[Class 44] A slider is made from metallic, or non-metallic, material, and formed with a pull - attaching member 2 which is secured to a base 1 by its ends 17, 18, without the use of supplementary fastening members. The upper surface of the slider may be covered by a cap which may be of coloured aluminium. The fastening elements may be coloured by anodic oxidation. A slider-locking spring 3 and a pull member 4, are placed in position before the pullattaching member 2 is attached by means of the ends 17, 18, which enter sockets in the base 1. A projection 161, originally turned upwards, is pressed down into the notch of the nose 21, to permanently secure the member 2 to the base. The prong 24, of the spring 3, engages the fastener elements until lifted when the member 4 is pulled. The parts 1, 2, may be welded together at the top, and the projection 161 dispensed with. The pull member 4 may be made of thermoplastic material 26 around a metal core 25. A number of examples of sliders, based on the above, are illustrated in the specification. In one example, the locking prong is attached to the pull member, and a cavity is formed in the member 2 so that the prong can sweep inwards when the pull member is lifted upwards. In a further example the member 2 is formed as a pin at the upper end. This is inserted into a hole in the base 1, and the pin riveted over. A further modification shows a part of the cap bent up to act as a support for the member 2, and also act as an abutment for the locking spring.

Title: Automatic frequency control system
IPC: H03L7/18
Filed: 1967-01-20
Abstract: 1,109,559. Automatic frequency control systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 20 Jan., 1967 [21 Jan., 1966], No. 3135/67. Heading H3A. In an A.F.C. system where the frequency and phase of an oscillator 1 are controlled by the output of a phase discriminator 5, the latter output is fed through a low-pass filter 6 to a terminal B controlling the oscillator and is also fed via a band-pass filter 7, Schmitt trigger 8 and differentiating circuit 9 to a digital counter 10 which produces an analogue output signal which is fed to a terminal A controlling the oscillator frequency. Initially there is no input to terminals A and B which may control varactor diodes, the oscillator 1 is tuned too low, and the output of discriminator 5 alternates at a beat frequency, thereby stepping on the counter 10 until the frequency is nearly correct. An output of the differentiating circuit 9 feeds a monostable circuit 11 which disables the second input at B when triggered; when the beat frequency is sufficiently low, the monostable circuit 11 times out and allows the output of the filter 6 to control the frequency and phase of the oscillator. The actual oscillator frequency is determined by the manual setting of a variable divider 3 which reduces the oscillator frequency to that of a reference frequency F N  forming a second input to the discriminator 5.

Title: Improvements in or relating to an automatic record changing device
IPC: G11B17/16
Filed: 1958-01-30
Abstract: 862,010. Automatic gramophones. SOFRANIC. Jan. 30, 1958 [Jan. 31, 1957], No. 3204/58. Class 40 (2). In a record changer the pick-up arm 34 is mounted for limited up and down movement on its supporting shaft 36 which is also mounted for limited tilting movement about horizontal pivots 41, 42 and associated with members producing this movement to cause lifting and swinging the pick-up arm, releasing a record from a stack on a stepped centre post 22 and placing the pick-up on the record. The embodiment is described with reference to apparatus for accommodating 45 r.p.m. records with large centre holes. The turntable is driven by a tyred pulley mounted on a motor shaft 64 and engaging the underside of the turntable 9. Figs. 1 and 4 illustrate the normal position, i.e. with the automatic control disengaged and a record being played. When the pick-up reaches a predetermined position at the end of the record, a toothed member 49 on the shaft 36 arrives at a position allowing a cup-shaped cam 55, having gear teeth on its periphery, to descend so that the teeth engage a pinion 67 on the end of motor shaft 68 to rotate the cam 55 and tilt the shaft 36 to lift the pick-up from the record. Further rotation of cam 55 causes an abutment therein to engage a leaf spring ramp 65 on the shaft 36 to swing the pick-up outwardly until it reaches the position shown at 33d in Fig. 4. At this point an external abutment 60 on the cam 55 engages the end of a lever 30 to move a shoe 25, Fig. 1, which unseats a record from the stepped centre post on to the turntable. As pinion 67 finally runs into the sloping part 59, Fig. 4, of the cam 55, the pickup slides down the ramp 71 of support 69 on to the record. At this moment the pinion 67 reaches the position shown in Fig. 4 out of engagement with the cam 33 ready for the next automatic cycle. The apparatus is not confined to records of the one size described, and means may be provided for manually setting the position of the ramp and support post 69 and the release shoe 25.

Abstract: 265,377. Barker, T. Feb. 4, 1926. Relling-machines; dough working. - Dough in ribbon form, is fed to a screw-like member supported at one end and free at the other co-operating with moving surfaces in such a manner that the dough is forced into the coils of the screw and worked, the worked portion being automatically worked off the screw. The screw may comprise a corkscrew-like member a, Fig. 3, and may be of uniform or non-uniform pitch and diameter. Fig. 6 shows a machine wherein the dough portions pass through sheeting-rolls e on to a band b which conveys them beneath a flattening-roll g to a drum c which lifts the end of the dough and forces it into engagement with the screw a. A pressure roll d, pivoting in arms d<1> about the roll c and driven in the same direction, forces the dough into engagement with the screw and, in association with the drum c, causes the worked dough to unscrew from the member a. The worked dough portion falls on to a band f disposed laterally of the band b and is carried thereon beneath a shaping-band h. To facilitate disengagement of the dough from the screw, the latter may be given a longitudinal, lateral or gyratory movement. The screw may be rotated at a speed higher or lower than that of the members c; or the parts may be moved at the same speed during working of the dough and then at different speeds to effect its disengagement. According to the Provisional Specification, the screw may co-operate with a semi-circular moulding channel.
