Title: Improvements in or relating to apparatus for use in blending or mixing operations
Inventor: HODGSON LEONARD
IPC: A21C1/14
Filed: 1952-01-08
Abstract: 739,374. Thermometers. PRICE & SONS, Ltd., W. April 7, 1953 [Jan. 8, 1952], No. 26136/51. Class 97 (3). Apparatus for use in blending two constituents in substantially constant proportions to obtain a mixture at a required temperature comprises a thermometer having relatively movable indicating and scale means arranged so as to register at a position dependent upon the temperature of one constituent, the scale reading at the position of register giving the temperature at which the other constituent should be in order to give the required mixture temperature. As shown, the apparatus comprises a container 10 for one constituent, e.g. flour, over which detachably fits a sleeve 15 on a thermometer casing 17. This casing accommodates a scale 18 which is rotatable relatively to a pointer 19 and has projections 20, 21 housing thermometer bulbs, each connected to Bourdon tubes which are respectively attached by rack and pinion mechanisms to the scale 18 and the pointer 19. Scale 18 is so graduated that the new scale reading, which results from a variation in the temperature of the flour (in which the projection 20 is dipped), indicates the actual temperature which the water must have in order to produce dough at a certain temperature. In another form, the thermometer unit is also connected to a mixing valve in such a way that water is fed to a container at the right temperature, this container having an outlet valve controlling the flow of the water to the flour.

Title: Improvements in and relating to the purification of benzole
Inventor: SAWYER EDWARD WILLIAM
IPC: C07C7/163
Filed: 1953-09-23
Abstract: Benzole substantially free from non-aromatic hydrocarbons is produced by introducing a benzole containing non-aromatic hydrocarbons into a moving bed of inert material and there subjecting it to a temperature within the range 650-900 DEG  C., preferably7 50-850 DEG  C. and at atmospheric or moderately elevated pressure in the presence of hydrogen or a gas containing free hydrogen.  Compounds containing sulphur may be removed before or after the process.  In a preferred embodiment, a hydro-refined coke-oven benzole or a motor benzole was injected into a fluidized bed of sand or coke at a temperature of 750-780 DEG  C. in the presence of hydrogen, at atmospheric pressure, contact time was about 2 seconds.  The solid particles were separated, reheated and recycled.  The products were fractionally distilled and the benzene fraction collected up to the end of the benzene flat in the distillation curve.

Title: Improvements relating to the recovery of sulphur from gases
IPC: C01B17/02
Filed: 1928-09-13
Abstract: 297,062. Still, C. Sept. 13, 1927, [Convention date]. Right to Patent relinquished. Materials for purifying.-In the process of washing gases with a suspension of metal oxide in a dilute alkali solution to remove hydrogen sulphide, and of regenerating the spent liquor by aeration with recovery of sulphur, a solution of a soluble agent producing foam e.g. a soap, saponin or the like, or an extract of peat, is added to the washing liquid. By this means a greater degree of separation of the sulphur from metal oxide particles is obtained. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of a foaming agent present in the metal oxide in its natural state, as in the case of a suspension of iron oxide prepared from bog iron ore which contains peat. This subject-matter does not appear in the Specification as accepted.

