Title: Improvements in anti-dazzle devices for vehicles or aircraft
IPC: B60J1/20
Filed: 1936-11-10
Abstract: 468,181. Windscreens ; roller blinds. TYLER, S. H. Nov. 10, J936, No. 30657. [Class 20 (iii)] Relates to anti-dazzle devices for vehicle windows and windscreens, of the kind comprising a flexible sheet 5 of transparent material arranged like a spring roller blind. According to the invention, the sheet is provided with projections or a transverse rod 3 adapted to engage in the notches 2 of arms 1 which are adjustably and removably connected to brackets 9 fitted to the body or roof of the vehicle. In the construction shown, the brackets are formed with slots 12 which receive the bolts 14 upon which the arms are mounted. These bolts pass also through upper or lower holes 15 in plates 13, the lower ends of which have further holes 16 for the reception of the ends of the roller spindle. The lower ends of the arms may be secured to the vehicle body by pins passing through holes 1<a>. In a modification, the brackets are each formed with a spring clip adapted, for example, to clip over the windscreen.

Title: Improvements in and relating to wire or rod grooving machines
IPC: B21B1/16
Filed: 1922-11-09
Abstract: 210,548. Butterfield, P. F. Nov. 9, 1922. Wire; nails and spikes; rods. - A machine for helically grooving rods and wires, particularly for making nails, railroad spikes and concrete reinforcements, consists of a series of cutting-discs carried on and adjacent one end of a sleeve, which is freely rotated in bearings by the longitudinal draw of the rod through sleeve and between the discs in a direction from the sleeve to the discs. The, machine as in the example shown, may be provided with drawing discs, so that the rod or wire may be drawn and grooved at one operation. The drawing-die 5, which may have holes of various sizes, is placed in a recess in the standard 3 and is positioned by a block 7 and a screw 8. The grooving is effected by four inclined discs 60 mounted on arms 62 pivoted in a head 34 which is free to rotate. The arms 62 have extensions 66 which engage a grooved enlargement 29 at the outer end of the guide-sleeve 26 through which the rod or wire 27 passes. A boss 31 on the head 34 rotates with, but is movable axially on the sleeve 26 which rotates on ball-bearings in a sleeve 45. This sleeve 45 is engaged by a ring 57 on the end of a, hand lever 56 which is movable in a vertical plane, but immovable axially. The boss 31 rotates on a ballbearing in a casing 37 which is screwed on to the sleeve 45. The lever 56 carries a double pawl which can be engaged with a ring of teeth 54 on the sleeve 45, so as to rotate it in either direction and by its screw connection with the casing 37, the latter is moved axially to adjust the position of the discs with regard to the wire and determine the depth of the grooves. The casing 37 is carried by and adjustable in a cylindrical head which is provided at each side with a horizontal trunnion so that the cutters may rise and fall freely due to irregularities in the wire. The trunnions are moutned in arms carried on vertical pivots passing through lugs and the standards 3. One of the pivots is removable so that the grooving apparatus may be swung round on the other pivot out of the way of the drawing dies. The arms are connected together by curved cross-bar passing beneath the cylindrical head. The grooving effected is of the form shown in Fig. 10, one side of each groove having a feather edge to engage the wood when a nail formed of such wire is driven causing a rotation of the nail and preventing its too easy withdrawal.

Title: Improvements in and relating to the production of white clouded enamels on iron
IPC: C03C4/00
Filed: 1937-11-10
Abstract: 494,799. Enamels and glazes. KREIDL, I. Nov. 10, 1937, No. 30823. Convention date, Nov. 11, 1936. [Class 56] A method of producing white clouded enamel for direct application to iron consists in adding to the enamel substances which, when the enamel is fired, evolve gases which are not reduced, or only with difficulty, by the carbon contained in the iron. Suitable substances are hydrocarbons of high molecular weight such as resins, pitches, tars, asphalt, or the like which are also suitable for clouding the enamel by the evolution of gas bubbles. These gas-clouding agents may be used with the addition of solid clouding agents such as tin oxide or antimony oxide. The enamel is particularly suitable for application to metal supports of the kind described in Specifications 401,650 and 421,171.

Abstract: 1,272,351. Phase comparators; phase lock loops. POST OFFICE. 30 June, 1970 [1 July, 1969], No. 31564/70. Heading H3A. [Also in Division G4] A phase comparator for producing an output signal approximating to the form where # is the phase difference between two input signals and k is a constant comprises: means for producing a signal of the form (1+k) sin #; means for producing a signal of the form 1/1 + k cos #; and means for multiplying the two signals to produce the desired output signal. The two input signals whose phase difference is to be measured are applied to mixers 1, 2 to produce signal of the form sin # and -cos #. The cos # component is multiplied by a factor k in amplifier 11, 18, Fig. 3, and then applied to an exponential stage comprising transistor 15 to produce an output from amplifier 20 which approximates to 1/1 + k cos #. This signal is applied to one input of multiplier 27, the other input of which receives the sin # signal via a potentiometer 28 which is adjusted to give the required (1 + k) factor in the numerator of the output signal The comparator may be employed in phase lock loops for recovering the carrier and bit turning in a data transmission system, in which a received carrier modulated with data is fed via a buffer 44, Fig. 4, and a X2 stage 47 to one input of a phase comparator 48 of the type described. The output from the local carrier oscillator 49 is fed via X2 stage 50 to the other input of comparator 48 and the comparator output provides the control signal to lock oscillator 49 to the received carrier. Another output from buffer 44 and oscillator 49 are applied to demodulator 55 to recover the data signal which is subsequently fed to a bit recovery circuit, Fig. 5 (not shown), comprising another phase lock loop. This latter loop omits the X2 circuits, and includes a full wave rectifier (59) in the data input path to the comparator.

[Class 83 (i)] Moulds.-In centrifugal casting the gradually increasing thickness of the cast layer is positively controlled by a barrage. The thickness of the wall of metal inside the rotating mould 1 is regulated by a vertically adjustable wall 3, roller 23, Fig. 3, or trough 13, Fig. 4. The wall 3 or trough 13 may be adjusted by tilting and the former may have recesses in its lower edge to divide the metal into bands or vary the thickness thereof longitudinally. The metal may be fed to the mould before or during rotation by means of a tilting trough 7, Fig. 3, or by a runner 17, Fig. 4, and the trough 13 which has a slot in the bottom. The mould has a lining 2 and both it and the wall 3 may have spaces 5, 6 for cooling medium. The trough 13 may move axially and the roller 23 be driven during casting. When pouring has ceased the barrage may serve to smooth the surface of the metal.
