Patent DE-2243435-A1 (DE)
Title: Rotary kiln with uniform gas space - inserted baffle wall at entrance and exit of kiln ensures uniform bed of solids and prevents removal of fines
Inventor: SPEETZEN ECKHARD DR
IPC: F27B7/24
Filed: 1972-09-04
Abstract: Uniformity of gas flow along a rotary kiln is ensured by introducing a baffle wall at each end with the same profile as the bed of solids in the rotating kiln. This profile is normally kidney shaped and at the inlet end this is used to ensure that fresh material enters at the lower aend of the kidney where mixing is most inense. At the outlet end the lower edge is made horizontal so that material leaving spills over the upper edge. These profiles ensure that gas velocities at either end are no higher than in the body of the kiln and therefore excessive entrainment of fine materila is avoided. Kiln is esp. used for treating lime or cement.

Title: Door lock with decorative housing and actuating handle - has latch actuated by handle via rectangular bar with latch and bolt locked independently
Inventor: TRANBERG ERIK RUDOLF
IPC: E05B59/00
Filed: 1973-10-08
Abstract: The lock housing accommodates two separate locking mechanisms and a greater degree of security is achieved on using this lock. If used for hotel rooms the management can have keys for operating the bolting elements of all locks in the hotel. The guest can lock the door so that no one can enter the room. In one version two decorative housings are arranged on each side of the door and the one on the inner side contains a coupling mechanism for both locking mechanisms. This coupling mechanism is operated by the handle so that on rotating the handle one lock is released first and the latch is released later. A square peg connected to the handle is used to actuate a wedge shaped latch. The locking wedge acts on a locking hook by means of a lever. When the door is closed the locking link is pushed inwards and hence the latch is locked. This latch cannot be retracted into the housing if for instance it is tampered with by a tool. The movements are transmitted by a lever.

Linkage elements are connected to the outputs of the shift register. If a specific type of pulse pattern is across the input of the shift register, a series counter is adjusted, and in case of another type of pulse pattern, the counter is again reset. The linkage elements across the output of the counter are arranged, so that after a specific number of pulse patterns, the delay is terminated. At a cut-in delay, the pulse pattern on the line triggers the resetting of the counter.
Patent DE-2403126-A1 (DE)
Title: Electric power recovery from electromagnetic machines - uses conversion of tower stored in magnetic cct. into-electric current
Inventor: VOGEL ERICH
IPC: H02K29/06
Filed: 1974-01-23
Abstract: Electric power is recovered from electromagnetic machines, in which otherwise the power stored after disconnection of the excitation current would be lost. After the excitation current has been disconnected the power stored in the magnetic circuit is converted into an electric current which is tapped off. This conversion is attained by additional coil coupled to the magnetic circuit. After disconnection of the excitation current a voltage is induced in the additional coils which form part of a secondary circuit, containing loads or stores. Preferably the system is applied to a reluctance machine with salient poles which have in operation magnetically saturated paths. In such instance the additional coil(s) is mounted in the stator.

Title: Leakage current sensitive circuit breaker - protecting against earth fault and excessive neutral conductor voltage has tripping relay
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: H02H3/33
Filed: 1974-03-25
Abstract: The guard conductor connected to the appliance case is coupled to earth through a separate circuit and also to the neutral lead via a resistor. The connection to the neutral is made after the circuit breaker neutral contact but before the summing current transformer. The value of the series resistor is selected such that in the event of an earth short circuit, for example by human contact, the circuit breaker is tripped, and tht an excessive potential difference between neutral and earth also causes a trip. The latter may be instantaneous or time delayed, for example by temperature sensitive resistor.

Patent DE-2417103-A1 (DE)
Title: Tyre tread reinforcement cord of helical filaments - is surrounded by larger helical cord to limit longitudinal stretch
Inventor: TIEMANN REINHARD DIPL ING
IPC: B60C9/00
Filed: 1974-04-08
Abstract: A stretchable, filament-like reinforcement, esp. for the tread region of pneumatic tyre blanks which are assembled flat and then moulded and vulcanised to the final tyre shape, comprises a number of helical filaments surrounded by a second set of helical filaments, so arranged that when the two sets of filaments are stretched, the outer set reduces in dia. more rapidly than the inner set. Pref., this is achieved by having a steeper pitch to the outer set than the pitch of the inner set. As longitudinal extension of the two sets of filaments takes place during the moulding of the tyre, the resistance applied longitudinally to the stretch by the outer set, having the flatter pitch, is considerably greater, so that the final result is a virtually non-stretch tread reinforcement.

Title: Exhaust gas purifier - with catalytic coating on spiral fins inside heat-insulated exhaust gas manifold
Inventor: MAURER HELMUT
IPC: F01N3/28
Filed: 1974-07-30
Abstract: The exhaust gases of an internal combustion engine are purified and detoxified by passing them through an exhaust manifold which is flanged to the engine block and acts as a catalytic reactor. The manifold consists of thin heat-resistant, but badly conducting material and is insulated by lagging on the outside; on the inside, a catalytic lining is applied to fins or wires in a spiral pattern to induce a swirling motion of the exhaust gases. This is a very inexpensive method of achieving the desired reactions of oxidn. with a minimum of expenditure. The swirling flow improves mixing and smoothens out pulsations in the flow.
