Title: Typewriters and like book-keeping machines which simultaneously record on a signal carrier
Filed: 1956-10-24
Abstract: 851,120. Typewriters. SIEMAG FEINMECHANISCHE WERKE G.m.b.H. Oct. 24, 1956 [Oct. 24, 1955], No. 32356/56. Class 100(4) A typewriter or like machine simultaneously operates a coupled data recording device, e.g. a tape perforator, or a magnetic tape recorder, which is controlled by slides selectively positioned on the paper carriage of the machine; these slides operate contacts and energize relays in particular combinations so that at particular carriage positions of the typewriter a record is made so that when that record is next used to operate the typewriter different letter or line spacing, carriage return movements occur. The document shown in Fig. 1 is one that has been typed in the typewriter during an initial typing and that in Fig. 2 is one that has been typed as a result of the sensing of the tape made by the coupled tape perforator &c. When the platen carriage reaches a particular letter-space position e.g. the end of the wording of column 1, Fig. 1, a particular combination of four electrical contacts is closed which makes an entry in the perforated tape so that when a tape is read the next matter to be printed e.g. PART NO is printed in a different position. The additional entries in the tape make the necessary linespacing and letter-spacing movement of the machine which carries out the subsequent printing. The contacts selected may be predetermined by exchangeable slides.

Patent GB-326446-A (GB)
Abstract: 326,446. Black, H. D. Dec. 3, 1928. Totalizators.-A ticket printing and issuing machine is furnished with remote control whereby the machine can be locked against the issue of tickets, and a variable type member can be locked against alteration at the will of the operator at the remote control. A ticket printing and issuing machine is operated by depression of one of the pivoted levers 1 fitted with a ball crowding lock 15. The variable type wheel 5 is secured to a spindle 6 revolubly carried in bearings mounted upon the printing cylinder 3, and can be rotated by keying to it the spindle 12 which is provided with a knob 14. A solenoid 16 actuates a spring blade 26 which engages with a double arm lever 27 pivoted at 28, one end of which is provided with an extension 30 which on actuation of the solenoid 16 one way will move to fill up the free space in the row of balls 15 thus preventing depression of a lever, and the other end of which is pivotally connected to a rod 31 which is pivotally connected to a double arm lever 32, pivoted at 33, the free end of which constitutes a catch 34 which engages with a groove 35 in the spindle 12 on actuation of the solenoid the other way, thus preventing rotation of the type wheel. When the extension 30 is in engagement with the row of balls the catch 34 is out of engagement with the groove 35 and vice versa. In a modification shown in Figs. 6, 7 and 8, actuation of the spring blade 26 by the solenoid 16 one way moves a rod 39 and causes a pin 42, which passes through an eye in the rod 39, to engage a slot 42<1> of a stirrup shaped member 45 pivotally mounted on a rod 46 carried by frame of machine and move the member to a position above the universal clutch bar 47 thus preventing an extension 66 of a depressed lever 1 lifting the clutch bar clear of the stop 67 to start operation of the machine. During this movement of the rod 39 the stop member 43 which carries the pin 42 is moved clear of the pin 48 carried by a spindle 49 which can then be turned by the knob 50 to rotate via the bevel wheels 51, 52 the spindle 53 each complete rotation of which causes the type wheel 5 to move an amount corresponding to one type face thereof by means of the pin 54 on the spindle 53 engaging teeth of the detent wheel 7 secured to the type wheel. Actuation of the solenoid the other way causes the stop member 43 to take up a position to prevent rotation of the pin 48 and thus of the type wheel 5 and a weight 72 carried by the member 45 moves that member clear of the clutch bar 47 thus allowing the clutch bar to be lifted clear of the stops 67 by depression of a lever and the machine to be operated. Where a series of machines is employed the circuits of the solenoids thereof may be connected in parallel to one control switch. Specification 325,873, [ Class 106 (iii), Fares &c.], is referred to.

Title: Improvements in and relating to magazines for safety razor blades
IPC: B65D83/10
Filed: 1946-11-07
Abstract: 647,883. Magazines for razor blades. GILLETTE SAFETY RAZOR CO. Nov. 7, 1946, No. 33144. Convention date, Nov. 15, 1945. [Class 18] A blade magazine comprises a shell 30 having an exit 29 for the blades, an arm 35 for locating the magazine on the razor and a feed slide 46 which inserts new blades into the razor and withdraws the old blades, the cutting edges of both blades being shielded during insertion and withdrawal by the feed slide. The stack of blades is located in a drawer 38 by a member 45. The filled drawer is contained in the shell 30 and a leaf spring 37 secured to the shell projects through apertures 39 in the base of the drawer, forcing the blades upwardly. The feed slide 46 which has a slight transverse curvature, has a thumb piece 57 sliding in a lot 34 between depressed shoulder portions of the shell top. The arm 35 is inserted in a slot in the razor and the slide 46 advanced, its forward end 47 being urged upward by a slope 17 on the razor seat. The rear end of the topmost new blade 10 is engaged and advanced by slots 52, 53 on the slide 46 and inturned flanges 48, 49 on the slide engage the old blade 10<1>, lifted off its seat by the end 47. The flanges 48, 49 are flared at the forward end and grip the old blade 10<1> as the feed slide advances, the blade 10<1> being bowed over a raised portion 56. As the flanges 48, 49 clear the shell top they spring upward to abut against its forward end thus preventing withdrawal of the feed slide 46 while the magazine is attached to the razor. The new blade 10 is engaged by projections 20 on the razor seat and held while the magazine is withdrawn with the old blade 10<1> held in the slide. Stops 54 limit the travel of the feed slide. The old blade is stripped from the slide by the slide's retraction into the magazine. The magazine is intended for use with the razors described and claimed in Specifications 600,277 and 600,278, [both in Group XIV]. Specifications 637,174 and 647,772 also are referred to.

