Title: Improvements in or relating to medical respirators
Inventor: KIPLING BARRY JOHN
IPC: A61M16/12
Filed: 1970-01-02
Abstract: 1,248,303. Respirators. PYE Ltd. 2 Jan, 1970, No. 243/70. Heading A5T. A respirator comprises a switch 30 which controls flow of gas from a pressure source at port 43A via a pressure regulator into a variable first volume VIA during an expiration period, and controls flow from volume VIA for supply to a patient via a variable restriction 57A during at least part of an inspiration period, a gas container 50A being divided by a moveable member 54A into variable volumes VIA, V2A, respiratory gas pressure in the volume V2A being used to move member 54A to expel gas from volume VIA to the patient and the gas in volume V2A being subsequently transferred to volume VIA for supply to the patient. A pneumatic timing device 21 pressurises a pipe 25 and vents a pipe 26 during the exhalation period, set by control 28, and pressurises pipe 26 and vents pipe 25 during the inhalation period, set by control 27, to control switching valve 30 and a valve 40 in a face mask. During exhalation gas vents from the patient's lungs via the face mask and port 42 and gas flows into volume VIA from volume V2A, and from the pressure source via regulator 45A, which may be calibrated in terms of quantity of gas supplied during inhalation. During inhalation gas is supplied via regulator 45A to expand volume V2A by movement of member 54A to expel gas from volume VIA via valve 30 and variable restriction 57A, which may be calibrated in terms of inhalation period and is set to a value less than or equal to the period set by control 27, to the face mask either via valve 40 or directly via pipe 61. A mixture of gases may be supplied to the patient by providing apparatus as above, such as controls 45A, 57B, valve 32 and volumes V1B, V2B, for each gas. The volume V1 for each gas may have a maximum value dependent on the proportion of that gas in the mixture, which value may be varied by for example a screw such as 62 limiting the stroke of the moveable member. The moveable member may be acted on by a spring to assist movement in one direction and may comprise a free piston with equal or unequal area opposed faces, parallel diaphragms rigidly joined together at equal or unequal area rigid central parts having flexible rolling-diaphragm surrounds, or part of a bellows enclosed within a container, the internal volume of the bellows comprising volume V1 and the space between the bellows and container comprising volume V2.

Title: Improvements in central buffing and draw gear for railway and like vehicles
IPC: B61G9/06
Filed: 1929-01-04
Abstract: 327,446. Spencer, A. Jan. 4, 1929. Combined buffer and draught gear. - A central buffing and draw-gear comprises a draw-rod 3, two sets 1, 2, Fig. 1, of buffing and draw-springs mounted tandem-wise on the drawrod, and fixed abutments 8, 12 for the end compression plates of each set of springs, the compression of one set of springs or of one spring of each of the two sets when buffing and the compression of the other set of springs or of the other spring of each of the two sets when drawing being effected by a collar 10 on the draw-rod between the sets of springs. The coupler shank 7 abuts a front compression plate 6 and is connected to the outer end of the drawrod 3 which passes through the springs and is provided at its inner end with a compression plate 13 secured on the rod by a nut 14. The adjoining springs 1, 2 of each set are separated by compression plates 11, 9 and a nut 10 on the drawrod acts on these plates during buffing and drawing respectively. In buffing, both springs 2 are compressed, and under draught, both springs 1 are compressed. A spring 16 is mounted in a casing fixed to the headstock and a sleeve 17 is adapted to contact with the coupler head during buffing. In Fig. 4, the four springs 19 act during buffing and drawing, stops being provided against which the compression plates 20, 22 abut. In drawing the compression plate 24 attached to the sleeve 23 compresses the front spring of each pair until the sleeves 25 surrounding this spring abut, after which both springs of each pair are compressed in parallel. The springs initially compressed may be more sensitive to light loads than the others. In buffing the front springs are compressed against the plates 24 until the sleeves 25 abut, after which both springs are compressed in parallel. Each pair of springs with their casings &c. may be placed in the reverse order on the. draw rod 3 and may be arranged so that the sleeves 25 abut, a spacer being left between the end of the sleeve 23 and each front compression plate 22 so that the front spring of each pair is compressed until the plate 22 contacts with the end of the sleeve 23, after which both springs are compressed in parallel. The rubber springs may be moulded to metal plates or blocks of rubber, which may be perforated with hexagon &c. shaped recesses, may be used. Springs of steel or rubber bars may be used.