Patent GB-1362451-A (GB)
Title: Radar systems
IPC: G01S13/50
Filed: 1972-06-07
Abstract: 1362451 Radar; a.g.c.; automatic frequency control SINGER CO 7 June 1972 [26 Aug 1971] 26590/72 Headings H4D H4R and H3A In a multi beam Doppler radar system in which the beams are sequentially switched, an alarm is provided when the receiver system locks on to an incompletely suppressed beam reflection instead of the selected beam reflection. Antenna 11, Fig. 5, emits beams 1 to 4 sequentially and from the Doppler returns the aircraft velocity is computed. However, in certain conditions an incompletely suppressed beam may be tracked. In Fig. 7, not shown, the aircraft is performing a roll and although beam 2 is selected incompletely suppressed beam 1 may be locked on to. In the system of Fig. 1, a detector 23 is provided giving an alarm if such a condition exists. Loop 26 tracks the centre or maximum power frequency in the Doppler spectra and feeds a velocity computer 25. Detector 23 is fed with an AGC signal indicative of the maximum power being received for any one beam period. The detector stores the maximum power value received in all beam periods of a given cycle. Whenever an incompletely suppressed beam is locked on to the power received will be much lower than for a normal beam. This results in an unusually small AGC signal being fed to detector 23. The detector determines the difference between this power and the maximum power received in the cycle. For normal selected beam powers and incompletely suppressed beam powers there is a specific minimum difference and detector 23 determines if this is exceeded. If so, an alarm is given. AGC control, Fig. 3.-A signal from loop 26 is fed to detector 22 and integrator 24. Capacitors 67 to 70 are switched by timing unit 16 and each correspond to a particular beam. For large signals FET 82 presents a low resistance to ground and a high resistance for low signals. The signals fed to loop 26 are therefore selectively attenuated to maintain a constant amplitude. Frequency tracking loop, Fig. 2.-The Doppler signals, in the form of a spectrum due to noise, ground clutter &c., are fed to mixer 32, 33 and mixed with quadrature components of a signal derived from oscillator 61. Low pass filters 34, 35 pass only the difference signals and filters 36, 37 shift the signals back into phase before feeding them to multiplier 40. Multiplier 40 provides a D.C. output proportional to the difference between the divided frequency output of oscillator 61 and the peak power or centre frequency of the Doppler spectrum. Integrator 41 smooths the signal from multiplier 40. Capacitors 51 to 54 are switched in sequence by timing unit 16 and each correspond to a particular beam. The integrator output is then used to shift the frequency of oscillator 61 to the peak power or centre frequency.

Filed: 1939-09-27
Abstract: 532,931. Machinery guards. PIRIE, W. J. Sept. 27, 1939, No. 26733. [Class 80 (iv)] In an off-set printing machine a flap 1 is pivotally mounted in the region between the printing cylinder 2 and an adjoining roller 3 and is connected by an arm 4 to a spring-urged stop switch button 5 which is normally in position to ensure flow of current to an electric motor driving the machine. If,. during cleaning or other operation, the operative's hands enter the danger zone, the flap is tilted upwardly and the current cut off. To prevent any possibility of the hands being inserted below the flap without actuating the safety device, the normally non-continuous surface of the cylinder 2 is rendered continuous by attaching thereto, where the surface is interrupted, a sheet metal segment 6 of slightly less radius than the cylinder. The flap may be of fibre and is mounted on a pivot rod 1a. The Provisional Specification refers to the application of a brake when the current is cut off.

Abstract: 1,187,637. Lubricating. TELEHOIST Ltd. 15 March, 1968 [12 June, 1967], No. 27072/67. Heading F2A. In an automatic lubrication unit a lubrication pump has a cylinder 16, Fig. 1, and a piston 17, the latter being actuated periodically by means of an electrically-powered thermal linear motor 19 so as to deliver lubricant to metered injectors (not shown). Lubricant passes from a reservoir 10 to the cylinder 16, via a filter 13 and a valve 15. A heating coil of the motor 19 is supplied with electricity thus causing wax therein to expand and move the piston 17. The valve 15 closes, lubricant is forced into a timing cylinder 41, Fig. 3, and forces a piston 42 against a spring 43. Further increase of pressure in the pump cylinder 16 is transmitted through ducts 48, 49, Fig. 1, to a micro-switch operating cylinder 50 having a piston 51 therein which acts against a spring 54. An operating-rod 52 is attached to the piston 51 and operates a micro-switch (not shown) to cut-off the supply of electricity to the motor 19. Surplus lubricant in the pump cylinder 16 is returned to the pump 10 via the valve 15; the wax in the motor 19 cools, this being facilitated by mean of fins 65, and the pump piston 17 is returned by the spring 18, thus allowing lubricant to again enter the cylinder 16; lubricant in the timing cylinder 41 is forced through a timing orifice 40, Fig. 3, to the metered injectors (not shown) by means of the piston 42 being urged by the spring 43. When the timing cylinder 41 is empty, a striker 56, carried by the piston 42, closes the microswitch (not shown) and restarts the cycle.
