Patent GB-2007569-A (GB)
Title: Method of Forming a Counterbore in the End of a Tube
IPC: B21C1/24
Filed: 1978-11-02
Abstract: The tube of circular or non- circular cross-section is first arranged on one side of a die (13 or 19 or 24), a mandrel (12 or 18 or 23) being disposed on the opposite side of the die, relative movement then being effected between the tube on the one hand and the die and the mandrel on the other hand to cause the end of the tube to enter said die and engage the mandrel which is larger in cross- section than the tube end so that the latter will be bulged by the mandrel, whereafter relative movement is effected between the die and the mandrel to move the die towards and over the mandrel and thereby draw the bulged end portion of the tube on to the mandrel. <IMAGE>

Title: Ultrasonic transponder
IPC: G01S7/521
Filed: 1979-02-14
Abstract: A transponder capable of transmitting and receiving ultrasonic signals for liquid level gauging, the elapsed time between the transmission of a pulse and the reception of an echo pulse reflected from the surface of the liquid being measured to afford an index of the level of the liquid. The transponder is constituted by a piezoelectric transducer assembly 15, Fig. 2 suspended within an open-ended casing 19, Fig. 3 by an electrically non-conductive elastomeric material 20 which serves to rapidly damp the vibratory activity of the transducer to prevent ringing thereof which interferes with reception. In the assembly 15, the piezoelectric transducer is sandwiched between a loading plate 16 and a horn-shaped radiating plate 17, the assembly 15 being held together by a bolt 18 which extends between the plates 16, 17 and passes through the transducer. The transducer operates in the compression mode and is therefore capable of operating reliably with a high voltage drive signal to cause the radiating plate to emit an ultrasonic beam having a narrow angle. <IMAGE>

Patent GB-2017227-A (GB)
Title: Thermally Actuated Pump
IPC: F04F1/04
Filed: 1979-05-11
Abstract: The invention relates to pumps of the type in which liquid is drawn into and discharged from a pump chamber 35 through valves 36, 37 respectively by oscillating liquid in a pipe 25 connected to the chamber 35, the liquid being caused to oscillate by alternate vaporising and condensing of the liquid. As shown, liquid volume 19 is insulated from liquid volume 18 which is in contact with heated wall 12 whereby vapour is generated above both volumes and drives liquid out to cause pump discharge. The outflow of volume 18 is restricted by throttle 29 so that the inflow and outflow is less rapid than the flow of volume 19. When volume 18 is sufficiently reduced cooled wall 14 is exposed so that condensation takes place whereby liquid volume 19 refills and liquid enters the pump volume 18 then refills and the cycle repeats. The volumes 18, 19 may occupy separate chambers and a membrane may be disposed between the actuating liquid and the liquid in the pump chamber 35. <IMAGE>

Abstract: A corner connector for a frame has two limbs which are each bifurcated, and have backwards-facing teeth 22. Each limb is of such a size that, when inserted into a correctly-sized hollow frame member, the two furcations 20 are deflected elastically, so that the teeth are pressed against the interior of the frame member, and hold the cleat in place. A nylon insert 26 is provided between the furcations, and assists the resilience of the furcations 20 in pressing the teeth 22 against the interior of the frame member. The connector consists of a slice from an extrusion of an appropriate cross-section. <IMAGE>

Patent GB-2088450-A (GB)
Title: Grouting piles
IPC: E02D5/62
Filed: 1980-11-19
Abstract: This invention relates to piling where the lower end of the pile is to be grouted to the bedrock. A hole is drilled downwardly from ground level through the over-burden into the bedrock 12. The bore in the bedrock may however be a very long way below ground level but despite this the grout bond should be of high quality. The lower end of the pile is provided with a radially inflatable closure 38 which is spaced from its lower end by an amount substantially equal to the length over which it is to be bonded to the bedrock. When the hole has been drilled and the pile lowered into it, that closure is then inflated to seal off the region bored in the bedrock and liquid grouting material is pumped into that region. Before this is done, however, it may be desirable to flush the region with water until the water leaving that region is sufficiently clean. In addition the grout may be supplied under high pressure to penetrate and seal any fissures in the bedrock. <IMAGE>
