Abstract: 986,120. Drilling by cathode beams; making magnetic plates. RADIO CORPORATION OF AMERICA. July 25, 1961 [Aug. 18, 1960], No. 26966/61. Headings B3A and B3V. [Also in Divisions H1 and H3] Clusters of small holes defining discrete storage regions are drilled in a magnetic plate by a pulsed electron beam. The plate may be formed of ferrite, molybdenum permalloy or 50% nickel and 50% iron, and as shown in Fig. 2 is provided with grooves 32 linking the holes 12. The grooves may be produced in the plate by a moulding operation prior to drilling the holes, or may be formed by the electron beam. The plate is demagnetized before the drilling operation is commenced to prevent the formation of a space charge, and is moved mechanically or is electrically scanned by the focused electron beam so that successive electron pulses are applied to different hole positions. This scanning process is stated to reduce localized heating which may adversely offset the magnetic properties of the plate and is repeated until the drilling operation is completed. The plate surfaces and holes are then coated with an evaporated layer of copper or other conductive material which is built up in thickness by an electrodeposition process. Subsequently both faces of the plate are ground clean of conductive material so that the conductive deposits in the holes and grooves constitutes the circuit wiring. When the plate is formed of conductive magnetic material, the surfaces and holes are first coated with an insulator such as an evaporated layer of plastic, silicon monoxide or silicon dioxide. In a modification, Fig. 3 (not shown), the grooves are omitted and the conductive material applied to the surface of the plate is selectively removed by an electron beam. The conductive coating left on the plate surface then forms the necessary wiring. Details of the electron beam apparatus is also described (see Division H1).

Title: Improvements in or relating to breathing apparatus
Inventor: FITT PETER WILLIAM
IPC: A62B9/02
Filed: 1960-06-11
Abstract: In a high altitude breathing equipment the diaphragm of the demand regulator has, associated with it, a spring which tends to create an excess pressure in the breathing circuit.  This spring is, however, normally held clear of the diaphragm by means actuated by the supply pressure.  The gas supply is fed to the actuating means through a restricted choke and a duct to which an aneroid controlled outlet valve is connected.  Below a predetermined altitude this valve is closed and the spring is held out of engagement with the diaphragm but above that altitude the outlet valve opens and the gas pressure holding the spring is released, so that the spring then bears on the diaphragm.  The equipment described is identical with that described in Specification 944,931.  Specifications 785,371 and 944,933 also are referred to.

Abstract: 535,521. Adsorption of gases. PITTSBURGH RESEARCH CORPORATION. Oct. 6, 1939, No. 27356. Convention date, July 31, 1939. [Class 1 (i)] In adsorption and like processes wherein a gas is treated with adsorbent &c. in a series of compartments, the gas flow is divided in predetermined proportion between two adjacent compartments, and is progressively advanced through the series by maintaining the flow through the second of the two compartments that have been in use while diverting the flow from the preceding compartment to the next succeeding one. A re-activating gas is passed through one or more of the compartments not in use for adsorption, and cooling and heating fluids may be passed through coils in the adsorption chambers. The apparatus preferably comprises four adjacent rectangular chambers, of which two are shown in section in Fig. 2. Each chamber contains two adsorbent beds 7, 8 operating in parallel. The gases are admitted by a disc valve 16 rotating intermittently on a fixed disc having a port leading to each chamber. The valve successively takes up eight positions, the first two of which are shown in Figs. 12 and 15 respectively. The port for admission of gas to be treated covers the inlet of one chamber and part of that of another; the port for regeneration gas is smaller; it communicates with the regeneration gas inlet 36 through a rotating trunk 39 (Fig. 2). Co-operating with the disc valve 16 are similar valves controlling the steam and water which are passed through the coils 12, 13 for heating and cooling purposes.

