Patent GB-1399913-A (GB)
Title: Logic circuits
IPC: G11C19/18
Filed: 1972-07-05
Abstract: 1399913 Shift registers TELETYPE CORP 5 July 1972 [12 July 1971] 31390/72 Heading G4C [Also in Division H3] A shift register comprises a plurality of logic inverters 62, 63 driven by two clocklines # 1 , # 2 . A signal at terminal 10 is passed to capacitor 20 when the clock pulse # 1  makes transistor 14 conductive. Capacitor 32 is also charged via transistor 26. If the signal is sufficient to turn transistor 28 on the capacitor 32 is discharged when the clock signal goes to ground. If there is no charge, the capacitor 32 remains charged. When clock signal # 2  subsequently occurs transistor 42 passes the signal to capacitor 48 etc. Capacitor 70 gives a negative pulse at point 34 which makes transistor 28 more conductive to discharge capacitor 32 when there is said sufficient charge on capacitor 20. Similarly, capacitor 80 provides a negative pulse at point 41 to increase the conductivity of transistor 42 when clock signal # 2  occurs thereby enabling a larger signal to be passed to capacitor 48. Capacitors 92 and 72 correspond to the respective capacitors 70, 80.

Title: Improvements in clutch-controlling mechanism for agricultural tractors and the like
IPC: B62D49/06
Filed: 1947-11-29
Abstract: 634,480. Operating clutches. MORRIS MOTORS, Ltd., MERRITT, H. E., and FOWERAKER, D. B. Nov. 29, 1947, No. 31619. [Class 80 (ii)] Relates to auxiliary hand or overload clutch release mechanism for an agricultural tractor or similar vehicle and comprises a normal clutch pedal 1, Fig. 1, and a hand clutch lever 16 both freely mounted on parallel shafts or, as shown, the same shaft 2, a trip mechanism including a detent lever 5 which is rigidly coupled to the clutch-operating linkage 3, as via the shaft 2, and is connected to the clutch pedal 1 by a preloaded spring 6 sufficiently powerful to overcome the normal clutch-engaging springs, and a spring-loaded pawl 8 pivoted to the pedal 1 and normally latching the detent lever 5 so that the clutch pedal functions ordinarily, the pawl being operable, either by the lever 16 or by means responsive to the occurrence of an overload, to release the lever 5 and thereby cause the spring 6 to effect clutch disengagement. As shown, an extension 17, Fig. 3, of the lever 16 co-acts with a sear 19 on the pawl 8 to release a roller 12 on the lever 5 from a notch 11 on the pawl as the lever 16 is pushed forward (to the left in the figures). A step 21 on the pawl arrests the extension 17 and prevents it contacting the roller 12, with possible unintentional clutch re-engagement, until the roller has moved sufficiently along a straight surface 22 on the pawl to depress the step 21 clear of the extension 17, when further forward movement of the lever 16 will effect such re-engagement, the spring loading again disengaging the clutch as soon as the lever 16 is released. In this way an operator dismounted from the tractor can safely control the clutch through the lever 16. The mechanism is re-set for normal clutch operation by depressing the pedal 1 until the roller 12 re-enters the notch 11. A torsion spring 23 normally holds the lever 16 so that an extension 20 thereon abuts the pedal 1. Rearward movement of the lever 16 operates the clutch normally through this extension. The pawl 8 may be linked to a yielding device in the tractor draft connection so as to be moved sufficiently to release the roller 12 and disengage the clutch when the draft pull becomes excessive.

Title: Improvements in Processes for the Distillation and Refining of Volatile Substances and also the Carbonisation and Coking thereof.
Inventor: MAXIM-JODEL BERG
IPC: C10B55/02
Filed: 1919-12-22
Abstract: Hydrocarbons and other substances are refined by distilling them in admixture with another substance which evolves vapours at a lower temperature.  In an example, a residue of Galician petroleum oil, boiling at over 350 DEG  C., is mixed with dry wood flour (sawdust) and distilled.  The distillation of the liquid is complete at 300 DEG C., a carbonized residue being obtained.  The distillation of the liquid is thus effected at a lower temperature and decomposition is minimized.  The asphaltic constituents are absorbed by the solids in the still, and the charcoal and the vapours of acetic acid and methyl alcohol exert a refining action on the oil distillates.  The hydrogen evolved reduces the unsaturated hydrocarbons to saturated hydrocarbons, the charcoal acting as a catalyst.
