Abstract: 792,527. Type - bar - making machines. LINOTYPE GES. May 31, 1956 No. 16916/56. Drawings to Specification, Class 100(3) In a record-strip-controlled typographical composing machine, means is provided actuated by a selected code combination of stopping the record-reader feed and sensing machanism so as to interrupt the operation of the machine escapement mechanism to allow the manual insertion of special matrices, and a member which can be actuated at will is provided for re-starting the machanisms. On sensing of the selected signal, one of the reeds operated in the normal way closes a switch, to operate an electromagnet and open the feed and sensing mechanism clutch, and to close circuits to visual and audible signalling devices indicating that the mechanism has been stopped. The key lever associated with the particular reed is operated to re-start the mechanisms by opening the switch, or can be used independently of the code signal to close the switch and stop the mechanisms.

IPC: G01R27/26
Filed: 1968-04-10
Abstract: 1,192,485. Capacitance measurement. SOC. D'INSTRUMENTATION SCHLUMBERGER. April 10, 1968 [April 13, 1967], No.17367/68. Heading G1U. To measure a capacitance C x , the capacitance is connected into a differentiating circuit incorporating the operational amplifier G2 and feedback resistors R 1 , R2 which is fed with periodic sawtooth signals, the slopes of the sawtooth signals being accurately known. The differentiating circuit produces an output related to C X , which output is passed via rectifier and filter circuits to a digital voltmeter. The sawtooth waveform is produced by using square wave signals from a generator 10 to switch on, alternately, transistor switches TI1 and TI2 so that signals from voltage sources - Vr and + Vr are passed alternately to the integrating circuit 14. This circuit incorporates an input resistor Ro, operational amplifier G1 and feedback capacitors. Range changing is achieved by switching between the feedback capacitors Ce1-Ce3 while at the same time changing the frequency of the signal generator 10. With a sawtooth input voltage, derived using capacitor Ce1, the differentiating circuit provides an output at H with a peak to peak voltage given by 2RIC X  /Ce1 where R is the mean of R 1  and R 2  and I = Vr/Ro. This is proportional to C X , and is rectified and smoothed via diodes D1, D2 and circuits C1R1, C2R2 to provide a direct voltage (between J1, J2) corresponding to C X , which is measured by the digital voltmeter 16.

Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1938-06-11
Abstract: 515,755. Slicing-machines. FITZPATRICK, H. J. (Maatschappij van Berkel's Patent N.V.). June 11, 1938, No. 17390. Addition to 464,649. [Class 28(ii)] In a slice-stacking mechanism for a slicing- machine, the connection between slice-discharge fly and the shock-absorber comprises an arm which turns with the fly and is linked to a guide movable with the shock-absorber, and the fly is operable under the control of a cam working in timed relationship with the slicing-machine and acting on said lever. As shown, the fly 1 has a pivot shaft 2 to which is secured an arm 4 urged upwardly by a spring 5 in a telescopic casing 6. A link 10 connects the arm 4 with a roller guide 20 carried by the upper end of the plunger rod 19 of a dashpot 18 similar to that described in the parent Specification. The roller 20 rides against a stationary track 21. The action of the spring 5 on the fly is resisted by a roller 16 on a bell-crank or other lever 13 bearing against a rotary cam 11, until the lever 13 reaches the cam-drop 11a. The fly is then swung in the direction of the arrow A, the consequent upward movement of the arm 4 being resisted by the dashpot, the rod 19 of which is pulled upwards. As the roller 20 rides along the track 21, the link 10 turns towards a position in which it would be perpendicular to the track,- and therefore the resistance to the movement of the fly is progressively increased until the fly is brought to rest. The cam 11 slowly returns the fly and other parts to their initial positions against the action of the spring 5.

