Title: Improvements relating to starting arrangements for diesel engines
IPC: F02P19/02
Filed: 1961-03-10
Abstract: 909,200. Starting prime movers. DAIMLERBENZ A.G. March 10, 1961 [March 15, 1960], No. 8879/61. Class 38 (4). [Also in Group XXVII] Means are provided which indicate the expiration of an engine temperature dependent combustion space pre-heating period for a diesel engine, or one which automatically brings an engine starter into operation at the termination of the above period. When an actuating button 6 of a switch 4 is pulled to a position 7, a plug 2 in a diesel engine 1 is brought to an incandescent state by current through a lead 3, so as to pre-heat a combustion chamber 5. By the same action, a time switch 10 provided with a signal lamp 11 and connected to the switch 4 is brought into action. A temperature-responsive switch 12 mounted on the time switch 10 is connected through lead 13 to a temperatureresponsive device 14 in the cooling water jacket 15 of the engine or, if it be air-cooled, in the lubricating oil of the engine. The device 14 transmits a signal to the switch 12 which is engine temperature dependent and thus causes the signal lamp 11 to light after a period of preheating, the duration of which is also engine temperature dependent. When the indicating lamp 11 has come " on " the button 6 may be pulled into a position 7<SP>1</SP> so that an engine starter motor, not shown, may be actuated through a lead 8. Releasing the button 6 causes it to be returned into its original position by the action of a spring. The termination of the pre-heating period may be arranged to result in the automatic actuation of the starter motor, only two positions of the button 6 then being required. A press button is arranged so that the starter may be manually actuated, by operating both the switches. A further switch in the lead 8 to the starter motor is arranged to prevent its inadvertent operation if the clutch and a gear have been left engaged. The temperatureresponsive switch 12 and/or the time switch 10 may operate so as to provide a small number of different periods each proportional to a different " band " of temperature. The signal lamp 11 may be combined with an indicating device which enables the operation of the plugs to be checked, thus, the lamp might glow dimly when the plug is operating and then increase in its intensity at the completion of the pre-heating period.

Title: Improvements in telephone alarm call systems
IPC: H04M3/432
Filed: 1944-05-11
Abstract: 577,258. Time alarm signals. MERCER, R. (Automatic Electric Laboratories, Inc.) May 11, 1944, No. 8360. [Class 118 (ii)] [Also in Group XXXIX] A telephone exchange is provided with apparatus for automatically ringing certain subscribers at pre-determined times of day. A common timecontrolled step-by-step switch G which makes one rotation in 24 hours and may for example rest for 7¢ minutes on each contact and also between adjacent contacts connects up in turn a series of relays D, each of which is common to the group of subscribers to be called at the corresponding time. Relays A, B, C are individual to each subscriber's line and a common relay E which energizes momentarily over cam F once per minute connects up relay B of each line associated with the operated relay D, provided the line is not busy. Relay B locks and applies ringing current to the line through ring-trip relay A which responds upon reply and lights lamp L1 individual to the subscriber. The ringing may be continuous or coded to distinguish the alarm call from an ordinary call. If the line is busy, relay C is operative and relay B is disconnected, and further tests are made when relay E energizes again. A pair of relays H, J which operate in succession over time-controlled cams K after relay D has energized and lock up as long as any relay A of the group remains unoperated serve to connect up an alarm bell AB and lamp AL a certain time after the calls are initiated, so that an attendant may check which lamps L1, L2 ... remain unlighted and take any necessary action. Relay D falls back when the switch G steps on and unlocks all relays A, B. In a modification, relay E and cam F are eliminated and a common group of lamps L1, L2 .... serves successively for the different groups of subscribers. Also, relay B is released by the operation of relay A so that the line is rendered free as soon as the alarm call is answered.

IPC: C10G1/02
Filed: 1927-04-05
Abstract: 295,225. White, A. E., (International Bitumenoil Corporation). April 5, 1927. Coking processes; retorts.-A rotary retort for the distillation of oil shale or other carbonaceous materials is divided into zones of increasing temperature, the hot gases for externally heating each zone being used for heating a series of stills each working at a different temperature and through which the oil derived from the retort charge is passed in series. Crushed shale is fed from a hopper 8 by a worm 10 into an inclined rotary retort having double walls 20, 21 between which is packing 22 separated by air spaces 88 dividing the retort into sections or zones each heated in a separate combustion chamber 30, 32, 32a, 32<b> by burners 36. The shale is gradually heated during its passage through the retort until when it reaches the hottest zone the volatiles are suddenly evolved at the discharge end of the retort when the residue falls into a discharge tube 12 and the distillates pass through a rotary screen 18 to remove the dust, the particles of which are dislodged by a brush 19. The distillates are led by a pipe 16 to a collecting-chamber 61, a pump 62 maintaining a partial vacuum and delivering the vapours by a pipe 60 to a watercooled condenser 63. A valve 65 controls an outlet for the permanent gases. The condensed oils from the coil 63 pass by gravity through the stills 48 - - 51 each of which is heated by the hot waste gases from each zone of the retort, openings 47 being provided to admit the hot gases from the combustion spaces below the retort. Each still has a separate condenser 55 - - 58. Still 51, which is the most highly heated, is maintained at a pressure of several atmospheres and serves to increase the gasoline production by cracking the residues of the kerosene and lubricating-oil stills 56, 57, and the paraffin condensate from the chamber 61. A residue receiver 68 is provided with a pipe 66 for the paraffin condensate and a pipe 69 for the kerosene condensate, and is connected by a pipe 71 with the still 50, a pump 78 forcing these residues into still 51 which is maintained at 800‹ F. and from which a pipe 59 leads to the condenser 58 for cracked oil.
