Abstract: 1,258,082. Selective printing. CREED & CO. Ltd. 19 Feb., 1969 [22 Feb., 1968], No. 8746/68. Addition to 1,244,651. Heading B6F. In a data-printing apparatus of the kind in which each character is formed by the successive selective energization of rows of elements and in which comprises a rotating recording surface with groups of recording heads as described in parent Specification, the recording surface 1 executes more than one cycle of motion whilst recording successive lines of characters. The length of the recording surface is such that after the first cycle of motion lines are recorded on unrecorded parts of the surface between previously recorded lines. In the example shown the first character in line one comprising a selective energization of ten rows of elements is recorded in the first column and subsequent characters are staggered axially by one letter-space and around the surface of the cylinder by 0À1 inch. There are 72 characters in one line so that 7À2 inches of surface is used. The second line of 72 characters is then printed in the next 7À2 inches making 14À4 inches in all which is 0À1 inch more than the circumference of the cylinder. This means that the third line starts 0À1 inch below the first line and the whole surface of the cylinder is thus eventually used. When the surface is full, transmission stops, and the recorded surface is used to offset print the characters on to a paper.

Abstract: 1,264,956. Bandwidth compression. PLESSEY CO. Ltd. 26 June, 1969 [27 June, 1968], No. 30798/68. Heading H4R. In a bandwidth compression system the incoming speech is split into time divided sections related to the fundamental frequency of the speech waveform and a fixed proportion of the sections are transmitted, each being expanded in time, and therefore compressed in frequency, to occupy the entire input signal duration. The processing is carried out digitally. At the receiver the incoming sections are compressed in time and repeated to fill the gaps provided by the time compression. In the bandwidth compressor, Fig. 1, audio signals at terminal 1 are applied to an A.G.C. circuit 4 to make the signal level substantially constant and then to an analogue to digital converter 7, e.g. a delta modulator, which provides digital signals at a pulse rate determined by generator 8 to feed to a first shift register 9, which is stepped at the same rate as the input signals. Periodically, at times determined by the fundamental frequency of the input signal, the entire contents of the shift register 9 are transferred in parallel into the register 13 from which they are fed out in series at a rate with a fraction, e.g. “ of the rate of stepping of the first register 9, and determined by the divider 14. To determine the instant of transfer of the contents of register 9 to register 13, the output signal of register 13 is converted to analogue form in d to a converter 14 and filtered to provide the fundamental frequency at the output of filter 15. This signal provides an enabling input to a bi-stable trigger 16 which is triggered by a coincidence circuit 17 when the outputs of d to a converters on both registers are of the same amplitude and slope. The bi-stable circuit when triggered causes monostable circuit 18 to generate a pulse which closes all the switches S to transfer the contents of register 9 into register 13. The output signal may be transmitted in digital form, as at terminal 2 or analogue form, as at terminal 3. At the receiver, Fig. 2, the incoming signal feeds into a first shift register 9<SP>1</SP> at the divided pulse generator output rate and is transferred to the second shift register 13<SP>1</SP> by operation of switches S<SP>1</SP> when the amplitude and slope of the register outputs are similar at the end of each fundamental frequency period in a similar manner to that used at the transmitter. The shift register 13<SP>1</SP> will normally contain more than one complete fundamental frequency period but only one complete period is required to be recirculated to provide continuous undistorted speech. Recirculation of one period is achieved by the - staticiser 26 under the control of a shift register 27 which is reset at the commencement of each period by the pulse from monostable 18<SP>1</SP> and shifts a pulse through its stages under the control of the pulse generator 8<SP>1</SP> until a second transfer pulse occurs from monostable 18<SP>1</SP> when the staticiser closes the appropriate one of the switches SF and the register 27 is reset to its initial condition again.

