Title: Improvements in or relating to means for attaching persons or packages to parachutes
IPC: B64D17/38
Filed: 1919-12-01
Abstract: 159,948. Crozier, W. H. Dec. 1, 1919. Hook fastenings.-A parachute for use on aircraft is connected by two cables, one over one side and one over the other side of the fuselage, to two links secured in automatic releasing means on the aircraft, the person using the parachute being connected to a member which is also secured in automatic releasing-means and provided with two hooks, one or the other of which automatically engages the corresponding link of the parachute as the person leaves the aircraft to one side or the other. The parachute is connected by cables 1, 2 to links 3, 4 secured inspring clips 6 - - 9 on a fitting bolted at 12 to the aircraft. Spring clips 13, 14 on the fitting secure a member 15 provided with two pivoted hooks 16, 17 which are normally retained in the position shown by springs 18. A link 19 connected to the person is pivoted to the member 15 and has a roller adapted to engage either of the hooks 16, 17 as the link 19 is pulled to one side or the other as the person leaves the aircraft, the hook ultimately being drawn into and held in engagement with a pin 5 on the adjacent link 3 or 4. The member 15 and appropriate link are then pulled out of their clips and finally the other link is released. The hooks 16, 17 have tailpieces 20, 21 so that when one hook is closed the other cannot be closed and when the load comes on the device the closed hook cannot open until the load is removed. Means may be provided to prevent removal of the member 15 until one orthe other of the hooks has been brought into engagement with its link. For this purpose a stop on the cable connected to the link 19 may engage the forked end of a normally vertical lever which is swung sideways into a position enabling the cable to be withdrawn as the appropriate hook is brought into engagement with the link 3 or 4. Alternatively, a plate anchored to the main fitting may have a flange concentric with a pivot of the link 19, a horn on the link engaging the flange which is sufficiently long to prevent withdrawal of the member 15 until a hook has engaged its link.

Title: Improvements in and relating to honing, grinding and lapping tools
IPC: B24B33/08
Filed: 1950-12-07
Abstract: 682,126. Grinding cylindrical workpieces. MICROMATIC HONE CORPORATION. Dec. 7, 1950 [Feb. 6, 1950], No. 29969/50. Class 60. A tool for grinding, honing or lapping the external cylindrical surface of a workpiece 21 comprises a body 51, arms 33, 35 in the body crossing each other at an angle, and means cooperating with the arms at their point of crossing for adjusting them longitudinally. Grinding, honing, or lapping elements 15, 17 of stone, lead, copper or cast iron are secured in holders 27 which can be adjusted to the diameter of the workpiece against scales 47 on the arms 33, 35 and clamped by screws 43. In order that the pressure between the elements 15, 17 and the workpiece may be adjusted along radial lines spaced apart preferably by substantially 120 degrees, the ends 65, 67 of the arms slide in slots in the housing 51 which are parallel to these radial lines, rollers 69 being provided in the body to facilitate the sliding movement. Recesses 75, Fig. 7, are formed in the ends 65, 67 of the arms to engage the oppositely-inclined parallel surfaces 85, 87, Fig. 6, of a cam 83 which, when moved relatively to the recesses 75 by a screw 89, Fig. 1, pinned thereto, slides the arms in the body. The screw 89 is moved by rotating a nut fixed axially against movement and provided with a knurled head 105 and a skirt having an adjustment scale 107. The tool, which may be hand-held, has a non-abrasive guide element 13 housed in the body and may be pivoted between centres 135, 139, Fig. 9, from a sleeve 125 carried rotatably by a standard 123 fixed to the table of a drilling machine or the like. In this event the workpiece is rotated and fed by the drill chuck. More than three work-engaging elements may be provided if desired.

Title: Improvements in or relating to vestigial sideband transmission systems
IPC: H03C1/60
Filed: 1965-07-15
Abstract: 1,049,358. Vestigial sideband reception. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 15, 1965 [July 17, 1964], No. 30010/65. Heading H3Q. A receiver for a vestigial sideband transmission with added low-frequency signal (see Specification 1,031,596) has a balanced modulator 1 in which the incoming signal is combined with the recovered carrier, the latter being obtained from a further balanced modulator 7 in which the low-frequency components of the demodulated signal C are combined with the incoming signal. The output data signals are taken off at 3a after passage through a low-pass filter 2 and squarer 3. The recovered carrier injected at 1b comes from a limiter 9 and oscillator 8, the latter being controlled by the balanced modulator 7 to follow the frequency and phase of the recovered carrier signal. Assuming the sideband fully transmitted extends to 1À8 kc/s. from the carrier and the vestigial sideband to 0À5 kc/s., the incoming signal is limited by a filter 5 to a signal extending symmetrically to 0À5 kc/s. on each side of the carrier; the characteristics of this filter are complementary to the vestigial sideband filter used in the transmitter. The filter 4 which selects the low-frequency components of the demodulated signal has a phase characteristic of the same shape, as that of filter 5, and it is shown mathematically that this results in the recovered carrier being of the correct phase and frequency, and of maximum amplitude. A limiter 6 after the filter 5 generates some odd harmonics of the carrier; any spurious output due to these is removed by the low-pass filter 2.

