Title: Intermittent demand ventilator
IPC: A61M16/00
Filed: 1975-11-19
Abstract: 1521329 Respiratory appliances SEARLE CARDIO-PULMONARY SYSTEMS INC 19 Nov 1975 [20 Nov 1974] 47612/75 Heading A5T In an intermittant demand ventilator there is provided a flow of breathing gas to the patient, who may breath at his own rate, together with a timing arrangement whereby a deep breath is provided to the patient at predetermined intervals in synchronism with the patient's own breathing, and there is also provided an arrangement whereby if the patient ceases to breath normally a regular mandatory breathing impulse of gas is provided to assist respiration together with the above mentioned deep breaths, there being an alarm system to audibly indicate the cessation of patient's breathing. Gas is supplied to the patient from a ventilator 6 via an airway 154 and a fitting 7, the exhalation valve 157 being normally open. A tube 9 is used to sense a lowering of pressure in airway 154 due to inspiration and cause the ventilator 6 to provide a volume of air. At the same time the ventilator sends a signal via conductors 292 and 21, through a signal processor 23 to a junction 24 from whence it passes to a first actuator delay logic board 32 an inihibt logic board 29 and an alarm counter 27. A timer 34 sends signals at selected intervals to the logic board 32 and if such a signal is being held in the logic board when another signal arrives from the ventilator, board 32 sends out a signal to junction 38 from where one signal goes via conductors 39 and 361 to the ventilator 6 to initiate a deep breath cycle, while the other signal goes via a second actuator delay logic board 42 to inhibit logic board 29 and negative inhibit logic board 44, which boards are effective respectively to open valve 13 and close valve 16 allowing an increase in pressure in pipe 12 which causes exhalation valve 157 and valve 63 to be closed, thus forcing the patient to take up mandatory deep breath. At the end of the doop breath cycle the ventilator reverts to its normal mode until timer 34 starts a deep breath cycle again. If the patient fails to breath normally then the ventilator operates to provide time triggered mandatory breathing.

In an electronic digital computer having a fast store divided into numbered pages and one or more backing stores, a single level address facility is provided whereby, for an address supplied as block and line digits, corresponding page and line digits are produced for the address selection mechanism of the fast store. As described, the blocks into which the backing stores are divided are of equal storage capacity to the pages and are transferable between the backing store or stores and the fast store. Lines are sub-divisions of blocks. The computer comprises a set of selection registers each of which may carry an address in the form of page (p), block (b), line (l) and optional incrementer (i) digits. In operation, whenever b, I and i digits relating to a desired address are supplied to a register of the set, the b digits are also supplied to a block directory comprising as many storage locations as there are blocks. If the required block is not already in the fast store then a block transfer operation is initiated whereupon the block directory issues signals representing the corresponding p-digits of the address to the selection register. Means are provded for selecting a register of the set and providing the p- and l-digits to the address selection mechanism of the fast store. Everytime a selection register is selected, the incrementer digits are added to the l-digits, overflow into the C-digit field leading to a comparison of the modified C-digits with an upper limit address B. In a multi-programme arrangement, each programme may be written as though it has access to blocks in the range O to B if the digits b are modified for use in the block directory by the addition of a float Bo. The fast store may comprise a magnetic core store and the backing stores magnetic drums.

Title: Binary Decoding Positioning Device
Inventor: SAYLOR WILLIAM HENRY
Filed: 1968-10-15
Abstract: 1,182,406. Digital-to-analogue converters. W. H. SAYLOR. 15 Oct.. 1968, No. 48744/68. Heading G4H. A positioning device responsive to coded signals comprises in the form of Fig. 1 a number of arcuate armatures 10-14 pivoted about a common print and spring loaded so as normally to have gaps 20-23 which are straddled by solenoids 24-27. The gaps have weighted values and the effect of energizing a solenoid is to close the corresponding gap so that the last armature 10 moves through an angle equal to the sum of the gaps closed. The gaps may have values 1, 2, 4, 8, the input being in binary code. The code may alternatively be in Gray code, excess-3 code or in 1, 2, 4, 2 code. In another form, Fig. 2, there are three arcuate armatures 58, 59, 60 having intermediate gaps 75, 76 valued 2 and 1. These are selectively closed by solenoids 65 and 66. The other two bits are applied to solenoids 67, 68 which control the position of an end stop 77 against which the end armature 60 is caused to bear by spring 85. The position of the stop 77 is raised by energization of solenoid 67 to subtract 4 units and lowered by energization of solenoid 68 to add four units. The four input bits therefore have values 1, 2, 4 and - 4. An arm 78 on the armature 58 has a toothed rack and pinion connection with a print wheel 100. A number of similar assemblies may be placed side by side in a pack to print a number of digits.

