Filed: 1937-12-07
Abstract: 507,006. Refrigerating. ELECTROLUX, Ltd. Dec. 7, 1937, No. 33834. Convention date, Dec. 8, 1936. [Class 29] Control of the defrosting period of a cabinet evaporator or cooling body 12 is effected by two thermally sensitive elements, one 32 being located at the part at lowest temperature in normal operation and the other 31 located at that part which during the defrosting period is either the coldest or remains coated with ice for the longest period. The cooling body 35 enclosing ice-making recesses has usually smooth side surfaces on which ice does not readily accumulate, whereas the upper surface accumulates ice from the relatively warm air, and accordingly the conduit 31 from the thermal element 32, which effects control of the fuel valve 29 of a generator 10 in the usual manner, is placed so as to be sensitive to the temperature of ice accumulated at the upper part of the evaporator. By this arrangement the fuel valve-is held closed to allow defrosting to continue until the ice is completely removed. The refrigerating system shown is of the known inert gas absorption type, with the absorber 13 cooled by a closed-cycle heat transfer system 17, 18. The evaporator has a cabinet-cooling portion 34 and if desired this portion may be provided with a thermally sensitive control member or be contacted by a portion of the conduit 31.

Title: Improvements in or relating to matrix-setting and single-letter-casting or line-casting machines
IPC: B41B27/00
Filed: 1927-12-16
Abstract: 307,968. Wade, H., (Standard Compositor Akt.-Ges.). Dec. 16, 1927. No Patent granted (Sealing fee not paid). Assembling matrices; keyboards.-In single-type casting or type-line-casting machines of the kind in which an assembled line of matrices is conveyed, upon depression of a key, to an elevator, which first transports them to the mould and then to the distributor, means is provided for locking the line-transferring key except when the elevator is in position to transport a new line to the mould. In one form, the line-key 2, Fig. 2, is connected by a lever 6 and a link 7 to an arm 8 on a shaft 9, to which is secured a two-armed lever 12. One arm of the lever 12 engages a pushrod 13, which actuates mechanism to cause the matrix line to be conveyed to the elevator. An abutment 16, which overlies the other arm of the lever 12, is carried by a sliding spring-pressed rod 15, connected at its lower end to a two-armed lever 20. A roller 21 on the lever 20 lies in the path of one of the side-plates 23 of the elevator 22.. When the elevator is in position to receive a new line, as shown in Fig. 2, its engagement with the roller 21 holds the abutment 16 above the lever 12, so that the line-key is free to be operated. On the descent of the elevator towards the mould, the roller 21 escapes from the elevator, and the rod 15 draws down the abutment 16, so as to lock the lever 12 and the line-key. On the descent of the elevator from the distributing to the assembling position, the plate 23 again engages the roller 21 in such a manner as to raise the abutment 16. The line key may, alternatively, be locked by electromagnetic, pneumatic, or hydraulic means.
Patent GB-396598-A (GB)
Title: Hydraulically-controlled infinitely-variable transmission mechanism
IPC: F16H3/72
Filed: 1932-12-02
Abstract: 396,598. Variable speed gearing; oscillating -cylinder pumps. STEADMAN, A. H., 23, Haigville Gardens, Ilford, Essex. Dec. 2, 1932, No. 34146. [Class 80 (ii).] Relates to variable-speed gearing comprising epicyclic gearing controlled by pumps pumping oil which is throttled under manual control. The driving-element is a casing 1, Fig. 1, rigid with a primary sun gear 2 loose about a main shaft 4. The driven element is a carrier 44 of bevel planets meshing with side gears 41, 42 of a differential train. Fast on the main shaft 4 is the gear 41 and a revoluble drum 3 forming the carrier of stepped planets 10, 11 meshing respectively with the primary gear 2 and with a secondary sun gear 12. The gear 12, which is larger than the gear 2, is fast on a sleeve 13 to the other end of which is secured the gear 42. When the driven element 44 is at rest, the shaft 4 and sleeve 13, and therefore the drum 3 and sun gear 12, are rotating at equal speeds in opposite directions. The forward variable drive is effected by reducing this relative rotation of the drum 3 and gear 12. To this end, planet gears 15, Fig. 2, meshing with the gear 12 each carry a balanced crank 21 with a bearing shoe 20 secured to the plunger 18, Fig. 4, of a pump 16 which oscillates on trunnions 17 in the drum 3. As the drum 3 turns clockwise of Fig. 2, scoops 40 pile up pressure oil in front of the inlet valves 39 of the pumps. The sectional area of the plunger stem 18, Fig. 4, is half that of the bore of the barrel 16 which is filled by the pump piston 19. Within the piston is a ball valve 36. As the piston descends, a volume of oil equal to that moved through by the piston passes the ball 36 upwards through ports 35. Half is expelled through a channel 22, and half remains around the stem 18 to be expelled on the upward stroke of the piston. The pumps are thus doubleacting, so that oil is delivered centrally through pipes 24 and pressure builds up in an annular chamber 25, Figs. 1 and 3, which resists the action of the pumps. The chamber 25 is closed by a ring of spring-pressed balls 26 which are thrust positively outwards, to relieve the pressure and so to slow down the driven member 44, by sliding manually a sleeve 30, Fig. 1, with a tapered end 31 adapted to engage the balls simultaneously or in succession. The oil escapes by a central chamber 28 into the drum 3. To effect reversed driving, which is wholly mechanical, a brake is applied to a drum 46 rigid with the sleeve 13. The drum 3 turns backwards round the stationary gear 12 carrying the gear 41 with it and the member 44 follows at half speed, the gear 42 being also stationary.
