Title: Joining lead end of untreated sliver to trailing end of treated sliver - by overlapping and compressing
IPC: D01G19/14
Filed: 1975-03-20
Abstract: The trailing end of a roving which has already been treated is supported on a conveyor adjacent the rear end of which are provided a pair of fluted wheels forming a nip through which the conveyor and roving pass, the direction of rotation of the fluted wheels being reversed to move the trailing end of the roving into a suction duct beneath the fluted wheels so that the trailing end is held in the suction duct. The leading end of a roving being combed by a combing device is held in a clamp which is movable to deposit the leading end of the roving onto the trailing end of the roving and the direction of rotation of the fluted wheels is again reversed so that the trailing end of the roving moves from the suction duct and the superimposed trailing and leading ends pass through the nip of the fluted wheels and are compressed together. The device is less prone to wear than devices using a transfer bar and can be operated at higher speeds.

Title: Self cancelling control for direction indicator switch - with magnetic coils and magnetic shutter linked to discriminating circuit
IPC: B60Q1/40
Filed: 1976-05-31
Abstract: The steering wheel mounted direction indicator switch is fitted with two sets of magnetic coils (K1, K2) which monitor the field between them and a core (3) in the centre of the steering column. A shutter (14) is spaced between the coils and the core and rotates with the steering action. The coils are linked to a control circuit which monitors the relative shutter action as the switch is operated and as the wheel is turned. It cancels the flasher action when the steering is returned. The control circuit discriminates between the direction of rotation of the steering and provides a simple, non mechanical monitor for the steering. It can cater for small steering deflections such as when overtaking.

Title: Sprung roller for projection screen - has spring relaxing cap at one end to loosen tightly wound screen
IPC: G03B21/58
Filed: 1976-10-19
Abstract: The projection screen is wound on a spring loaded roller mounted inside a tubular housing with a slit through which the screen is pulled for operation. A ratchet secures the screen in the extended position, with the ratchet released by pulling on the screen so that it is wound back into the cylinder. The cylinder end opposite to the spring has a manual control cap (12) coupled to the roller by a series of holes (18) in a flange of the roller, and a spring loaded peg (14) in the cap. By twisting the cap the spring force can be loosened on the rolled up screen. The rolled screen assumes looser loops so that any reflective covering of the screen is not damaged by the close packing. The screen is subsequently pulled out with ease until the spring force is reached.
