Title: Improvements in and relating to containers for deodorants and the like
IPC: A61L9/12
Filed: 1937-03-11
Abstract: 492,169. Containers for deodorants &c. BRITISH FUMIGANTS CO., Ltd., and SLATER, W. C. March 11, 1937, No. 7206. [Class 81 (i)] In a container for deodorants and the like, comprising a base securable to a supporting surface and a detachable perforated or openwork closure member, the base has a catch which is concealed b the closure member and which, in the act of applying the latter to the base, is caused to engage the wall of, and retain, the closure member, the catch being thereafter disengageable only by the insertion of a tool through an aperture in the closure member not distinguishable from neighbouring apertures. As shown the base a comprises a plate, securable to a wall by screws a<3>, and having on its lower and two side edges, bent-over flanges a<1>, a<2>, forming a slide-wav for the insertion of a deodorantcontaining cover c comprising a frame with flanged sides and bottom c<1>, c<2> a perforated front and an open back. On sliding in the cover a leaf spring catch b on the base is depressed by the lower edge c<2> and engages behind it to prevent removal. To release the catch a rod is inserted through a hole c<5> in the cover which is indistinguishable from adjacent holes. The lower edge c<2> of the cover, and its flange, are recessed as at c<3> to receive the spring b. Brackets or the like may be provided in the cover, to hold the deodorant away from the lower end. The container may be of diamond, triangular, or semicircular shape the catch being arranged to operate substantially when the cover is fully inserted into the base. The spring b may be replaced by a spring-operated or weight-operated pawl. Specification 407,046 is referred to. The Provisional Specification describes a circular or polygonal container having a cover receivable within a flange or rib on the base and lockable thereto by two or more radial plungers operated by a spring or by hand ; in the case of two plungers they may be connected by a central spring- held link or lever and may be bevel-nosed. This Provisional Specification also refers to containers provided with catches adapted to engage lugs on hinged or flanged cover plates.

Abstract: 765,825. Non-linear and pulse code modulation circuits. STANDARD TELEPHONES & CABLES, Ltd. March 11, 1955 [March 29, 1954], No. 7228/55. Addition to 659,576. Classes 40(5) and 40(6) In a circuit of the type described in the parent Specification in which an input signal is applied to a non-linear circuit and the outputs combined to give the desired curve each circuit comprises a first rectifier 6 and second rectifier 5, arranged in series opposition, Fig. 1, the rectifiers being biased to present a threshhold and saturation voltage level so that the output 38 produced from the input 12 is according to the curve 14, 15, 16, Fig. 2. In the absence of an input, the bias potential E<SP>3</SP> drives current through resistors 7, 8 and rectifier 5 to battery E<SP>1</SP> to set up and threshhold voltage E<SP>2</SP> eaual to potential E<SP>1</SP> plus the potential difference across resistor 8. Until the input exceeds E<SP>2</SP>, a rectifier 6 is biased off, the output voltage then rising with input as the current through resistor 7 falls, curve 15, Fig. 2. When the input equals or exceeds E<SP>3</SP> rectifier 5 is biased off and the output remains constant, curve 16. A number of circuits are employed with differing bias sources E\ E<SP>3</SP>, Fig. 5, and the outputs added to give the curve 17 which can be employed as the compander or expander in a pulse code modulation system, Figs. 3, and 4 (not shown). Each circuit, such as 5a, 6a, 7a, 8a, Fig. 6, is biased from taps on potential divider 25 and the signal is fed out over a de-coupling resistor 35a to a common resistor 37. Adjustment of the bias from tap 29 varies.the amplitude of input volts necessary to exceed the threshold voltage. In a modification, Fig. 9, decoupling capacitors 51 are added and two of the intermediate resistors 62d, 62e are tapped on potential divider 47. Since the output of the extreme non-linear circuits are much larger than the rest, resistors 55, 57 are included to attenuate the output. Distortion of pulses due to capacity effects are overcome by the use of compensating capacitors 63. A similar circuit (Fig. 10, not shown) may be used as the expander. Where a series of characteristics such as the curves A, B and C of Fig. 8 are required in order to code an input signal, calculated fractions from the non-linear circuit are applied in one sense or the other to the primary of transformer 40, Fig. 7. A three-element codeis obtained by feeding through separate mixing circuits B 'and C and delays 43, 44 before the final addition across resistor 45. Specification 535,860 [Group XL] also is referred to.

