Patent LV-14466-B (LV)
Title: Electronic transmitter of codes
Inventor: KAREVS VLADIMIRS
IPC: B61L23/22
Filed: 2011-11-24
Abstract: The invention refers to the transport sector, and it can be used in railway automatic blocking systems. The invention increases the safety and stability of system and reduces the service costs. The offered transmitter contains (fig.1): the relays 1 and 2 for commutation of power lines; the control device 3; channels 4, 5 and 6 of red code (RC), yellow code (YC) and green code (GC); interface 7; relays 8 and 9 of RC channels; relays 10 and 11 of YC channels; relays 12 and 13 of GC channels. Control device 3 starts initialization of program after powering of microcontroller. If the line voltage is within range of nominal voltage, then the relays 1 and 2 are activated. Said activation powers channels 4, 5 and 6. At the same time the channels 4, 5, 6 are initialized. Channels 5 and 6 are synchronized by signal from channel 4. The output signals of channels 4, 5 and 6 are fed into the input of control device 3 where the codes are validated taking into account the numerical-code values and their compliance with accuracy criteria of time characteristics. At the same time device 3 controls the quality of supply voltage. In the case when the power supply voltage loses the quality and codes do not meet the validation criteria, then the excitation signals from relays 1 and 2 stop the operation of transmitter, and information about this is sent to the interface 7. At the end the microcontrollers of channels 4, 5 and 6 return their programs to the state of beginning, the RC 4 again resynchronizes channels 5 and 6, control device 3 continues functioning, and the interface 7 is provided with the information about the normal operation of transmitter.

Title: Protection device of induction motor using error compensation of windings temperature measurements
Inventor: ŠNĪDERS Andris
IPC: H02H7/085
Filed: 2015-07-16
Abstract: This invention relates to electrical engineering and can be used for effective protection of three phase induction motors against prolonged thermal overload of stator windings under cycled load, disrupted normal cooling conditions, frequent overloads and locked rotor conditions. The aim of the invention is to increase electric motor operation reliability by decreasing of windings failure probability to prevent the possibility of thermal overload of the windings insulation under extreme mechanical and electrical overload conditions by directly measuring of the stator windings temperature with preemptive compensation of the temperature sensors error due to thermal inertia at high temperature rise speed. The proposed temperature protection device (Fig.1) is characterized in that the temperature of the induction motor (1) stator end windings is monitored by three temperature sensors (2, 3, 4) connected in series, whose resistance change in dependence on temperature is converted into voltage Ua by an adapter (5), which is simultaneously transmitted to the differentiation filter circuit (6) with an amplifier (61) and differentiation filter (62), as well as directly to one of the adder (7) inputs. An output signal of the differential filter circuit (6), as a compensation voltage delta-Uk of the dynamic error of temperature measurement, is transmitted to the second input of the adder (7). If the windings temperature rises to critical value, the adder output voltage reaches a tripping voltage of the solid state relay (8) Ur, a commutation device (9) switches off electrical contacts (10) and disconnects an induction motor (1) from the electric network, preventing thermal overload of the windings. Operation effectiveness of the differentiation filter circuit (6) is confirmed by simulation results of the stator windings temperature measurement error (Fig.2).

Abstract: A single mixing valve has a ball-like valve plug with hot and cold water inlet ports and outlet ports and a valve housing having a valve seat face of the same form as the plug. The housing has inlet ducts for the hot and cold water to be mixed and an outlet duct for the mixed water, the ducts porting into the face. A driving part is joined with the plug and is able to be rocked therewith for changing the rate of outlet of water from the valve and to be moved for changing the mixing ratio of the hot and cold water. The driving part is limited in its rocking motion to motion about a rocking axis running through a middle point of the plug and is limited to turning about an axis of turning running through the middle point. The valve has a guide plate, which may be turned in a plane parallel to the rocking axis of the driving part, with same in relation to the housing. The plate has a slot in which the driving part is keyed while being able to be moved along the slot. With this system it is not possible for the plug to be moved into skew positions.

Date Apr. 21, 1988.The freewheel drive has an outer ring member which is integrally united with a sleeve for reception of the starter shaft, by way of a flange. This one-piece part forms a housing for the reception of the inner ring member, which is integrally connected with the driving pinion by way of a radially projecting flange. This integrally fabricated part has cam tracks extending eccentrically of the axis, on the outer peripheral surface of the inner ring member. Roller bodies under the bias of strap springs bear against the cam tracks and against the circular inner peripheral surface of the outer ring member. Each strap spring is held in a respective spring receptor of a ring-shaped spring guide. The latter is non-rotatably held against the inner ring member and bears against the flange. The advantage consists in the more economic manufacture of the inner ring member which has the cam tracks, and in the reliable functioning of the freewheel drive even under the most extreme loads.

Abstract: A self-loading firearm for firing rubber bullets and the like has an actuating mechanism comprising a toggle linkage (13, 17) which is straightened on operation of the trigger (6) against its spring bias. Initial straightening of the toggle linkage (13, 17) moves the breech block (15) forward to locate a round of ammunition in a short socket (83) at the chamber end of the barrel (1). As the toggle linkage (13, 17) moves over centre it locks the breech block (15) forward and displaces a sear (29) to release the firing pin (20). The round is fired with its case virtually unsupported. On release of the trigger (6) the toggle mechanism (13, 14, 16, 17, 18) is bent so withdrawing the breech block (15) and the spent round which is automatically ejected. The firing pin (20) is simultaneously re-cocked. Rotary (2) and vertical stacking rechargeable magazines are described, from which a fresh round is automatically fed to the breech on ejection of a spent round.
