Title: Improvements in or relating to thermally-actuated fluid-control valves
Inventor: BRANSON CHARLES D
IPC: G05D23/13
Filed: 1955-06-30
Abstract: 782,309. Thermally - actuated valves. ROBERTSHAW-FULTON CONTROLS CO. June 30, 1955 [Oct. 26, 1954], No. 18994/55. Class 135. In a temperature regulator comprising a housing 10 adapted to be disposed in the fluid stream of a cooling system of an engine for example, a thermally-responsive device 34 insensitive to pressure changes and mounted to be responsive to temperature changes upstream of the housing 10, two sleeve -valve closures 40, 70 are connected to the device for alternately controlling the flow through the housing 10 and one or other of the closures 40, 70, respectively, according to the fluid temperature. When the engine coolant is below a given temperature the lower part 52 of the main closure 40 is seated on a plate 22 so that coolant flowing in the direction of the arrows passes through the by-pass closure 70 via apertures 78 and enters a by-pass connection 104 by way of openings 18 in the housing 10. Upon the desired temperature being attained the fusible material in a casing 34 undergoes a large volumetric change on passing from a solid to a liquid state and elevates the main closure 40, against the bias of a spring 80, as well as the by-pass closure 70 attached thereto thus preventing coolant flowing to .the connection 104 and directing it across the space between the part 52 and plate 22 and through the interior of the closure 40 into a radiator by way of apertures in a web structure 44 at the top of the closure 40. When the coolant temperature falls below the given value the fusible material solidifies and contracts whereupon the spring 80 returns the parts to the position shown. The plate 22 embodies a check valve 84, shown in the closed position, to vent air that may otherwise be trapped below the housing 10 and to prevent coolant leakage through the main closure 40 when it is closed. A bushing 64 is provided to prevent leakage between the main closure 40 and the housing 10, the bushing only becoming effective whenever a pressure differential exists across the closure 40. The valve is secured in the engine cylinder head 92 with the interposition of gaskets 98 and 102.

Title: Process for the recovery of di-ú=úsúp-butyl ether
IPC: C07C41/42
Filed: 1958-06-13
Abstract: Di-sec-butyl ether is recovered from mixtures with dimers or codimers of butylene and/or propylene in the presence or absence of di-iso-propyl ether by adding methanol in an amount slightly in excess of that required to form azeotropes with the polymers and the di-iso-propyl ether if present and distilling; the methanol forms azeotropes with all components, the azeotropes with the isopropyl ether distilling first and the hydrocarbons following. The mixture may be one obtained as a by-product in the formation of alcohols by acid hydrolysis of propylene and/or butylenes.  The volume ratio of methanol to isopropyl ether may be 1:3 to 1:2 and to hydrocarbon 3:1 to 1:5:1.  Methanol is recovered from the overheads by adding water and recovering methanol from the aqueous layer by distillation.

Title: Improved radar system employing frequency modulation
IPC: G01S1/02
Filed: 1945-07-25
Abstract: 621,846. Radiolocation. RUST, N. M., and PARTINGTON, G. E. July 25, 1945, No. 19103. [Class 40 (vii)] A frequency-modulated radar system, wherein reflected waves are mixed with the transmitted waves to produce a beat note, transmits frequency-modulated signals having a constant rate of change of frequency so that the beat rate is proportional to range, and includes a variablefrequency selector circuit so that signals from various ranges may be selected and displayed in succession. In the Figure, the generator 3 produces a sawtooth waveform which modulates the frequency of the transmitter 6. The echosignal is mixed with a portion of the transmitted signal, which is fed through the adjustable coupling 8, to the receiver 12, the demodulated output of which contains beat frequencies depending upon the ranges of the echo-producing objects. The signal is passed to a broad-band amplifier 13 having, for example, a pass-band of 5 to 25 kc/s, the output of which is fed to a mixer 14 together with oscillations from a variable-frequency oscillator 15 having, for example, a, frequency range of from 105 to 125 kc/s. The frequency of the oscillator 15 is controlled by further sawtooth oscillations (a) from the generator 5, which also controls the horizontal sweep on the cathoderay tube 10. The output from mixer 14 is applied to a 100 kc/s fixed frequency filter 9, the output of which is used to produce a deflection on the cathode-ray tube. Thus for each particular value of the wave (a), and thus for every position on the cathode-ray tube scan, there corresponds a certain range, producing a beat frequency which will be selected and applied to the display unit. For certain purposes it may be advantageous to vary the frequency of the waveform from generator 3, while maintaining its rate of change constant. Also, means may be incorporated for varying the band width and/or gain of the device 9 with range. For carrying out a restricted search in range, manual control of the output of generator 5 may be provided. Alternative indicating means, such as a P.P.I., aural indicator, or a meter, may be used. The Provisional Specification describes a system in which the frequency-modulating wave is of symmetrical triangular form. The slope of the modulating wave may have a number of different selectable values, whereby the rate of change of frequency may be selected to correspond to a desired range of distances. In the system employing sawtooth modulation the frequency of the exploring wave is synchronized with the cathode-ray tube time-base so that the " fly-backs " of both occur simultaneously Specifications 542,634, 581,169, 592,596 and 620,56S are referred to.

