Abstract: 639,051. Railway signals. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. March 14, 1947, No. 7110. Convention date, May 2, 1946. Drawings to Specification. [Class 105] Searchlight-spectacle signals, colour light signals or position-light signals have one or more of the light beams periodically interrupted at a code rate by an electromagnetically operated shutter supplied at the proper time with current coded appropriately to the particular signal. A proceed signal is flashed at 180 times a minute, a caution signal at 75 times a minute, but a stop signal has a steady light. The shutter is in movement only when a particular signal is to be given and in the de-energized state blocks the light aperture to prevent entry of light and the reflection of a phantom signal; any phantom signal which might arise would not be interrupted and the driver must therefore stop and investigate.

Abstract: 1307081 Safe-load indicators BALDWINLIMA-HAMILTON CORP 17 Feb 1970 [17 Feb 1969] 7483/70 Heading B8B [Also in Division E1] A safe-load indicator for a material handling device is shown applied to a mobile crane 10 with an extensible boom 14 mounted for luffing at pivot pin 20 on a support 18 arranged for slewing on a vehicle 12. The indicator includes a boom orientation responsive linkage 46 with a support arm 62 pivoted at 70 on boom base section 16 and having a horizontal leg 63 maintained always horizontal by a parallelogram effect due to link 67 pivoted thereto and to the support 18. The linkage 46 comprises first and second parallel arms 72, 74 respectively pivoted at 68, 70 to the leg 63 at their lower ends, and at 76, 78 at their upper ends to opposite ends of a horizontal leg 80 of a T cam follower bar assembly 82 including a ventical leg 84 with a slot 86 therein. The slot 86 receives a roller 87 which is part of a boom extension responsive assembly 50. comprising as spring, motor 104 tensioned to reel in a cable 108 attached at its free end to boom head block 28. Bevel gears 112, 114 drive a screw-shaft 116 on which is threaded a. travelling block 120 carrying the roller 87. The linkage 46 thus pivots one way. in response to raising of the boom 14 and in the opposite direction in response to extension of the boom. 14, the position of the linkage being indicative of the maximum permissible moment allowable. One or other of. two potentiometers 142, 144, adjusted from the linkage 46 by drive links 132, 158, is selected by a switch 154 to correspond to operation with or without outriggers and the selected output, representing the allowable load moment, is passed to an indicator assembly 44 where it is compared with the load moment; measured by a strain gauge 40 connected to pivot pin 23 of luffing cylinder 22. A meter 58 is calibrated to show percentage of the permissible moment and a light 60 warns of an overload condition.  A linkage movement modifying mechanism 48 is connected by a push-pull cable 124 to a cam bar 122 pivoted to a block 118 and contacted on its, lower face by a roller 121 on the travelling block120. The lower face of the cam bar 122 is cut to correspond to the required permissible load moment curve, Fig. 2 (not shown), and may thus take into account the crushing strength of the boom 14 when operating at a small working radius, as well as the normal tipping effect.

Abstract: 732,810. Treating wood. HUDSON, M. S. March 20, 1953, No. 7793/53. Class 140. In the vapour drying of wood in a closed space with a potentially explosive organic vapour at elevated temperatures and subsequently admitting air into the closed space in an amount such as to produce an explosive mixture with the organic vapour, steam is introduced into the closed space before or during the admission of air until an initial pressure not exceeding 20 pounds per square inch is set up in the closed space and the partial pressure of steam therein is at least equal to the partial pressure of the organic vapour. The steam may be introduced to break the vacuum applied at the end of the drying process ; in order to prevent undesirable absorption of water in cases where a relatively high degree of drying has been effected, the closed drying space may be first opened to the atmosphere followed by introduction of steam. A preservative treatment may follow the drying in the closed space, the admission of the preservative immediately following the admission of steam. Specifications 655,062 and 655,063 are referred to.
