Title: Dictating machine
Inventor: BLAISE ROBERT ERNEST
IPC: G11B5/00
Filed: 1962-03-05
Abstract: 936,786. Belt recorders. DICTAPHONE CORPORATION. March 5, 1932, No. 8443/62. Class 40 (2). A portable stylus recorder using the same size of belt as the larger office-type recorder described in Specification 910,739, achieves compactness by housing the batteries in the belt-mandrels 60, 64; battery contacts 210, 220 are arranged as seen in Fig. 3. The lid portion 16 of the case, when swung back 90 degrees swings the rear mandrel 60 forward on the mounting 62 so that a belt can be loaded or unloaded, closure of the lid tensioning the belt; a rim 67 on the mandrel 64 forms a loading end-stop and any eccentricity of the mandrel 64 causing variable depth of cut during recording by the head 188 is compensated, during playback by the pick-up 170 by arranging the circumference of the belt to be a whole multiple (3x) of the circumference of the mandrel 64. The belt-driven mandrel 64 is started by a hand-microphone button (Fig. 1, not shown), which energizes a solenoid 82 associated with a clutch 80, a gear-train from the mandrel driving a lead-screw 74 which, in turn, drives a carriage 70 carrying the transducers and means 46 for marking the usual dictation direction slip mounted on the lid (Fig. 1, not shown). A record/neutral/playback lever 32 engages appropriate transducers and actuates record/ playback switching 206. Only when a lug 38 has entered a notch 36 (carriage fully to the left, Fig. 3) and the lever 38 is at " neutral " (both styli withdrawn) can a knob 40 be pressed to release the lid 16.

Title: Improvements in or relating to process for the preparation of alkaryl sulfonic acids
IPC: C07C309/31
Filed: 1955-03-25
Abstract: Alkaryl sulphonic acids are prepared by reacting an aromatic hydrocarbon with an olefin having 8-18 carbon atoms in the molecule in the presence of an alkylation catalyst at an elevated temperature and isolating the crude alkylation product therefrom, extracting the alkylation product with sulphuric acid to form two phases, the first comprising the sulphuric acid with the colour and odour precursors dissolved therein and the second consisting predominantly of the alkylation product, separating the phases, treating the second phase with an alkali to neutralize any sulphuric acid contained therein, fractionally distilling the second phase to recover therefrom a purified alkylation product and sulphonating this by the process according to Specification 804,346.  Specified aromatic hydrocarbons and olefins are benzene and toluene and polymers of ethylene, propylene or butylene. Specified alkylation catalysts are aluminium chloride, sulphuric acid, sulphonic acids, hydrogen chloride or fluoride, boron trifluoride, zinc chloride, activated bleaching earths and phosphoric acid and the preferred alkylation temperature is from 100 DEG  to 160 DEG  F.  The amount of sulphuric acid used in the acid treatment may vary from 1 to 25 per cent and its concentration may vary from 80 to 100 per cent.  The alkalis used to neutralize the alkylation product are sodium or potassium hydroxides. In examples benzene is alkylated with dodecene in the presence of aluminum chloride, the catalyst sludge is separated, the crude alkylate is agitated with sulphuric acid, the alkylate phase is separated, neutralized with aqueous sodium hydroxide, fractionally distilled under reduced pressure and the purified dodecylbenzene is sulphonated by the process disclosed in Specification 804,346.

Refrigerating, vacuum processes for; concentrating liquids by freezing.-In concentrating aqueous liquids, or evaporating water in vacuo, in apparatus wherein the liquid is cooled sufficiently for the separation of ice or crystals, the liquid is passed down a tower 1 connected to a tower 2 down which an absorbent for water vapour such as glycerine, phosphoric acid solution or sulphuric acid is passed. The towers 1, 2, are maintained under vacuum by a pump 3 and liquid is discharged from them either by barometric pipes or by pumps. The liquid disoharged from the tower 1 is raised by a pump 4, passed through a filter 10 to separate ice &c. and returned to the tower. The absorbent from the tower 2 is returned to it by a pump 5 after passage through a coil 11 cooled by trickling water over it or by immersion in water. A part of the absorbent is regenerated by passage through a packed tower 12 up which gases of combustion or exhaust gases from an internal-combustion engine pass. A coil through which water is circulated may be placed in the tower 2 to cool the absorbent. The tower 2 may be replaced by an ejector which acts simultaneously as an absorber and a vacuum pump.

Abstract: 1,163,922. Measuring speed by radio and sound waves. SANGAMO WESTON Ltd. 3 March, 1967 [3 March, 1966], No. 9444/66. Heading H4D. In a system for providing a warning on each of several vehicles moving along a defined way (e.g. a road) of its approach to another vehicle, each vehicle transmits a rearward beam of radio or sound waves on a predetermined frequency, waves from the forward direction are received, and a Doppler beat signal is derived to effect the warning. In an embodiment centimetre waves are utilized and an audible warning is given. The transmitted energy may be pulse or amplitude modulated. When sound waves are employed, a filter rejects road noise. The modulation may be coded to identify different classes of vehicles. Obstructions, e.g. bridges, are provided with a transmitter radiating towards oncoming traffic. The warning signal may be visual. Beat signal amplitude indicates distance between vehicles.

Filed: 1973-02-27
Abstract: 1368558 Bottle filling device HORIX MFG CO 27 Feb 1973 [22 March 1972] 9469/73 Heading B8T A container filling device has a filling tube 1 and a hollow nozzle 3 formed of concentric porous walls 8 and 9 spaced apart to form a chamber 10. In one form the walls 8, 9 comprise screens of fine mesh and are supported by a pair of vertical struts 13, Fig. 4 (not shown), which join an end wall 11 and a threaded ring 12. When liquid is delivered under pressure the spacing between the porous side walls reduces the velocity of the liquid and makes the pattern of flow smoother so that pressure can be increased without foaming and bottles can be filled more rapidly. An outer vacuum tube 6 has the lower end spaced above the nozzle to remove excess liquid during the filling operation. In a modified version of the nozzle the inner side wall may be a hollow porous metal cylinder (15), Fig. 5 (not shown), made from sintered metal powder.