Abstract: 234,318. Woude, D. van der. June 3, 1924, [Convention date]. Heating buildings.-Relates to hot water heating-systems for buildings &c. of the kind such as is described in Specification 156,829, in which the admision of water to the radiators is controlled by adjustable valves or throttling devices, and the water is discharged by a return pipe 6 into an open tank 7, from which it is delivered by a pump 8 to the boiler or heater. In order to avoid constant manipulation or adjustment of the throttling devices as the supply pressure varies, the water, before entering the radiators 4, is conducted into one or more intermediate chambers 9 at a high level in which an approximately constant pressure is maintained. In the arrangement shown in Fig. 1, which is suitable for a system including a large number of radiators, several intermediate chambers 9 are provided, each of which is open to the atmosphere and the level of water therein controlled bv a float valve 10, while the supply of water to the radiators is controlled by valves 12 arranged in the outlet pipes from the radiators. Additional valves 13, 14, 15, 16 are provided for placing out of operation or draining individual radiators or the entire system. In a modification, Fig. 2, which is suitable for a single dwelling, the boiler 1 is replaced bv a heating coil 18 arranged in the single intermediate chamber 3. The heater may also be arranged between the chamber 9 and the radiators, and the chamber 9 may be in the form of a closed tanh in which a constant pressure above that of the atmosphere is maintained.

Title: Method of diamond drilling
IPC: C04B41/53
Filed: 1943-10-26
Abstract: 580,411. Drilling diamonds &c. CALLITE TUNGSTEN CORPORATION. Oct. 26, 1943, No. 17655. Convention date, June 26. [Class 83 (iii)] [Also in Group XXIII] Holes are drilled in diamonds, corundum, &c. by the aid of a high-frequency electric current. The diamond to be drilled is prepared by lapping two parallel flat faces. Two additional parallel faces are lapped and polished at right angles to these in order that the contour of the hole being drilled may readily be examined. The diamond is then centred in one side as by use of a diamond splinter, making a small conical hole a, Fig. 2. The centred diamond 1 is placed on a glass plate 2 in a glass cup 3 and is just covered with an electrolyte such as nitric or sulphuric acid, an electrode 5 is introduced remote from the diamond and a driven spindle 6 carries a tungsten needle 7. A variable highfrequency generator 12, on closing the switches 14, 14a, delivers a power output of about 100 watts at from 350 to 1500 volts at a frequency of 25 kilocycles to 20 megacycles. Control of the contour of the holes is effected by shaping the needle and by changing the size of the needle. After a conical cavity a has been drilled part way through, the diamond is turned over and spotted on the other side in exact axial alignment with the first formed hole and a second conical hole b is drilled, drilling being discontinued some time before breaking through into the first hole. The diamond is now dried and supported on a glass plate 28, Fig. 4, and tungsten needles 23, 26 connected to high-frequency spark coils 21, 24 are engaged in the cavities. The needle may be fixed or rotated. Step-up transformers 33, 40 supply the coils at from 10,000 to 30,000 volts. The hole c resulting is finally polished and may be of diameter as small as 0.00025 inch.

A moulding-machine comprises a head having a wall 27 forming an open cavity closed by a flexible diaphragm 34 which may be moved into engagement with moulding-material in a flask 19, the area of the diaphragm being substantially greater than the cross-sectional area of the mould-box, and exceeding that necessary to conform to the surface of the moulding material, so that no tension results in the diaphragm when in the moulding position. The flask is carried on a vertically-movable support 13 and the diaphragm is forced into engagement with the sand by pressure-fluid supplied through a valve 3a to a chamber 25 in the head, connected to the cavity behind the diaphragm by holes 28 in the wall 27. Between moulding operations, the diaphragm is held up in the head-cavity by suction applied to the chamber 25 through a valve 38. In a modification, Fig. 5, chambers 74, 75 and pressure-fluid connections 84, 85 serve to inflate the side portions of the diaphragm to ensure that the edges of the sand in the flask are firmly packed. In a further modification, Fig. 6, the diaphragm 103 is of accordian type.
