Title: Improvements in the withdrawal of samples of gases and in the sampling of gases
IPC: G01N1/22
Filed: 1967-05-01
Abstract: 1,122, 885. Sampling gases for analysis. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. May 1, 1967 [May 16, 1966], No. 19954/67. Heading G1B. A device for withdrawing gas samples from a gas flow in a conduit, e.g. in a blast furnace, comprises a cylindrical tube 16 exterior to the conduit on which is mounted by way of a sleeve 19 a steel tube 20 projecting into the conduit and carrying a tip 22, a porous tube 23 being clamped between the sleeve 19 and tip 22 and the tube 20 being apertured along its length, so that when a suction pump is coupled to a connection 15 a gas sample representative of the gases flowing in the conduit will be obtained. To this end the porous tube 23 is arranged to project to at least the centre line of the conduit and thus the sample obtained will be representative of the whole gas flow and not just the gases flowing near the walls of the conduit. A semi-circular section shield (not shown) is provided along the length of the tube 23 to protect the upstream side of the tube from the effects of fine dust in the gas stream striking the porous tube and blocking it up. An electrical heater 25 is provided inside the tube 20 to prevent moisture condensing in the porous tube 23. The porous tube itself may be of porous bronze, ceramics or asbestos. The device is arranged so that it may be slid into position in the conduit through a suitable closable valve, and where the device is used in a vertical conduit it is arranged to project upwardly at an oblique angle therein to prevent solid materials collecting on the device.

Title: Magnetic recording head structure
IPC: G11B5/187
Filed: 1961-06-02
Abstract: 907,955. Magnetic recording &c. heads. SYLVANIA ELECTRIC PRODUCTS Inc. June 2, 1961 [June 24, 1960], No. 20035/61. Class 40 (2). [Also in Group XXII] A magnetic recording head is made by evaporating a layer of magnetic material on to a support and by then cutting an air gap. The support, preferably of glass tubing, is first masked into bands, where a stacked head is to be made, and a preliminary, tenacious coating of about 1 Á thickness of an iron-rich nickel/iron alloy deposited, followed by a layer of 10 to 25 Áthickness of a nickel-rich alloy. The region which will be away from the gap may also carry an additional thickness of alloy. The gaps are produced in line across all the component heads by a diamond cutter. It is found that the gap spacing is related to the deposited thickness so that gaps narrower than the thickness of the deposit may be produced by controlled electrolytic build-up. As an alternative, the gaps may be etched. Compared with conventional heads, the thin poles have low leakage inductance and low fringe fields. In Fig. 3, the support is in two parts; the bands 32 are continued diametrally inwardly on the curved member 30, which is clamped to a striped flat member 48, gapped at 56 to provide space for windings and inter-winding screens (not shown). In Fig. 4, a circular glass tube is provided with winding apertures 78 opposite the gaps 24.

[Also in Group XXIII] Means for eliminating the effects of temperature-variation on the position of the tool in a drilling &c. machine, comprises an expansion-bar 12 linking the tool-support 9 to the machine-frame 1, the end 13 of the bar towards the tool-spindle being fixed to the frame 1 and the other end 14 to the support 9. An expansion-bar 12 may be provided at both sides of the support 9, Fig. 1. The bars 12, being shorter in length than the support 9, are of a material having a higher coefficient of thermalexpansion than that of the material of the support 9 and frame 1, so that the position of the tool relatively to the work 4 on a compoundtable 2 remains unchanged by thermal expansion of the support and of the frame. The tool may be carried in a head 11 angularly adjustable on the support 9. In a modification, Fig. 3, a single expansion-bar 20 is used, being keyed at one end 21 to the frame 1 and at the other 23 to the support 9. A driving-gear 32 for the tool-spindle may rotate on the bar between a pair of guide-bars 25, Fig. 4, mounted on the support 9 and engaged in passages 26 in the frame. A third guide-bar may be provided, and the top 24 of the support may be dove-tailed into the lower part to facilitate the use of different tools. Instead of the support being mounted in guide surfaces on the frame 1, it may be supported out of contact with the frame on broad leaf-springs 112, Fig. 7, attached at one end to the support and at the other to the frame. In modifications of this embodiment, Figs. 9-11 (not shown), the exposed length of the leaf-springs may be reduced and they may be formed with enlarged ends to facilitate attachment.

Title: Fully automatic control system for apparatus for thermally treating metal bodies
IPC: B23K7/06
Filed: 1946-07-12
Abstract: 614,575. Dividing by fusion. LINDE AIR PRODUCTS CO. July 12, 1946, No. 20988. Convention date, Aug. 28, 1945. [Class 83 (iv)] [Also in Group II] In an automatic control system for apparatus for thermally treating, e.g. de-surfacing, metal bodies, a detector operates means to slow down the body on approaching the apparatus, means responsive to the continued slow advance stops the body at the treating position, and timing means controls the treatment, advances the body and resets the system on completion. In de-surfacing apparatus the detector comprises a spiked wheel 12 and a selsyn transmitter 21 keyed to a shaft 13 mounted in a pair of counterweighted arms 15 pivoted on a shaft 18 carrying a switch-operating arm 19. When a body 10 carried on rollers 11 depresses and rotates the wheel 12, the arm 19 closes a switch 23 to energize the selsyn circuit I, causing pinion 37 of selsyn receiver 27 to raise a weighted rack 36 in synchronism with the wheel 12. On completion of a preset number of revolutions of wheel 12, the rack 36 closes a lower switch 38 and feeds A.C. to a relay R1 controlling a D.C. supply through a contact 43 to slow down the roller motor R. Following a further preset number of revolutions of wheel 12 at reduced speed, the rack 36 closes an upper switch 49 and operates a multiplecontact relay R2 which is self-locking through its own contact 53 and a switch 56 in a sequence timer T2. Relay R2 opens a D.C. circuit through contact 60 to stop the roller motor R and the body 10 in position for de-surfacing to start; opens contact 29 to de-energize selsyn circuit I and allow rack 36 to fall, and through contact 64 sets the timer motor 70 of a sequence-timer T1 in operation. A group of contacts 79 are thus closed to register the desurfacing nozzles H with the body 10, and turn on pre-heating gas, slag-removing water, and de-surfacing oxygen in timed sequence. After an interval to allow the process to start, timer motor 70 closes a further contact 72 and supplies D.C. to restart the motor R and advance the body at de-surfacing speed. The wheel 12 rises when the tail of the body passes clear and arm 19 closes switch 80 setting timer motor 87 of timer T2 in operation. The body 10 is stopped just as its tail reaches the nozzles H when the timer motor 87 stops the roller motor R and retracts the nozzles H after the gases and water have been turned off by opening a group of switches 90. Switch 56 in timer T2 finally opens and the system is reset. In a modification the wheel 12 contacts the side or top of the body 10 and the pinion 37 is driven direct through flexible-shafting from the wheel 12, a clutch controlled by the circuit I being incorporated.
