Title: Actuators which respond to acceleration
IPC: B60Q1/44
Filed: 1977-04-20
Abstract: 1537416 Seat belts and deceleration forces FORENADE FABRIKSVERKEN 20 April 1977 [26 April 1976] 16393/77 Heading A3V A vehicle deceleration sensing device has a body 3 which is displaceable by deceleration from the position shown in Fig. 1 in which the body 3 is restrained by an inner portion 8a of an annular spring 8 which has an outwardly extending flange 8b which is deflectable axially of the spring 8 to effect radial flexure of the spring 8 and release of the body 4 for displacement; and another body 6 which is displaceable by deceleration from the setting shown in Fig. 1 to that shown in Fig. 2, the body 6 being disposed to cause deflection of the flange 8b on the occurrence of a substantial movement of the body 6 from its position of repose. When deceleration forces of a predetermined magnitude occur, the body 6 will move downwards. If, however, the deceleration forces are of short duration, the body 6 will not have time to move downwards far enough to engage the flange 8b of the spring 8. Thus, when the deceleration forces cease, the spring 7 will return the body 6 to the position shown in Fig. 1 without disturbance of the spring. Upon prolonged deceleration of a certain magnitude, however, the body 6 will have time to move downwards, corresponding to the distance d, until a shoulder 11 of a recess 10 pushes the flange 8b downwards, thereby causing flexure of the spring into its second position as shown in Fig. 2, in which the inner portion 8a of the spring releases the body 3. If deceleration continues after this, the body 3 moves in the deceleration direction 12 against the action of a spring 5. The consequent movement of the body 3 can be used to cause tightening of a seat belt or belts of a safety harness.

Class 116 '[Also in Group XXX] In a conveying system for conveying meals from a kitchen to a selected position in a restaurant, means are provided for deflecting a meal from a conveyer of the system, without arresting its motion, to direct it to its selected position. The apparatus consists of three superposed conveyers. The top one consists of a moving pair of parallel bands 11 for taking empty trays with orders from each serving position to the kitchen, and the bottom conveyer is also a pair of bands 37 for conveying used crockery in containers to the kitchen. The middle conveyer is for serving meals and consists of three pairs of endless bands 18, 19 and 20, belts 18 being disposed in the kitchen and driven at a slow speed, belts 19 being periodically accelerated from said slow speed to a fast speed by means of chain gearing in which one of the chain wheels is eccentrically mounted, and belts 20,'which are made to travel on edge by means of guides 21, being driven at said fast speed. A gate, not shown, is provided at the junction of bands 18 and 19 to hold up trays and release them when band 19 is travelling at slow speed. Upon arrival at a serving station, only the last of which is shown, the trays pass a switch 28 having a characteristic finger or fingers 29 which are engaged by a tray having strips 14, Fig. 3, in corresponding positions, the trays being set in the kitchen. Upon actuation of switch 28 at the selected station a solenoid is energized which opens a valve admitting fluid to a cylinder 25 which through a crank 26 and shaft 27 moves a deflecting bar 24 across the path of the tray as shown in chain lines, Fig. 2A, so that the tray is deflected on to skids 30 and thence to a pair of slow-moving bands 31 which deliver it to a table 32. On arrival a switch 33 is depressed which actuates a visual indicator. During passage of the tray from the bands 20 a switch 34 is depressed which returns the bar 24 to normal position. If trays accumulate at the serving station further switches 35 are depressed which cut out operation of bar 24 if the station is full, so that the trays which have been diverted to this station pass to the end of bands 20 where they press a switch 36 operating an indicator. The apparatus is enclosed except for openings at the serving station tables by a casing 38. Openings are also provided for insertion of the empty trays with orders on to bands 11 and of the used crockery containers on to bands 37. Controlled gates are preferably used for feeding the returned trays and crockery on to the bands 11 and 37 so as to prevent collisions.
