Patent GB-2451740-A (GB)
Title: Pre-stressing or confinement of materials using shape memory polymers
Inventor: JEFFERSON ANTHONY DUNCAN
IPC: B29C61/00
Filed: 2008-08-01
Abstract: The invention discloses a method for multi-axial confinement of materials such as cementitious composites and particulate structures, using a polymer as a composite, wherein the polymer returns to its original shape upon heating. The mechanical shrinking action of the polymer will cause strain, for example compression, in the material to be confined. In one embodiment a structural element 5 formed from a cast cementitious matrix 20 has an internal lattice 10 in the form of a rigid three dimensional grid formed from intertwined rods of a polymer based reinforcement. When heated above an activation temperature the rods material memory will cause them to strain to return to their original shape. Heating may be carried out by connecting the grid to an electrical source by means of electrical supply interface 30. A later embodiment relates to a casing (45 figure 2) for an underground tunnel wall comprising a cementitious matrix (50 figure 2) containing heat shrinkable fibres (60 figure 2) with barbs (65 figure 2) at each end. The fibres are sufficiently numerous such that they overlap and interlock with each other thereby preventing slip at the polymer and matrix interface. Examples of uses include strengthening of concrete structures, repair, autogenic healing of cracks in concrete, wrapping damaged structural elements and reinforcement of particulate structures such as flood defenses and railway embankments.

Title: Improvements in and relating to grinding machines
IPC: B24B3/02
Filed: 1952-04-22
Abstract: 700,797. Grinding cutter heads. DORRENBERG, E. H. April 22, 1952 [April 27, 1951], No. 10117/52. Class 60 A cutter head 2, Fig. 1, is mounted on a mandrel 3 supported vertically between non- rotatable dead centres 4, 5 and is ground by two grinding wheels 17, 18, Fig. 2, rotated in opposite directions by independent motors and mounted on a common rotatably adjustable support 13. The latter is adjusted by a worm drive 14a and is mounted on an arm 12 rotatably connected to a vertically adjustable slide 11, the weight of this assembly being partly counter-balanced by oil pressure acting on a piston 20. An upright 10 supports the slide 11 and is mounted for transverse adjustment on guides 9 connected to a longitudinal slide 7 by a rotary slide 8. The slide 7 is connected to a fluid-operated piston 25 which moves the grinding wheels towards and away from the cutter head in timed sequence with intermittent rotation of the latter. vertical or horizontal feed motion being applied to the grinding wheels through a shaft 45 and ratchet mechanism. The intermittent or indexing motion of the cutter head is provided by a fluid-operated piston 29 which through a rack and pinion gear rotates a shaft 31, Fig. 3, connected by gears 32, 33 with a sleeve 34 concentric with the lower dead centre 4. This sleeve has a spring-loaded tappet 35 in engagement with a driving plate 36 on the mandrel 3. Each forward movement of the piston 29 rotates the cutter head beyond its correctly indexed position which is determined by a spring finger 37 being brought into contact with the appropriate tooth of the head when the latter is rotated in the reverse direction by the backward stroke of the piston. A slipping coupling, interposed between the index mechanism and the piston, enables the latter to continue its backward movement after the cutter has been engaged by the finger 37. A hydraulically-operated clamping sleeve 39 ensures that the cutter is firmly retained in each indexed position. The grinding head is oscillated to effect relative movement between the grinding wheel and the cutter head during the grinding operation by an eccentric (not shown) mounted on a shaft 52, Fig. 5, driven by toothed gearing and a belt drive from the grinding wheel motors. The number of strokes made on each advance of the slide 7 is determined by a drum 61 driven through toothed gearing from the shaft 52 and provided with a number of circumferential strips which have differently spaced series of notches to operate the plunger of a switch which through a magnet controls a distribution valve for the piston 25. A pin 63 enables the drum to be displaced axially and hence the required strip to be brought to operative position. The upper dead centre 5 is mounted on an arm 6 which can be swung clear of the machine frame and is provided with an electrically driven hoist for large and heavy cutter heads. The arm itself may also be lifted hydraulically in order that the head may be lifted above a water collecting pan 75 before it is lowered on to the dead centre 4.

Title: Variable gain electron multiplier
IPC: H01J29/02
Filed: 1945-04-24
Abstract: 598,601. Valve amplifying circuits. FARNSWORTH TELEVISION & RADIO CORPORATION. April 24, 1945, No. 10336. Convention date, Jan. 14, 1944. [Class 40 (v)] In an electron multiplier the output is limited by switching the utilisation circuit to a lower stage electrode when the output reaches a critical value, the switching means being under the control of current from a higher stage or collector electrode. In Fig. 2, the emission from photo-electric screen 12 is amplified by an eleven-stage electron multiplier in which collector 32 is normally connected to the utilisation circuit 61, 63 via the back contacts of three similar relays 48, 49, 51. The operating coils of these relays serve as load impedances respectively of secondary emitters 31, 29, 28, which may be substituted successively as collectors by operation of their associated relays. When the current to the electrode 31 reaches the operating value of relay 48, owing to increased strength of input signal, contacts 54, 56 change over to transfer the collector 32 to cathode potential and connect electrode 31 as collector for the utilisation circuit via back contacts 53, 52. Similarly, relay 49 operates when the current to electrode 29 reaches the critical value transferring electrode 31 to cathode potential and connecting electrode 29 as collector for the utilisation circuit. Relay 51 acts similarly under the influence of electrode 28 and the reverse sequence occurs for decreasing signal strength. In a modification, Fig. 3, the series connected relays 68, 69, 71 operate at successively higher anode current values from valve 72 determined by the grid potential built up across resistor 55 by current from collector 32. The secondary emitters 31, 29, 28 are not used as collectors and the phase inverting stage 72 is required for coupling the collector electrode to the utilisation circuit 78, 63 to preserve phase continuity during switching. Current to the secondary emitters builds up potentials across load impedances 65, 66, 67 which may be connected selectively to the utilisation circuit by operation of the associated relay when the required current density is received at collector electrode 32.