Title: Method and apparatus for manufacturing fuel gas
IPC: C10L3/00
Filed: 1935-03-14
Abstract: 437,570. Gas plant; combustible gas mixtures. STUART, A. T., 583, Avenue Road, Toronto, Canada. March 14, 1935, No. 7881. Convention date, March 14, 1934. [Class 55 (ii)] A fuel gas mixture of constant characteristics for industrial and domestic purposes is produced from constituent gases of different characteristics and obtained in varying ratios by electrolyzing water, gasifying solid or liquid fuel with the oxygen to provide one constituent, carburetting the hydrogen and weighting it with atmospheric nitrogen to provide the other of similar calorific value and specific gravity and mixing the two. The process is so operated that the electrolytic oxygen is principally used for manufacturing gas for peak loads and the base load is principally obtained from the electrolytic hydrogen. Surplus oxygen obtained, e.g. in summer conditions, may be stored, e.g. under high pressure or liquefied. Electrolyzers 3 supply hydrogen and oxygen respectively to holders 7, 11 or pressure storage means 9, 12. Or liquid oxygen may be stored in vessel 13. A gas for carburetting and weighting the hydrogen is obtained in a generator 14 as by producing oil gas by partial combustion of oil with air admitted through pipe 16 or by reforming natural gas, refinery gas, or coke oven gas by a similar treatment. Or producer gas which may be enriched with propane, butane or oil gas may be employed. The hydrogen from pipe 6 and the added gas from pipe 17 pass to a distribution main 18. The electrolytic oxygen with steam from a pipe 21 enters a producer 19 operated with coal, coke, &c., the gas generated passing through a pipe 22 into the distribution main.
Patent GB-599907-A (GB)
Title: Improvements in or relating to frequency counters
IPC: G01R23/02
Filed: 1944-04-27
Abstract: 599,907. Oscillation frequency control. PHILIPS LAMPS, Ltd. April 27, 1944, No. 7939. Convention date, March 4, 1943. [Class 38 (iv)] [Also in Group XXXVI] The current through an inductance is varied by a like amount for each half period of like sign of the oscillation, the frequency of which is to be measured and the resulting voltage impulses across the inductance are integrated to obtain a voltage proportional to the frequency of the oscillation. As shown in Fig. 1, the plate circuit of a pentode amplifier 10 includes an inductance 12 in series with a resistance 14 and battery 16, from which a tap is taken to the screen grid 20. In parallel with the inductance 12 is a diode 22 in series with a resistance 24, the ends of which are connected to output terminals 28, 30. Input terminals 32, 34 are connected to the grid 40 through a resistance 36 and to the cathode 38 respectively. In order to make the output voltage zero at a predetermined frequency, a constant voltage may be opposed to the output voltage, as by tapping off a portion 44 of the resistance 14 and connecting the tap to an output terminal 30<1>. Alternatively, the compensating voltage may be obtained from a potentiometer 58, Fig. 5, across the battery. In a modification, the inductance 12a, Fig. 5, forms one winding of a transformer separating the output circuit from the plate circuit of the valve 10a. The compensated frequency counter or counter type discriminator may be used for frequency stabilization by applying to the input a difference frequency obtained by mixing the oscillation to be stabilized with a pilot oscillation and feeding back the output of the discriminator to the oscillator which provides the frequency to be stabilized. A low-pass filter may be included in the output circuit of the discriminator or the counter to exclude components of the frequency of the voltage impulses and harmonies thereof. Fig. 5 shows the application to frequency-modulated transmission. The transmitter antenna 60 is connected through a power output section 62, a driver or doubler 64, and a separator 66 to an oscillator 52a, which is connected to one side of a mixer 50a, the other side of which is connected to a pilot oscillator 48a. The output of the mixer is applied to the control grid 40a of the discriminator valve 10a. The output of the discriminator is passed through a bandpass filter 68 and a modulating voltage, for example, from a microphone, is applied to terminals 70. The resultant is applied to a reactance valve 56a which is connected to the oscillator. The reactance valve acts both as a stabilizer and as modulator, and while the discriminator maintains the central frequency constant, the output of the oscillator is also frequency modulated by super-imposition of a factor derived from the terminals 70. Specification 20469/43 as open to inspection under Sect. 91 is referred to.

