Title: Improvements in or relating to arrangements for varying the work feed velocity in machines
IPC: F16D31/08
Filed: 1947-01-24
Abstract: 644,995. Variable-speed epicyclic gearing AKTIESELSKABET MYRENS VERKSTED. Jan. 24, 1947, No. 2258. Convention date, Jan. 19, 1946. [Class 80(ii)] [Also in Group XXIII] An arrangement for varying the work. feed velocity in machines is characterized in that the working member (e.g. a saw) is. driven by a pulley 4 which is adapted by overcoming a preferably adjustable spring 6 to change its angular position relative to a driving shaft 1 on which is also loosely mounted a pulley 10 for the work feed movement, the two pulleys being interconnected through a gear pump 13 located in the pulley for the working member the outlet of which pump in the normal position. of the pulley is kept closed by a valve 14 so that the pulleys are rigidly connected, but which valve is opened when the pulley for the working member at a predetermined load changes its angular position relative to the shaft so permitting relative angular movement between the pulleys and a corresponding reduction in the work feed velocity. As described, 1 is the driving shaft of e.g. a circular saw, to which is keyed a sleeve 2 having spiders 3 two of which are connected by springs 6 having adjustable bolts 9 to the pulley 4 which is loosely mounted on the sleeve 2  and driven by a suitable source of power. The pulley 10, also loosely mounted on the sleeve 2, projects into the hollow portion 5 of the pulley 4 and has a toothed wheel 11 engaging a pinnion 12 on the driving shaft of the gear pump 13 the intake of which is in open connection with the interior space 5, the latter being filled with oil &c. The outlet of the pump is also in connection with the said space through a conduit nor-- mally closed by the rotatable valve 14 to block the gear pump which thus acts as a fixed coupling between the pulleys. When the pulley 4 rotates clockwise (Fig. 1) with respect to the shaft 1 due to increased resistance at the working member, it compresses the springs 6, the valve 14 is opened by the link 15 connecting an eccentric 16 on the valve with a spider 3, and the pump outlet conduit is partially opened. The driving shaft of the pump and its gear 12 will then rotate thus reducing the revolutions of pulley 10 with respect to pulley 4. As a safety device the outlet conduit from the pump may have a spring- loaded safety valve 17 of known type.

Title: Improvements relating to balanced oscillatory drive means
IPC: A01D34/30
Filed: 1954-01-26
Abstract: 772,472. Mowing machines. UTAH SCIENTIFIC RESEARCH FOUNDATION. Jan. 26, 1954 [Jan. 28, 1953], No. 2274/54. Class 6(3). [Also in Group XXIV]  A balanced drive mechanism for an oscillating device is shown applied to a tractordriven mower wherein a reciprocating knife 14, Fig. 4, is linked to an oscillating driving arm 72 which is pivoted on a fixed shaft 76, and the shaft 76 also supports a U-shaped pivoted counterbalance 88 straddling the arm 72, the arm and the counterbalance being oscillated in antiphase by respective connecting rods 68, 66 on opposed cranks of a shaft belt-driven from a power take-off shaft 40, Fig. 1. The counterbalance 88, Fig. 5, comprises two legs interconnected by a tie 94, and may have additional masses attached thereto. The counterbalance may be arranged so that its centre of gravity lies in the plane of oscillation of the arm 72 to to minimize transverse stresses, but in the construction shown the centre of gravity is displaced from the said plane as a compromise to avoid excessive loading on its bearing 96. In a modification the one-piece counterbalance is replaced by two equal counterbalances suspended either side of a driving arm and separately driven in antiphase thereto by the outer cranks on a three-crank shaft. It is stated that counterbalances and driving arms may be suspended from separate axes, and that the axes may be below the effective masses. The knife 14 is linked to the arm 72 by a leaf spring 82, a single pivoted joint 81, and a tapered socket connection 79 as described in Specification 772,471. The crankshaft has keyed thereon a combined pulley and flywheel 46 and is mounted in a housing 28 which is pivoted on a bifurcated radius bar 32 and has a lug 38 for the attachment of manually or power operated mechanism (not described) for raising and lowering the mower bar assembly to cut on banks or in depressions. Since the housing 28 is pivoted on the crank shaft axis, the said raising and lowering does not affect the relative positions of the knife blades 16 and the non-reciprocating ledger plates 20 with which they coact. As a result, the required knife stroke is reduced compared with machines involving a change in said relative positions as raising or lowering is effected. The ledger plates 20 are secured to U-shaped guards 22.

