Title: Oscillation generator particularly designed for polyphonic musical instruments
IPC: G10H3/20
Filed: 1962-12-03
Abstract: 979, 240. Electrophonic musical instruments. MATTH.HORNER A.G. Dec. 3, 1962 [Dec. 1,1961], No.45604/62. Heading G5J. In an electrophonic musical instrument, a mechanical oscillator element such as a reed 16 is deflected from its normal rest position by a finger 11 on a key when the key is unoperated. Depression of the key releases the reed and allows it to vibrate. A rubber member 12 on finger 11 carries a damper-pad comprising a layer 14 of soft rubber or foam and a thin outer layer 15 of leather. The outer layer 15 may be coated with a tacky adhesive so that the reed is plucked as the key is depressed. The keys are mounted on pivots 3. The white keys 1 are spring-biased against a stop 10 with a soft contact surface 9. The black keys 2 are biased against a soft contact surface 6 on a buffer strip 7. The vibrating reed generates an electrical signal in either an electrostatic or an electromagnetic pick-up. The voltage generated by a reed depends upon its amplitude of vibration and therefore upon the touch or impulse imparted to the key. Electrostatic pick-up. An electrode 22 common to a group of notes is mounted in a slot 21 in a non-conducting base 20 and is itself slotted at 22a Fig. 2 to form a section opposite each reed 16. An adjustment can be made for each individual note by bending the section with a screw. The electrode section adjacent the tips of the reeds may be terminated as shown in Figs. 4, 5 or 6. A circuit is described (Fig. 7 not shown). Electromagnetic pick-up. Reeds 65 to 68, Fig. 9, which may be of stainless steel, are arranged with their tips adjacent magnetic pole shoes 55 to 62, Fig. 8, mounted in a groove 63 in a non-magnetic base plate 64. The pole shoes are wound as shown with more turns linked with the pole shoes associated with reeds of higher frequency. The windings are connected through a transformer 70 and amplifiers 71, 73 to a loudspeaker. Specification 809,853 is referred to.

Abstract: 1368294 Vehicle tracks CATERPILLAR TRACTOR CO 1 Oct 1971 [20 Nov 1970] 45888/71 Heading B7C  A generally rectangular track shoe 23, for an endless track assembly intended to be mounted around a resilient toroidal spacer means 21 (e.g. a pneumatic or air-bag tyre), comprises a generally flat inner surface 37 intended to contact the spacer means in use, first and second lugs 33, 34 formed on respective longer edges of the shoe, and anti-slippage means, e.g. 35, extending longitudinally of the shoe and projecting from the inner surface 37 of the shoe so as to dig into the spacer means in use and thereby prevent slippage of the track assembly circumferentially relative to the spacer means. In the Fig. 2 embodiment the anti-slippage means is constituted by the free edge 35 of the lug 34, which latter is curved as shown. The Fig. 2 embodiment may be modified (Fig. 8, not shown), by providing additional anti-slippage means in the form of a circular-section rod welded to the inner surface intermediate the longer edges of the shoe. In further embodiments the lug 34 is flattened and the anti-slippage means is then provided by one or, as shown in Fig. 7, two circular section rods 35c, 35c<SP>1</SP> welded to the shoe between its longer edges or by a protrusion (35a) (Fig. 4, not shown) located approximately midway between the longer edges of the shoe and formed integrally with the shoe. In all of the above-described embodiments the shoe may be provided with grousers 31, 32 extending longitudinally of the shoe on its outer, ground-contacting, surface. A plurality of the shoes 23 are coupled together to form the track assembly by means of substantially annular linkages located in use adjacent respective side walls of the spacer means 21 and each consisting of links 25 secured, e.g. by bolts 29, one along a shorter edge of each shoe, each link having a fork portion 27 which receives a blade portion 28 of an adjacent link and is coupled thereto by a pivot pin 26. In use, the lugs 33, 34 of the shoes overlap one another as shown in Fig. 1 so that the tread 36 of the spacer means 21 is completely masked and ingress of dirt and the like between the spacer means and track assembly is prevented. The spacer means and track assembly may be selected such that the ratio of the height of the anti-slippage means to the thickness of the tread 36 of the spacer means is in the range 0À1-0À5, and the ratio of the said height to the distance P shown in Fig. 2 is in the range 0À027-0À186. Specifications 1,320,532 and 1,368,293 are referred to.

Title: Improvements in and relating to apparatus for compressing or expanding a fluid medium
IPC: F02G1/053
Filed: 1964-11-12
Abstract: 1,082,581. Pistons. PHILIPS'GLOEILAMPENFABRIEKEN N.V. Nov. 12, 1964 [Nov. 15, 1963], No. 46135/64. Heading F2T. [Also in Division F1] The compression ratio of a reciprocating -piston machine, e.g. an expansion engine, a hot gas engine or a compressor, is varied by hydraulically adjusting the position of an auxiliary piston 22 relative to a main piston 23. In the compressor shown, liquid is pumped at 38 to the space V between piston 22, 23. An overflow tube 43, spring-loaded to abut the crown of piston 22 until a flange thereon abuts piston 23, determines the maximum spacing between the pistons, the overflow liquid then returning to the crank-case. Liquid also returns to the crank-case past a deformable annular seal 56 surrounding piston 23 and having an outer diameter smaller than the cylinder bore. A guide rod 41 and spring 42 ensure that the pressure difference across a rolling diaphragm seal 26 is sufficient to maintain the same in a stretched condition. When the pressure in a buffer space 36 in the compressor discharge pipe 35 exceeds a certain limit, a diaphragm-operated valve 50 opens, and liquid returns to the crank-case from space V via pipe 39, a second and normally open diaphragmoperated valve 44 and pipe 55 to reduce the spacing between the pistons and thus the compressor delivery. When the pressure across the rolling diaphragm 26 reaches its lower limit, the valve 44 closes. Further leakage from space V past the seal 56 is prevented when the skirt of piston 22 abuts an annular plate 57 and deforms this seal so that it engages the cylinder wall.