Title: Pulse flow sensing means particularly for milking parlours
IPC: A01J5/017
Filed: 1973-06-09
Abstract: 1469761 Milking machines M R LOLE 3 June 1974 [9 June 1973] 27651/73 Heading AIM [Also in Divisions G1 and G3] A pulse flow sensor comprises a member displaced by each flow pulse of liquid in a conduit, a capacitor receiving from the sensor a respective control signal for each pulse, and a resistor providing a leakage path for the capacitor. The sensor 31 may sense the milk flow in milking equipment and comprises, Fig. 2, a vessel 50 having an inlet 51 for pulsed milk flow and an outlet 53. The milk pulses are directed by baffle 52 against a vane 54 pivoted at 55 and connected to an exterior arm 56 moved by the vane between air supply and receiver nozzles 58, 59 of the sensor. As long as pulsed milk flow continues, the sensor thus transmits air pulses via diaphragm amplifier 21 and non-return valve 39 to a reservoir or capacitor 38 which provides a continuous signal via restriction 40 to a fluidic OR-NOR module 20. The latter normally supplies a continuous signal through line 23 to the secondary input of signal-shaper module 19. When milk flow ceases and the time delay provided by capacitor 38 and restriction 40 has elapsed, the signal transmitted via lines 25 and diaphragm amplifier 22 to pilot operated valve 13 is removed causing the latter to switch its output. As a result servometer 12 closes the vacuum supply clamp, servometer 11 opens an air clamp, and servometer 34 tensions a cord (88, Figs. 6, 7 not shown) to move the milking cluster away from the cow. In addition, the signal to pilot operated valve 28 bleeds away slowly through valve 16 allowing valve 28 to change over. Capacitor 29 thus supplies air for up to one minute, depending on the setting of restrictor 30, causing temporary switching of pilot operated valve 27. Servometer 10 thus opens the milk supply clamp to allow complete discharge of a milk receiving jar into a bulk storage vessel before the clamp again closes. The milk supply clamp can also be opened manually by valve 17. Flow sensor 31 can be switched off by manual valve 18 so that cluster removal is not automatic. The milking cycle can be started or stopped by buttons 14, 15 respectively. The latter and valve operating levers are mounted on a common control box (61, Figs. 3, 4 not shown) at each milking point. A modified flow sensor comprises a curved flexible tube through which the milk passes, the pulses tending to straighten the tube so as to deflect a pivoted lever which as before, interrupt air nozzles. In a modification the system is operated electrically, the pneumatic parts of flow sensor 31 being replaced by a magnet and reed switch or by a coil sensor. The resulting electrical pulses are stored in a capacitor and leaked away via a resistor when milk flow ceases, the clamps being solenoid operated.

Filed: 1939-10-11
Abstract: 535,308. Electric switches. PRENTICE, H. B. Oct. 11, 1939, No. 27653. [Class 38 (v)] Contact carrier means, such as a rotatable or displaceable bar, has a quick-release mounting comprising resilient means which permits the bar, &c. to be mounted and unmounted without the necessity of dismantling the mounting or associated parts, and which permits the bar &c. to have a longitudinal floating action under the resilient control. The resilient provision may be in a bearing at one or each end of the bar, or it may be located between the ends. As shown, rotatable contact carrier bar 2, Fig. 1, has at one end a resilient bearing comprising a pin 3 slidable in an axial hole in the bar 2 and urged away from the bar by a spring 4, Fig. 2, located between a fixed washer 5 on the pin and a movable washer 6, dished or plain, which may be captive on a reduced part 11 of the pin. The other end bearing may be similar, or be of any ordinary kind, e.g. a dog 13 rotatably associated with a spring controlled toggle device 14 through a lost-motion connection. Various similar constructions of bearing are described. The bar may be readily assembled in the casing 8 if the pin 3 is first pushed inwards, the end 10 dropping eventually into its pivot hole in the casing, or into a slot if the bar is of the displaceable kind. A construction with several axially aligned bars is referred to.
