Title: Wave form equalizers
Inventor: KAWASHIMA MASAO
IPC: H03K5/06
Filed: 1963-11-17
Abstract: 1,119,261. Automatic equalization. FUJITSU Ltd. 17 Feb., 1965 [17 Nov., 1963], No. 22031/63. Heading H4R. An automatic equalization system uses a differentiated echo type equalizer and a frequency characteristic equalizer in combination, the frequency characteristic equalizer operating of the lower frequency components of the signal. Fig. 5 shows a system for equalizing a line 4 for the transmission of television video signals from a source 1. At the transmitter a synch. separator 2 synchronizes a pilot waveform generator 3 the output of which, e.g. a square wave, is added to the transmitted signal, outside the time or frequency band of the television signal, e.g. during the frame blanking period. At the receiver the signals are applied to the echo type equalizer which includes the tapped delay line DL from the tap Ao of which the signal is applied to the frequency characteristic equalizer LE before the differentiated outputs from the other taps of the delay line are added at the input of amplifier 12. The proportions of the outputs of the various taps of the delay line which are to be added to the output from tap Ao, and the constants of the frequency characteristic equalizer are determined by the automatic adjusting system in which a synchronizing circuit 5 causes generator 7 to produce an appropriately synchronized replica of the pilot wave form added to the television signal at the transmitter. The locally generated pilot waveform is compared with the received pilot waveform in differential amplifier DA and a difference signal is produced which is sampled in circuit S at times determined by the synchronizing circuit 5 and related to the delay in the tapped delay line DL. The sampled difference signal is then fed through gates G-m to Gt2, opened at times corresponding to the time of appearance of the pilot waveform at the delay line tap with which the gate is associated, to operate adjusting motors M-m to Mt2 which adjust the attenuators K-m to Kn on the delay line taps, and the values of the components of the equalizer LE, to tend to reduce the values of the sampled difference signal to zero.

Title: Improvements in fire control and gunlaying apparatus
IPC: F41G3/18
Filed: 1919-09-10
Abstract: 155,030. Pollen, A. H., and Argo Co. Sept. 10, 1919. Gyroscopic apparatus.-Relates to naval fire-control and gunlaying apparatus for use against targets invisible from the gun position, and consists in the employment of one or more datum lines gyroscopically fixed in space, in conjunction with range and bearing clocks. In the form shown, as applied to a turret, a gyroscope 2, driven electrically or by compressed air, is mounted in gimbals 3, 4 carried by a bracket 5 fixed to a casing 6 which is mounted in gimbals 7, 8 on pedestals 9 on the turret floor 1. Within the casing 6 is a ring 10, rotatable by hand or power, carrying a source of light 12, adapted to project a beam of light upon a mirror 13 carried by the gimbal ring 4, and thence upon the inside of the ring 10. The ring 10 is initially adjusted so that the spot of light 14 coincides with a lubber line 15 thereon. Any movement of the turret in azimuth will disturb this setting, which may be restored bv training the turret. The ring 10 may be rotated by hand, or by gearing from a motor controlled from a bearing clock, at a speed synchronous with the azimuthal speed of a. moving target or ship. By training the turret to maintain the coincidence of the spot 14 and the lubber line, the gun is made to follow the target in azimuth. A similar device is described for controlling the movements of the gun in elevation. It is stated that the apparatus may be employed at the fire-control or director position, instead of at each individual gun. Specification 11009/13 is referred to in the Provisional Specification.

