Title: Automatic locking device for safety belts
IPC: B60R22/38
Filed: 1969-10-28
Abstract: In an automatic inertial locking device 2 for a vehicle safety belt 3 comprising a rotatable shaft 5, mounted in a casing 1, for reeling the belt, and a rotor 10 fixed to the shaft on whose circumference at least one locking pawl 12 is disposed to be radially outwardly displaceable, in response to guided centrifugal forces to cooperate with at least one locking tooth 13 in the casing, a disc member 21, which is coaxial and rotatable relative to said rotor, rotates at the same speed as the rotor below a set value of angular acceleration and, by means of position guide members on the disc, prevents the pawl 12 from locking with one of the teeth 13, but when the angular acceleration of the rotor exceeds the set value, said disc, due to inertial forces, rotates momentarily more slowly than the rotor and causes said guide members to release the pawl to lock with the tooth. The safety belt is held on the shaft by a coil spring 4, and its internal anchored end by a rod 7. The pawl is in two halves - a locking portion 17 to engage the tooth, and a guide portion 18 to engage with the guide member, as in Fig. 7. A pin 41 projects from the disc member into a groove 39 in the rotor as in Fig. 4, the pin being held in position by a spring 40 at one end of the groove. Above the set rotor acceleration the pin will displace as shown and hence the disc will lay the rotor and the device will lock. The critical acceleration can be varied by altering the spring strength. A locking member 25 (not shown), formed as a two armed lever is positioned such that it engages the tooth and locks the device when the device is axially or laterally accelerated. The locking pawl may be housed in a wedge shaped recess in the rotor and thus swingable or it may be only radially displaceable in which case the position guide member is formed as a stop 47.

Title: Color improvement of high pressure sodium vapor lamps by pulsed operation
IPC: H01J61/88
Filed: 1977-01-15
Abstract: High pressure sodium vapor lamps containing sodium or both sodium and mercury are raised in color temperature and improved in color rendition by pulse operation.

Title: Acoustic wave devices
IPC: H03H9/02
Filed: 1979-09-20
Abstract: In an acoustic wave device having a pair of spaced apart reflectors forming a resonant cavity, each reflector consists of an array of parallel reflective elements. At least one of the reflectors is weighted not by simple withdrawal of reflecting elements from a nominal uniform array but instead by substituting reflective elements of the uniform array with elements providing both net-zero reflection at required positions and also at least partial compensation for the velocity perturbation which would be produced by such simple withdrawal. Such weighting may be used to suppress the side lobes of the reflector response and hence improve the stopband performance of the acoustic wave device and, for example, a coupled resonator filter in which that device is incorporated.

Abstract: In order to improve the separating result in horizontal separators and in particular in order to achieve a high degree of selectivity with large processing loads and a small separation path, in a process for separating heterogeneous material, in particular for presorting refuse, which has been precleaned of fine materials, in a gas stream which is directed essentially horizontally, into which gas stream the material is dropped from above, the individual material components - depending on their weight and size - describe different flight paths and are separated in this way, it is proposed that the material components entering the gas stream (separation zone 3) from above have reached at least half the value of the free falling speed corresponding to their size and density. This method can be used in a device of the type of a horizontal cross-current separator having an essentially horizontally arranged housing (19) at whose one end an inlet opening for the separating gas stream which is generated by a blower (1) and enters essentially horizontally is mounted and which housing also has in the upper region a filling opening (25) for the material to be separated and which has in the lower region a plurality of discharge openings (26, 28), arranged behind one another in the direction of the separating gas stream and downstream of the filling opening (25), for the individual material components which are deflected different distances, a fall shaft (21) being present above the filling opening (25), which shaft is of such a length that the material components have reached a speed as given above when passing through the filling opening (25) or that instead of the fall shaft (21) a relatively short input shaft (20) is provided into which an acceleration device for the material components, e.g. a cellular wheel sluice (23) is installed.
