Title: Improvements in or relating to proximity warning devices
Inventor: VIELLE JOHN
IPC: G01S13/933
Filed: 1957-11-22
Abstract: 890,115. Transponder apparatus; radar. AVEL CORPORATON GENEVA. May 23, 1958 [Nov. 22, 1957], No. 36470/57. Classes 40(5) and 40(7). Relates to apparatus for ascertaining the relative height of an aircraft from the ground or from another aircraft. As shown, a ground station includes a transmitter 1 provided with a scanning aerial 2 which may form part of a standard radar installation. A pressure capsule 4, which gives a measure of height, or alternatively a manual adjustment 5 control a coder 3 which in turn modulates the normal radar pulses as by delaying each primary pulse by an amount characteristic of the height to be transmitted, these pulses being transmitted at a much lower power than the normal radar pulses and the separation between the strong and weak pulses being indicative of height. Normally the coder 3 is adjusted by the "offsetter" 5 to transmit a signal representative of the height at which the aircraft is expected to be, and the aircraft carries a receiver 6 which passes the coded signal to a gate 7. The height of the aircraft as measured by a pressure capsule 8 controls a coder 9. The undelayed primary pulses from the receiver 6 are passed to the coder 9 which delays them by an amount dependent upon height. If the height of the aircraft corresponds with that received from the ground station the signal from the coder 9 will reach the gate 7 at the same time as the weaker pulse received via the receiver 6 and the gate will operate a responder transmitter 10 operating upon a different frequency to that of the transmitter 1, to transmit the signal from the coder 9. The response signal is received at the ground station by an aerial 11 mechanically coupled to the aerial 2 and via a receiver 12 is passed to a gate 13 similar to the gate 7 and thence to a display device 14. If the display device is fed by the primary radar in addition, the differentiation between the reflected primary radar pulses and the transponded pulses may be made by the different intensity of the pips on the cathode ray tube. Alternatively a tube may be used having a phosphor which has a colour dependent upon the degree of excitation. Two separate display devices may be used and may be superimposed by a suitable optical system. If desired, the response may be coded with further items, e.g. call sign, course and speed, and the gate 7 biased as soon as a response transmission is initiated to prevent the gate being re-activated on the reception of the next interrogation unless the response transmission has been completed. Specifications 874,261, 874,262 and 874,263 are referred to.

Title: Combination of a hammer drill or rotary hammer drill and a a tool a plug-in adaptor and a coupling means
IPC: E21B1/38
Filed: 1977-09-01
Abstract: The tool (10) of a percussive hammer, which tool (10) can be acted upon by a percussion element (21), passes with its shank (10') through a hollow adaptor (13, 13') and is coupled to the latter while maintaining axial play. The rear end of the shank (10') is acted upon directly by the percussion element (21). Thus, compared with a known percussive hammer in which the blows are transmitted to the tool shank (10') via a rod-shaped impulse transmitter mounted in the hollow adaptor (13, 13'), functional disturbances in the axial play between shank (10') and adaptor (13, 13') are reliably avoided. <IMAGE>

Title: A new or improved apparatus for delivering measured volumes of liquid
IPC: G01F11/44
Filed: 1946-12-12
Abstract: 619,464. Delivering measured quantities of liquids. IMPROVED DESIGNS, Ltd., READ, N. K., and READ, H. L. Dec. 12, 1946, No. 36668. [Class 106(v)] Apparatus for delivering measured volumes of liquid comprises a measuring chamber, valve means for the supply and discharge of liquid, mechanism to control the said valve means while allowing of sufficient time for filling and emptying the chamber, means for setting in motion the said mechanism which then functicns automatically for the remainder of the cycle of operations and governor means for controlling the rate of operation of the mechanism. As shown in Fig. 1, depression of a plunger 22 causes cam 38 to disengage pawl 36 from ratchet wheel 35 mounted on a spindle 34 which then rotates under the force of a clock spring (not shown), mounted on spindle 30 and driving the spindle 34 through gears 32, 33. Rotation of spindle 34 turns a cam disc 39 causing a lever 42 to pivot so that its locking lug 43 engages a recess 45 in the plunger and holds the latter depressed. The spindle 34 drives a centrifugal governor 48 through a gear train 47 and also drives the pin wheel 49 of a Geneva mechanism (Fig. 4), spur wheels 54 being connected one to the inlet valve 15 and the other to the discharge valve 16 of the measuring chamber. During one complete revolution of the pin-wheel 49 the discharge plug valve 16 is turned to close and the inlet plug valve turned to open, a pause then occurs during which the measuring chamber fills, valve 15 is then closed and valve 16 opened and finally a further pause is allowed whilst the measuring chamber empties. The spindle 34 having then completed one revolution, the dwell on the cam disc 39 again registers with the end of the lever 42 which pivots away from the plunger 22, releasing the latter which returns to its original position and allows the pawl 36 to re-engage the ratchet wheel 35, thus stopping the mechanism. The capacity of the measuring chamber may be varied by insertion within the glass cover (not shown) of spacing rings, blocks, etc. Depression of the spindle 22 and consequent rotation of the spindle 30 winds the clock spring at the commencement of each cycle of operations. In a modification, the apparatus may be arranged to empty the measuring chamber on initial operation of the spindle 22, the chamber then refilling ready for subsequent use.