Title: Improvements in or relating to presses for cementing or moulding the soles of boots and shoes applicable to analogous operations
IPC: A43D25/06
Filed: 1931-08-08
Abstract: 380,223. Boot-making machines. POCHIN, H. S., Croft House, Croft, Leicestershire, MILLMAN, C. H., Lamorran, Roundhill Road, and DOVE, G. H., 32, Hazelwood Road, both in Leicester. Aug. 8, 1931, No. 22509. [Class 17 (i).] Sole-laying and levelling.-Relates to multiple press apparatus of the kind in which a movable member carries a plurality of arms to each of which is pivoted a bridge-piece between which and an inflatable bag a shoe is clamped on its last during the operation, and consists in the provision of automatic means, operated by the movement of the member carrying the bridge, for both deflating the bag and releasing the bridge clamp so that the shoe may be readily removed. Preferably, the positioning of the bridge-piece for clamping and the inflation of the bag are also effected automatically, by the act of placing a shoe in position. A number of radial arms a<3> rotatable about an axis b each carry a number of dishes a each containing an inflatable bag e from which a pipe leads to a control valve k. Above each bag is a clamping bridge d on a pivoted lever d<1> spring or weight controlled to swing away from the bag but retained in operative position by a pawl f and ratchet i. The pawl has a handle h<1> for manual operation when desired, and a tail h co-operating with a cam g on a shaft L<2>. An arm k<2> on the same shaft co-operates with the handle of the valve k. A shaft l<2> is provided for each row of presses, each shaft carrying an arm l with a roll at its end co-operating with a fixed cam m, the arrangement being that as the presses carried by one pair of arms a<3> approach the operator's position, their bags are deflated and then their pawls f freed so that their bridges d rise to allow the shoes to be removed. Additional mechanism may be provided to position the bridges for clamping and re-inflate the bags automatically by the positioning of the new work-pieces. A pair of arms n are connected by a leather diaphragm n<3> above the bag, the free ends of the arms being linked to the bridge. The inner end of the lever d<1> co-operates with a stop o on a pivoted member adapted to engage a projection p4 on a collar g secured to the shaft l<2>. A second projection p<5> on this collar co-operates with the tail of the pawl f. An arm q<1> connected by a spring to the collar q engages an arm p<1> pivoted on the shaft l<2> and actuating the valve k. The arrangement is such that the new workpiece depresses the diaphragm n<3> bringing down the bridge d and tripping the member o<1> which releases the projection p<4> allowing the rod l<2> to be turned under the pull of the spring l<4> to engage the pawl f and lock the bridge and, thercafter, to reinflate the bag. In a modification, a plunger below the inflatable bag is connected to the lever d<1> by a lever and links.

Title: Improvements relating to sewing machines
IPC: D05B29/06
Filed: 1965-05-27
Abstract: 1,112,741. Sewing machines. GENERAL AUTOMATED MACHINERY CORPORATION. 27 May, 1965 [15 Feb., 1965], No. 22 547/65. Heading DIG. A sewing machine has a presser foot, thread tensioning and releasing means, a thread cutoff device, a needle positioner, and a driving motor controllable by a pedal. The machine is driven by depressing the forward edge of a pivoted treadle and stopped by releasing the treadle. If the rear edge of the treadle is then depressed, two microswitches MS1 and MS2 are closed. Current then flows via closed contacts 49, 50 and one of a pair of knee press-actuable microswitches 117 to energise a relay R<SP>1</SP> and solenoid valves 10 and D<SP>1</SP>. Relay R<SP>1</SP> then opens contacts in the circuits of solenoid valves A<SP>1</SP> and C<SP>1</SP>, valve 10 releases air pressure from one end of cylinders 9 and 24, and valve D<SP>1</SP> admits air to the other ends of cylinders 9, 24 for respectively releasing the break on the driving shaft and moving the piston rod 23 outwardly. Piston rod 23 thereby rotates the driving shaft via a slip clutch until a rotary cam 39 opens contacts, 49, 50 to de-energise relay R<SP>1</SP> and valves 10 and D'. Thereby, the brake, is applied, piston rod 23 moves inwardly, and a solenoid valve C<SP>1</SP> is energised via relay R<SP>1</SP> and a microswitch 65 to raise the presser foot with the needle fully lowered. If the microswitches 117 are actuated by the knee press while the rear edge of the treadle is depressed relay R<SP>1</SP> and the solenoid valves 10 and D<SP>1</SP> are energised via a pair of closed contacts 44, 45 and the main shaft rotates until cam 39 opens the contacts 44, 45 when the needle is in the fully-raised position. Solenoid valve A<SP>1</SP> thereby energised via the right hand microswitch 117, the closed contacts of relay R<SP>1</SP> and the closed contacts of a relay R<SP>2</SP>, to supply air to a cylinder 95 for moving apart a pair of thread-tensioning discs 95c, 95d, and to a cylinder 82 for moving the piston rod 81 inwardly against the bias of a spring 85. A block 68 on piston rod 81 thereby releases a lever 87 to allow closure of a thread clamp 90, and also allows microswitch 65 to open and microswitch 65a to close. During the movement of block 68, a pair of hooks 79, 80 thereon serve to draw off the thread between the tensioner and clamp. At the end of its inward movement, block 68 closes a microswitch 64, whereby a solenoid valve B<SP>1</SP> is energised to supply air to a cylinder 108 for actuating a thread-severing device 99, 100, and a relay R2 is energised for closing a holding circuit via the microswitch MS2 and for opening the contacts in the circuit of solenoid valve A<SP>1</SP>. The thread tension is thereby re-applied and piston rod 81 moves outwardly, when block 68 allows microswitch 64 to open and finally closes microswitch 65, whereby solenoid valve C<SP>1</SP> is energised to raise the presser foot.

