Title: Improvements relating to type composing machines
Inventor: MOYROUD LOUIS MARIUS
IPC: B41B27/28
Filed: 1963-03-25
Abstract: 1,041,053. Type-composing machines. INTERNATIONAL PHOTON CORPORATION. March 20, 1964 [March 25, 1963], No. 11733/63. Heading B6W. Justifying type.-Apparatus for accumulating line length information comprises a keyboard, a conductor corresponding to each character leading to means for calculating relative character width, and means for multiplying the relative width by the set size. The means for calculating relative width comprises an array of columns and rows of magnetic memory devices. A conductor from a type face selector switch is threaded through each column of magnets, while each character conductor is threaded through the one magnet in each column corresponding to the relative width of the character in the corresponding type face, each row of magnets corresponding to a given width and having an output conductor threaded through all the magnets therein. In operation, depression of a character key closes a contact in the circuit of the corresponding conductor and thereafter closes a universal contact, whereupon a pulse generator sends a current through the character conductor and the selected type face conductor. In the case of the magnet situated in the selected type face column and in the correct width value row, the current from both selected input conductors passes through it, and the sum of the currents is strong enough to energize it and produce a pulse on the output conductor. The multiplying means comprises a similar array of magnets, one set of input conductors leading from the relative width calculating means outputs and the other set leading from a series of set selection switches, the output conductors being energized so as to commence a binary counter transmitting information as to the product of the relative width and the set size, i.e. the actual width in the composed line. Each input conductor representing a relative width is in this case threaded through one or more magnets in each column to give the correct product in binary form. If the point set has not the same nominal value as the set size, the multiplying means is additionally controlled by circuit responsive to the type face and the point size. The relative width calculating means and the multiplying means each comprise one or more interchangeable plug-in cards, referred to as " style cards " and " set cards". In another form, the magnets in both arrays are actuated to assume "0" and "1" states by currents of selected polarity passed through the column inputs, followed by a positive current passed through the selected width input. Magnet resetting means are provided. The magnets may be replaced by resistance-diode "AND " circuits.

Title: Improvements in or relating to radar systems
Inventor: BRANDON PERCY SAMUEL
IPC: G01S13/26
Filed: 1955-04-25
Abstract: 915,160. Radar. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Jan. 19, 1956 [April 25, 1955], No. 11827/55. Drawings to Specification. Class 40 (7). In a frequency modulated C.W. radar system, the frequency of a transmitter-reflex klystron oscillator is saw-tooth modulated, but only a part of the frequency spectrum is transmitted during each cycle. The range beat notes obtained at the receiver are higher than those derived in a normal system due to the higher rate of change of frequency at the present transmitter. The beat rates, which arrive in bursts, are analysed by either a multi-analyser or a known sweeping spectrum analyser. The selection of the part of the output frequency spectrum of the transmitter oscillator is effected by an amplifier klystron, between the oscillator and the transmitting antenna, which is switched on and off alternately by the frequency locking pulse train controlling the saw-tooth generator. A carcinotron may be employed instead of the reflex klystron. The receiver is of conventional form. Two forms of multi-analyser are shown, in the first of which a bank of range analysing filters are followed by range gates operated from a delay line and which each feed into a block of narrow band filters to extract the Doppler frequencies in case of moving targets. In the second multi-analyser, the range analysing filters are sequentially connected to the receiver by a rotating switch.

Title: Improvements in milling and like machines for copying and reproducing
IPC: B23Q35/10
Filed: 1934-04-19
Abstract: 417,709. Milling-machines for copying. BRISTOL AEROPLANE CO., Ltd., and WHITEHEAD, F. W., Filton House, Bristol. April 19, 1934, No. 11878. [Class 83 (iii).] In a machine for milling from a templet the sleeve valves or cylinder barrels of internalcombustion engines or other parts, the feed mechanism, operated through a friction coupling serves to drive both the work relatively to the tool and the tracer relatively to the templet, the feed being limited by the engagement of the tracer with the templet. The work-frame 10 carries a rotatable work head 11 on which the cylinder barrel 12 is located by pins 13, a rim 40 of the head being supported in a ball-bearing 22. The other end of the work 12 is supported by a plate 14 held against the work by a screw 43. The ports 45 in the part 18 of the cylinder barrel are cut first from the inside and then from the outside of the cylinder. For cutting from the inside, a cutter head 19, Fig. 2, or an arm 20 carries a cutter 21 driven through bevel gearing. A templet ring 23 having holes 24 corresponding to the ports required in, the work is secured to the head 11 by screws 63, and is engaged by a tracer pin 25 mounted in an adjustably fixed bracket 27. A member 34 secured to a sleeve 32 grooved to receive a member 37 fitted with friction material 38 engaging a rim 40 of the head 11. The member 34 is oscillated by a connecting rod 41 driven from gearing 51, 52. The work piece 12 is first provided with a drilled hole to receive the milling cutter 21 and in operation the frame 10 is continuously traversed longitudinally of the work by a screw feed. In addition, the member 34 continuously oscillates the work to an extent determined by the engagement of the tracer pin 25 with the hole 24 in the pattern ; the friction coupling slipping to allow the further movement of the member 34. When the pin 25 reaches one end of the hole 24 in an axial direction the longitudinal movement of the work carrier is reversed until the other end of the hole is reached. For cutting externally, Fig. 4, the cutter head 19 is outside the cylinder barrel. The wall of the port may be inclined to a cylinder radius by using a suitably shaped milling cutter, but to vary the obliquity according to the longitudinal position of the barrel, the cutter head may be controlled by a cam 58 engaged by a roller 56 secured to the cutter head and held up to the cam by a spring 59. The outer part of the port may be enlarged as shown at 66.

Title: Improvements in or relating to dies for wire-drawing or other purposes
IPC: B21C3/18
Filed: 1925-05-08
Abstract: 245,654. Wade, H., (Cyclo Corporation). May 8, 1925. Compound metal forms; dies.-A die for wiredrawing, punching, &c. is made by bringing tungsten associated with a hardening agent to molten condition and consolidating the same with a metal supporting body such as steel. A wiredrawing die is made by first preparing a body A, Fig. 1, of steel &c. A bar 3 of tungsten associated with a hardening agent is introduced into the bore 1, the body is placed into a water-cooled electrode B and another electrode C is applied to the upper end of the tungsten bar. When the tungsten is melted, a pointed water-cooled tool C<1> is brought down and caused to cool and mould the tungsten, and as the latter solidifies, increasing pressure is applied by the tool to consolidate the tungsten with the die body. The melting and consolidation of the tungsten are effected in an inert atmosphere. The die is then drilled and the surface of the bore is lapped or ground, e.g. by inserting a tool, applying heavy pressure, and effecting relative rotation between the tool and die. Graphite, soap-stone, &c. may be charged into the pores of the metal at the operative part of the die during this process. A shell of tungsten associated with a hardening agent may be applied to a steel punch &c. by using an annular electrode. Boron, silicon, or a mixture of carbon, boron, or silicon or of any two of these may be used as a hardening agent in the place of carbon. The die-body may be composed of iron and carbon or of iron carbon and silicon, in which case a billet of pure tungsten may be employed. A method of preparing a tungsten-carbon bar is described.