Abstract: 1,266,976. Turbine, compressor and ducted fan rotors. GENERAL ELECTRIC CO. Aug.27, 1969 [Sept.3, 1968], No.42739/69. Heading F1T. A turbine or compressor or ducted fan rotor having angularly spaced blades projecting radially therefrom comprises a hoop formed of circumferentially-extending filamentary material and a circumferential yoke portion which embraces the inner surface of the hoop and has radially extending flange portions on opposite sides of the hoop. The blades are secured to both said flange portions. The rotor 18 shown in Fig. 1 is the ducted fan rotor of a gas turbine ducted fan engine, the rotor comprising a yoke member 24 formed with lateral flanges 27 also with an inward projecting flange 26 by which it is secured to a frustoconical driving flange 14 and to a frusto-conical flange 20 of a fairing cone 22. The driving flange 14 is secured to a drive-shaft 12 by a nut member 15. A hoop member 42 formed of filamentary material is disposed within the yoke member 24 and a rim member 28 is secured to the yoke member by diffusion welding the internal flanges 29 of the rim member to the flanges 27 of the yoke member. The rim member 28 is formed with arcuate dovetail section grooves 30 in which the root portions of the fan blades 32 are mounted. Platform members 36 are disposed between the blades and the blades are secured in position by a flange member 38. The internal surface of the rim member 28 is grooved at 31, the groove intersecting the blade mounting grooves so that openings (33) are formed whereby the welding of the flanges 27, 29 may be inspected. The yoke portion and the rim portion are formed of homogeneous material such as beryllium, whereas the hoop member 42 is formed of bonded filamentary material such as boron or carbon. In operation, radial loading is taken as tension loading through the yoke and its flange portions, the radial loading being ultimately carried as tension loading by the hoop. In Fig.4 the yoke member 24 is formed in two halves each integrally with part of the rim portion 28 and with a semi-circular groove (48) which upon assembly receives the hoop member 42. The parts are dimensioned so that upon assembly the parts of homogenous material are pre-stressed in compression. An axial flow compressor rotor comprising a series of blade stages is similarly formed, Fig. 6 (not shown), the blade roots being mounted in circumferential grooves formed between the co-operating yoke and rim portions.

As shown, squeezing the chamber 10 increase the pressure in the liquid so that the float 24 rises within the diving assembly housing 20 to compress the gas 14: the diving assembly 13 accordingly sinks. Upward movement of the housing 24 in the diving assembly 13 pivots the two claws 21, to which it is connected about a transverse rod 34 across the housing 20, to the open position shown dotted. By tilting the chamber 10, the diving assembly 13 can be directed to alight upon suitable booty on the floor of the chamber. On release of the chamber 10, the decrease in liquid pressure allows the float 24 to slide down inside the housing 20, the claws 21 pivot inwards to grip the booty, and the diving assembly 13 rises in the chamber 10. As shown, the float 24 has axial spacing ribs 29 along its length, and an oil, and seal 30 along its base. In a modification, Fig. 6 (not shown), the lower part of the float is of frusto-conical shape.

Abstract: 1295210 Strapping machines FMC CORP 25 Oct 1971 49476/71 Heading B8C In a strapping machine, a strap 36 from a supply, not shown, is formed into a loop having overlapping strap portions, the overlapping portions are moved sideways, the loop is tightened around an object and severed from the supply, and a new loop is formed whilst the overlapping portions of the first loop are being secured together. The strap 36 is fed from the supply by a feed roller 38 and is guided into a loop-forming guide 16 by a track 28 formed in a reciprocable shuttle 24 and a slot 32 formed in a member 20. When the leading end 36<SP>1</SP> of the strap 36 leaves the guide 16, it is guided through a channel 26 in the shuttle 24 and into a space 22 formed between the member 20 and a slidable anvil 18 to abut a switch 40. This abutment energizes a solenoid which causes a latch 70 to release a lever 58 which carries the shuttle 24 so that the shuttle is moved to the left by a coil-spring 74. Thus the strap 36 is moved into a slot 82 formed in a strap gripper 80 whilst the leading end 36<SP>1</SP> enters a space between the gripper 80 and the anvil 18. The switch also energizes a motor which rotates a cam-shaft 54 which causes the gripper 80 to rise and hold the leading end 36<SP>1</SP> of the strap against the anvil, and the motor is then stopped. An object is then placed on the anvil 18 and the roller 38 is reversed to withdraw the strap from the guide 16 and tighten the loop about the object, the roller 38 then being halted and the cam-shaft motor re-energized. Thus a second gripper 92 rises to engage the leading end 36<SP>1</SP> and a blade (38, Figs. 7-10) adjacent the gripper 80 severs the strap 36. Thus a new leading end (36a, Figs. 5, 6, 9 and 10) is created and is located within the slot 82. Whilst the loop is being secured, the shuttle 24 is moved back to its initial position by means of a cam 66 so that the new leading end (36a) enters the slot 32, the roller then being energized to advance the strap around the guide 16. When the overlapping strap-portions have been secured, the anvil is retracted so that the loop snaps against the bottom of the object.