Filed: 1973-10-05
Abstract: 1406003 Rolling mills T SENDZIMIR 5 Oct 1973 [5 Oct 1972] 46577/73 Heading B3M A planetary mill for rolling strip 1, Fig. 1, has platens 8, 81 arranged to modify the paths of the work rolls in the roll nip from a circular orbit to a more flattened path. The platens are each positioned on the opposite side of a respective backing roll 5 or 5<SP>1</SP> from the roll nip, and cause modifications in the work roll paths by slightly deflecting the backing roll. The platens are backed by beams 9, 9<SP>1</SP> of the mill housing, and are movable by wedges 11, 11<SP>1</SP> to vary the roll gap. The contour of each platen 8 (top portion of Fig. 3) has slight protuberances 8c, 6e and 6g and depressions 8d and 6f. As the rolls opposite those in the nip follow this contour, the rolls in the nip itself are deflected slightly from their circular orbit; thus the angle x at which the roll strikes the strip 1 is reduced from angle y, and the roll path from R to Q follows a straight rather than arcuate path. The mill includes feeding rolls 2, 2<SP>1</SP> which perform a reduction on the strip, and further guide rolls 3, 3<SP>1</SP> and 4, 4<SP>1</SP>. The rolls 4, 4<SP>1</SP> are pivotable about a common fulcrum 14 by rods 15 and 15<SP>1</SP>. The rolls 3, 3<SP>1</SP> deflect the strip from its normal pass line to improve its straightness, and one of the rolls 3 may be withdrawn from the strip to minimize heat loss. A heater 18 having resistors surrounded by quartz tubes, high temperature burners, or eddy current generators, is located between the feed rolls 2, 2<SP>1</SP> and the work rolls 6.

Abstract: 1,241,057. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 2 Oct., 1968 [19 Oct., 1967], No. 46759/68. Heading H1K. A high conductivity N type zone in a device formed in a body of monocrystalline semiconductor material having a face parallel to a 100 crystallographic plane has a surface concentration of phosphorus of 2À5 to 4 x 10<SP>3</SP> parts per million by weight. This is achieved without significant precipitation of phosphorus due to the low dislocation density in thus aligned material. A junction isolated transistor (Fig. 2) in a typical solid circuit embodiment is formed on a 10-20 ohm. cm. P type silicon wafer 30 cut from a crystal grown along a 100 axis with its faces in a 100 plane. Subcollector region 32 is formed by diffusion and extends during epitaxial deposition of N-type epitaxial layer 34. A grid of isolation walls 37 is next diffused in prior to formation of base 38 and emitter 40 by successive diffusions. Alternatively region 32 is formed by ion implantation or etch and refill steps. Aluminium, platinum or palladium contacts 42 are formed by vapour deposition overall followed by pattern etching in a nitric-phosphoric acid mix. The diffusions are all effected through holes formed by conventional photolithographic techniques in thermal oxide layers. Arsenic is the dopant in regions 32, 34, boron in 37, 38 and phosphorus in the collector. The decline in current gain # with falling collector current is far less than in an otherwise identical device formed on a 111 orientated substrate. Manufacture of an oxide or nitride passivated planar epitaxial transistor (Fig. 1, not shown) with a phosphorus doped emitter and of an enhancement mode IGFET with N+ phosphorus doped source and drain regions is also described. The IGFET has a lower threshold voltage than its 111 orientated counterpart.
Patent GB-470728-A (GB)
Abstract: 470,728. Zeroizing - mechanism. TRIGGS, W. W. (Underwood Elliott Fisher Co.) Aug. 10, 1936, No. 21950. [Class 106 (i)] The pinions of a totalizer which may be actuated in both directions (for addition or subtraction) are zeroized by rotating the shaft on which they are mounted, the shaft having a slot with the edge of which pawls carried by the pinions engage during zeroizing but during normal entering operations a control member arranged in the slot moves to prevent this engagement. Pawls 54, Fig. 3, are pivoted inside the totalizer pinions 8, and are pressed by springs 55 on to the shaft 48. During zeroizing, a control member 56 is moved to the bottom of a slot 51 in the shaft 48 and this shaft is then rotated, the edge 52 of the slot 51 thus engaging the pawls 54 and zeroizing the pinions 8. Zeroizing is effected by the manual rocking of a lever 30, Fig.- 1, about its pivot 32, the first movement being anticlockwise. The end of the lever is formed as a cam 44 which restores the known transfer mechanism and which releases an arm 68 connected to a pair of arms 62, Fig. 2, which are then rocked anticlockwise by a spring 64. The arms 62 normally engage the ends 57 of the control member 56 and maintain it in the position shown in Fig. 3, When the arms 62 are rocked by the spring 67 consequent upon the operation of the zeroizing lever 30, springs 58 push the control member 56 to the bottom of the slot 51 so that the edge 52 of the slot can engage the pawls 54. By this time a pin 33 on the lever 30 has picked-up a segment 31 engaging a pinion 49 secured to the shaft 48 whereby this shaft is rotated to effect the zeroizing. During entering operations the end of one lever 62 projects through a slot 63a in the pinion 49 into the bottom of the end part 53 of the slot 51 in the shaft 48, thus locking this shaft.