Title: Improvements in and relating to door locks
IPC: E05C3/24
Filed: 1946-03-14
Abstract: 609,441. Swinging latches. BRIGGS MOTOR BODIES, Ltd., and WARD, D. L. March 14, 1946, No. 7974. [Class 44] A lock, for example for use on motor-car doors, comprises a latch 9 pivotally mounted in a horizontal plane and having two lugs 12, 13 projecting from the end face of the door. Lug 13 co-operates with lug 23 on a striker plate secured on a fixed pillar of the door opening to cause rotation of the latch on closing of the door, thereby bringing lug 12 into locking position in relation to lug 23 and permitting a spring-pressed plunger 16 slotted to straddle pivot pin 10 of the latch, to move between face 18 of a shoulder on the latch and casing 17 to maintain the latch in its locked position. To release latch 9, plunger 16 is provided with a stud 28 linked by angle plate 27 and stud 26 sliding in bush 25, to knob 26a on the inside of the door. Knob 26a is accommodated in handle 30 for ease of manipulation by pressure on knob 26a to retract the plunger 16. On opening the door, co-operation between lug 23 and lug 12 imparts clockwise movement to the latch and on releasing knob 26a the end face 19 of the plunger 16 contacts the side face 19a of the shoulder of lug 12, as shown to retain the latch in its unlocked position. To open the door from the outside, lever 33 (Fig. 5) is provided pivoted at 34 and bearing against stud 28, the upper end being connected by link 36 to handle 35. A safety catch 42 pivoted to a bracket on casing 17 is adapted to engage a stud 43 on lever 33 and is provided with a cam face 46 arranged to engage with lug 41 formed on angle plate 27 when this latter is moved' from its neutral position and prevents lever 33 from being moved to retract plunger 16. Another cam surface 47 engages lug 41 when angle plate 27 is moved to neutral position and rotates the safety catch out of contact with stud 43 leaving lever 33 free for operation by handle 35. Spring-loaded balls 48 carried in the sliding stud 26 engage holes in bush 25 and determine the neutral and safety positions of knob 26a. In an alternative safety catch arrangement, lever 33 is pivoted above stud 28 and is operated by a push-button, the safetycatch and stud 43 being located at the lower end of the lever.

Filed: 1925-03-25
Abstract: 249,677. Steele, L. C. March 25, 1925. Folding parper. - The doubling-blade 6 of a machine for doubling sheets of metal or other bendable material is pivoted in a slide 10 reciprocated by crank mechanism 13, 12 through a onerevolution clutch, and is formed with a toe 20 passing through slots 30, 31. The slot 30 is in a slide 27 formed as a rack in gear with pinions 44 on shafts carrying sector-shaped members 7, the slide being influenced at each end by springs 35, 36. A pack of sheets is laid on the table 3 with one edge against the aligned radii of the members 7, and is tilted into an approximately vertical plane by pivoted fingers 55 actuated through linkage by a hand-lever 67. The sheets of the pack are aligned laterally by fingers 56 linked together and actuated by a hand-lever 76. On forward movement of the slide 10 the doubling-blade is carried into the vertical position by the edge of the slot 31, and folds the pack, the members 7 yielding to allow the sheets to pass, thus moving the rack-slide, the spring 36 being displaced by the front end of the slide 10 to permit free movement of the rack-slide. On the return of the slide 10 the doubling-blade falls below the table when the slots 30, 31 register and thereafter the toe of the doubler engages the end 21 of the slot 30 causing the rack-slide to return against the pressure of the spring 35 and positively rotate the members 7 to compress the fold and return the doubled pack to the starting position.
