Patent GB-764486-A (GB)
IPC: H01L29/88
Abstract: 764,486. Extruding concrete pipes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 20, 1955 [Jan. 20, 1954], No. 1762/54. Class 87(2). [Also in Groups X, XXVIII and XXIX] A pump for wet concrete &c. in the plastic state comprises a tube 11 having an inlet 14 at one end and the other end open to serve as an outlet to a receiver such as a hose 20, means such as a double acting ram 25 to reciprocate the tube 11 slowly on the working stroke by hydraulic fluid from a reservoir 32 kept under pressure by a pump 33 and rapidly on the return stroke by compressed air from a cylinder 37 when a poppet valve 36 on the liquid side of the ram piston 27 has been opened. Concrete mix is stored in a hopper 13 open at its lower part to the tube 11 and provided with a torque 21 fitting the tube and preventing reverse movement of the concrete. As the piston 27 moves the tube 11 forwards an arm 55 on its piston rod 28 moves a connecting rod 43 forwards so that an arm 50 thereon compresses a spring 51 surrounding a rod 44 until the spring is sufficiently compressed to free the rod from a detent 45 and move it to a second detent position 46 whereupon it strikes the stem 41 of the valve 36 opening the valve and permitting the compressed air to return the piston and tube so rapidly that the tube is jerked away from its concrete content leaving it behind. The effect may be accentuated by widening the bore of the tube 11 at its outer end. Flow of the concrete may be facilitated by introducing water through a pipe 61 ahead of the tube 11 and withdrawing it further along as the mass passes through a perforated portion of the hose 20 surrounded by a vacuum chamber 64. To adapt the device for an extrusion operation, a central core may be introduced into the tube 11 and may be reciprocated therewith.

Title: Reducing the effect of noise on impedance measurements
IPC: G01R27/02
Filed: 1978-08-04
Abstract: In order to reduce the effect of mains frequency noise induced into a line whose impedance is under test, the test voltage applied to the line is chosen to have a frequency which is either a sub-multiple of half the mains frequency or an odd multiple of half the mains frequency, and the resulting line current is integrated over a period equal to a whole number of complete cycles of the mains frequency, whereby the induced noise should average to zero. In the preferred embodiment, a two-wired long telephone cable is tested using a test voltage of half mains frequency and a measure of the integrated value of the line current is made for a period equal to one-half cycle of the applied test voltage with one polarity and one-half cycle with the polarity of the measured signal representing line current reversed. The integration periods are selected to be in phase with the applied signal for determining conductance and 90 DEG  out of phase for determining susceptance. <IMAGE>

Title: Supporting stator end windings of electric machine
IPC: H02K3/50
Filed: 1978-11-03
Abstract: An arrangement for supporting stator end windings of an electric machine comprises a rigid inner ring 8 and an outer ring 12, both rings being made of electrically insulating material. The inner ring 8 is mounted coaxially with the inner bore of the stator core 1 and supports the end portions of a stator bar winding, and the outer ring 12 externally embraces these end portions. Both rings are mounted and secured together along the head portions 5 of end windings, the inner ring 8 being attached to Z-shaped members 15 arranged adjacent to the end portions and preventing the inner ring from axial displacements relative to the end portions. This is achieved due to the fact that the projection 18 of each Z-shaped member, facing the end surface of the core 1, is positioned between winding bars at their outlet from core slots 2, and is rigidly connected with a bracket 20 movably associated with a clamping plate 6 of the core 1 and attached to the outer ring 12. Thus, the arrangement for supporting the end windings and the end windings themselves makes up a rigid integral unit resistive to the action of vibrations arising during operation of the electric machine and axially displacable under thermal expansion of the winding bars. <IMAGE>

Patent GB-2023816-A (GB)
Title: Improvements in or relating to bioassay
IPC: G01N33/74
Filed: 1979-06-19
Abstract: A process is disclosed for determining the concentration of an unbound species, e.g., thyroxine, cortisol, testosterone, or digoxin, in a liquid sample containing the species and protein. The sample is incubated with antibody specific to the species to be detected and a distinguishable analogue of the species, the antibody being initially separated from the sample by semipermeable membrane capable of excluding the passage of natural protein and antibody but allowing passage of the species and its analogue. The antibody and analogue are contained in semipermeable microcapsules. Free species in the sample permeates the membranes and competes for sites of attachment to the antibody with the analogue. The antibody is then separated from residual unbound species and unbound analogue. The amount of analogue present either in association with the antibody or in the remainder of the reaction system is indicative of the level of unbound species originally present in the sample.
