Title: Improvements in or relating to time-controlled switches or other relays
IPC: G04C23/16
Filed: 1946-01-15
Abstract: 606,468. Time switches. SMITH & SONS (ENGLAND), Ltd., S., and MOSS, E. B. Jan. 15, 1946, No. 1389. [Class 38 (v)] The time-setting device of a clockwork-actuated switch consists of a differential epicyclic gear having two sun-wheels and a compound planetwheel, the gear ratios of the sun-wheels and the corresponding gears on the planet-wheel being different. Fig. 2 shows a clockwork mechanism in which sun-wheels 15, 16 mesh with a planetwheel having two sets of gears 19, 20. The planet-wheel is carried by an arm 21 which is normally stationary, but which can be rotated manually to any position by a spindle 26 and gears 25, 23. The wheel 15 is attached to an arbor 14 which is rotated through gearing from a wheel 11 attached to the hour arbor 10 of the clock. The numbers of teeth on the wheels 15, 19, 20, 16 are so proportioned that the wheel 16 rotates at half the speed of the wheel 15. Wheel 16 is secured to an arbor 17 which carries a snail cam 18 through which the switch is actuated at a predetermined time. This time can be varied by altering the position of the cam by rotating the spindle 26, whereby the arm 21 and the planetwheel are rotated causing a rotation of the wheel 16 and cam 18. The position of the cam is registered by a wheel 27 meshing with wheel 23 and secured to an arbor 28 carrying a pointer which traverses the clock dial 33. A.M. and P.M. markings visible through an aperture in the clock dial are carried by a wheel meshing with a pinion 30 carried by the arbor 28. A.M. and P.M. markings are also carried by another wheel meshing with wheel 27. The cam device for actuating the switch which may control a wireless set is shown in Fig. 4. A roller 40 which engages a spring contact arm 37 of the switch as shown in Fig. 1 is carried by a pivoted lever 41 having an arm 42 whose bent-over end 43 is of sufficient width to engage a pivoted lever 45 and the edge of the cam 18. An arm 46 on lever 45 lies in the path of a pin 47 on the cam. A second arm 48 on lever 41 engages the nose 50 of a lever 51 which has a projection 52 lying in the path of a pin 53 on the cam which has a cut-away step 61. As the cam revolves the pin 47 moves the arm 46 and causes the arm 42 to engage the edge of the cam near the step 61. At the same time pin 53 moves the arm 51 to release the arm 48. Further rotation of the cam causes the arm 42 under spring pressure to drop into the step 61, whereby the roller 40 closes the switch till the pin 47 releases the lever 46 which then returns under spring pressure to its original position and strikes away the arm 42 from the cam. The arm 48 pushes the lever 51 into its initial position shown in Fig. 4. An overriding control for the switch may be provided comprising as shown in Fig. 1 a manually-operated lever 55 which may be moved to abut against the arm 48 at one point to render the switch inoperative and to the further end of the arm 48 to close the switch contacts independently of the timing mechanism.

Title: Improved piston distributor for the quantitative distribution of lubricants
Inventor: LIPINSKI JOHANN
IPC: F16N25/02
Filed: 1954-01-19
Abstract: 759,638. Lubricating. SATZGER, E. Jan. 19, 1954, No. 1558/54. Class 12 (3). [Also in Groups XVIII and XXIX] A piston distributer for liquids under pressure, e.g. lubricants, comprises two pairs of pistons 4, 5 and 6, 7 which cross one another at right angles on different planes and control the flow of liquid through outlets 23 ... 26, the pairs of pistons being connected to a link member 12 by a pin 13 and a stud 14. Each pair of pistons is made from one piece provided with reduced portions to form recesses 18. With the distributer in the position shown, liquid applied through an inlet 15 and bore 16 to a cavity 17 passes through the recess 18 and a passage 21 to a working space 10 of the piston 6. At the same time liquid in the working space 11 of the piston 7 is in communication with the outlet 23 through passage 22 and recess 18. The pistons 6, 7 are therefore moved downwardly by the liquid pressure, and due to the connecting link 12, the pistons 4, 5 commence their stroke to the right. This allows liquid from inlet 15 to reach the working space 8 of piston 4 by way of cavity 17, recess 18 and passage 19. At the same time working space 9 of piston 5 is put into communication with outlet 24, so that the pistons 4, 5 complete their movement to the right. In a similar way the pistons 6, 7 are moved upwardly and the pistons 4, 5 moved to the left, Each cycle of movement results in lubricant being discharged in succession through outlets 23 ... 26. The pin 13 is prevented from falling out by a closure screw 28. Specification 759,653 is referred to.

Abstract: 519,711. Hardness testing apparatus. LEITZ GES., E. Jan. 19, 1939; No. 1866. Convention date, April 26, 1938. [Class 106 (ii)] A hardness testing  apparatus comprises a microscope or fitting for attachment thereto combined with a member  carried by a holder so supported upon the microscope that the holder is raised clear of the support when the indentation member comes into contact with the test piece whereby the load applied to the latter is constant and produced directly by the indentation member and its holder whilst the whole device is supported by the microscope. In the embodiment shown, an indentation member 6 is mounted in a holder 7 supported by two spring strips 11, 12 and carrying two contact discs 13, 14. Normally the weight of the'holder causes the contact 14 to engage with the insulated contact 16 to light the lamp 18 or to ring a bell, but when the test piece 5 is raised, this connection is broken. If the test piece 5 is raised too far, so that the force on the member 6 exceeds the floating weight, then the contacts 14 and 16 engage to light the lamp. An additional weight 19 may be added to the holder by operation of the cranked handle 21 and the ring 20. The apparatus is mounted with an objective 3 on runners 2 beneath a microscope tube 1.
