Abstract: 207,783. Demoulin, A. F. Dec. 2, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Axles.-The back axle of a Ford car is carried on the road wheels by means of ball bearings 7 situated between each wheel hub and a sleeve 1 fixed to each end of the axle casing 2. The differential shafts 4 rotate in phosphor-bronze bearings 5 in the sleeves 1. The wheels are braked by means of steel spring bands 14 acting on the exterior of drum 13 to which flanges 9 enclosing the ball bearings 7 are secured. The brakes are held off by means of springs 16 and are applied by the rotation of shafts 17 having cams 24 coacting with stationary cams 22. Arms 24 on the two shafts 17 are connected to gether by a cable, and the two brakes are applied simultaneously by means of an eye sliding in this cable and connected to a pedal operating the usual foot-brake. The usual internal brake blocks 25 may remain.

Abstract: 1,033,505. Transistor switching circuits. SPERRY RAND CORPORATION. May 2, 1963 [May 16, 1962], No. 17348/63. Heading H3T. Variations in current through the load connected is the output of a switching transistor, due to variations in impedance of the load are corrected by feeding back to the base of the transistor through a further transistor a voltage derived from an impedance in the emitter circuit of the switching transistor. In Fig. 2, when transistor Q3 is rendered conducting, transistor Q2 also conducts energizing the coil 10 of a printing hammer. A resistor R2 in series with the coil applies a voltage to a transistor Q1 such that if the resistance of the coil 10 rises with changes in temperature any resulting decrease in current is offset by the voltage fed back from resistor R2 to transistor Q1. Transistor Q3 is operated by a bi-stable circuit Q4, Q5 in response to coincident " Set " pulses. In a modified circuit (Figs. 3 and 4, not shown), the collector of transistor Q1 is returned to the collector of transistor Q3 instead of to its emitter so that Q1 is non-conducting when Q3 is non-conducting. In addition, resetting of the bi-stable circuit is effected through a further transistor connected to the collector of Q4.

Abstract: Olefines having the double bond between the second and third carbon atoms (referred to as 2-olefines) are separated from hydrocarbon mixtures containing iso- or branched chain olefines in which the branch is attached to a carbon atom at the double bond (referred to as tertiary olefines) by treating the mixture to polymerize the tertiary olefines, and treating the remaining hydrocarbons (preferably after removing the polymerized tertiary olefines) with strong sulphuric acid to produce acid sulphate esters, the solution being then diluted to an extent such that the original acid would be reduced to 50-65 per cent strength, the diluted solution being then heated, preferably under reflux to liberate 2-olefines.  It is stated that 1-olefines are absorbed and then liberated as 2-olefines.  The sulphuric acid initially employed in the second step may be of 55-70 per cent strength, the temperature and time of contact being chosen so as to polymerize the tertiary olefines without polymerizing or absorbing the 1- and 2-olefines, and for the second stage 70-90 per cent.

In the bending and subsequent tempering of glass sheets, e.g. for. vehicle windscreens, a fragmentation barrier of untempered or only slightly tempered glass is formed by means of a temporary screen over a portion of one face and another temporary screen over a registering portion of the other face, but at least one of these screens is arranged to become effective only after the sheet has become bent. In the form shown the screen 8 is carried bv the skeleton concave mould 2 on to which the sheet 1 sinks on heating and this is the screen that becomes operative after the other, 9, which is in contact with the sheet all the time and moves with it. The screens may comprise strips, e.g. of foil which may be temporarily adhered to the glass and the strips need not extend fully to the edges of the sheet. The top screen may comprise two narrow strips spaced apart somewhat, the width of the strips plus the space then being equal to that of the under screen. Alternatively the barrier may comprise an annulus separating central and surrounding tempered zones. Specification 818,377 is referred to.
