Title: Invention relating to data processing systems
IPC: G06F11/16
Filed: 1961-09-20
Abstract: 982, 582. Digital electric calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 20, 1961 [Dec. 23, 1960], No. 33719/61. Heading G4A. A circuit gates data from a register to a logical circuit, specifically a parallel binary adder, only when it receives signals indicating that the data in the register is valid and the logical circuit is cleared. The apparatus described in the Specification operates simultaneously on the true and complement forms of a bit. Fig. 2 shows an arrangement in which a bit is entered at terminal 178 and its complement at terminal 180, is passed to storage stage N, processed in logic circuits 158, 160, and then released to storage stage N + 1. The circuits shown have two outputs, a lower, true, output and an upper, complement, output. AN, A p  circuits are and gates,-Ap circuits are minus-and gates which pass a negative signal on the lower output only when all the inputs are negative, V N  are exclusive-or circuits, and C N  circuits are inverters. The initial setting of trigger N sends the complement output of or-circuit 202 positive, the output of and-circuit 204 negative. The logic circuits are assumed flushed (or cleared) and there are negative outputs from circuits 172, 176, resulting in negative true and positive complement outputs from # 222. These are respectively applied to minus-and gates 212, 220 producing a positive output from the latter. That complementary signals have been applied to the input terminals is checked at # 214,and that the setting of storage stage N is complementary to the input at terminal 180 is checked at # 216. All inputs to circuit 212 are now negative and its resultant negative output is inverted to produce a positive true output from orcircuit 202. And-gate 204 now produces a positive output. Gates 186,188 are closed and gates 162, 174 are opened. A similar process is carried out at storage stage N + 1. Gates 190 and 192 are initially open to pass the processed bit to the store. When it is ascertained that the store is set correctly and that the next data processor (not shown) is ready to receive the contents of the store, circuit 220 produces a negative output which switches triggers 200 on and trigger 198 off. Another bit can then be applied to terminals 178, 180. A 4-bit parallel adder having true and complementary bit inputs is described with reference to Figs. 6 to 10 (Fig. 8 only shown), and follows the pattern of operation shown in Fig. 2. Storage stage N is comprised of eight triggers, the logic circuit is the four parallel single order adders and stage N + 1 is an output register of four triggers. Carries ripple through from the lowest order adder. Each adder sums true and complement representations of the input bits, first at and gates 634, 636 to produce if possible an immediate carry for the next order adder, and at # 638, and then at and gates 640 to 654 where the in-carry is taken into account.

Abstract: 414,266. Valve circuits for wireless reception. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Dec. 2, 1933, No. 33929. Convention date, Dec. 12, 1932. [Class 40 (v).] In a wireless receiver a tuned circuit L C has its damping varied periodically and is followed by a detector which produces a higher harmonic of the damping frequency. The damping may vary sinusoidally and be obtained by a valve M connected in parallel with the circuit having means to vary the internal resistance of the valve periodically, as shown, by a generator g. The harmonic frequency produced is amplified by the valve MF and detected to produce the signal. In a modification a reactive coupling is caused to vary periodically to produce the variation in the damping of the circuit by means of an alternating voltage of the damping frequency applied to the grid of the reacting valve.

Title: Improvements in and relating to vibration transmitting systems
IPC: G10K11/24
Filed: 1947-12-24
Abstract: 647,005. Transmission systems for mechanical vibrations. SPROULE, D. O., and HUGHES & SON, Ltd., H. Dec. 24, 1947, No. 34287. [Class 118 (ii)] [Also in Group XL (b)] In a vibration transmitting system comprising a metallic strip for transmitting mechanical vibrations, the direction of vibration being normal to the surface of the strip, the strip is supported by threads, e.g. nylon, inclined at an acute angle to the direction of vibration to minimise absorption of the vibratory energy by the supports. By suitably dimensioning the strips the velocity of propagation may be made dependent on the frequency, i.e. the system is dispersive, and the system may then be used for compressing the duration of a wave pulse in which the carrier frequency varies during the pulse as described in Specification 604,429. The strip may be straight/or spiral-shaped but in the embodiments described space is conserved by winding it into a helix H which is supported from an outer cage of bars B parallel to the axis of the helix and attached to annular members D, the support comprising nylon threads F looped round each turn of the helix and round pegs P mounted on the bars, the single continuous thread associated with any one bar forming a mesh in a plane perpendicular to the surface of the strip and the elements of the mesh being inclined at an acute angle to the direction of vibration V, i.e. the normal to the surface of the strip. In order to prevent axial movement of the helix, adhesive is applied at the points of contact of the thread and strip to prevent relative movement. Alternative arrangements of the supporting threads are illustrated in Figs. 4 and 7 (not shown), the embodiment shown in Fig. 4 providing greater axial stability. In order to prevent reflection of the transmitted energy at the points of support, each supporting mesh may be duplicated, the spacing between the individual meshes of each pair being #/4, Figs. 5 and 6 (not shown). In Fig. 8 (not shown) a plurality of coaxial helices are connected in series, the planes of the supporting meshes being equally spaced. In any of the embodiments the vibrations may be initiated and detected by electromagnetic transducers El, E2 coupled to opposite ends of the strip. If required, the supporting threads may run inwardly to frame members within the helix.