Title: Vehicle detection system
IPC: G08G1/042
Filed: 1963-08-22
Abstract: 1,044,657. Vehicle detection systems. RADIO CORPORATION OF AMERICA. Aug. 22, 1963 [Sept. 12, 1962], No. 33328/63. Heading G4Q. [Also in Division G1X] In an arrangement for sensing the presence of a vehicle by detecting variations in the mpedance of a sensing head, means are provided whereby such variations are slowly offset by changing the value of a second variable impedance coupled to the sensor and whereby variations in a sense opposite to those caused by a vehicle are rapidly eliminated by counter driving the same said variable impedance. The vehicle sensor comprises a coil 10, Fig. 1, embedded in the road surface having a parallel capacitor 11 to form a tuned circuit resonant at the frequency of an oscillator 14 and the changes in sensor impedance are detected by a phase-sensitive circuit 16 in which the change of phase produced in the oscillator signal by the detuning of the resonant circuit produces pulses in one or other of two positions, the phasesensitive circuit being supplied with a reference signal from the oscillator, and having the output from the sensor coil applied through a phase inverter. The operation is described with reference to Figs. 4-6 (not shown), and the waveforms of Fig. 3 (not shown). The arrangement is said to compensate rapidly for impedance changes arising from weather changes and to slowly remove a signal due to a vehicle stationary in the zone so that a subsequent vehicle may be detected. The output due to the sensing of a vehicle operates a load 26 such as a traffic control system and drives motor 28 through a control circuit 22, whereas the output due to impedance variations of the opposite sense driver motor 38 through the control circuit 36 the two motors are connected to the variable impedance through a change-over clutch, and gears of markedly different ratios. A phase detector in which positive and negative outputs represent phase advances or delay having a single output circuit and arranged to drive a single motor in a respective desired direction is described with reference to Figs. 7 and 8 (not shown), and feed back connections are provided to ensure that the motor does not draw current when the motor is not rotating, and to rapidly increase the motor current when rapid adjustment is required.

Title: Improvements in or relating to load lifting arrangements for tractors
Inventor: SHERWEN THEO
IPC: B62D49/02
Filed: 1948-12-29
Abstract: 665,860. Load-handling machines. FERGUSON, Ltd., H. Dec. 28, 1949. [Dec. 29, 1948] No. 33367/48. Class 78 (iii). A scoop arm load handling attachment for use with a tractor of the kind having rear draft links 56 which are raised and lowered by a power lift mechanism, and a device which cuts off the hydraulic supply when the links are fully lifted: has a hydraulic scoop arm operating thrustor 21 connected with the tractor power lift pump, and means for preventing the draft links reaching the cut out position so that the power unit remains in condition to actuate the load lifting device. The scoop arm comprises a pair of booms 4 and a V-shaped member 3 which are both pivoted to the tine frame 13 and to a bracket 1 secured to the front axle, the spacing of the pivot points being such that during tilting the tines are rocked slightly forward relative to the booms 4. A pair of bracing arms 17 secured to the outer ends of booms 4 directly and to the inner ends thereof by brackets 18, are attached, at 19, to an operating rod 20 secured to the thrustor piston rod. In operation, the draft links first pick up a counterbalance weight 62 and, due to the telescopic strut 57 which is the same as that described in Specifications 665,827, 665,904 and 665,905, [all in Group XXXII], they do not reach the cut out position and so allow the power unit to operate the scoop arm. The latch gear tor the tine frame comprises a channel member 25, Fig. 3, secured to the apex of member 3 and forming a guide for a rod 27 which at one end is pivotally secured to the frame by a pin 7 and at the other is provided with a catch 28 which co-operates with a latch 29 controlled by a manually operated cable 34 and a return spring 32. A stop 27B on the rod 27 co-operates with an abutment 25A secured to the channel to limit downward tilting of the tine frame which, after discharge, is returned to its former position by adjustable springs 30, 36. The whole unit is secured to the tractor by quick release pins 22, 5 and 5a to facilitate easy removal, and the tine frame, secured to members 3, 4 by quick release pins 7, 10, is easily replaceable by any other load handling attachment having three similarly spaced attachment points. The valve connecting the thrustor 21 with the hydraulic supply co-operates with a self sealing coupling and is thus quickly detachable. In a modification (not shown), the scoop arm may comprise a pair of booms pivoted to the rear axle of the tractor and the thrustors then act intermediate the ends of the arm. Specifications 470,069, and 541,220, [both in Group XXXI], are referred to.
