Patent GB-231672-A (GB)
Title: Improvements in and relating to counting devices
IPC: G06M1/34
Filed: 1924-04-09
Abstract: 231,672. Robinson, J. W. April 9, 1924. Counters actuated by reciprocating- mechanism; zeroizing-mechanism.-In a counting-apparatus having a trip pointer 26, a totalizing counter 21 and a resetting-mechanism for the pointer a particular construction is described whereby the pointer is locked if the resetting operation is not complete. The actuating lever 2, reciprocated by the prime mover such as a liquid measuring and deliverina apparatus, has a pin 4 adapted at each oscillation to raise and lower a spring- influenced lever 6 pivoted at 7 and formed with a nose 9 to engage the teeth of a star wheel 11. The step by-step movement of this wheel is initiated by the lever 6 and is completed by the spring-produced pressure of a pawl 12. The shaft 15 carries, in addition to the star wheel 11, a finger for driving the total-counting train and a spur wheel meshing with another spur wheel 24 loose on a spindle 25. The pointer 26 is fixed to this spindle which is frictionally driven by spur wheel 24 under the pressure of a resilient dished plate 30, Fig. 6, held in place by a groove 31 and a stud 34 engaging a hole 35 in the plate. The spur wheel is thus pressed against a disc 28 secured to the spindle and formed with a nose 36. In the zero position of the spindle this nose displaces a spring pawl 37 so that its end 41 lies in the path of a tooth 53 on the hub of a bevel wheel 43 fixed to the zeroizing shaft 44, and engaging a similar wheel 46 mounted to drive spindle 25 frictionally under the action of spring 45 held in place by a collar 48 and pin 49. The zeroizing shaft is prevented from rotation in the wrong direction by a pair of detents engaging a wheel 54. Upon rotation of this shaft the wheel 46 is driven and restores the pointer to zero as defined by a stop 58, and the pawl 37 is forced into the path of tooth 53 to stop the rotation of the zeroizing shaft with a mutilated portion of its wheel 43 opposite wheel 46. Consequently the spindle and pointer are then free to be actuated but if on the other hand the zeroizing action is not carried through completely the wheels 42, 43 remain in gear and the pointer is locked against forward movement.

Convention date, March 25, 1930. [Class 142 (i).] Dobbies.-Steel balls n held in a cage or holder support feelers p connected to toggle levers r<1>, r<2> adapted to raise or lower hooks b connected to jack levers a for engagement with knives c, d. The balls rest on the pattern card l or pass through holes therein into recesses m in the card cylinder g, the balls sliding out of the recesses where the cylinders is turned. When the balls enter the recesses, the feelers p fall into the path of a reciprocating knife q and the corresponding hooks are raised for engagement with the upper knife c. After the shed has been formed, all the toggle levers are moved from the position shown in Fig. 1 to that shown in Fig. 2 by the action of a lever t to the left. The knives c, d and the card cylinder are operated by a crank f and the cam k through the mechanism shown. Since the toggle levers automatically lock in their extended position, the feelers p may be released and the card cylinder turned during the opening or closing of the shed, thereby facilitating the finding of a broken pick. In a modification, the balls u<1>, Fig. 6, are rotatably held in the ends of levers u arranged beneath the levers p. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of levers having rounded ends in place of the balls, and states that the invention is applicable to jacquards.

Title: Manufacture of 1:1:3-trialkoxyalkanes
Inventor: HALL REGINALD HAROLD
Filed: 1952-04-10
Abstract: 1 : 1 : 3-Tri-sec.-alkoxy alkanes are prepared by reacting an a ,b -olefinically unsaturated aliphatic aldehyde with a secondary aliphatic alcohol in the presence in the reaction mixture of a condensation catalyst and a water-entrainer under substantially anhydrous conditions, and removing, by distillation with an entrainer the water as it is liberated by the condensation reaction.  The expression "under substantially anhydrous condition" is used to mean that the amount of water present in the reaction mixture initially is less than 9 per cent by weight of the aldehyde.  In the preferred method, a mixture of the aldehyde, alcohol and entrainer is heated until no more water distils over whereupon the catalyst is added and heating continued to remove the liberated water forming in the condensation.  Suitable entrainers are benzene, toluene, methylene chloride, chloroform and isopropyl ether.  Specified catalysts are sulphuric, hydrochloric, phosphoric and organic sulphonic acids, boron trifluoride and its etherate, aluminium chloride, acid clays and acid zeolites.  A polymerization inhibitor may be present. Examples describe the production of tri-isopropoxy-propane and tri-isopropoxy butane from isopropanol and acrolein and crotonaldehyde respectively.

Title: An automatic return device for the pick-up arm of a record player
Filed: 1964-03-09
Abstract: 1,062,432. Gramophones. USINES GUSTAVE STAAR S.A. March 9, 1964 [March 12, 1963], No. 9885/64. Heading G5R. In a device for automatically returning the pick-up arm of a record player to the normal position at the end of a record, the pick-up arm is restored by energy stored in a spring by an initial manual movement of the arm to start the turntable. The pick-up arm 3, Fig. 2, is mounted on a hollow shaft 5 which carries a lever 31 and a cam 9 at its lower end; when the pick-up is displaced manually from its support 42 in the direction of arrow F2, the cam 9 engages a pin 10 and thereby rotates a lever 14 in direction F3 against its retaining spring 16 until it is latched against a fixed pin 44 by a retaining member 25. In this position the lever 14 closes a switch 51 to energize the motor and opens a muting switch 52. The lever 31 carries a cylinder 32 filled with viscous liquid in which a piston can rotate, the piston carrying an external lever 34 which can rotate to an extent limited by its engagement with a slot 37 in lever 31. A stop member 46 acting against lever 34 limits the manual rotation of the pick-up arm, and at the end of a record the increased radial movement of the pick-up arm causes lever 34 to engage the part 25<SP>1</SP> of the retaining member to release lever 14 and allow it to return to its initial position under the influence of spring 16. Movement of lever 14 opens switch 51 and closes switch 52 and causes a ramp (not shown) attached to the lever to raise a rod 18 and thereby raise the pick-up arm; further movement of the lever 14 causes a spring wire 39 attached to the lever to engage a pin 38 depending from lever 31, thereby rotating lever 31 and the pick-up arm until the latter engages a raised edge 42<SP>1</SP> of its support, and the final movement of lever 14 causes the ramp to move under the rod 18 and lower the pick-up arm to its rest position.
