Title: Decompression regulator for air locks
IPC: G05D16/18
Filed: 1951-01-16
Abstract: 690,144. Air locks. MARPLES, RIDGWAY & PARTNERS, Ltd., and JACKSON. F. S. Jan. 16, 1952 [Jan. 16, 1951], No. 1215/51. Class 68(ii) An apparatus for controlling decompression in an air lock comprises a chamber 6 communicating (a) with the air lock through port 8 and pipe 10, (b) with a pressure source through valve 2, port 14 and pipe 12, and (c) with atmosphere through valve 4, port 24 and pipe 26. The valve stems engage a lever 32 mounted on a pivot in a housing 34 to which a variable pressure is applied, this pressure decreasing as the decompression proceeds. The housing 34 carrying the pivot is acted on by a lever 38 the position of the pivot 42 of which can be varied longitudinally by a screw and nut mechanism. Pressure is applied upwardly beneath the lever by a member 44 moved upwardly into pressure engagement therewith by a linkage and screw and nut mechanism. The member 44 is also moved horizontally by screw and nut mechanism, operated by power or hand, starting from a position beneath the housing 34 and ending at the pivot 42. The valve system is thus operated by the difference between the pressure in the lock and an opposing force which decreases as decompression proceeds.

Abstract: 753,130. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY OF LONDON. Jan. 4, 1945 [Jan. 21, 1944], No. 1220/44. Class 39 (4). A nuclear reactor comprises an outer shell 1 of a size greater than the critical size at which the chain reaction becomes divergent for the particular arrangement and composition chosen, a number of rods 2 of or containing fissile material parallel to one another, each rod being surrounded by a tube 3 made of aluminium or other material of low neutron absorption power. The annular spaces between the tubes and rods are connected to a header 4 to which a slowing- down liquid 5 is led. The slowing-down liquid, which may also act as a coolant, flows through the tubes and issues from the open ends thereof to fill the reactor shell to a convenient level. This level may be controlled by an outlet 6 so as to control the working volume of liquid. In a modification the liquid, after passing through the tubes, is drawn off at the top instead of entering the shell of the reactor and the liquid in the shell is controlled by an inlet and outlet at different levels in the shell. If desired the rods may be made hollow and the liquid may flow through them instead of through separate tubes.

Abstract: 901,416. Sewing-machines. DURKOPPWERKE A.G. Jan. 12, 1961 [Feb. 19, 1960], No. 1293/61. Class 112. A cyclically-operated sewing machine comprising a resilient work-feeding clamp and a needle bar swinging transversely to the direction of work feed is provided with a bar pivotally mounted for movement towards and away from the needle, whereby a workpiece placed around the bar may be inserted in the clamp and upon operation of the machine the bar will serve as a guide for the workpiece. A feed bar 9, supported on the lower arm 2 of a sewing machine, carries at one end a pin 11 pivoted in a block 12 slidable in a groove 13 formed in one arm of a lever, the other arm of which carries a pin 16 which co-operates with a cam groove 17 in a rotary cam disc 6 to effect longitudinal movement of bar 9. To the other end of arm 9 is fixed a plate 10 carrying a block 20 embraced by a spring plate 22 which co-operates with plate 10 to form a resilient work clamp. A bar or plate 28, carried at one end of a two-armed lever 25 is adapted to enter the clamp. The other end co-operates with an adjustable stop screw 36 to regulate the extent of entry of plate 28. As shown, a workpiece 40, to which two strips 41, 42 are attached by a seam 43, is folded over plate 28 and the latter is moved within the work clamp. On operation of the machine the work is fed by the clamp and is guided on the plate 28, while the laterally-swinging needle 8 forms a line of blind stitching which does not appear on the inner surface of strip 42. An aperture 18 in plate 10 uncovers a numeral 1 on the throat plate 19 when plate 10 is at its extreme left-hand position, and uncovers a numeral 2 when plate 10 is at the extreme righthand position. Plate 28 is formed centrally with a needle-passing notch 30 and a line 31. The left-hand end of plate 28 is provided with two spaced lines 32, 32<1> and a numeral 1. The right-hand of plate 28 is provided with two spaced lines 33, 33<1> and a numeral 2. At the start of an operation if numeral 1 appears in aperture 18, one edge of the work is disposed to the left of line 31 and the other edge is disposed between the lines 32, 32<1>. If numeral 2 appears in aperture 18, one edge of the work is disposed to the right of line 31 and the other edge between the lines 33, 33<1>. In a modification, bar 9 makes two strokes per cycle, no stitching occurring during the return stroke, and the work-positioning numerals and lines are not provided.