Title: Improvements in Guidance Systems for Projectiles or Missiles.
Inventor: MACLUSKY GORDON JOSEPH REDMAN
IPC: F41G7/26
Filed: 1963-12-12
Abstract: 1,164,272. Missile guidance. BRITISH AIRCRAFT CORP. Ltd. 1 Dec., 1964 [12 Dec., 1963], No. 49227/63. Heading H4D. [Also in Division G3] A guidance system for a missile having flight path controls and rotating about its axis during flight, includes a projector external to the missile for aiming a beam of infra-red, visible or ultraviolet radiation at the target and a rotary pattern device for splitting the beam crosssection into sectors and for rotating the sector pattern; a detector responsive to the radiation which is mounted on the missile offset with respect to the missile axis; and means receiving the detector output and responsive to the frequency modulation of the latter resulting from the rotations of the sector pattern and the detector to adjust the flight path controls in response to the frequency modulation and thereby to steer the missile towards the beam axis. In Fig. 1 there is shown a missile 1, a beam of light split by a rotating pattern device into a large number of sectors, and the beam axis 2 about which the beam is rotated and towards which the missile is to be steered. The missile carries two arms 5a and 5b which have at their ends a light detector 3 and a balance weight 4, respectively, and it is also provided with fins 6 and 7 which control the flight path of the missile. In the example shown the directions of rotation of the missile and the sector pattern are the same and consequently the number of sectors of light through which the detector 3 passes is less while the detector is traversing the outer side of the beam than when it is traversing the half rotation which is nearer to the beam axis. This results in the output of the detector 3 being frequency modulated. The missile includes a control unit containing circuits which convert the modulated signal from the detector into a waveform which after amplification controls the movements of the fins 6 and 7. As the missile is spinning about its own axis, due to the fins being given equal and opposite " standing " angles of incidence, the fins must be given an oscillatory movement in order to steer the missile towards the beam axis. This oscillatory movement is at the frequency of rotation of the missile which is also the frequency at which the output of the detector 3 is frequency modulated. When the missile axis coincides with the beam axis, the missile and the sector pattern are rotating in the same direction the whole time and consequently there is no frequency modulation of the output of the detector 3. The system operates if the angular velocity of the missile is greater or less than that of the sector pattern, and/or if the missile rotates in the same or the opposite direction to the sector pattern. The invention can be applied to projectiles of the " bazooka " kind, the arms 5a and 5b and the fins 6 and 7 folding away within the body contour for launching but pivoting outwards as soon as the projectile has left the launching tube.

Abstract: 1374477 Vehicle buff and draw gear CARDWELL WESTINGHOUSE CO 1 Nov 1971 [20 Nov 1970] 50723/71 Heading B7T [Also in Division F2] Buff and draw gear for a railway vehicle coupling comprises rubber pads 52, 54 (Fig. 1), a coil spring 62, and a double-acting hydraulic piston-cylinder shock absorber (Fig. 8). A flow path from one side of the piston 32 of the shock absorber to the other comprises a throttle, formed by a metering rod 86 co-operating with an orifice 82, in series with a spring-biased valve element 262 which opens in response to a certain pressure difference across the piston to open the flow path. Thus, on impacts in buff, a doubleacting check valve 70, communicating with a flexible-walled reservoir 76, closes and there is no flow across the piston until the pressure in front of the piston builds up and displaces the valve element 262 against its spring 266 to uncover passages 84. Should an abnormal pressure build up a pressure relief valve 72 opens. On impacts in draft, when the pressure builds up, the flow is along passages 84, past the opened valve element 262 and through the orifice 82 metered by the rod 86. Draft impacts are cushioned by the rubber pads 52, 54 acting in parallel with the hydraulic shock absorber. When impacts in either direction have lessened, the valve element 262 closes the passages 84 and the shock absorber is urged back to its neutral position by the coil spring 62 or the rubber pads 52, 54, depending on the direction of movement, liquid seeping past the piston 32 to accommodate the changes in volume of the cylinder chambers.
