Title: Improvements in or relating to steering means for endless track driven vehicles
IPC: B62D11/22
Filed: 1935-12-23
Abstract: 455,949. Endless - - track vehicles. AGAHD, W., 213, Kurf³rstendamm, Berlin. Dec. 23, 1935, No. 35544. Convention date, Jan. 15. [Classes 79 (i) and 79 (v)] Steering mechanism for endless-track vehicles comprises means for swivelling the supporting or track rollers and simultaneously displacing them laterally of the chassis so that the distance between corresponding rollers of the two tracks is varied and the rollers on the inside of a curve are adjusted to a smaller radius than the outer rollers. In the construction shown in Fig. 3, the vehicle is provided with fixed outer axles a having track rollers b, and inner axles c<1>... c<5> which are slidable for steering and are connected to track rollers d<1> .. d<5>. The axles are slid to varying extents by means of pins e on the axles engaging slots f on a slidable plate y. When the axles are moved the rollers d<2>, d<3>, d<4> are given an additional movement, being mounted on cranks i which are pivoted at h to the axles and have arms l having slidable pivot connections with pins m fixed on the chassis. Thus, when each axle c<2>, c<3> or c<4> is moved its rollers at each end are brought nearer to the centre of the axle and the inner rollers are set to a curve of smaller radius than the outer rollers. Simultaneously with the bodily movement of the rollers d<2>, d<3>, d<4>, the rollers d<1>, d<2> and d<4>, d<5> are swivelled to varying extents by means of levers n connected by pins w<1>, w<2>, to the axles and having spaced pivots ql, q<2> for links p<1>, p<2> connected to arms on the roller pivots. Thus the relative movement between the axles c<1>, c<2> and c', c<5> swivels the rollers on the ends of these axles accordingly. The rollers may be connected to the axles by eccentrics instead of the cranks i. In the construction shown in Fig. 1, the rollers d<2>, d<3> d<4> are mounted on half-axles c<20>, c<30>, c<40>, each half axle having a pin e<11> controlled by a separate slot f<11> in the slidable plate y, these slots being so inclined that movement of the plate y slides the halfaxles and also shortens the distances between their ends carrying the rollers. The rollers are simultaneously swivelled in the same manner as in the construction shown in Fig. 3. In a modification, Fig. 4 (not shown), the half-axles slide in a tube which is moved by the slots f and are brought nearer together in this tube by linkage.

IPC: F24C3/04
Filed: 1960-10-18
Abstract: 918,712. Gas fires. PARKINSON COWAN Ltd. Sept. 28, 1961 [Oct. 18, 1960], No. 35624/60. Class 126. In a radiant gas fire the outlet from a rectangular combustion chamber 3 is restricted by means of a rib 8 formed integrally along the upper edge of the front wall 5 of the combustion chamber. Radiant bars 7 are mounted in front of a fire-back 4, the lower part of which forms the rear wall of the combustion chamber, parts 4, 5 and 7 being made of fireclay. The rib 8 extends across approximately one-third of the top of the chamber 3 and tapers rearwardly in cross-section. It is stated that the inclusion of the rib results in a more unform heating of the radiants and also in a reduced probability of combustion gases passing between the radiants and into the room.

Title: Oxygenated 18-steroids and process for their manufacture
IPC: C07J71/00
Filed: 1958-11-06
Abstract: The invention comprises (1) a process for the isomerization of the 17a -side chain of a steroid of the formula <FORM:0901614/IV (b)/1> (wherein R is an oxo group or a hydrogen atom and a free or esterified hydroxyl group, R1 is hydrogen or a free or esterified hydroxyl group, and R11 is a free or ketalized oxo group) which must also contain a double bond starting from the 5-carbon atom, to the 17b -side chain by treatment with an alkaline agent; and (2) the above 17-iso steroids per se.  The isomerization may be effected with an alkali metal alkoxide, hydroxide, carbonate or bicarbonate or with a strong organic base or with aluminium oxide, in an aqueous or anhydrous solvent; and it results in an equilibrium mixture of the two isomers from which the desired 17b -compound can be obtained by, for example, chromatography or fractional crystallization.  Ester and ketal groups can be concomitantly or subsequently hydrolysed and free keto and hydroxyl groups previously or subsequently esterified or ketalized.  The starting materials are formed by alkaline treatment of the corresponding 17b -compounds, and are racemates or the corresponding enantiomeric forms.  Examples illustrate all the above processes and interconversions.  An extensive list of esterifying acids is also provided.  Also described is the preparation of the (18-->11) lactone of d, l-D 5-3-ethylenedioxy-11b -hydroxy-20-oxo-21-acetoxy-pregnene -18-acid and the corresponding 17-iso compound from the 21-iodo compound and potassium acetate, and their separation by chromatography.

