Title: Wall Plug Assembly.
Inventor: FISCHER ARTUR
IPC: E04B1/38
Filed: 1968-11-12
Abstract: 1,187,909. Wall plug assembly. A. FISCHER. 12 Nov., 1968 [13 Nov., 1967], No. 53490/68. Heading F2H. In a wall plug an expanding element 7 is drawn into an expansible sleeve 5 by the fastening element 1 which has a part 3 of its shank of the same diameter as the external diameter of the sleeve and a part 4 of lesser diameter for passing through the sleeve and engaging the expander. The two parts of the shank have substantially the same tensile strength the part 4 being either treated, e.g. heat treated to increase its strength if integral with the part 5 or being of a different stronger material to part 5. In order that the fastening element may be pulled into a hole after expansion of the sleeve there may be provided means between the sleeve and the part 3 of the shank which collapses axially at forces greater than that required to expand the sleeve. This means may be separate, or integral with the sleeve, e.g. an extension of the sleeve or axial projections on the sleeve, and is preferably an annular member 9 (Figs. 2 and 3, not shown) which deforms plastically or elastically. As shown in Fig. 3, the annular member has a lug 10 for engagement with a corresponding recess 11 in the sleeve and may have radial projections 12 for engagement with the bore walls. The annular member also serves, upon initial deformation to engage the bore walls when fastening is commenced, to lock the sleeve against rotation and hence to prevent rotation of the expander if this is prevented from rotating relative to the sleeve. The sleeve is provided with longitudinal slots and is either conically flared or carries internal ribs for engaging the expander. Two expanders may be used. The shank 3 of the fastening element may be threaded adjacent the head.

Title: Gauging of heat flux
IPC: G01K17/00
Filed: 1972-11-27
Abstract: 1423830 Measuring heat flux BABCOCK & WILCOX Ltd 27 Feb 1974 [27 Nov 1972]  54745/72 Heading G1D Heat flux impinging on a region of a combustion chamber is gauged by temporarily positioning a probe 6 at the region of the chamber so that a surface 8 of heat-conductive material forming the probe becomes exposed to the heat flux and obtaining a measure of the rate of heating up of the probe 6 when so positioned. The probe 6 may comprise a cylindrical slug of copper having a thermocouple located therein and surrounded by a mica layer 11 and a stainless steel tube 12. The tube 12 having vents 24 houses a tube 22 for supplying compressed air to a nozzle 21 which is directed towards the probe 6 for cooling purposes, the tube 12 being surrounded by a plurality of radially spaced tubes Fig. 2 (not shown) having vent holes (41), and connected by way of a tube 14 and a coupling to control apparatus, Fig.5. The control apparatus comprises an electric circuit provided with relays (I and II), "start" and "cancel" switches (51, 52), switches operated by the relays, switches operated at predetermined temperatures sensed by the probe 6, a magnetic clutch W for a timer Y, a device U for activating the compressed air and warning lamps (53, 54, 55). With the probe 6 below a predetermined base temperature at which switch (LL) is closed, the start switch (51)  is temporarily closed so that relay (I) becomes  energized and, as a consequence of switch (I/I) closing, remains energized. Relay (II) becomes energized when the start switch (51) is released. The probe 6 is now inserted into the chamber. Upon rising to a predetermined first temperature, switch (L) completes the timer circuit until switch (H) closes to 104 at a second, higher, temperature. The timer then stops, relay (I) becomes de-energized to close (1/2) and the device (U) is activated to supply compressed air to the nozzle 21 to cool the probe 6. The probe 6 is removed from the chamber and cooling is effected until the probe 6 is at a temperature below the base temperature. The timer Y may be read before the switch 51 is depressed again. Upon depressing the switch 51, switch S/1 is opened to de-energize relay 11 and the magnetic clutch W so that the timer pointer, drivable by the clutch W,.can return to zero. The device U also becomes de-energized.

Abstract: 1431226 Testing integrated circuits and similar components INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1973 [26 Dec 1972] 55402/73 Heading G1U An arrangement for testing an integrated circuit 10, Fig. 1, or other component having a plurality of pads 11, with which electrical contact must be made to effect the test, is characterized in that the device under test can be placed in an arbitrary position on an array of probes 14, see also Fig. 2, and in that once the device is in position the probes are sequentially examined under computer 22 control to establish which pairs of probes are electrically shorted and hence to establish the position of the device under test on the array of probes. Once the position of the device is established any appropriate test can be performed. Clearly, for the arrangement to operate properly (a) the probes must be sufficiently close together so that in general each contact pad 11 on the device will be touched by two probes 14, Fig. 2, and (b) the probes must be sufficiently small in diameter not to bridge the gap between any two contact pads. In general the computer would be programmed in advance with the relative positions of the contact pads of the device under test so that it would not be necessary to locate every contact pad. In fact, even with closely spaced probes it may still be possible for some contact pads each to touch only one probe (rather than two), but providing sufficient pads each touch two probes the computer will be able to determine the position of the device.

Abstract: 1426280 Impulse generators INTERNATIONAL STANDARD ELECTRIC CORP 6 Dec 1973 [11 Jan 1973 15 Feb 1973] 56520/73 Heading H4K Lost motion is provided in a telephone dial mechanism by rotating a member with the impulsing cam, which member engages a number of stops in turn and stops rotating on engaging each stop until it is released therefrom due to a lateral movement caused by the eccentricity of the cam. The member eventually rotates to engage a spring set when rotation of the cam causes the impulsing contacts to be operated. Similar arrangements are disclosed in Specifications 1,239,038 and 1,426,279 which are referred to. First embodiment (Figs. 1 and 2).-During setting cam B is driven anticlockwise and the lost motion member rotates with the cam until projection C engages contact operating arm E. On release cam B and the member rotate clockwise until projection H or arm C engages a stop G and the member stops rotating. Continued rotation of the cam causes a lateral outward movement of the projection H to release the member which recommences to rotate. A similar operation occurs when projection H engages a further stop F except that an inward lateral motion causes the release. Eventually an arm D of the member engages the contact springs A and the member stops rotating. Continued rotation of the cam then causes a lateral up and down movement of the arm D to operate the impulsing contacts substantially as described in Specification 1,239,038. In a second embodiment (Figs. 4 and 5) the arms C and D are combined into a single arm 2 having a projection 4. A stop 5 may be provided for determining the starting position of the member and a further stop may be placed adjacent the impulsing contacts to prevent the arm riding up on the top one of the two impulsing contacts. To increase the lost motion period the number of rotational stops such as F and G may be increased to three.