Title: Improvements in and relating to d.c.í¬a.c. or frequency conversion circuits
IPC: H03D7/14
Filed: 1946-01-07
Abstract: 637,783. Valve modulator, amplifier, circuits. CURRAH, L. E. Jan. 7, 1946, No. 549. [Classes 40 (v) and 40 (vi)] [Also in Group XXXVIII] In an electric conversion circuit, Fig. 3, valves V1B and V2B together with the centre tapped secondary of transformer T (which is A.C. energized at, for example 10 kc/s., from source S) comprise a bridge circuit, the output diagonal of which consists of a double supply frequency tuned impedance Z1 in series with a supply frequency tuned impedance Z2, the output voltage across which is supplied to an amplifier A and rectifier R. The valve cathodes are connected to the lower end of Z2 and the control grid return of V2B through respectively fixed and variable resistances R3, R4, while a signal derived for example from a bridge-type strain gauge, is applied to the control grid of V1B. The bridge is balanced to give zero output for zero signal by adjustment of R4 and the balancing condensers which are connected between the valve anodes and earth. On application of a D.C. or A.C. signal to the control grid of V1B, the bridge is unbalanced and an A.C. output voltage is developed, of the same frequency as the A.C. source S and proportional in amplitude to the input signal. The output A.C. voltage may be amplified, rectified and applied to operate appropriate equipment, for example, an indicator. By choice of appropriate cathode resistance values, the valve impedances may be caused to vary proportionately to changes of anode voltage, thus maintaining balance. The voltage and/or frequency of the anode supply may be stabilized, as may be the heater current. A " magic eye" indicator may be connected across the output to facilitate balancing. Detailed description is given of the procedure for balancing and for the choice of matched valves.

Title: Digital control systems
IPC: H04L7/033
Filed: 1972-01-06
Abstract: 1327001 Automatic frequency and phase control systems INTERNATIONAL BUSINESS MACHINES CORP 6 Jan 1972 [16 Feb 1971] 553/72 Addition to 1279026 Heading H3A A digital system for synchronizing a clock signal with a received data signal comprises: means for detecting the phase error between the received data signal and a signal produced by a counter to generate a digital phase correction signal; further means for generating a digital frequency correction signal; and means for adjusting the start and stop of the counter in response to the two correction signals. Counter 12 counts symmetrically from a negative value to a positive value, and passes through zero at the instant when a data pulse should arrive on line DATA REC'D. The count at the actual instant of arrival of a data pulse is an indication of the phase error, and is recorded in register 42. Gates 56 are then suitably enabled to add the previous phase and the new phase error in ADDER 54 and the sum is divided by 2 at 64 to produce an average phase error which is stored in register 62. Gates 56 are then enabled to add the new phase error to the count in frequency register 60, and finally the new phase error is written into register 58 ready for deriving the average phase error during the next cycle of operation. The phase and frequency correction signals thus obtained are weighted by suitable scaling factors in circuits 66, 68 and are fed back on lines 70, 74 to control the start and stop times of counter 12.
Patent GB-1458503-A (GB)
IPC: F02D3/00
Filed: 1973-01-04
Abstract: 1458503 Controlling fuel injection systems PETROL INJECTION Ltd and HE JACKSON 31 Dec 1973 [4 Jan 1973] 569/73 Heading F1B A fuel injection system for an I.C. engine comprises supply and return conduits 3 and 7, at least one injector 5 connected to receive fuel from the supply conduit and a fuel pressurizing device (pump 2) to supply fuel to the supply conduit, the return conduit 7 including a valve closure member 402 resiliently biased towards a closed position and movable against the bias by pressure in the return conduit and means (diaphragm 407 and chamber 408) connectible to the engine intake manifold and operable to increase the resilient bias in response to a drop in manifold vacuum below a predetermined value. Chambers 408, 409 are connected via conduits 410, 411 to the engine inlet manifold and a point immediately down-  stream of the air cleaner, respectively. Under partload, the intake manifold vacuum raises diaphragm 407 and holds rod 412 out of engagement with diaphragm 402. The characteristics of a spring 406 are such that the biasing force it exerts is substantially constant over the range of positions of diaphragm 402, so that a substantially constant fuel pressure is maintained upstream of the relief valve 6 while rod 412 remains clear of the diaphragm 402. Thus the amount of fuel issuing from injectors 5 depends only on the period for which they are open. When the throttle valve 12 is nearing its fully open position, the low inlet manifold vacuum is insufficient to keep rod 412 clear of diaphragm 402, so that the biasing force on the latter is increased, thereby increasing fuel pressure upstream of the valve 6 ensuring increased fuel injection from the injectors 5. The length of time for which injectors 5 discharge fuel is determined by the engine air intake flow-rate by electrical pulses produced by a switching unit 8 controlled by a timing switch 14 as described in Specification 1363631. The control pulse length may be varied in response to engine conditions e.g. intake manifold temperature and cooling water temperature by valves 400, 401 as described in that Specification.
