Title: A device for the recording of the various positions of the handle of an engine-telegraph, and the periods during which the said handle remains stationary in each position
IPC: G08B9/04
Filed: 1933-06-17
Abstract: 406,180. Recording-apparatus; clockwork. FABER, J. A. C., c/o Koninklijke Paketvaart Maatschappij, Koningsplein-Oost, Batavia, Java, Dutch East Indies. June 17, 1933, No. 17340. Convention date, Aug. 27 1932. [Class 106 (iv).] In apparatus for recording the different positions of the handle of an engine-room telegraph and the periods during which it remains in each position, a point continuously records on a clock-driven strip, the movements of the handle are positively transmitted to the point and the clockwork is wound by the movement of the handle and started if it is not already running, means being provided to prevent overwinding of the clockwork. To the shaft 2 carrying the handle of the telegraph is secured an arm 4 supporting a pawl 5 engaing a ratchet wheel 9 fixed to a barrel 10 to which is secured the outer end of a clockspring 13. The inner end of the spring is attached to a sleeve 17 free on the shaft 2 and carrying an arm 18 and a disc 19. A disc 20 and a pinion 21 are spring-pressed against the disc 19 to form a friction clutch, the pinion 21 driving the roll 29, carrying the record strip, through gearing 24, 26 and clockwork escapement mechanism 32. The arm 18 lies between two projections 14 on the barrel 10. When the barrel 10 has been turned to tension the spring fully, a projection 14 engages the arm 18 to turn the sleeve 17, the disc 19 slipping past the pinion 21. If the shaft 2 remains stationary for a certain time (e.g., twenty minutes) the arm 18 overtakes a projection 14 and the clockwork is stopped. A disc 34 secured to the shaft 2 has a spiral slot 35 in which engages a pin on an arm 37 engaging a sliding block 42 carrying the recording point, which is thus moved across the paper in accordance with the movements of the shaft 2. The record strip is drawn from a roll 48 and guided by a shield 46 and rollers 47.

Title: Method and apparatus for controlling machine tools
IPC: G05B19/416
Filed: 1957-05-31
Abstract: 869,012. Electric copying-machines. GIDDINGS & LEWIS MACHINE TOOL CO. May 31, 1957 [June 5, 1956], No. 17384/57. Class 38 (6). The Specification repeats the description of the programmed control system for a milling- machine disclosed in Specification 869,013 and adds the following features:- (1) Manual speed control.-The frequency of the command clock oscillator 128, Fig. 30 (not shown), can be raised or lowered by a manual control so that the entire machinery operation will proceed at a speed higher or lower than that originally programmed. When the programmed speed is already high, or the time interval short, then the programmer can add an extra code (7th hole) to the punched tape and this controls circuits to over-ride any manual speed increase. (2) Acceleration limiting.-If there is a large change in machining speed between two adjacent blocks of the programme, the programmer uses a " P " or " M " code instead of a " + " or " - " code when defining the direction of movement on the punched tape. Additionally, a " predict " circuit 525 and Figs. 14B, 14C, 28 (none shown), is provided, which by sensing the condition of the last section of the command clock frequency divider chain 129, enables a pulse to be supplied shortly before the end of the time period which has been programmed for processing the block of distance information. The combination of a " P " or " M " code and a " predict " pulse energizes a relay which causes the frequency of the command clock oscillator 128, Fig. 30 ( not shown) to be linearly reduced to 20% of its normal value so as to progressively slow down the machining process. The transfer pulse which occurs at the end of the block cancels this circuit and the frequency rises linearly back to normal, thereby restoring the programmed machining rate. Provision is also made for the " predict " pulse to occur earlier in the time period when the manual speed control (see above) has been set to raise the machining speed. Specifications 869,014 and 869,015 also are referred to.

IPC: B60R16/00
Filed: 1918-10-28
Abstract: 134,291. Zalocostas, D. G. Oct. 28, 1918. Lighting systems. - The circuit for the taillamp of a motor-vehicle is completed by a switch arranged within the vehicle, and can only be reopened by a switch on the outside of the vehicle away from the driver's seat, thereby preventing the obscuring of the vehicle identification number when in motion. The circuit from the main battery 16 to the tail-lamp 38 may be completed by the head or side light switches 10, 11, and is retained closed by an electro-magnet 40 even if the switches 10, 11 are opened; the supply circuit (with the electro-magnet armature attracted) is through the blades 30, 32, displaced blades 43, 50, the magnet winding to the lamp. When it is desired to re-open the circuit, the blades 30, 32 are separated by the push-button 33, which, together with the electro-magnet and switch contacts, is mounted in a dust-proof box on the underside and rear of the vehicle. An auxiliary battery 35 may be used to supply the lamp, if the main battery were purposely short-circuited, a fuse 27 protecting the auxiliary battery. A pilot lamp 57 may be used to indicate whether the lamp is alight. In a modification, the pilotlamp circuit is controlled by an electro-magnet, which, should the tail-lamp contact be earthed, opens contacts in the pilot-lamp circuit, so that when the switch 56 is closed, the pilot lamp does not light. In another arrangement where no pilot circuits are used, the electro-magnet 40 and taillamp are supplied in parallel from the batteries. Instead of closing the tail-lamp circuit by means of the head &c. light switches, an independent switch may be used. In all the arrangements, a circuit having been established through the electro-magnet and lamp, the armature, on its displacement, sewitches another maintaining-circuit in place of the original circuit. The opening in the switch-box 29, Fig. 6, through which the press-button 33 is worked, is closed by an indiarubber sheet 60.