Title: Digital data processing apparatus
IPC: G06F13/12
Filed: 1977-05-27
Abstract: 1521449 1/0 control INTERNATIONAL BUSINESS MACHINES CORP 27 May 1977 30 June 1976 22583/77 Heading G4A In an I/O system comprising a plurality of I/O processors (channels) each associated with a plurality of controllers having one or more attached devices requiring different microprograms for their control, the I/O processors are interconnected so that any of them may execute background portions of channel programs common to all devices and signal another I/O processor that background processing for a channel program specific to that other processor has been completed, and so that when the device-specific portion of the channel program has been executed by that other processor, the remaining processors can be signalled that background processing is required. Background processing may entail the fetching of channel command words (CCW) and the storage, as part of an ending sequence, of status words in main storage. Device oriented portions of a channel program are concerned with the execution of CCW's. Background and device-oriented processing are carried out in separate time slices which may be allocated in a fixed or variable sequence. Each I/O processor has a completion register 27 with a bit for each associated controller and sets the appropriate bit when it has completed a particular device-oriented portion of a channel program. A request for background processing is then broadcast to all the other I/O processors over line 24, this effectively taking priority over any similar request from the CPU over line 21. On receipt of a request for background processing, any non-busy I/O processor can allocate its background time slice to servicing of the request and, on completing the background processing, a bit corresponding to the relevant device controller is set in a request register 25 of the I/O processor which is needed to execute the subsequent device specific portion of the channel program. The output of the request register 25 presents a request for a device-specific microprogram to be executed to the associated I/O processor. Completion of an I/O operation is signalled back to the CPU on a line 19.

Title: Improvements in devices for following a movable object
IPC: G01S13/66
Filed: 1951-09-28
Abstract: 706,512. Rangefinders. ARENCO AKTIEBOLAG. Sept. 28, 1951 [Sept. 29, 1950], No. 22693/51. Class 97(1) [Also in Group XXI] A gun laying, rangefinder or other device for tracking moving objects includes tracking members which at any instant indicate the position of the object in polar co-ordinates by means of automatically acting members, such as shafts 5, 8, 9, driven by integrators 1, 2, 3, which are controlled by handles 10, 11, 12, the latter producing correcting quantities which are combined with data received from the tracking members in resolvers 16 17 which transform the correcting quantities into a stationary Euclidian system of co-ordinates. The transformed quantities are fed to the integrators and finally to devices 4, 7 which transform their inputs to polar co-ordinates and which actuate the shafts 5, 8. 9. In the construction shown the rotations of shafts 5, 8, 9 represent respectively rates of change in the azimuth angle # of the target, the, angle of elevation y and the range A. The quantities A, γ and # emerge from the co-ordinate transformers 4, 7 whose input shafts give the target's position in rectangular co-ordinates x, y, z; transformer 7 also receives an input A cos y from an output of transformer 4. Shafts x, y, z are rotated, to indicate the target's position continuously, by integrators 1, 2, 3, of the ball-carriage type, the balls of which are positioned to indicate the target's velocities x<SP>1</SP>, y<SP>1</SP>, z<SP>1</SP> in the corresponding planes. With the target correctly tracked and moving at constant speed the balls remain stationary. When an error in tracking is observed one or more of the handles 10, 11, 12, corresponding respectively to A', y<SP>1</SP>, #<SP>1</SP>, is moved until the target is tracked correctly. These handles operate tachometer generators 13, 14, 15 which produce output voltages proportional to the time derivates of the rotary movements of the handles, the voltages from the generators being modified, as shown, in potentiometers 30, 31 by inputs A and A cos y. The resulting voltages are supplied by leads 27, 28, 29 to the resolvers 16, 17, which also respectively receive γ and # data as shown, and which produce voltages in leads proportional to the corresponding correction data in rectangular, co-ordinates. These voltages are applied to circuits including amplifiers 21, 22, 23, motors 18, 19, 20 and tachometer generators 24, 25, 26, so combined that the motors rotate at a speed proportional to the voltage and thereby produce the required rotations x<SP>1</SP>, y<SP>1</SP>, z<SP>1</SP> serving to position the balls 1b, 2b, 3b of the integrators 1, 2, 3.
