Title: Gravimetric detector for gas chromatography
Inventor: THORBURN SAMUEL
IPC: G01N30/62
Filed: 1961-11-24
Abstract: 982,590. Gas analysis. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 23, 1962 [Nov. 24, 1961], No. 42017/61. Heading G1B. A detector for a gas chromatographic column 1, comprises means e.g. a cell 6 to absorb one or more components of a sample as they emerge from the column 1, the resulting change of mass of the cell 6 representing the mass of the or each component or of one or more selected components of the sample. The column 1 may be of "C elite" (Trade Mark) with 10% ethylene glycol or "Carbowax" (Trade Mark), and nitrogen may be introduced through an entry 2 to serve as a carrier gas. The sample is injected through an entry 3 and the gases pass to a baffle 5 disposed in the cell 6, which is supported on a balance 8. The baffle ensures that the gas flow does not affect the weight readings and the sample gases are successively absorbed by a lining of glass cloth 7 impregnated with concentrated sulphuric acid in the cell 6. As each component leaves the column 1 it causes the weight of the cell 6 to rise giving an indication of the proportion of each constituent in the sample. The balance is preferably an automatic recording balance. In the embodiment shown in Fig. 3 the effects of the gas flow are cancelled out by making the absorptive member in two parts and introducing the gas flow at its centre, the member being supported on a balance extension 24. The effect of the gas flow may be further counteracted by a similar gas flow from a part 26 and cooling gases may be introduced through parts 25. If the effect of gas flow is not important then the gas may be simply directed on to an absorptive member (Fig. 2 not shown).

Title: Non-linear electrical filters
Inventor: JEWELL PHILIP ALFRED
IPC: H03K9/06
Filed: 1959-12-14
Abstract: 923,551. Non-linear networks. MINISTER OF AVIATION. Dec. 14, 1960 [Dec. 14, 1959], No. 42395/59. Class 40 (8). [Also in Group XL (c)] A low - pass filter is shunted by a circuit having a more rapid response than the filter and designed to override the output of the filter whenever a predetermined parameter of the input rapidly changes by more than a predetermined amount. In the circuit of Fig. 2 rapid changes in the amplitude of the input give rise to an overshoot in the output voltage or to a finite rise time depending upon the resistance of the inductor 6. To obviate this, the inductor is bridged by oppositely-poled diodes 12, 16 connected in parallel and biased by batteries 14, 18 to conduct when the voltage across the inductor equals or exceeds the peak noise voltage. Thus the greater part of any sudden large change in input voltage is transmitted to the output without delay by virtue of the short-circuit which exists across the inductor for large voltages. The batteries may be eliminated if diodes or combinations of diodes requiring minimum forward operating voltages are used.

Title: Multi-component semiconductor network and method for making same
IPC: H01L21/761
Filed: 1967-09-19
Abstract: 1,201,246. Semi-conductor device. TEXAS INSTRUMENTS Inc. 19 Sept., 1967 [30 Dec., 1966], No. 42538/67. Heading H1K. In order to achieve a high degree of isolation between individual components in an integrated circuit formed in a single body of semi-conductor material, the individual components are separated by pairs of junctions between semiconductor material of high resistivity and opposite conductivity types. The components are situated within isolated regions of highresistivity N-type material distributed within a substrate of high-resistivity P-type material. The resulting junctions between the highresistivity materials exhibit high breakdown voltage and low capacitance and so provide effective isolation between the components. A high-resistivity (10-15 ohm. cm.) P-type silicon substrate 12 has epitaxially deposited thereon an N-type silicon layer 14 of similar resistivity. The surface of the layer 14 is covered with a resist 16 having apertures therein through which pockets 22, 24 are etched from the layer 14 by means of a suitable etchant. A thin layer of low-resistivity (0À018-0À02 ohm. cm.) N-type material 26, 28 is deposited epitaxially within each pocket and the remaining volume within each pocket is then filled epitaxially with less heavily doped N-type material 30, 32 (resistivity 0À18-0À22 ohm. cm.). The individual components of the integrated circuit are then formed by conventional diffusion processes within the regions 30, 32; a transistor is formed within the region 30 and the low resistance layer 26 serves as a connecting lead for its collector. A resistor is formed in region 32. In addition apertures (42) are formed in the mask (40) used during this diffusion process so as to separate each of the regions 30, 32 and acceptor impurity is diffused therethrough into the N-type layer 14 to create high-resistivity P-regions extending through the layer 14 to the substrate 12. Thus isolating junctions are formed between each of the regions 30, 32. In a modification, Figs. 7-9 (not shown), pockets are etched directly into the highresistivity P-type substrate and the first layer epitaxially deposited within each pocket is of high resistivity N-type material. Thereafter a further thin layer of low resistivity (N+) material is deposited and the pockets then filled with N-type material in which the components are formed. Shallow P+ annular regions may be made surrounding each component to prevent possible coupling between the components by surface N-type channels produced beneath the masking layer. The etching and epitaxial deposition processes may be carried out in the same apparatus, Fig. 10 (not shown). Etching is effected by means of gaseous HCl in a H 2  carrier and deposition by decomposition of SiH 4 , PH 3  and B 2 H 6  may be added for N- and P-type doping respectively.

