Title: Automobile steering wheel with control of electric warning device
IPC: B60Q5/00
Filed: 1931-04-14
Abstract: 365,897. Hand-wheels. TURGEON, C., 25, Boulevard SevignÚ, Rennes, Ille-et- Vilaine, France. April 14, 1931, No. 10997. Convention date, April 15, 1930. [Class 80 (iv).] For operating electric warning-devices such as horns and direction-signalling lamps on motor vehicles, switch-elements comprising an annular fixed contact and a movable contact in the form of a spring ring under tension are housed in an annular recess in the steering- wheel rim, the movable contact being operable by the finger at any point in its circumference without disengaging the hands from the wheel. The movable ring may be in the form of a coiled spring 1, preferably of aluminium alloy or other light conducting metal, normally seated in a recess 3 from which it can be dislodged into a recess 5 of larger diameter to contact with a ring 4, the overhanging edge of the rim 2 protecting it against unintentional displacement. The part 4 also may be a coiled or other spring ring held in place solely by its elasticity and merely contacting with the conductor 6, but may be a plain or stranded wire or flat or other metal strip fixed in any manner, or can be replaced by an insulated metal portion of the rim itself. The ring 1 may be insulated from the driver's hands by a varnish, paint, rubber, &c. covering bared for contact. The leads 6 may be concealed in one or more hollow spokes 7 or, in the case of flexible or sliding spokes, may lie beneath the usual sheath or be in flat strip form. A single lead connected to the contact 4 may be used, the contact 1 being " earthed " to the chassis through the wheel. Selective actuation of two warning-devices may be effected by using a change-over switch mounted on the wheel or by subdividing the contact member or members into independent semicircular segments. According to the Specification as open to inspection under Sect. 91 (3) (a) the coiled spring 1 may be replaced by a circular metallic strip capable of flexure to close the circuit, or by an elastically-mounted rigid ring. This subject-matter does not appear in the Specification as accepted.

Title: Manufacture of glycerole mono-lactate
IPC: C07C69/68
Filed: 1935-04-10
Abstract: Glycerol monolactate is made by heating glycerol with a lactic acid ester of an alcohol boiling below 100 DEG  C.  The reactants in about equimolecular proportions may be heated in the presence of an esterification catalyst, the temperature being kept below 100 DEG  C. A solvent or diluent boiling below 100 DEG  C. may be present which facilitates removal of the liberated alcohol.  In an example, ethyl lactate, glycerol, benzene, and sulphuric acid are boiled together under a fractionating column, the vapours of alcohol and benzene which distil being condensed, washed with water, and the separating benzene continuously returned.  After neutralization with caustic soda, benzene is removed by distillation.  The glycerol monolactate contains a trace of sodium sulphate.  To avoid this, barium hydroxide may be used in neutralizing and the precipitate separated.  Methyl lactate may replace the ethyl ester.  Specification 346,486 is referred to.

Title: Hydraulically pressurized reservoir
IPC: B64D37/10
Filed: 1957-04-05
Abstract: 805,188. Hydraulic controls for aircraft. KORSAK, K. and TRELEMAN, L. M. April 5, 1957 [April 20, 1956], No. 11176/57. Class 4. [Also in Group XXIX] An hydraulically pressurized liquid reservoir for aircraft comprises a reservoir cylinder 28 having a piston 27 connected to a ram 29 working in a cylinder 31. Pressure liquid from a main hydraulic system is supplied through a duct 47 and pipe 45 to the cylinder 31 and acts on the ram 29 to pressurize the liquid in the reservoir cylinder. A pump (not shown) draws liquid from the reservoir through an outlet duct 34, and a branch line from the discharge side of the pump leads, through a pressure reducing valve and a duct 51 to the cylinder 31 beneath a floating piston 48. The pressure in duct 51 is slightly below that normally maintained in duct 47, but if the pressure in the main system fails, the floating piston 48 is forced against the ram 29 and the liquid in the reservoir is maintained under slightly reduced pressure. Liquid is returned to the reservoir through an inlet duct 43 which tapers to a port 44 which discharges the liquid tangentially into the reservoir. Baffles 35, 39 are disposed around the outlet duct. A swirling motion is set up by the fluid entering the reservoir, and centrifugal force causes the liquid to flow outwardly and any occlude air or bubbles to accumulate in the central portion below baffle 39. This air leaks through holes 41 and collects in an air separation chamber 42. From this chamber air can bleed off to atmosphere by automatic or manual operation of a relief valve 57.
