Title: A neck binder for pigs or other animals
Inventor: DAHL CHRISTIAN THOMSEN
IPC: A01K1/064
Filed: 1981-11-19
Abstract: An animal neck binder consists of two side rods (4, 6), which are topwise releasably interconnected by means of a neck lock (8) and bottomwise interconnected by a chain (10), which is also connected to a fixed anchoring point. The side bars are topwise provided with flat connector portions (12) which from below are insertable in open cross slots (34) at both ends of the neck lock (8). The neck lock (8) is provided with spring loaded snap lock pawls (32), which are engageable with round holes (14) in the connector portions (12) of the side rods above the cross slot (34), such that the side bars (4, 6) are individually pivotable relative the neck lock (8) about a longitudinal axis thereof. The binder hereby offers a large Freedom of movement to the animal, because the side rods are not bound to be located in a common plane, i.e. they may follow the twistings as made initially by the animal for at tempting to liberate itself from the binder, and at the same time the binder is secured against distortion by these twistings. The binder is produced entirely by bending up of prepunched sheet members of stainless steel, whereby the binder is easy and cheap to produce as well as maintenance free, just as this material has proved to be well suited for contact against the neck skin of the animal.

Title: Surface box lid assembly
Inventor: FRAZER ROBERT WILLIAM
IPC: E03B9/10
Filed: 1982-07-15
Abstract: A lid assembly, suitable for fitting as a replacement for a damaged hinged lid of a surface box, locks to the surface box body by means of a locking member 12 which engages under an internal abutment of the body, e.g. the internal flange on which the lid 1 seats. The locking member 12, made of plastics, has a flexible oval hub 13 from which detainer elements 14 project for engagement under the abutment. A cam member 15 having a complementary part engaging in the hub 13 can be revolved, by a key inserted through a key hole in the lid, between positions in which the complementary part is respectively aligned with and out of alignment with the hub. In the aligned position the detainer elements 14 can engage under the abutment. In the non-aligned position the resultant distortion of the hub draws the detainer elements towards the revolving axis of the cam member to inoperative positions which allow the lid assembly to be fitted to and removed from the body. <IMAGE>

Title: Burner
Inventor: WRAY GEORGE
IPC: F23C3/00
Filed: 1983-03-11
Abstract: The present invention relates to a burner which, in one mode can serve as a burner per se and in an alternate mode as a flue for removing waste gas from a combustion space.The burner has a body 1 which defines a passage 2forming in part a flow path for gases between two openings 3 and 4. The first opening serves either as inlet for receiving air for combustion with the fuel in a combustion chamber 16 in one mode of operation or as an outlet for discharging waste gas from the passage 2 in an alternate mode. The second opening 3 serves as an outlet for combustion products in the one mode of operation or as an inlet for receiving waste gas in the alternate mode. An assembly 5 injects fuel and air into the passage 2 and the fuel and air first mix in a nozzle 31 with the fuel being ignited by an electrode 47. The fuel is combusted in a pre-combustion chamber 32 before entering the main combustion chamber 16. The fuel is partially or fully pre-combusted irrespective of the mode in which the burner is operating to avoid prepurging with air or re-ignition between flue and firing cycles.

Title: High silica/alumina ratio faujasite type NaY
Inventor: EDWARDS GRANT CAMPBELL
IPC: C10G11/00
Filed: 1983-12-14
Abstract: A sodium Y type faujasite having a high silica/alumina ratio is obtained by lowering the active soda content below the conventionally employed levels. This is done by adding an acid and/or an aluminium salt solution to the sodium silicate in the zeolite synthesis slurry. Alternatively, the desired alumina and silica starting materials can be supplied in part by using an aluminium salt gelled mother liquor. This permits the use of less reactants which are high in soda such as sodium silicate and sodium aluminate which in turn reduces the amount of soda present. This produces a NaY having a silica/alumina ratio of 5.0 or greater. These Y zeolites have a high degree of crystallinity and an absence of occluded silica. The final product can be ion exchanged to a low level of Na2O with rare earth or other metal cations or ammonium ions, to make a more thermally and steam stable zeolitic promoter for catalysts for treating petroleum fractions than can be made from conventional sodium Y.

Abstract: The friction device e.g. a brake for an elevator, includes an input means (10), an output means (80), and a mechanism (50) for transmitting torque from the input means to the output means. The torque transmitting mechanism includes a friction ring member (52) interposed between the input means and the output means, biasing members (120) urging the friction ring member into engagement with the input means, and selectively operable biasing means, such as an electromagnetic device (90), for selectively biasing said friction means away from engagement with the input means. The torque transmitting mechanism further includes an adjustable abutment device (70) interposed between the friction ring and the input means to limit motion of the friction means towards the input means and thereby limit the torque frictionally absorbed therebetween. The adjustable abutment device is automatically operable to adjust the position of the friction ring when the selectively operable biasing means is inoperative and the input means is rotating in a predetermined angular direction. The adjustable abutment device includes a first adjustment member (126) threadably interconnected with the friction ring, a second adjustment member (124) interposed between the first adjustment member and the input means, at least one ball (136) interposed the adjustment members and residing in partial raceways (Figure 5) in the adjustment members, a ramp in at least one of the raceways, and biasing elements (150) biasing the adjustment members together. <IMAGE>