In a bag filling machine, the empty bag 8 is inserted via a slot 30 in a support 26 and held by an electromagnetically controlled clamp 9 on to the end of a filling nozzle 6. The bag is inflated by a blast of air from a pipe 7, and then filled to a level 28 from the nozzle 6. At this stage the roller 15 on the rotary arm 23 pivoted at 24 is swung up to support the bag during the remaining filling time. The pivot 24 is at the base of a load carrier 13 fastened to one end of a balance beam 11, having a weight 12 at the other. The end 22 of the arm 23 is attached to the push-rod of a compressed air cylinder 14, which controls the motion of the roller 15, supplied through pipes 17 and 18, with valves 19 and 20 respectively, and exhausted through outlets 21. During filling the bag is shaken to compress the contents by actuating the roller 15 from the cylinder 14, and when filling is complete this roller is swung away as clamp 9 is released to allow the bag to slide down the support 26 on to a conveyer 27. The sequence of operations is initiated by an operator pressing a switch and subsequent actions are controlled from mechanism attached to the balance beam, or by time switches.

Abstract: 1,125,627. Delivering measured quantities of liquid; sampling liquids. N. FOSS ELECTRIC, A.S. 7 Oct., 1965 [8 Oct., 1964], No. 42643/65. Heading B8N. An apparatus for withdrawing a sample from a flow of a mixture of milk and air flowing through a main conduit 7, comprises a branch pipe 8 communicating with a sample receiving chamber 9 and a separating device 2, 6, 13 arranged to separate the flow through the main conduit into successive quantities of milk and air. The separating device includes a chamber 2 into which leads a pipe 1 for connection to a milking machine. A second pipe 14 is connected to the main conduit 7. In operation, when a vacuum is applied to a pipe 4, the air-milk mixture coming through the pipe 1 is separated so that the milk collects at the bottom of the chamber 2 while the air is drawn off through the conduit 7 and pipe 4. As the level of the milk rises in the chamber 2 a float 13 closes an inlet 6 to the conduit 7 so that only milk is sucked via the pipe 14 through the outlet 10 of the conduit 7 and the pipe 4. Due to a pressure drop at the outlet 10 determined by the setting of a needle valve 11, a constant fraction of the milk is fed through the branch-pipe 8 into the chamber. In a modification, Fig. 2 (not shown), the pipe 14 is in line with the conduit 7 and connected therewith by means of coupling 24.

Abstract: 1487098 Fastener driving tool J E SMITH and J D CUNNINGHAM 2 Oct 1974 [4 Oct 1973] 42685/74 Heading B4C A tool for applying impact forces to an object 62 comprises a ram 12 mounted for movement along a drive path toward and away from object 12, a flywheel 16 located on one side of the ram, actuating means 32 for bringing the flywheel and ram into driving engagement and a rotary means 14 located on the opposite side of the ram to the flywheel to support the ram. Preferably object 62 is a nail, staple or rivet to be driven into a workpiece. Alternatively the ram may strike the workpiece. Preferably rotary means 14 is a second flywheel journalled in fixed bearings whilst flywheel 16 and its electric motor 44M are joumalled in a movable bearing 34 comprising arms 86 pivoted about pin 88, an embodiment in which both flywheels are moved into contact with ram 12 being specified without exemplification. The actuating means 32 comprises a pair of rearwardly extending parallel arms 104 attached to a nosepiece 26. On pressing the tool against a workpiece whilst pressing trigger 54 nosepiece 26 and arms 104 move rearwards against the bias of springs 36. Ears 112 of pivoted arms 86 are received in notches 114 in arms 104. Hence rearward movement of arms 104 swings the flywheel 16 so that ram 12 is driven forwards by the two flywheels. The ram is guided in grooves 100 in arms 104, the grooves being wider than the ram to allow it to be pressed against fixed flywheel 14. The length of the ram is such that it is no longer in contact with the flywheels when it strikes resilient cushion 24 after having driven nail 62. When the tool is removed from the workpiece springs 36 pull arms 104 forwards to move flywheel 16 away from flywheel 14 and allow spring 30 to pull ram 12 back ready to drive another nail. Stop 108 limits forward movement of arms 104. On pulling trigger 54 switch 130 energizes electric motors 44F, 44M and link 140 raises stop 138 so that its forwardly projecting abutment 142 is no longer aligned with lower arm 104. Hence arms 104 can be moved rearwardly to actuate ram 12 provided trigger 54 is pulled whilst the tool is pressed against the workpiece. The speed of the electric motors is adjusted by switch 20 to control the driving power of the ram. Magazine.-Nails 62 linked by paper tapes 156 to form a belt are urged by spring driven follower 152 so that the leading nail contacts stop 158 in position to be driven by nose 122 of ram 12.
