Title: Central buffer and draw gear for railway vehicles
IPC: B61G9/12
Filed: 1933-09-04
Abstract: 410,999. Combined buffing and draw gear for railway vehicles. SKODA WORKS, PLZEN, 37n, Jungmannova, Prague. Sept. 4, 1933, No. 24519. Convention date, Sept. 2, 1932. [Class 103 (v).] Relates to an arrangement of the central buffing and draw gear of a railway vehicle, particularly in effecting a replacement of the side buffers and non-automatic hook couplings by central buffer couplings, whereby buffing shocks during the transition period are absorbed mainly by the side buffers, while in the ultimate form the central buffer couplings are associated with a continuous draw-gear which distributes the draught and buffing stresses to all the vehicles and avoids the necessity of strengthening the underframes. For this purpose the ultimate coupler 1, which during the transition period is fitted with an auxiliary coupling 2, is pivotally and yieldingly mounted on a draw-bar 6, which in turn is adapted to slide with a certain amount of lost motion determined by a pin and slot connection 7, 8 on a bar 9 forming part of the spring member 10 of a buffing and draw-gear disposed at the centre of the vehicle, an additional light return spring 11 being located between the vehicle frame and a collar 12 on the bar 6. Thus, in the transition period, buffing shocks are absorbed mainly by the side buffers, the spring 11 also being compressed to some extent, while the gear 10 does not come into effect unless the shocks are of sufficient violence to displace the bar 6 to the limit of its lost motion. Ultimately, the auxiliary coupling 2, side buffers, and the spring 11 are removed, and the bar 6 is pushed inwardly and made solid with the bar 9 either by welding or by inserting a wedge in the slot 8, thus effecting a conversion to a continuous draw-gear. Specifications 389,656 and 400,130 are referred to.

Abstract: 1,058,840. Conveyers. PACO CORPORATION. June 16, 1964, No. 24844/64. Heading B8A. Freshly moulded concrete blocks 27 on pallets 28 are carried on an endless conveyer 7 from a moulding machine 6 to a fresh block elevator 8 where eight pairs of the pallets 28 with blocks 27 are accumulated in a vertical column on pairs of brackets 37 attached to chains 33 (Figs. 3, 5), the leading pallet 28 of each pair being pushed on to and supported by idler rollers 38 before being picked up with the succeeding pallet 28. This action is indicated by arrows 75 in Fig. 2. The column of fresh blocks is now transferred to one of four compartments 9<SP>1</SP> in an auxiliary rack 9 arranged for movement past the fresh block elevator 8 and a dry block elevator 13 (similar to elevator 8). This transfer is made by a fresh block off-bearer 10 similar to a dry block off-bearer 14 comprising fingers 56 attached to a vertical beam 55 carried on rollers 64 for horizontal movement arid provided with a small vertical lifting movement. At the start of the cycle the rack 9 is in its right hand limit position, compartments 9<SP>11</SP> are empty and opposite elevator 5 while the compartments 9<SP>1</SP> have been loaded with fresh blocks. The elevator 3 is in the up position fully loaded with dry blocks. A main off-bearer 11 with four sets of fingers follows path 81, Fig. 2, to transfer simultaneously all the dry blocks from the rack 3 into the compartments 9<SP>11</SP>. The rack 9 then immediately moves to the extreme left position and the off-bearer 11 follows path 78 to transfer the fresh blocks from the compartments 9<SP>1</SP> to the rack 3. The freshly loaded rack 3 is lowered into an annular boat 2 floating in water in an annular basin 1 defining an enclosed kiln in which steam is injected at different locations around the length thereof to effect curing and drying of the fresh concrete blocks 27, path 83, 82, Fig. 2. When the rack 3 has been lowered into the boat 2 movement of the boat 2 brings a rack of cured blocks 27 to the elevator 5. The movement of the boat is slow and during the time taken the rack 9 is moved to the extreme left position and the cured blocks 27 in the right compartment 911 are transferred to the dry block elevator 13 by the off-bearer 14 in accordance with path 77. The rack 9 then moves one step to the right and, immediately after, fresh blocks 27 are transferred from the elevator 8 to the right compartment 9<SP>1</SP>. This is repeated until the dry blocks 27 are all unloaded from the compartments 911 and the compartments 9<SP>1</SP> are fully loaded with fresh blocks 27. The elevator 13, when fully loaded, lowers the dry blocks 27 and deposits them in succession on an outgoing conveyer 15, path 75<SP>1</SP>, Fig. 2. Similarly when elevator 8 has been emptied it starts its step-wise upward movement to be loaded with fresh blocks from the conveyer 7. The next rack 3 with dry blocks is raised from the boat 2 and the cycle repeated.

