Abstract: 1,64,230. Electric timepieces. BULOVA WATCH CO. Inc. Feb. 9, 1966 [Feb. 10, 1965], No. 5752/66. Heading G3T. In an electronic timepiece wherein a vibrating index finger 21 engages ratchet teeth on an index wheel 19 coupled to a gear train 30 - 38 having a minute wheel 38 and a seconds wheel 32 and wherein a pawl 25 engages the ratchet teeth to prevent reverse motion of the index wheel, a time setting mechanism comprises a hack lever 42 having a pin 47 to lift the pawl away from the ratchet wheel and a shoe portion 45 for engaging a brake disc 46 mounted on the seconds wheel shaft to brake the seconds wheel, and a clutch wheel 48 for engaging a setting wheel 50 meshed with the minutes wheel. When a stem 39 is pulled outwardly it releases a nose 42a of the lever 42 and a spring 44 rotates the lever so that the pin 47 lifts the pawl 25 away from the ratchet wheel 19 without disturbing the index finger 21 which thus causes the wheel 19 to oscillate. On further pulling the stem, the shoe 45 engages the brake disc 46 to stop the movement of the seconds wheel and then a setting lever 51 cams a clutch lever 49 which forces the clutch wheel 48 down into engagement with the setting wheel 50 against the action of a spring 56.

Abstract: 823,857. Springs. GENERAL ELECTRIC CO. Ltd. Feb. 18. 1957 [Feb. 27, 1956], No. 6054/56. Class 108(3) A spring for vibratory equipment comprises a plurality of elastic plates 1, having centre spacers 6 and edge spacers 4. As shown, the spacers 6 are in the form of two spaced-apart bars between which are rubber spacers 7. The spacers 4 are in the form of parallel lengths of steel disposed along two opposite edges of the plates 1 which are of rectangular or square spring steel. Rubber spacers 7<SP>1</SP> are inserted between the plates 1 adjacent the spacers 4. The spacers may be formed by suitably compressing the plates 1, or they may be welded to the plates 1. The spacers 4 may be bonded to the rubber spacers 7. The rubber spacers 7, 7<SP>1</SP> may be used to control the alignment of the steel spacers during assembly. The natural frequency of the spring may be adjusted by varying the degree of separation of each pair of spacers 6. A finer variation may be obtained by varying the compression of the spring by adjustment of screws 12. In a modification (Fig. 1, not shown) the pairs of spacers 6 are replaced by a single central spacer and the rubber spacers 7, 7<SP>1</SP> are replaced by rubber spacers at the edges which alternate with the spacers 4.

Filed: 1965-03-07
Abstract: 1,137,916. Crates. INDUSTRIAL MOULDINGS (WARWICK) Ltd. 25 Feb., 1966 [7 March, 1965], No. 6160/65. Heading B8P. The base of a rectangular bottle-crate is provided with projections defining six rectangular areas 5-10, extending below the plane of the base to facilitate stacking, the external length: width ratio A : B of the crate being between 3 : 2 and 4 : 3. The rectangular areas 5-10 are arranged in two rows of three parallel to the long axis of the crate, the separation of the two rows being between four and five times the width x of a path 12 defined around the periphery of the crate between the outer edge of the crate itself and the outer edge of the areas. The rectangular areas in each row of three are separated by between three and four times the width x. The path 12 is arranged so that when two crates are stacked directly one above the other, an upper edge (4), Fig. 1 (not shown), of the lower crate engages the base of the upper crate around the path 12, lateral movement being prevented by the projections. In the preferred embodiment the ratio B : A is 69 : 100, and the projections are themselves substantially rectangular, filling the areas 5-10. The four corner projections 5, 7, 8, 10 are square in section, having dimensions t and y both of (B31/69-2x), and the length l of the centre projections 6, 9 is 0À24A. These dimensions permit inter-bonding of superposed crates in adjacent layers, particularly in the stack configuration in which each layer is of dimensions 3A by (2A + 3B), Figs. 4, 5 (not shown), adjacent layers being arranged so that there are no vertical " cleavage planes " extending through the stack to introduce instability. The stack may be arranged on a pallet of standard size. The crate, which may be formed of injection moulded plastics material, has internal partitions (15), Fig. 1 (not shown), to retain bottles, the crate height being sufficient to ensure that the projections on an upper crate do not interfere with the bottles in a lower crate. Reinforcing struts, ribs &c. may also be provided. In an alternative form the rectangular areas 5-10 may each be defined by several projections, the essential requirement being that there is a projection touching each of the sides of each rectangle, so that correct alignment of the stacked crates is achieved.

Title: Improvements in or relating to control arrangements for rotating machinery
Inventor: GREY JOHN CONSTANTINE
IPC: F01D21/02
Filed: 1952-03-14
Abstract: 717,183. Engine stop-gear; turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Feb. 27, 1953 [March 14, 1952], No. 6663/52. Classes 110(3) and 122(4) [Also in Group XXIX] A protective control arrangement for a rotating machine comprises an overspeed trip mechanism and a device which is responsive to the oil pressure in the lubrication system supplying the machine bearings and is operable to shut down the machine in the event of the failure of the lubrication system which is pressurized by an independent auxiliary pump 29. A magnet 34 is mounted on a turbine shaft 33 of non-magnetic steel and rotates therewith between poles 35 to form an alternator whose output is led via leads 36 to a control circuit 38 incorporating a filter circuit whose output controls a solenoid 22. A butterfly valve 12 in the turbine inlet duct 10 is biased into the closed position by a spring 15 and has fixed to the outer end of its spindle 16 a plate 17 having two detents 18, 19 therein respectively co-operable with a pawl 20 on a spring- loaded lever 21 and the plunger 26 of a solenoid 27. The lever 21 may be operated to release the pawls 20 by operation of either the solenoid 22 or a solenoid 23 in series with the solenoid 27 and a pressure operated switch 24 in the circuit supplying current to the lubricating oil pump motor 30. When the turbine is at rest the valve 12 is closed, the detent 19 is engaged by the plunger 26, the pawl 20 is clear of detent 18 and all the solenoids are de-energized. To start the turbine, the lubricating oil pump motor switch 40 is closed and when sufficient oil pressure is developed to operate the switch 24, the solenoids 23 and 27 are energized thereby lowering the plunger 41 and freeing the plunger 26 from the detent 19. The valve 12 is then opened by a hand lever 14 and the pawl 20 engages the detent 18 to retain the valve in the open position. If the turbine overspeeds the solenoid 22 is energized and the plunger 42 thereof lifts the arm 21 to free the pawl 20 and the valve 12 is closed by the spring 15. If desired the circuit 38 may be arranged, under overspeed conditions, to also de-energize the solenoids 23 and 27 to prevent restarting. If the oil pressure fails the switch 24 opens and both solenoids 23, 27 are de-energized and the lever 21 is lifted by the plunger 41, the valve 12 is closed by the spring 15 and the plunger 26 engages the detent 19 to ensure that the valve cannot be reopened until the oil pressure is restored.
