Title: Improvements in or relating to adjustable tables
Inventor: ARTRU ANDRE
IPC: A47B9/08
Filed: 1955-06-15
Abstract: 770,833. Releasable fastenings. APPLICATIONS INDUSTRIELLES DU TUBE. June 15, 1955, No. 17318/55. Class 44. [Also in Group XIV] A table top 22 is supported by a tube 4 sliding inside a tube 1 attached to a base 23 and provided with internal threading or grooves 2, the tubes being releasably engaged by the engagement of ball. bearings 10, carried by a member 9 associated with the tube 4, with the threading or grooves 2, release being effected by the lowering of a tumbler 13 acted on by a strong spring 16 tending to lock the ball-bearings in position and a relatively weak spring 15 controlled by a lever 19, the spring 15 being of such strength that the tubes are still locked together if there is an appreciable weight on the table when lever 19 is operated. As shown in Fig. 1, a spring is welded to the inner wall of tube 1, thus forming the internal threading, while a bearing 5 is welded to the bottom of tube 4 and carries a rotatable cylinder 9 having holes formed therein along a line identical in pitch and direction'with the spring forming the threading 2, a ball. bearing 10 being loosely mounted in each hole. Radially resilient strips are formed in a sleeve 11 and urge the ball-bearings outwardly. A central rod 14 slides in tube 4 and extends below it carrying at its lower end a tumbler 13, normally, under the action of a spring 16, bearing against the resilient strips. When a lever 19, pivoted to the underside of table top 22, is operated, the action of the spring 16 is nullified and a weaker spring 15 releases the tumbler 13 from abutment of the resilient strips. This permits raising or lowering of the table top unless there is considerable weight on it, in which case the pressure on tube 4 is transmitted through the bearings 5 and radially through the resilient strips against the ball-bearings, preventing accidental displacement of the table top. A simpler form of the invention is shown in Fig. 4, in which the lever construction is modified and the internal grooves in the outer tube are simply circular recesses.

Title: Improvements relating to analogue to digital converters
Inventor: SEABROOK JOHN GRAYHAM
IPC: H03M1/00
Filed: 1961-05-16
Abstract: 967, 671. Electric selective signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 15,1962 [May 16, 1961],No. 17817/61. Heading G4H. [Also in Division H3] In an analogue-to-digital converter, in which pulses are fed to a counter for a time period proportional to the analogue sample quantity, a recurrent sweep voltage and the sample voltage are both applied to an amplifier the input A to which has upper and lower limit clamping devices, D3, D4, and a feedback such that the input voltage tends to assume one of the limiting values, and to change from one to the other when the sweep voltage reaches the sample value thereby producing an amplified output pulse which terminates or starts the time period. In Fig. 4, sample and sweep voltages are D.C. restored to be position and negative respectively, and applied through cathode follower valves Vl, V2 and resistors R5, R6 (a) to the input of a pentode amplifier V3 the output of which is fed through a cathode follower valve V4 &c. to a differentiating circuit C2,R15 5 preceding a blocking oscillator and also (b)to a resistor chain R7,R8,R10 associated with input clamping diodes D3,D4. At the beginning of the sweep, diode D3 conducts and clamps input A. As the sweep voltage approaches the sample voltage in magnitude, the voltage of input A tends to fall until diode D3 ceases to conduct, when a fall takes place which is amplified and fed back to make diode D4 conduct thereby clamping input A against further fall in voltage. The amplifier output rise consequent to cut-off of diode D3 is differentiated and triggers the blocking oscillator to produce a pulse which is delayed and then resets a gating pulse generator. This terminates a gating pulse which was allowing counting pulses to enter a binary counter and which was initiated at or soon after the start of the sweep by a delayed timing pulse. The blocking oscillator pulse also closes an inhibit gate through which the delayed timing pulse passes, so if the sample voltage is too small, the inhibit gate will be closed when the delayed timing pulse arrives and no counting will take place. To prevent overrun of the counter an AND gate receives counter outputs and resets the gating pulse generator if necessary.
