Title: Method and device for friction welding
IPC: B23K20/12
Filed: 1970-12-17
Abstract: 1329834 Welding by pressure K-H STEIGERWALD 17 Dec 1970 [18 Dec 1969] 59882/70 Heading B3R In a method of friction welding, workpieces, which may be of irregular cross-section, are friction welded by imparting motion thereto such that neither workpiece rotates about its own axis but relative orbital motion occurs to generate heat for welding the amplitude of the orbital motion varying during the welding process. In one embodiment (Figs. 1 and 2 or alternatively Fig. 3) one workpiece is held stationary and the other made to move in a circular orbit. In a second embodiment (Fig. 4, not shown) the workpieces are reciprocated harmonically in mutually perpendicualr directions, the phase relation being such as to provide a resultant relative motion which is preferably circular in locus. In the apparatus shown two eccentric bodies 2, 8 are arranged for rotation about the axis 6 and a work-holder 14 is mounted on the body 2. The workholder is restrained against rotation but is free to gyrate with and on the eccentric body 2 by means of a parallel link and slide mechanism (Fig. 2, not shown). The bodies 2. 8 are angularly adjustable relative to each other to adjust the resultant eccentricity from zero to maximum value, this adjustment being possible during drive so that the amplitude of the orbital path of the workholder 14 can be raised from zero at the commencement of the welding cycle to a maximum value and adjusted to zero again to bring the workpieces into the desired alignment for final welding. Adjustment of the eccentricity is effected by axial movement of a shaft 62 having a pin 60 which projects through angled slots 56, 58 in drive parts 46, 48 connected respectively to the eccentric bodies 2, 8. Control means 92, 94, 96 are provided for varying the speed and amplitude of the orbital motion of the work-holder; the speed and amplitude may be varied simultaneously in inverse relation so as to maintain a constant relative velocity at the rubbing surfaces. Adjustably mounted counterweights 98, 100 are provided for dynamically balancing the apparatus. It is envisaged that the amplitude and frequency of the relative motion may be controlled in conjunction with an initial phase in the welding cycle in which the workpieces are reduced to a predetermined length. Alternative mechanical means (Fig. 3, not shown) are described for use instead of the eccentric members to provide adjustment of the overall eccentricity and it is envisaged that hydraulic or electrical means may also be used for this purpose.

Title: Selector mechanisms for change-speed gears
Inventor: MAINA MARIO JOSEPH
IPC: F16H59/02
Filed: 1968-12-19
Abstract: 1,218,440. Change-speed control. VAUXHALL MOTORS Ltd. 5 Nov., 1969 [19 Dec., 1968], No. 60286/68. Heading F2D. A motor-vehicle C.S.G. (not shown) providing three or, as shown, four forward speeds and one reverse and an auxiliary C.S.G. (not shown) providing two futrher ratios, one or both of which may be overdrive ratios, are controlled by a single shift lever 1, movable in a two-range e.g. " high " and " low," shift pattern gate (Fig. 7, not shown). The gear shift lever 1 is universally mounted via a pivot 2 on a carrier 3 which in turn is pivotally mounted on pins 4 at right angles to the pivot 2, the carrier 3 being additionally slidable on the pins 4 and normally biased by a spring 5 against a easing shoulder 6. The shift lever 1 has a forked end 8 engaging a cranked arm 9 of a turn-and-slide rod 12 for selection and engagement of the four forward ratios and reverse as illustrated in the " low " shift section of the gate in Fig. 7 (not shown), an interlock plate 11 co-operating with a hooked-latch member 14 of a control lever 16 of the auxiliary two-speed C.S.G. to maintain the auxiliary gear in its low-range condition illustrated in Figs. 2 and 3. The shift lever carrier 3 co-operates with a forked notch 17 on the hooked-latch 14 such that further movement of the shift-lever 1 to the extreme end of the gate (Fig. 4) causes the shift-lever to pivot on the cranked arm 9 and slide the carrier 3 along the pins 4 against the spring 5, whereby the hooked latch is pivoted to lock around the interlock plate 11 as the auxiliary gear control lever 16 is moved to its " high " range condition, the shift lever 1 then being movable in the gate (Fig. 7) in a " high " range between the third and fourth ratios. A notch 19 in the carrier 3 co-operating with a stepped pin 7 ensures that the shift-lever 1 can only move the auxiliary gear lever 16 when the shift-lever 1 is in the central neutral channel of the gate. The forked end 8 of the shift lever 1 has uneven length legs, the longer of which forms a reverse ratio fork engaging the turn-and-slide rod 12 until manually lifted clear thereof via a spring-loaded collar 10 on the shift lever 1.
Patent GB-730308-A (GB)
IPC: G05D9/12
Abstract: 730,308. Automatic liquid level control systems. BABCOCK & WILCOX CO. Oct. 27, 1952 [Nov. 10, 1951], No. 26949/52. Class 38 (4). [Also in Group XXII] In a continuous casting machine (see Group XXII) a thermal sensitive element is embedded in the mould wall and an electric control system is operatively connected with the power driven pouring vessel and the thermal sensitive element to regulate the pouring rate in response to changes in the level of molten metal within the mould. The thermal-sensitive elements may comprise thermo-couples or resistance thermometers. The platinum resistance T, Fig. 8, is connected in a bridge network and a variable resistance R adjusted to balance the bridge when the molten metal level is in a desired position. An amplifier and motor control MC regulates the operation of a potentiometer motor M to continuously balance the circuit in accordance with changes of temperature in the resistance T due to changes in the level of molten metal in the mould. The motor M may be connected direct or through power amplifying means to an adjustable rheostat in the pouring motor circuit. In a preferred embodiment, Fig. 7, two measuring units X, Y, with control circuits as in Fig. 8, comprise shafts 51, 52, driven by the potentiometer motors and connected with a differential gear 53, the output shaft 54 of which is connected to a rheostat in the pouring motor control circuit. The units X, Y are electrically connected in parallel to resistance element T and resistance R and also with a standard resistance unit Z, switches 1C-1E being operated in timed sequence to alternately connect one measuring unit to the elements T, R while the other is connected to the standard Z. Thus in the position shown, if the molten metal level is above or below its desired position, the shaft 52 will rotate due to the connection of unit Y to the elements T, R, while the shaft 51 will rotate, due to the connection of unit X to the standard Z and the consequential return of the network to its normal balanced condition, in a sense depending upon the position of the molten metal level during the previous period of connection of the unit X to the elements T, R.

