Title: Improvements in or relating to brakes for motor-driven vehicles
IPC: B60T1/06
Filed: 1919-09-01
Abstract: 154,976. Faire, J. H. C. Sept. 1, 1919. Disk.-In a motor-vehicle brake of the multiple-disk type, the driven disks 5 have projections 15 fitting in grooves 14 in the drum 2 on the axle 1, and the stationary disks 6 have projections 16 engaging grooves 17 in the oil-tight casing 12. The disks are pressed together to effect braking by a fork 11, which is operated from a pedal to slide the end plate 8 along the axle 1. The drum 2 may carry the driven wheel 18. Reference has been directed by the Comptroller to Specifications 1297/85, 28145/02, 11723/03, 16959/04, [all in Class 80, Mechanism &c.], and 13911/07.

Title: Improvements in or relating to shaft tubbing
Inventor: MOHR FRITZ
IPC: E21D5/10
Filed: 1957-07-09
Abstract: 815,878. Making shaft segments. VERUSCHACHT VEREINIGTE UNTERTAGUND SCHACHTBAU G.m.b.H. July 9, 1957, No. 21661/57. Class 83 (2). [Also in Group XXI] Shaft tubbing made of rolled steel, comprises tubbing segments formed from rolled sections with peripheral internal flanges produced integrally with the webs by the rolling. Tubbing segments comprise a rolled section, e.g. lightweight alloy steel, having integral flanges 1 with root fillets 3 and a web 2. The segments are quenched at the rolling temperature and tempered by the dissipation of residual heat during further cooling. The tempering is increased, particularly at the fillets by the additional residual heat caused by the accumulation of material there. Straight sections may be tempered after rolling and subsequently curved by coldworking. The tempering may also be done independently of the hot-working of the sections. The joint between the ends of segments may be a butt-weld or alternatively a jointing strip 6, Fig. 4, may be used, the flanges of the strip being recessed into the flanges 1 of the segments. When using jointing strip, sealing rods 10 of an impermeable material are inserted in grooves 8, 9. In another modification the segments are provided with end flanges by folding up excess lengths 11, Fig. 7, of the web and if required welding, soldering or bolting the end flange to the peripheral flanges 1. The ends of the vertical flange 11 may be pressed to form a good jointing surface 12. In a further modification separate plates may be welded or bolted to the segments to form end flanges.

Title: Improvements in or relating to modulated carrier wave transmitters
IPC: H03C3/30
Filed: 1936-08-06
Abstract: 460,426. Modulating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 6, 1936, No. 21719. Convention date, Aug. 16, 1935. [Class 40 (v)] In a carrier wave transmitter, phase modulation is effected in successive cumulative stages. As shown in Fig. 1, the carrier wave source 1 feeds successive amplifiers 3, 3<1> and the output is taken through an amplitude limiter B and further amplifiers or frequency-multipliers A to an aerial 10. The signal from a source M is applied to the grids of valves 9, 11 the plate circuits of which are respectively coupled by an inductive coupling 18, and a capacity coupling 141 to the respective output circuits of the carrier amplifiers 3, 3<1>. The variation in plate impedance of the valve 9 causes a phase shift of the carrier current in the circuit 13, and this variation is emphasized in the circuit 13<1> by the action of the valve 11. Other forms of coupling may be employed between the circuits 13, 13<1> and the plate circuits of the valves 9, 11 ; and variation of the coupling. controls the degree of modulation. In Fig. 3, the first stage of phase modulation comprises two amplifiers 27, 28 with their inner grids energized in phase quadrature by the output of a preliminary amplifier 23 fed from the carrier source 1. Other grids in each valve are fed in phase opposition from a signal source J through a transformer 17. The plates of the two valves are joined, with the result that the carrier energy in the tuned plate circuit 29 is phase modulated. A further similar stage 42 of phase modulation follows.

[Classes 83 (ii) and 83 (iv)] The power press described in the parent Specification is modified by transmitting motion from the main shaft to slides operatively connected to the horizontal and lower vertical tools. The means of connection is preferably adjustable to enable the tools to be brought into operation simultaneously or at different times and for varying periods. As shown, a main shaft 8, with the usual crank and link 10 operating the upper slide 11 and tool 11a, carries gear wheels 12, 13 with crank pins 12a, 13a attached to rods 14a, 14b connected to slides 15a, 15b. The latter carry pivoting pins for tubes 17 connected to arms 18 fixed to the ends of rock shafts 19, provided with cranks 19a. Links 20 are mounted on the cranks and are connected to tool carrying members 21. Loose keys 22, provided on the underside with teeth, are arranged in slots in the arms 18, and mesh with teeth on the rock shaft 19. Freeing the keys enables adjustment of position of the arms to vary the stroke or time of operation. Similar construction enables the same result to be obtained for the lower tool.

Title: Improved process for making iron-silicon alloys
IPC: C21C7/00
Filed: 1935-07-31
Abstract: In a process of making iron-silicon alloys containing 15-16 per cent of silicon, pig iron is dephosphorized by means of lime, and desulphurized and deoxidized by means of ferromanganese with the addition of lime and barium oxide.  The carbon content is then adjusted to 3 per cent by the addition of potassium ferrocyanide, and degasification is effected by means of ferro-titanium and magnesium. Ferrosilicon, preferably containing about 94,8 per cent of silicon, is then added, in admixture with petroleum coke, in such quantity as to secure the desired silicon content in the product, followed by an addition of potassium cyanide and petroleum coke, a final degasification being effected by means of magnesium and calcium.  In some cases 0,1-0,2 per cent of boron, in the form of ferro-boron, may be incorporated in the alloy.
