Abstract: 681,233. Hand rails for vehicles. DAIMLERBENZ AKT.-GES. Oct. 30, 1950 [Oct. 28, 1949], No. 26396/50. Class 103 (iv). A hand rail arrangement for the interior of a motor vehicle is distinguished by a rail, preferably one on each side of the vehicle, mounted on the inside of a side wall above the window and door frames and extending, for example, following the curvature of the upper edge of the windows, from the front wall containing the wind-screen to above the back rests of the rear seats. The rail 1 is attached to a side wall 2 of the vehicle body above the window and door frames 3 and may be tubular and covered with a material to match the interior lining of the vehicle.

Title: Compactors
IPC: B30B1/18
Filed: 1973-03-14
Abstract: 1416129 Refuse compactors HOBART CORP 14 June 1974 [14 March 1973] 26577/74 Divided out of 1411289 Heading B8C The subject-matter of this Specification is substantially the same as that described in Figs. 2, 46-48 of Specification 1,411,289 but the claims are concerned with a trash compactor comprising a housing 12 with an open trash receptacle 14, a reciprocable compacting ram 18 movable into, and out of, said receptacle, a reversible electric motor 22 for driving the ram, a driving connection between said motor and said ram and yieldable means co-operating with said driving connection and arranged to permit said motor to commence rotation before the motor exerts a driving force on the ram via the driving connection. After a load is compacted in the receptacle 14 and the motor is stalled there exists a high force between the jack screws 16 and the threaded drive sockets 20 so that a substantial torque is required to rotate the motor in the reverse direction to retract the ram. The spring-loaded mechanism 44, 46, 52, which tensions the drive chain 36, allows the motor 22 to commence rotation in the opposite direction for at least a fraction, e.g. half, of a motor revolution, before a heavy load is encountered the motor first drawing against the slack in the upper chain reach 38, Fig. 2. In this manner an inexpensive motor with a relatively long life can be employed. A system for controlling the starting, stopping, and reversal of the motor is described with reference to Fig. 3, not shown.

Abstract: 968,604. Bottling. JAGENBERG-WERKE A.G. July 26, 1961 [Sept. 12, 1960], No. 27058/61. Heading B8T. A receptacle is filled with liquid, e.g. milk, by a device comprising a metering cylinder and plunger and the arrangement is such that the distance between the rising level of liquid in the receptacle and the supply aperture leading from the cylinder is maintained substantially constant during the filling process. A double filler is shown in Fig. 1 and is supplied from a vessel 4; each filler includes a hollow plunger rod 2 supplying liquid from the vessel to a metering cylinder 7 surrounding a plunger 1 which remains stationary during the dispensing operation. The cylinder, which includes a delivery pipe 8 with a feed aperture 9, is secured to a member 11 attached to a vertically reciprocable rod 12 driven by a lever and cam mechanism. The rod 12 passes through a stationary guide 22 and is attached to a holder 3 slidable on the rods 2. The plunger has an inlet valve 5, Fig. 7, and the pipe 8 an outlet valve 10. In operation, the metering cyclinder descends relative the plunger and its delivery pipe 8 enters the receptacle 20 until the aperture 9 is adjacent the receptacle bottom; during this stroke the cylinder is filled with liquid. The cylinder then rises, with the plunger stationary, whereby the liquid is delivered into the receptacle. During this stroke the aperture 9 is disposed in, or a short distance below, the plane of the liquid level in the receptacle. When the filling is complete the plunger and cylinder are raised to clear the receptacle which is replaced by an empty one. A rod 6 projecting from the vessel 4 is guided within the rod 2 and rests on the valve 5 and serves for the removal of air from the device.