Title: Analysis for Antibiotics
IPC: G01N33/487
Filed: 1978-11-16
Abstract: A process for rapidly detecting as little as .001 I.U. of antibiotic in a sample of liquid such as milk involves incubating the sample with a tagged antibiotic, antibiotic precursor or antibiotic derivative and antibiotic- sensitive cells or cell constituents under conditions which allow antibiotic molecules to attach to receptor sites in or on the cells or cell constituents. Antibiotic in the sample and the tagged antibiotic species compete for receptor sites, the amount of tagged antibiotic becoming attached to said sites being dependent on the amount of antibiotic in the sample. Following incubation the cells or cell constituents with immobilized antibiotic are separated from the remainder of the reaction mixture and the presence, and if desired the amount, of tagged antibiotic on the cells or cell constituents is detected by reference to previously prepared known standards.

Title: Camera
IPC: G03B7/16
Filed: 1979-03-23
Abstract: A camera has means for preventing charging of a flash capacitor (36) during operation of an automatic focussing device. The automatic focusing device employs a sonic range finder and the flash apparatus comprises a flash tube (40), a capacitor (36), and a D.C. - A.C. - D.C. power converter (38) for charging the capacitor from a battery (34) through a switch (32). A charge regulator comprises a comparator (42) and a switching circuit (46). A disabling circuit (44) prevents the power converter from charging the capacitor when, following actuation of a push-button (29) a switch (S2) indicates that the lens has been moved from and has not returned to a predetermined position, thereby preventing spurious radiation from the converter from affecting the operation of the sonic range finder and also preventing the charging load being imposed on the battery while the automatic focusing takes place. When the capacitor (36) is charged, an enabling circuit (48) permits a trigger circuit (50) to respond to a flash fire signal from the camera. A preview timer (Fig. 4 not shown) may be provided to permit an operator to see and compose the picture after focusing and before he initiates the exposure operation. <IMAGE>

Title: Method of and apparatus for testing metal walls, such as ferrous pipes
IPC: G01N27/90
Filed: 1979-05-02
Abstract: In non-destructive testing of metal walls, more especially a ferrous pipe's external walls, a ferrite-cored coil L1 inserted into the pipe is fed (TR2) with current pulses and then short-circuited (SW1) (the duration of the short differing on alternate cycles), after which its output is detected by a peak detector (IC4, D2, C8) and alternate peaks passed to separate storage buffers. (IC9, IC10). The peaks (PA) derived from the coil after shorting for a shorter period are attenuated (P3) and differentially amplified (IC11) with the peaks (PB) obtained after shorting for a longer period. The peaks PA contain only data on the position of the probe relative to the pipe's internal surface. Peaks PB also contain these data as well as data concerning flaws in the bulk of the metal and on the exterior of the pipe. By differential amplification of peaks PA & B, the data concerning flaws may be obtained, the signal concerning probe position, which is common to both peaks, being eliminated. <IMAGE>