[Also in Divisions H3-H5] Hot-dip galvanization apparatus comprises a ceramic or ceramic-lined container 30 with a susceptor ring 17 of low-carbon, silicon-free steel heated by a surrounding induction coil 14 to melt the zinc by conduction. Ring 17 and coil 14 are in segments or may be integral, Figs. 1, 2 (not shown). The wear of the ceramic container lining is watched by the measurement of resistance or voltage between the steel ring and a wire network 11, Fig. 2 (not shown), insulated from the induction coil. The ring segments 17 are replaceable using special grippers without pumping out the molten zinc. Firebricks 16 provide a shoulder 33 for the susceptor rings 17 so that the lower part of the furnace is unheated. The space 15 between the concrete segments carrying the induction coils 14 and the firebricks 16 is filled with a ceramic composition resistant to molten zinc. More ceramic composition 13 is provided between coils 14 and the concrete jacket 12, which provides a shoulder 22 for the coil segments.

Title: Microwave transmission line phase shifter
Inventor: DUKES JOHN MARCUS CUTHBERT
IPC: H01P1/18
Filed: 1955-01-26
Abstract: 767,067. Phase-adjustment of strip transmission lines. STANDARD TELEPHONES & CABLES, Ltd. Jan. 26, 1955, No. 2349/55. Class 40 (8). The electrical length of a strip transmission line is adjusted by inserting in the electromagnetic field a variable volume of dielectric material. The transmission line is of the type comprising a metallic strip conductor 1 separated from a ground plane conductor 2 by means of a dielectric layer 3 a small fraction of a quarterwavelength thick. To effect the desired adjustment a triangular dielectric slab 4 is inserted a variable amount into a gap in the dielectric layer 3. The slab 4 and the edges of the gap may be bevelled as shown, or, in a modification, the bevels may be complementary so that the slab 4 fills the gap completely when fully inserted. The slab 4 may have a higher dielectric constant than the layer 3. Alternative arrangements are described (Fig. 7, not shown) in which the dielectric layer 3 is continuous and the dielectric slab is inserted into the electromagnetic field adjacent the strip conductor 1 on the face remote from the ground conductor 2. The dielectric slab may have a variety of shapes and may be mounted on a pivot so that it may be rotated to and from its operative position. Several dielectric slabs may be ganged together by a mechanical linkage (Figs. 16, 17, not shown) which enables them to be moved through relatively different distances by a common actuating member. In the modification of Fig. 14, the electrical lengths of lines 18-22 are varied by different amounts upon displacement of the bevelled dielectric member 23. Where several lines 24-31, Fig. 15, form a junction the electrical lengths of the lines are varied by different amounts by rotating the bevelled dielectric member 32 about its pivot 33. In the construction shown in Fig. 12 a rat-race formed of strip transmission lines 9-12 is tuned to a desired centre frequency by means of a circular, bevelled dielectric member 4 which is movable towards and away from the transmission lines 9-12 upon a spigot 13. The invention may be applied to strip transmission lines of the type in which spaced ground conductors are provided on either side of the strip conductor.

Title: Improvements relating to pull-out type hand brakes with compressed air assistance
IPC: B60T7/10
Filed: 1967-01-17
Abstract: 1,133,924. Servo-assisted hand brakes. DAIMLER-BENZ A.G. 17 Jan., 1967 [18 Jan., 1966], No. 2388/67. Headings F2E and F2F. In a servo-assisted pull-out type hand brake, compressed air assistance is controlled by a pivoted handle 7 which is adapted to open an admission valve 20 and close an outlet valve 19 to admit air from a compressed air source via an air supply pipe 16 and a second admission valve 17 to act on a telescopic assembly within the casing tube 1 of the hand brake assembly. In the inoperative position of the brake, as shown in the Figure, a leaf spring 18 is secured on the free end of a tube 3 and presses the second admission valve 17 into its closed position to prevent compressed air from the air supply pipe 16 from actuating the brake. If the handle lever 7 is pulled in the direction of the arrow 25 by a force which is small enough not to rock the hand lever 7, the leaf spring 18 lifts and lets the valve 17 off its seat to permit compressed air to pass into the space 26 between telescopic tubes 11 and 14 and then into the space between the tubes 11 and 13. At the other upper end of the tube 13 the compressed air flows into a bore 27 closed by the admission valve 20. When the manual force on the hand lever 7 is sufficiently great to rock the hand lever in the direction of the arrow 28 about a mounting bolt 5 the admission valve 20 is opened and the outlet valve 19 is closed to permit compressed air to pass out of the bore 27 into the valve space into the space between the tubes 3 and 14 to create a force assisting the manual force by means of the compressed air pressing against the valve head 4. The hand brake assembly is mechanically locked by means of detent springs 24 engaging notches 23 disposed in the interior of the casing tube 1.