Title: Improvements relating to the analysis of gases
Inventor: HERSCH PAUL
IPC: G01N27/407
Filed: 1952-01-16
Abstract: <PICT:0707323/III/1> An apparatus for the detection and determination of oxygen in a gaseous mixture comprises a galvanic cell 1 into which the gas is passed through inlet 4, oxygen being absorbed at the cathode 2 to produce an electric current which is a function of the oxygen content of the gas, characterized in that the cathode is completely inert towards the electrolyte and is partially exposed to the gas, whilst the anode 10 is of base metal readily attacked by the electrolyte only in the presence of oxygen.  The cathode is preferably of precious metal, e.g. silver, gold, platinum or nickel plated with silver, gold or iridium, being preferably in the form of coiled or bent sheet metal, Fig. 2, whilst the anode may be copper, lead, arsenic, antimony, antimony amalgam or cadmium.  In preferred embodiments of the invention: (1) the cathode consists of metallic silver, the anode of porous nickel impregnated with cadmium in an electrolyte of caustic potash solution; (2) a cathode of metallic gold and an anode of copper in sulphuric acid as electrolyte.  Oxygen concentrations in the range of 1 p.p.m. to 0.003 per cent. can be determined accurately by a microammeter which can be calibrated to read oxygen concentration directly connected across leads 13 and 14; or the current from the cell can be used for operating control or recording devices.  The cell is calibrated for use by passing through it a gas substantially free from oxygen and adding oxygen generated at supplementary anode 19 at a known rate.  The anode 10 is consumed in use and may be regenerated electrolytically by generating oxygen at an auxiliary nickel anode 15.  The cell can be used for the indirect determination of combustible gases by burning them with a known amount of oxygen and determining the excess oxygen.

Title: Improvements in and relating to navigational computers
IPC: G06G1/00
Filed: 1960-01-13
Abstract: 916,168. Mechanical calculating apparatus. CAMBIASO, O. Jan. 13, 1960 [Feb. 11, 1959], No. 1303/60. Class 106 (1).  A device, particularly for calculating the speed and course of a vessel observed on the radar screen of another vessel, comprises a body 1 having a lower disc 4 and an upper one 7 concentrically mounted, a transparent plate 9 being slidably mounted above the upper disc 7 so that a longitudinal central line 21 on the plate 9 passes through the common axis of the discs 4, 7. In use, the plate 9 is slid upwardly until its indexes 20 are at the zeros of distance scales 18, 19. The lower disc 4 is orientated so that line 21 indicates the course of the observer's vessel as seen on the compass markings of disc 4. The range and bearing of the other vessel is now obtained from a radar screen and plotted on plate 9 using index 13 of the upper disc in co-operation with an angular scale on body 1, together with semicircles 14 on disc 7 which are equidistantly spaced and represent distance to two different scales corresponding with scales 18, 19. Later, the plate 9 is moved a distance corresponding to the distance travelled by the observer's vessel, using index 20 co-operating with either scale 18 or 19 according to the distances involved. The range and bearing of the other vessel is again plotted and disc 7 rotated so that one of the grid lines 17 passes through, or is parallel to, the plotted points, the pointer 15 or 16 then indicating on lower disc 4 the true course of the observed vessel. The portion of grid line lying between the two plots represents, to the appropriate scale in use, the distance travelled by the other vessel and by entering it, together with the time between observations, on a table 23 marked on plate 9, the speed of the observed vessel may be obtained. Lines 22, parallel to line 21, are for use when determining the course to follow in order to pass a safe distance from a vessel which is on a collision course.

Title: Electrical identification system
IPC: B61L25/04
Filed: 1960-01-15
Abstract: 892,273. Electric-selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. Jan. 15, 1960 [Jan. 19, 1959], No. 1493/60. Class 40 (1). In an electrical identification circuit for determining the state of mn open/closed switches kll, a freerunning multivibrator MV steps a ring counter CT to energize one of m oscillators OSC1 ... m to supply a frequency peculiar to that oscillator via output line OL to the inputs of mn field stations U11-Umn. Each field station, e.g. U11 comprises a tuned receiver REC11 &c., a switch k11 and an oscillator OSC11 &c. and is so arranged that receivers REC11-REC1n are tuned to oscillator OSC1, REC21-REC2n to OSC2, &c. Each station of the group U11-U1n has an output oscillator OSC11-OSC1n producing a unique frequency within this group. The outputs of each field station passes via a common line 1L to n tuned receivers REC1 to RECn at the central station. With the counter CT in the first position, frequency-significant A.C. from OSC1 passes to all the field stations, but only receivers REC11-REC1n of the first n field stations are tuned to this frequency, these respond and, where switches K11 &c, are closed, corresponding oscillators OSC11-OSC1n. Thus within this period up to n different frequencies will be simultaneously applied to line 1L, detected by tuned receivers REC1-RECn and corresponding signals, gated with outputs from the ring counter, registered in a device REG so as to indicate the state of switches K11-K1n. This process is repeated for each step of the counter CT. In a modification the lines OL, 1L are replaced by one single line, in which case the m frequencies from oscillators OSC1-OSCm must necessarily be different from the n frequencies from oscillators OSC11 &c. The circuit may be applied to railway control systems, the field stations U11 &c. preferably comprising reed relays and the switches K11 &c. being opened by the presence of a train in an associated section of track. The oscillators and receivers are preferably known types employing transistors. The frequencies utilized may range upwardly from 540 cycles per second in steps of 120 cycles per second.