Title: Improvements in and relating to the manufacture of cast iron
IPC: C21C1/00
Filed: 1933-09-09
Abstract: In the manufacture of cast iron titanium or an alloy containing titanium is added to the charge or to the molten iron and the titanium in the melt subsequently oxidized either by passing an oxidizing gas such as air or carbon dioxide through the melt or by adding a solid oxidizing agent, such as a carbonate or an oxide, to the melt.  After the oxidation of the titanium hydrogen may be blown through the melt so as to coarsen the graphite in the iron. Instead of hydrogen, hydrogen-containing compounds such as steam or hydrocarbons may be used.  If too much hydrogen is dissolved in the molten iron, the excess of hydrogen may be removed by blowing nitrogen, air, or carbon dioxide through the molten metal.

Title: Torpedo-launching apparatus, more particularly for fast-moving ships or scouts
IPC: F41F3/08
Filed: 1931-09-11
Abstract: 365,028. Launching torpedoes. SOC. ANON. DES ATELIERS ET CHANTIERS DE LA LOIRE, 4, Rue de Teheran, Paris. Sept. 11, 1931, No. 25531. Convention date, Sept. 25, 1930. [Class 9 (ii).] In a torpedo launching apparatus especially intended for fast-moving ships and comprising a frame mounted on longitudinal pivots and adapted to be swung out and down to launch the torpedo, means are provided to start the propelling motor of the torpedo automatically just before the torpedo is released. As shown in plan in Fig. 3 and in section in Fig. 1, the torpedo a is held against crutches p on a tube c by a pair of jaws b hinged at b<1> and locked by a lever lying between the tail ends b<2> of the jaws b. The tube c is hinged to curved arms e mounted on the edge of the ship on longitudinal pivots e<2>, and is connected by a rod f to a plunger f<2>, Fig. 4, movable in a cylinder f<1> which forms a continuation of a cylinder g containing another plunger h. Normally, the plunger f<2> which is provided with a hook f<3> is held in place by a pivoted catch i locked by the plunger h. To launch the torpedo, compressed. air is admitted between the plungers by a port g<1> and forces the plunger h back against a spring h<1> and away from the catch i. The plunger f<2> now released is pushed out by the compressed air and swings the arms e out round their pivots e<2>. During this movement, a sleeve l, Fig. 8, at the end of the tube c is drawn by a line n attached to a fixed point on the ship and compresses a spring m. Near the end of the movement, a notch l<2> in the sleeve comes opposite a pivoted catch o and allows this catch to swing out and release a rod k slidably mounted in the tube c. The rod k is then moved along the tube c by the compressed spring m. A finger k<1>, Fig. 3, on the rod first trips the starting lever of the torpedo motor ; then a shoulder at one end of a slot k<2> in the rod k strikes one arm of the bell-crank lever d and moves this lever away from the tails b<2> of the jaws b, which are thereupon opened out by the weight of the torpedo ; the torpedo is thus launched with its motor previously started. The plunger h may be operated from outside the cylinder g by a handle h<4> and may be secured in either of its extreme positions by a pin inserted through a hole in the cylinder and through either of two holes h<2>, h<5> in the stem h<3> of the plunger. The pivots e<2> of the arms e are provided with spring- controlled cams to cushion shocks and to tend to maintain the arms in the raised position.
