Title: A measuring jacket
IPC: A41H1/10
Filed: 1961-09-18
Abstract: 922,363. Measuring for wearing apparel. F. W. R. DRAKE. Sept. 29, 1961 [Sept. 18, 1961], No. 33313/61. Class 141. A measuring device in the form of a transparent or opaque jacket is cut from cardboard, metal &c. patterns (Fig. 1) which are printed in the shaded areas with numbered graduated lines parallel to the direction of the arrowed lines. The graduated lines are transferred to the jacket material by means of parallel notches or holes using cellulose paint, printers' ink or the like. The jacket is made up by sewing or welding the component pieces and is used for measuring by placing on a figure and adjusting with paper clips to bring the appropriate graduated lines together. The original pattern can then be altered using the corresponding selected lines noted on the jacket as guides, and the actual cloth may be cut from the altered patterns.

Title: Improvements in or relating to radar apparatus
Inventor: PARKER ERIC
IPC: H01Q3/24
Filed: 1955-11-22
Abstract: 800,920. Aerials; radar. DECCA RECORD CO., Ltd. Nov. 22, 1956 [Nov. 22, 1955], No. 33496/55. Class 40 (7). A pulse radar apparatus includes differentlydirectional receiving aerials feeding to a common display selectively only signals corresponding to targets within selected range limits; or the aerial feeds have circuit means for cyclically varying the relative amplitudes of signals from the separate aerials in synchronism with the time-range scanning rate of the display; displays of targets within selected height regions are thus afforded. Aerial system.-The receiving aerials 20, 21, 22 (see Fig. 2) are horns associated with a common reflector or lens and are so positioned that the required vertical lobes (see Fig. 1, not shown) ensue. A separate transmitting aerial, or transmission from the receiving aerial system, may be used: in either case it is arranged that the transmission vertical polar diagram coverage is adequate. The beam is narrow in azimuth and the aerial system is rotated to afford a planposition (P.P.I.) display. General (see Fig. 2).-The receiving aerials connect to electronic switches 33, 34, 35 con-. trolled from sawtooth waveform generator 44 such that the range examined by a polar diagram corresponds to the selected height limit. After detection the range-limited signals are combined and fed to P.P.I. 43. The coverage pattern may be shaped in any desired manner by using appropriate switching waveforms from generator 44. Switch 50 controlled from generator 44 serves to switch signals in some recurrence periods to display 51 and at such times different range limits are imposed by switches 33 to 35 so that echoes from low-flying aircraft are shown on display 43 and from high-flying aircraft on display 51, or a single two-colour display unit may be used. The switch in the feed from the lowest-lobe receiving aerial may notch the feed to eliminate echoes between two selected ranges, e.g. an undesired ground return; this notching may be introduced on selected bearings only. More than one receiving aerial output may be notched. Alternatively low elevation echoes may be eliminated from the higher lobes by subtractive cancellation in unit 42 over the ranges in which those undesired signals occur. Modifications.-In Fig. 3 (not shown) the signals are combined at radio frequency after the switching process and one display is provided for high-, and another for low-, flying aircraft.

A double drawing block comprises a pair of adjacent and axially aligned drawing blocks, the connection between the drawing blocks comprising slipping means, and means for the supply of liquid coolant to the interior of at least one of the blocks. The apparatus comprises a frame 1 in which a shaft 4 is supported by a bearing 3. A driving gear 6 is keyed to the lower end of the shaft and a first drawing block 8 is keyed to the upper end of the shaft, and secured to it by a bolt 10, the spindle 9 of the block 8 forming an extension of the shaft 4. Mounted on bearings for rotation about the spindle 9 is a second block 12, which has an annular wall 13. Keyed to the upper end of the spindle 9 is a drum 15, which lies close to the inner wall of the well 13, and is splined externally. The outer wall of the well 13 has projections 17 facing inwardly. Stacked in the well are eight brake discs 16 which rotate with the spindle 9 and eight castiron discs 18 which rotate with the drum 12, the assembly forms a slipping clutch which is loaded by helical springs 20 and a pressure plate 19, the position of which is adjusted by a spider 21 threaded into a sleeve 22 which forms an extension of the block 12. Liquid coolant is supplied to the block 12 from a pipe 28, through channels 27, 31, 34, 35 and pipes 36 and 38 to a well formed by a wall 37 and the inside surface of the block 12. Overflow from the well drains into the block 8 through holes 39. Coolant also reaches the lower block 8 through channels 29 and 40 and is directed against the inside surface of the block by a baffle 41. Coolant drains from the block 8 along the path shown by the arrows A, through a hole 44 to a drain or storage tank. An air chest 45 surrounds the lower block 8 and directs air as shown by the arrows B on to the wire. The diameter of the wireengaging surface of block 12 is 2% greater than the corresponding surface of the block 8 and the pressure-plate 19 of the clutch is adjusted so that there is 2% slip between the upper and lower blocks and a suitable tension is maintained in the turns around the lower block. Mounted on one side of the frame is a conventional set of killing rolls and an adjustable guide pulley which guides the wire from the lower block to the killing rolls (Fig. 4, not shown).

[Also in Division G1] The density of a fluid is determined by measuring the natural frequency of vibration of a cylinder filled with the fluid. As shown, (Fig. 1A), a thin-walled cylinder 12 of magnetic material, effectively clamped at its ends by flanges 13, is located in a conduit 10 carrying the test fluid and made to vibrate at its natural resonant frequency by a driving coil 19 and pick-up coil 20 located diametrically opposite at the middle of the cylinder 12 and coupled through air amplifier 22. The oscillation frequency is indicated on a meter 24. The fluid flows inside and outside the cylinder 12 and may therefore be at a high pressure. The transducers may be adapted to fit into an elbow bend (Fig. 4, not shown), or attached to a long handle for measuring density at different depths.

A thyratron, controlled in accordance with output current and/or voltage, replaces one of the metal rectifiers in a bridge-connected network of metal rectifiers. The bridge, consisting of thyratron V1 and metal rectifiers MR1, MR2, MR3 is connected in series with a condenser C1 across the A.C. input. An amplified error signal is obtained from the D.C. output voltage tapped off Rv or output current taken off shunt Rc and fed back to the grid of the thyratron. The amplifier is a double triode, Fig. 7 (not shown). In a modification, Fig. 5 (not shown), the output of the controlled rectifier bridge is augmented by an auxiliary rectifier in parallel with it, the auxiliary rectifier being supplied from a current transformer in the A.C. supply to the main rectifier. In another modification, Fig. 6 (not shown), the output of the controlled rectifier bridge is augmented by an auxiliary rectifier in series with it, the auxiliary rectifier being supplied from an additional winding on the main supply transformer. In another modification, Fig. 9 (not shown), a current transformer in the main supply applies a transient current signal to the thyratron con. trol amplifier so as to improve stability. According to the Provisional Specification, the controlled thyratron may replace a metal rectifier in a voltage doubler, which in Fig. 1 (not shown), also has a voltage boost from a series auxiliary rectifier, in Fig. 2 (not shown), has automatic changeover from constant voltage to constant current control to provide " knee-curve " regulation; in Fig. 3 (not shown), the voltage boost is replaced by current boost; in Fig. 8 (not shown) the voltage doubler alone has transient feedback to improve stability and in Fig. 10 (not shown) the control voltage applied to the thyratron is limited by a biased diode clipper.
