPC: G01C19/66
Filed: 1969-05-05
Abstract: 1,255,836. Direction finding. COMPAGNIE GENERAL D'ELECTRICITE. 5 May, 1969 [7 May, 1968], No. 22847/69. Heading H4D. Specification describes a ring laser gyrocompass wherein the laser is mounted on a rotating platform and the platform is aligned such that the frequency component in the beat frequency output of the laser due to the rotation of the Earth is reduced to a minimum, the resulting alignment being indicative of geographical North.  The ring laser 1 is rotated at rate # on platform 2 about an axis 3 passing through its plane whereby no resultant beat frequency component is produced in its output 11<SP>1</SP>. Due to the rotation of the Earth however with a rotational vector ##, making an angle # with the unit vector n normal to the plane of the laser, the beat frequency output of the laser is frequency modulated at a rate If the projection of vector ## (parallel to the Earth's axis) on platform 2 is #N (indicating the North direction), the direction of the plane of structure 5 is N 0 , the angle between #N and N 0  is # and the instantaneous angle between #n and No is α and the angle between vectors #N and ## is #, then The arrangement thus seeks to measure p, and align support 5 by means of motor 10 until the plane of said support is aligned with North, i.e. # = 0. The angle α is digitally determined by rotating indices 16, 17 co-operating with pick-up means 14, 15, to produce signals representing B. Sin a and B. Cos α from means 13 and 13<SP>1</SP> respectively. A signal A. Cos (α - #) is produced from the beat frequency by demodulator 12. Summing means 20 and 20<SP>1</SP> receive the above signals and by analoging the functions produce signals K. Sin # and K Cos # respectively. These are divided in means 24 to produce a signal tan #, which is used to control motor 10.

Title: Biochemical synthesis or degradation using entrapped enzymes
IPC: A61K9/50
Filed: 1974-05-22
Abstract: 1474418 Cellular membranes KERNFORSCHUNGSANLAGE JULICH GmbH 22 May 1974 [23 May 1973] 22965/74 Heading B1X [Also in Divisions C2 and C3] Vesicles with semi-permeable membrane walls are obtained from cells of an organism, e.g. erythrocytes, and used as carriers for enzymes. The enzyme is foreign to the cell and is inserted into the vesicle by osmosis from a solution having a lower osmolarity than the cell contents. The entrapped enzyme may then be used to carry out biochemical synthesis or degradation reactions involving the enzyme by treating solutions of the starting materials having osmolarities sufficiently similar as to maintain the cell membrane impermeable to the enzyme, whereby the starting matterials may diffuse through the membrane, undergo reaction, and the products then diffuse out. In the example invertase is entrapped and used to convert cane sugar to glucose and fructose.

Title: Improvements in electric signalling systems incorporating wave-guide connections
IPC: H01P1/161
Filed: 1946-08-02
Abstract: 635,760. Wave-guides. GENERAL ELECTRIC CO., Ltd., LAMONT, H. R. L., and ROBERTSHAW, R. G. Aug. 2, 1946, No. 23144. [Class 40 (viii)] In an electric signalling system, the signals associated with each of two contiguous stations are given different polarizations, and the common wave-guide connecting the stations to a common transmission channel is adapted to separate the signals of different polarizations. Two stations, 6, 7, Fig. 1, which may be a transmitter and receiver, respectively, are connected to a flared horn aerial 1 through a wave-guide 3 with branch arms 4, 5. The guide 3 and branches 4, 5 may be circular in cross-section, and polarization filters 8, 9 in the form of slotted diaphragms are placed in the branch arms. The distance between the junction and the polarization filter in either branch is made an odd or even multiple of quarter wavelengths according as the branch presents a shunt or series impedance to energy flowing in the other branch. An impedance matching diaphragm 10 may be provided at the junction of the main guide and branch arms. In another embodiment, Fig. 3, the main guide 3 is of square cross-section, and the branch arms 4, 5 are of rectangular crosssection, each transmitting only waves polarized parallel to its short sides. The branch guides, are arranged to present parallel impedances to the main guide 3, which is continued for an odd number of quarter wavelengths, and closed at this end. In a modification, the branch guides are arranged to present series impedances to the main guide, which is continued for an even number of quarter wavelengths. The branch guides may be reduced to slots. In a further modification, Fig. 7, one branch guide 4 is arranged to present a series impedance to the main guide 3 and is situated an even number of quarter wavelengths from the closed end 14 of the guide, while the other branch 5 presents a parallel impedance to the main guide 3 and is an odd number of quarter wavelengths from the closed end 14. The arrangement may be used at the terminal of a duplex radio-signalling link. The frequencies used in different directions may differ, and the receiver may be superheterodyne, the transmitter providing local oscillations. Specification 582,176 is referred to.

