Abstract: Očelem řešení je vytvoření takového
konstrukčního uspořádání palce a unášeče
odstředivého regulátoru předstihu zapalování,
umožňující zvětšení rozsahu regulace,
případně zvětšení citlivosti systému
při omezeném zástavbovém prostoru. Uvedeného
cíle je dosaženo tím způsobem, že
dosedací část palce je vytvořena rovinnou
dosedací plochou, rovnoběžnou s podélnou
osou čepu odstředivého závaží, která je
ve styku s kontaktní plochou unášeče, jež
má v příčném řezu, vedeném v rovině kolmé
na podélnou osu otáčení hřídele rozdělovače
tvar, popsaný složenou exponenciální
funkcí. Exponenciální křivku lze nahradit
množinou plynule na sebe navazujících
kruhových oblouků, přičemž odchylka od
exaktního exponenciálního tvaru je v normálném
směru ke kontaktní ploše unášeče
v absolutní hodnotě menší než 0,5 procenta
osové vzdálenosti středu hřídele rozdělovače

Patent DE-2533953-B1 (DE)
Title: Seal between two mine roof supports - has swinging angle bars attached to supports and spring biased together
Inventor: RAETZ BODO-WERNER
IPC: E21D23/03
Filed: 1975-07-30
Abstract: The sealing system between two mine roof supports (4, 4') employs two angle-shaped sealing elements (7) with an upper arm (1) towards the roof and a lower arm (2) hinged to a horizontal guide (3) in each support. The angle (9) between the two arms is an acute angle, forming a sharp contact point (8). The horizontal guide (3) has a spring (6) around it, and is attached to the middle of the lower arm by a pivot (10). Each element (7) may be swung against an opposite element by a piston and cylinder actuator (5) suitably positioned on the support (4) and attached by another pivot (12) to either the top or the lower arm. In another design, a U-shape fitting may be used to locate the bottom edge of the element instead of using a piston actuator.
Patent DE-2643169-B1 (DE)
Inventor: SAUER HELMUT DIPL-ING
IPC: H02J3/18
Filed: 1976-09-24
Abstract: The idle power of a consumer which is supplied from an alternating voltage mains is compensated using a self-commutated power converter, which is connected to the mains on the alternating voltage side, and which has controllable valves, which can be forced off, in a bridge circuit. A constant direct current (Id), which corresponds to the maximum idle power, is fed to the self-commutated power converter (5) on the DC side from a DC source (10). On the DC side, parallel to the power converter valves (A to F), is a DC converter (18), which is driven at a whole number multiple of the mains frequency. The DC converter and the power converter valves are controlled so that a current (i1, i2, i3), with its fundamental at mains frequency, and its phase position relative to the mains alternating voltage practically constant, is generated at the output of the power converter. The compensation device can react very quickly to changes of idle power. This is possible because no change to the impressed direct current (Id) supplied by the DC source (10) is required. <IMAGE>
Patent DE-2726908-B1 (DE)
Inventor: TEN EICKEN HEINZ
IPC: G07F17/10
Filed: 1977-06-15
Abstract: The coin-deposit lock equipped with a timer has a locking function that can be released by the insertion of a plurality of coins. In this function, the coins fall into the bolt (18). They release the latter, so that it advances, as a result of the actuation of blocking members. At least one coin remains in the bolt (18) as a deposit coin, until the time set on the timer has expired, in order to achieve an intermediate use. During the expiry of the time set on the timer, the deposit coin can be released so as to fall into a coin-return compartment by the operation of an actuating handle (9) of the lock formed by the coin-return knob of the lock. The actuating handle (9) for releasing the remaining coin shifts the shoulder (40) holding this coin only when the bolt (18) is retracted. The bolt (18) has a plurality of coin shafts (31, 32) located in planes parallel to one another, and a plurality of blocking members (45, 46) loaded in the bolt-releasing direction by the inserted coins. Some of these blocking members (45, 46) release the respective coin, so that it falls into a collecting compartment, during the advance of the bolt (18). At least one blocking member (46) is controlled in the advance position of the bolt. Such deposit locks are advantageously used in lockers of any kind and in cloakroom cupboards for indoor swimming pools. <IMAGE>

Abstract: A device including a cover and a shaft inserted in the thickness of the front portion of the sole, and constituting a journalled system, adapted to ensure control of the flexural rigidity of a shoe, in particular a snowboard boot, or adapted to ensure the protection of the front surface of the shoe, partially or in its entirety. All of the elements forming the system can be removable. The journal which it determines provides the cover with a front-to-rear mobility which is presented, in closed position, against the front surface of the shoe. Connected to the latter by a retaining mechanism specific to the shoe, the cover offers, due to the properties and the shaping of its constituent materials, a resistance to the crushing and flexural and torsional deformation of the shoe in its front portion during use.

Abstract: A multipurpose engineering construction machine of the loader/shovel type has a mobile chassis centrally mounting a driving and control station. The chassis supports a loader assembly at the front, and a shovel assembly at the rear. These assemblies are capable of being controlled independently of one another via a hydraulic circuit selectively feeding a number of directional control valves that can be actuated by a manipulator and that control hydraulic actuators operating components of each assembly. The direction control valves are grouped together as a single module mounted transversely on the chassis between the rear axle and a frame supporting the shovel assembly. Hydraulic fluid supply is provided via a variable-throughput pump supplying a priority valve associated with the module. Distribution of fluid to each directional control valve is performed with a compensation balance allowing the deliveries to be adjusted in stages.
