Title: Support leg for mobile cranes
IPC: B60S9/12
Filed: 1974-01-29
Abstract: 1424651 Vehicle supports HIAB-FOCO AB 29 Jan 1974 [8 Feb 1973] 04026/74 Heading B7J A leg support for mobile cranes comprises an outer leg section 4 and an inner leg section 5 telelescopically displaceable by an hydraulic piston and cylinder unit 7, 8, the leg section 5 having a foot piece 6, the section 4 in use being swingable in a vertical plane outwardly of a crane, together with the unit 7, 8 about a horizontal pivot shaft 3 mountable or the crane body 1 via a bracket 2, the swinging movement being caused by reaction when an abutment 22 on the section 5 co-operates with an abutment 28 on the bracket 2, the support leg 4, 5 being lockable in a vertical position or in the oblique outward position. The invention is characterized in that the support leg 4, 5 is also connected to the bracket 2 by two stay portions 10, 11 interconnected by a knee joint 9, the portion 11 being hinged to the leg section 4 by a bolt 13 whilst the stay portion 10 is hinged to the bracket 2 by a bolt 12. The leg section 4 is slotted at its upper end to receive a catch bar 15 vertical slidable in the bracket 2 against the action of a spring 26. Pivoted to the catch bar by a bolt 16<SP>1</SP> is a follower means 16 under the urge of a spring 17, the end surface 18 of the follower 16 being engageable with a boss 20 on stay portion 10. The leg section 4 is provided with a locking loop 25 and is urged towards the bracket 2 by a spring 27. The loop 25 is engageable with a locking boss 24 on the catch bar 15 as a bevel 23 of the catch bar 15 passes over the loop 25 when the support leg is moved to the vertical position. When the leg 4, 5, is in its vertical parked position, Fig. 2, the section 5 if desired can be lowered to engage the ground 29. To swing the leg 4, 5 outwardly, however, the section 5 is pulled inwardly of the section 4 by the unit 7, 8 so that the abutment 22 engages a fiange 21 on the catch bar 15 to lift the latter and move the locking boss 24 out of the loop 25 and disengage the support leg from the bracket 2. Further upward movement of the section 5 causes the fiange 21 to abut the abutment 28 of the bracket 2 whereafter the leg is swung outwardly due to reaction force to the position shown in Fig. 1, the knee 9 then passing downwardly over a line 14 joining the pivot bolts 12, 13 and the follower 16 abutting the boss 20 since the catch bar is urged downwards by the spring 26. The section 5 is then extended by the unit 7, 8. The leg 4, 5 is returned under the urge of the spring 27 to the vertical position by retracting the section 5 so that the abutment 22 contacts the flange 21 and lifts the catch bar and rotates, via the follower 16 and boss 20 on the stay portion 10.

Title: Immunological reagent for gonadotropins
Inventor: FULTHORPE ARTHUR JAMES
IPC: G01N33/76
Filed: 1962-02-05
Abstract: A reagent for use in determining human chorionic gonadotropin (HCG) comprises HCG-sensitized mammalian red blood cells and a borate buffer.  The reagent is intended for use in pregnancy testing by an immunological reaction in which the presence of HCG inhibits agglutination of a suspension of said HGG-sensitized red blood cells by an HCG-antibody: the borate avoids calcium interference under alkaline conditions.  The blood cells may be derived from sheep, or horse, rabbit or man and may be sensitized by means of an aldehyde (formaldehyde, acetaldehyde, pyruvic aldehyde) and a bonding agent (tannic acid, bisdiazobenzidine, 1, 3-difluoro-4: 6-dinitrobenzene, hydroquinone) and with HCG.  The reagent may contain a freeze-drying excipient (sucrose) and be freeze-dried; the HCG-antibody may also be present in the reagent in equivalent amount.  A borate buffer may also be used to reconstitute the freeze dried reagent and to dilute the urine to be tested.  The buffer may be prepared by mixing an alkali metal borate and an acid e.g. boric citric or succinic acid, if desired with sodium chloride.  Buffer tablets comprising lactose may form part of a pregnancy testing kit comprising in addition either (a) freeze-dried HCG-sensitized cells and a freezedrying encipient and (b) a freeze-dried HCG-antibody preparation or freeze-dried HCG-sensitized cells, an equivalent amount of HCG-antibody and a freeze-drying encipient.  In an example an ethylene diamine tetraacetate buffer was employed in addition in the preparation of the HCG-sensitized cells, and the 1 : 3-difluoro-4 : 6-dinitrobenzene bonding agent was used in dioxane solution.  The antibody was that produced in rabbit serum by challenging rabbits with HCG.  In a second example a phosphate buffer was employed in the sensitization stage.

Abstract: 806,750. Centrifugal pumps. LUCAS (INDUSTRIES) Ltd., J. Feb. 19, 1957 [Feb. 20, 1956], No. 5133/56. Class 110 (1). [Also in Group XVIII] A device for detecting low-level conditions in a tank c which may be a fuel tank on an aircraft comprises a shallow pressure chamber a having an inlet and outlet for connection to a pipe system b through which a liquid stream is continuously circulated by a pump, which may be the fuel feed pump of the aircraft. One side of the chamber is formed by a flexible diaphragm d which actuates a valve e serving to close the entrance of a pipe f when this becomes uncovered due, for example, to the surging of fuel in the tank, to prevent air being sucked into a centrifugal boost pump g supplying the fuel feed pump. Movement of the diaphragm may also actuate a low level alarm signal or set in motion a pump for refilling the tank. The operating pressure under the diaphragm is determined by a pressure-modifier serially connected in the liquid stream with the chamber a and comprising a body h having a passage i therethrough open to the liquid in which the modifier and the chamber a are immersed. So long as the parts a, h remain wholly immersed the kinetic energy of the stream flowing across the gap i is absorbed as it encounters the liquid in the gap so that the pressure in chamber a is insufficient to lift the diaphragm d. If the level drops below the part h the energy of the stream entering the chamber a is sufficient to exert the pressure on the diaphragm required to lift it to close the pipe f or to actuate the alarm signal or the level control means referred to above.