Title: Self-adaptive timing system for a traffic controller
Inventor: CRESS VERNOR BERT JR
IPC: G04F10/04
Filed: 1968-06-24
Abstract: 1,214,063. Road signals for controlling traffic. TAMAR ELECTRONICS INDUSTRIES Inc. 24 June, 1968, No. 30067/68. Heading G4Q. In a traffic control system having a green signal 19 and a preset timer 25 establishing a minimum green period, control means is provided including a vehicle detector 11 for detecting vehicles approaching the signal when it is not green, a timing counter 55, and a scaling counter 40 so coupled between the vehicle detector and the timing counter as to provide a fixed plurality of pulses to the timing counter 55 for each vehicle passing the detector when the signal is not green, and a source 62 of clock pulses arranged to count the timing counter 55 back to a datum setting to establish a variable timing period which terminates when the datum setting is reached and means for maintaining the signal green for the two periods consecutively. When a green signal control 20 maintains the green signal off the signal via inverter 36 enables gate 34 to pass a single pulse 12 for each vehicle detected by detector 11. The pulse 12 resets a scaling counter 40 such as a ring counter including bi-stable flip-flops and activates a bi-stable circuit 42 output No. 1 to ON. This enables a gate 43 to pass signals from a H.F. pulse generator 50 to the counter 40 and a bi-directional timing counter 55. Both counters count up the pulses from 50 and when a predetermined stage such as 5 is reached the output 50 resets the bi-stable 42. This disables gate 43 and prevents further pulses from 50 being countered by either counter 40, 55. The next vehicle detected similarly restarts counter 40 and adds further pulses to counter 55 so that the number of pulses counted by counter 55 represents the number of vehicles waiting during the stop and amber periods. When the green signal control connects the power source 21 to the green signal it also sends an enable signal to gate 63. This allows pulses from a clock pulse source 62 to pass to the bi-directional counter 55 to drive it down to zero. The preset timer is inhibited from its timing operation by the output from gate 65 when one or more of the output stages of the counter 55 is not zero or when the green signal 19 is not being held on by the green signal control. When the counter 55 reaches zero the timing operation of the preset timer starts and the green signal continues until the end of this pre-set period. The green signal may be kept on after the pre-set period by virtue of vehicle actuation on the green street. If the bi-directional counter 55 becomes full an inhibit signal is fed to gate 43 to prevent further supply of pulses 47. The gates 34, 43 and 63 may be electronic gates using diodes or transistors and gate 65 may consist of semi-conductor circuits. The traffic controller 20 may be as disclosed in Specification 1,154,131.

Abstract: 1,122,479. Evaporators; flash type; desalination of water. WESTINGHOUSE ELECTRIC CORP. 30 June, 1967 [2 Sept., 1966], No. 30322/67. Heading BIB. In an evaporator comprising a series of flash chambers 1, 2, 3, each of which communicates with a condensing chamber containing heat-exchange tubes, progressively lower pressures are maintained in the successive chambers and air and other non-condensible gases are removed from the evaporator by means of a vapour-operated ejector 61, the outlet of which is connected to the suction inlet of a liquid-operated ejector 62. As shown, the evaporator is used for the desalination of sea, river or lake water; the ejector 61 is operated by steam, and ejector 62 is operated by water. A stream of water is forced by pump 75 into the inlet of ejector 62, and draws in the mixture of steam and gases exhausted from ejector 61. The steam is condensed in the raw water, and a mixture of the hot water and gases flows into apparatus 87, where sulphuric acid is added in order to decompose carbonates. The mixture then flows into container 76 where the liberated gases are discharged through vent 84. The de-aerated water is pumped via line 88 through the heat-exchange tubes in stages 2 and 1 of the evaporator, and then through heater 49 into the first flash chamber 1. As the water flows through the chambers, part of it flashes into steam which is condensed on the heat-exchange tubes. A stream of the raw water is pumped through the heat-exchange tubes of stage 3 of the evaporator, and is then returned to source. A portion of the brine in flash chamber 3 is discharged through line 55, and the remainder is recirculated, together with makeup water from line 88. Distilled water is withdrawn through line 59. The water-level in container 76 may be automatically maintained at a predetermined level by a level-sensing device connected to a valve in line 88. Chambers 1, 2, 3 may be formed by a metal housing structure. Pump 75 and container 76 may be made of plastic material. The apparatus may be used to distil a solvent, other than water, from a solvent; in which case ejector 62 is operated by the solution, and ejector 61 is operated by the vapour of the solvent.
