Filed: 1974-04-10
Abstract: 1468872 Power steering mechanism DANFOSS AS 10 April 1974 [14 April 1973] 15910/74 Heading B7H [Also in Divisions F2 and G3] A valve for connecting both the supply and return lines (6, 7) of a double acting cylinder (8) of a steering system to drain to relieve excess pressure or top-up such lines has a main valve member 27 which co-operates with a seat 30 between chamber 35 connected to one of the lines and chamber 36 connected to drain. If the pressure in chamber 35 rises above a predetermined value the pressure in chamber 39 which is connected to chamber 35 via restriction 40 rises to a similar value to unseat a pilot valve member 41 to relieve the pressure in chamber 39 and allow the pressure in chamber 35 acting on valve member surface 31 to unseat the valve member 27 to relieve the pressure in chamber 35. When a reduced pressure occurs in chamber 35 this pressure is communicated to chamber 39 and also to chamber 49 via restrictor 50, the non-return valve 51 closing; the pressure in chamber 36 acting on valve member surface 32 then unseats the valve member 27 to top-up the pressure in chamber 35. Restrictors 40, 50 can be replaced by leakage between valve member 27 and sleeve 22. The other line connected to the cylinder (8) connects with port 20 and is connected to chamber 36 by a similar valve construction. The two lines (6, 7) are connected to a pump (1) or drain (5) by a steering wheel operated valve (3).

Abstract: 177,442. Wheeler, J. A. June 9, 1921. Nuts; locking nuts; bolts.-A concavo-convex nut is secured to a bolt on flattening with a hammer, and is provided with h an interrupted thread of special construction which bites into the bolt. The nut 10 has a central hole 11 from which a number of slots 12 radiate. The central hole 11 tapers from the convex side 13 to the concave side 14, and has threads in the form of ratchet teeth having faces B<1> parallel to the nut faces and inclined faces 16 extending outwards towards the concave face of the nut. When the nut is flattened into engagement with a bolt, the slots 12 tend to close and form a continuous biting-surface. To tighten a bolt, the nut is further hammered, but to remove the nut a spanner is used in the ordinary way and the nut acts as a die. The nut can be used for forming a bolt-head, in which case a special form is employed in which the slots 12 are wider towards the centre in order to bite longitudinal ridges on the bolt when flattened, and prevent rotation. The nuts may be employed with piping &c. Another form in which the nut is shaped as the fastener of a cone is described, wherein the nut is forced into engagement with a rod by means of a hollow tool having a convex under face.

Title: Control device for dual-temperature refrigerators
IPC: G05D23/24
Filed: 1971-05-20
Abstract: 1335258 Automatic control of refrigerator temperature INDUSTRIE A ZANUSSI SpA 20 May 1971 [22 May 1970] 16114/71 Heading G3R A temperature control arrangement for a dualtemperature refrigerator comprises a first bistable MV including transistors 1, 2 and 15, Fig. 1 which controls the refrigerator compressor motor 34 via a relay 31, 32, and a second bistable M.V. including transistors 35, 36 which controls via a transistor 44 a heater 45 in the main storage compartment of the refrigerator.  The first bistable is controlled by an NTC thermistor 19 in the freezer and a thermistor 21 in the main compartment, such that if 19 and 21 simultaneously sense respective low temperatures the transistors 1 and 2 are cut-off so that transistors 15, 29 conduct and relay coil 31 is energized. Thereby the compressor motor 34 is switched OFF and a defroster element 33 is energized. The desired freezer temperature is pre-set on a potentiometer 48 and that of the main compartment on potentiometer 23. A transistor 24 is normally maintained conductive by a thermistor 26 also in the main compartment, and holds transistor 2 non-conducting. However when thermistors 21 and 26 sense too high a temperature T24 is caused to turn OFF thus switching ON T2 so that the relay 31 is deenergized and the compressor restarted. If the freezer thermistor 19 senses an excessive rise in temperature which is not experienced by the main compartment sensors then T1 is caused to conduct thereby restarting the compressor. A further thermistor 39 is located in the main compartment and controls the second bistable M.V. 35, 36 whereby to energize the heater element 45 if the temperature of the main compartment falls below a predetermined value. The control arrangement is such that the switching of the compressor between states in one sense, effects the resetting of the temperature at which the compressor is switched between states in the other sense, the stopping of the compressor being a function of R23.

Title: Improvements in or relating to the centrifugal casting of hollow bodies of metal
IPC: B22D13/10
Filed: 1924-07-08
Abstract: 238,055. Brown & Co., Ltd., J., and Bell, J. C. July 8, 1924. Casting-machines; metal-pouring; moulds.-In the centrifugal casting of thick hollow metal bodies the molten metal is delivered towards the descending wall of an uncooled mould through a number of nozzles r, Fig. 2, having relative reciprocating movement parallel to the mould axis and lateral movement to keep them at a constant distance from the inner face of the mould or of the cast metal. The mould a is supported by rollers b, 16, 18, Fig. 1, and rotated by fingers c engaging loosely in slots, chain f and a motor j. The nozzles extend from a pipe n lined with refractory material o, Fig. 2, closed at the end p and connected to a funnel q which is supplied from a sump 11 provided with an overflow 13 for slag &c. and a lip 12 for delivering the metal when the sump is tilted by an hydraulic cylinder 11<a>, Fig. 1. The funnel and pipe can be moved by a cylinder z, Fig. 2, laterally on a carriage s reciprocated axially by a cylinder w, Fig. 1. The pipe n may also be adjusted vertically by screws or its end p may be supported on roller &c, bearings. Before casting the mould and pipe n are heated to 100 to 120‹ F. by gas jets, not shown. After casting the carriage s is disconnected from the cylinder w and connected to a cable x driven by a winch y which withdraws the pipe and nozzles. After cooling the left-hand feathered flange k is removed and the cast body is withdrawn upon rollers 14. To ensure a uniform flow the cross-section of the nozzles r may vary. The speed of rotation of the mould depends on the diameter and rate of pouring; thus, for 50 inches internal diameter and 78 cwts. metal delivered in 102 seconds through five nozzles 1“ inch in diameter, the speed should be 220 revolutions per minute.