Title: Epicyclic change-speed gear hubs
IPC: F16H3/44
Filed: 1973-04-19
Abstract: 1433243 Change-speed gear RALEIGH INDUSTRIES Ltd 1 April 1974 [19 April 1973] 19137/73 Heading F2D A two-speed back-pedal-shifted hub gear for a pedal cycle comprises a shift cam 23, which in one relative angular position frees a first set of pawls 17a, pivoted in a pawl carrier 16 in a lost-motion drive connection between a driver 20 and a ring gear 15, whereby the pawls 17a engage a hub shell 19 for direct drive, whilst in another angular position the shift cam 23 engages tails 17a<SP>11</SP> of the pawls to pivot them out or engagement with the hub shell, whereupon a second set of pawls (not shown) drives the hub shell from a planet carrier 14 at reduced speed by reacting on a fixed sun 12, the shift cam 23 being connected for forward rotation with the driver 20 by a third one-way pawl 26, pivoted to the driver 20 and engaging teeth 25 on the shift cam 23, the arrangement being such that, on resuming forward pedalling after each back pedal operation, the shift pawl 26 indexes the shift cam 23 through a single ratio step only. The various lost-motion connections are as follows. An intermediate driving member 22 is rigidly connected to the ring gear 15 by lugs 22a passing freely through the pawl-carrier 16 into close-fitting recesses 15c<SP>1</SP> in the ring gear 15, the intermediate member having a lost motion connection with the driver 20 by a rectangular dog 20a on the latter angularly movable in diametrically opposite recesses 22b<SP>1</SP> in the former. The pawl carrier 16 has a lost motion connection 16a, 15c with the ring gear 15 this connection allowing disengagement of a back-pedal brake, when provided, before the ring gear is driven forwards. In operation, during forward pedalling the driver 20, pawl carrier 16 and shift cam 23 rotate together, thus being permitted by drag springs 28a, 24 on the carrier 16, and shift cam 23 slipping on the fixed spindle 11. When forward pedalling ceases the hub overruns and the driver 20 holds both the pawl carrier 16 and shift cam 23 stationary and no relative shift movement occurs. On back-pedalling the lost-motion connection 20a, 22b between the driver 20 and intermediate member 22 is first taken up, during which the shift pawl 26 overruns the shift cam teeth 25 by a single tooth, further back pedalling being prevented by a back-pedal brake, when provided, and/or by a catch pawl 27 on the driver 20 engaging a flank 22b<SP>1</SP> of one of the two recesses 22b in the intermediate member 22, thereby causing the catch pawl 27 to pivot into engagement with the shift cam teeth 25 and prevent any further relative movement inspite of any further back pedalling. On resuming forward pedalling the driver-mounted shift pawl 26 indexes the shift cam 23 a single tooth step forwards causing the cam 23 to lift the pawls 17a for downshift or to release them for upshift.

Filed: 1962-05-18
Abstract: 971, 559. Tufting machines. RIBBLE CARPETS Ltd. Aug. 19,1963 [May 18, 1962], No. 19170/62. Heading D1G. The needle carrier of a tufting machine is moved endwise, for shifting the needles from one line of stitching to another, by screw-and-nut means operating between the carrier and a fixed part of the machine, and under the control of a pre-formed pattern-defining member. As shown, a needle bar 9 carrying needles 10 is reciprocated vertically by rods 7 fixed to brackets 20 formed with sleeves 21 slidably engaging a shaft 18 which is restrained from endwise movement. Brackets 22, fixed to the needle bar, carry nuts 23 engaged with screwthreaded portions 19 of shaft 18. The latter carries ratchet wheels 16, 17 the teeth of which are opposed to each other. Pivoted pawls 25, 26 are normally held in alignment with the respective wheels 16, 17 by linkages 32, 33, pivoted at 34, 35, against the bias of springs 29, 30. The linkages carry respective sensing members 36, 37 directed towards a pattern chain 39 which is carried by drum shafts 40, and the segments of which carry pins 38. A pin engaging a sensing member serves to shift the associated linkage out of engagement with the'associated pawl, the latter then moving out of alignment with the associated ratchet wheel. On the subsequent upward movement of the needle bar and shaft 18, the other pawl co-operates with its associated ratchet wheel to turn shaft 18 for moving the needle bar endwise in one direction or the other. It is stated that oscillation of shaft 18 may be effected alternatively by rack-and-pinion, cam or crank and connecting rod mechanism, and that the driving means for the operation of these parts may be a rotating cam or a series of electromagnets.