Abstract: 480,689. Flushing-valves. DREYER, F. L., and BROMLEY, C. Aug. 24, 1936, No. 23264. [Class 135] A flushing - valve for closets and the like is adapted for direct connection to a supply main 8 and comprises a casing 1 divided by a partition 2 into an upper chamber 3, communicating with the flush pipe 6, and a lower piston chamber 4. A piston 5 works in the chamber 4 and has a piston rod 10 carrying a main valve member 9 and a second valve member 11 adapted to seat on the upper and lower sides respectively of an aperture 7 between the main 8 and chamber 3. A control valve 14 actuated by, for example, a treadplate 23 controls the pressure from the main 8 through a conduit 17 to raise the piston 5 and move the valve 11 to seat on the underside of aperture 7. On release of the valve 14 it closes under the water pressure and relief orifices 21 are opened by the valve head 20 to allow the water to leak out of the space below the piston 5, which moves down under the water pressure to open the aperture 7 for the flush, which continues until the main valve member 9 seats on top of the aperture 7. The size of the relief orifices determines the time the piston 5 takes to move from its upper to its lower position and hence the duration of the flush. An air escape passage 13 for the space above piston 5 is provided, and one or more relief orifices may be provided in the wall of the cylinder near the lower end thereof so that the piston will be subjected to a retarding or dashpot action as the main valve member 9 approaches its seat.

Title: Oscillation generator
IPC: H03C3/26
Filed: 1944-11-23
Abstract: 586,584. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 23, 1944, No. 23353. Convention date, Nov. 24, 1943. [Class 40 (v)] A crystal controlled oscillation generator, comprises one or more valves associated with a crystal, either directly or through an impedance inverting network, or alternatively through part of the network. The Figure shows an oscillation generator which may be frequency modulated. Valve 12 tends to oscillate at the frequency of maximum crystal impedance, while valve 10 tends to oscillate at the frequency of minimum crystal impedance, as its grid is connected to the crystal through the impedance inverting network L, C1, C2. The actual frequency at which the system oscillates depends on the individual gain of the valves 10 and 12, so that the oscillator may be tuned between the limits indicated above, by differentially varying the valve screen potentials by means of the ganged potentiometers 40, 42. Frequency modulation is effected by feeding the 'valve screens in a push-pull manner. The frequency of maximum crystal impedance, and hence the frequency range, may be varied by altering the detuning of the resonant circuit L, C3, C3, including crystal holder capacitance. Feedback to sustain oscillation is provided by the capacitors C and C<1>. In a modification. Fig. 2 (not shown), the crystal and tuned circuit are connected to the grid of a single valve through part or all of a network, tuning being effected by varying the point at which the valve grid is connected to the network.

Patent GB-236235-A (GB)
Abstract: 236,235. National Cash Register Co., (Assignees of Shipley, B. M.). June 30, 1924, [Convention date]. Cash drawer mechanism.-The selection for release of one of a number of drawers is effected by the depression of a key in anv one of a number of control banks. In the form shown as applied to machines of the kind described in Specifications 8119/15 and 176,781, there are three such banks and nine drawers and the control as to two of the banks is exercised through a common device. The differential mechanism of one bank is connected with a rack 57 engaging a loose pinion 60 driving through a sleeve 98 and spiral gears 99, 100 a vertical spindle 104 carrying helically disposed lugs 105' and capable of up-and-down motion independent of the gear 100. A similar spindle 108 is controlled by a shaft 61 provided with a pinion 79 engaged by a rack 78 attached to a rod 73 capable of sliding in guide slots 74 formed in two rackbars 69, 70 geared with the differential mechanisms of the two other control banks. These rack-bars respectively have teeth 71, 75 meshing with pinions fixed to the rod 73 so that the rack 78 slides forward or backward with the differential movement derived from depression of a key in either bank and produces a corresponding selective rotation of the spindle 108. One or other of these spindles 104, 108 having been thus set to bring a lug 105 or 109 below a projection 123 or 122 on a releasing bar 124 for the drawer required, the subsequent operation of the machine effects the rocking of a shaft having forked arms engaging the spindles so that these rise and one of them lifts the lever 124 and through a lever 106 depresses the latch 92 to free the drawer.