A fastening device comprising a stud member 22 including a stem and a shoulder 32 extending laterally from the stem, and a fastener member 25 consisting of a sleeve portion 38 with a head having an annular clamping surface 36 facing the sleeve portion, the bore 40 of the sleeve portion along substantially the whole of its length having a smaller transverse dimension than the shoulder and extending through part of the fastener member, the fastener member being of a resilient material and of a shape such that the end remote from the head can be forced on to the stud member past the shoulder, the bore of the portion thus being enlarged so that the surface of the bore is contoured to accommodate the shoulder, the sleeve portion contracting behind the shoulder so as to resist subsequent separation of the fastener member from the stud member. In the construction shown the stud member is welded to a panel 26 and to facilitate this it is provided with an initially pointed end. The shoulder is formed by an enlarged end portion 34 which is tapered to facilitate entry into the bore of the sleeve portion 40. The head of the fastener member 25 can be recessed in its under surface instead of being flat as shown. The enlarged end portion of the stud member instead of having a planar shoulder as shown can have a shoulder which is formed by a pair of helical cam surfaces which enable the fastener member after it has been axially applied to be further tightened by turning it so that the cam surfaces pull it on to the stud member. Instead of having an enlarged end portion the stud member can be made so that the shoulder is the end surface of a groove.

Title: Improvements in and relating to cutter tools of the insertable blade type
IPC: B23C5/24
Filed: 1932-09-29
Abstract: 405,440. Tools and tool-holders; milling-cutters. O. K. TOOL CO., Inc., 233, Broadway, New York, U.S.A. Sept. 29, 1932, No. 34994. Divided on and addition to 386,324. [Class 83 (iii).] In a modification of the inserted-blade cutting tools described in the parent Specification, the blade is secured to the locking member by interengaging serrations and the locking member is secured in a recess in the body by ribs and grooves extending transversely to the serrations. In another modification, serrations are provided on the blade, the locking member and on one side of the recess, and the recess is tapered or dovetailed. In one form a blade 3, Figs. 1 and 2, for a side milling cutter has a serrated face 4 engaging a serrated face 5 on a locking member 6, the blade and locking member being tapered in a direction parallel to the serrations so that the two together conform to the shape of the recess 2 in the cutter body 1. A rib 7a on the opposite face of the locking member 6 engages one of a number of grooves 7b on the adjacent side of the recess, radial adjustment of the blade being effected by engaging the rib with a different groove and axial adjustment by changing the engagement of the serrations 4, 5. The ribs and grooves may extend both radially and axially as shown, or in one direction only. In a face milling- cutter the serrations and taper of the blade and locking member extend axially and the rib and groove connections 7a, 7b are arranged radially. In a combined side and face milling-cutter the blade and locking member are each tapered in two directions and the serrations may extend radially, axially or diagonally in either direction, the rib and groove connections being preferably arranged transversely to the serrations, as shown in Fig. 7. In this modification, radial and axial adjustment of the blade are effected simultaneously. In further modifications in which the blade and locking member are each tapered in two directions, the wider end of the blade or locking member is arranged towards the axis of the cutter so as to have a dovetailed effect and in a further modification of this form the rib and groove connections are replaced by serrations 4<1>, 5<1>, Fig. 17, similar to the serrations 4, 5 and extending in the same direction, a gib 8 being then provided on the locking member 60b to engage the end of the blade 30b.