Abstract: 411,395. Thermionic distributers. NAAMLOOZE VENNOOTSCHAP MACHINERIEENEN APPARATEN FABRIEKEN, 30, Croeselaan, Utrecht, Holland. Dec. 29, 1933, No. 36649. Convention date, Jan. 3. [Class 40 (v).] In apparatus for the selective choice of receivers over a common link and employing synchronism of the start-stop type, synchronism is effected by sending impulses each of which produces at the receiver a series of successive impulses whose total duration is smaller than the period of the synchronizing impulse. A synchronizing impulse coming over the line L is applied through a transformer q to the grid of valve 1 which becomes conducting and discharges condenser c1 in its anode circuit. When this anode current begins to diminish, the positive voltage induced in the secondary of a transformer u1 also in the anode circuit, is applied through a choke s2 to the grid of valve 2 which in turn becomes conducting. In a similar way, valves 3 and 4 become successively conducting and when the condenser c4 has discharged through valve 4, the cycle is complete and recommences when a further impulse comes over the line, the condensers c1 - c4 being recharged from a source g through resistances r1 - r4. The secondary windings of the transformers u1 - - u4 are connected to receivers e1 - e4, and while any individual valve is conducting, signals may be sent to its associated receiver, being applied through transformer p to all the transformers u1 - u4. The valve grids are normally negatively biassed from sources n for valve 1 and m for valves 2, 3, 4.

By this means tool transfer can take place at any position of the headstock 50. The pendulum includes a gripper 3 and is moved by an hydraulic or pneumatic jack 20, or by electrical or electromagnetic drives or by rack gears. For constant orientation of a tool the pendulum 2 and link 8 may be constructed as a parallelogram and, for lateral rigidity, may be double-banked. The links and pendulum may be movable laterally and the gripper 3 may be movable relative to the pendulum perpendicular to, or parallel to, the plane of movement of the pendulum. A machine tool may include two pendulum and link mechanisms for moving a tool from the storage means to the spindle and vice versa. The mechanism may be used in connection with transfer mechanism at the storage means and spindle for taking a tool from the gripper 3 and placing it in the storage means or spindle and vice versa. In a machining cycle using only four tools, two pendulums are used with only one storage space. For a cycle using only three tools the pendulums are locked at their positions adjacent the spindle and the transfer mechanism effects the tool change. Reference has been directed by the Comptroller to Specification 916,501.

Abstract: 823,657. Fluid pressure brakes. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Nov. 26, 1957 [Dec. 3, 1956], No. 36876/57. Class 103 (1). A relay emergency valve 14 which in normal braking applies fluid pressure from a reservoir 12 to brakes 10 on actuation of a relay piston 30 having an exhaust passage 34 therethrough and movable to first close an exhaust valve 48 and then move an inlet valve 58 to open an inlet passage 86 in response to pressure variations in a service line 4, has an emergency piston 70 formed with the passage 86 and normally maintained in a first position by pressure from an emergency line 6 and movable on loss of pressure in this line to close exhaust valve 48 and open inlet valve 58 to apply the brakes. The emergency reservoir 12 is charged from a main reservoir 2 and a compressor through pipe 6, port 20, one-way valve 22 and port 24 to a pressure lower than that in reservoir 2 depending on the spring controlling valve 22. On brake application, increase of pressure in chamber 38 of relay valve 14 forces piston 30 downwards against spring 44 to close exhaust valve 48 and open inlet valve 56 to connect reservoir 12 through ports 24, 96, chambers 72, 40 and port 42 to brake actuators 10, the valves 48 and 56 being integrally connected. Since the areas of piston 30 exposed to chambers 38 and 40 are nearly equal, the pressures at ports 26 and 42 will be equal; when the pressures above and below piston 30 are equal the spring 44 returns the piston 30 upwardly until the valves 48, 56 are in the lap position; on increase of pressure in chamber 38 piston 30 moves down to open inlet valve 56 to increase the pressure in the brake actuators, and should it decrease then the piston 30 moves further upwards to open the exhaust valve 48 and release to atmosphere via bore 34 in piston 30 and filter 37 the excess pressure in the brake actuators until balance is re-established. If the emergency pipe 6 is broken, loss of pressure above the emergency piston 70 and due to pressure from reservoir 12 acting on the lower side, the piston 70 is forced upwards to close exhaust valve 48 and rapidly open valve 56 to charge the brake actuators, the stem 60 of valve 56 slides in a cavity 88 in a cap-nut 76 screw-threaded to piston 70 and held in relay valve casing 18 by cap-nut 90. With a slow leak in the emergency pipe the brakes are applied gradually. An orifice 98 is provided in port 26 to prevent chattering of the inlet and exhaust valves in the lap position caused by pressure surges in chamber 38. The relay valve 14 and reservoir 12 may be mounted on a trailer vehicle, the actuators 10 applying the trailer brakes, whilst reservoir 2 and valve 8 are on the tractor vehicle. In an embodiment in Fig. 2 (not shown), the pressure from reservoir 2 on piston 70 is balanced by a spring between cap-nuts 76 and 90, and during initial charging of the system pressure is routed to the brake actuators as well as reservoir 12 since the spring holds the valve in the emergency position so holding the brake applied until sufficient pressure is stored in reservoir 2.
