Title: Improvements in and relating to combs
IPC: A45D24/04
Filed: 1922-07-27
Abstract: 205,246. Biderman, J. July 27, 1922. Combs, hair.-A comb for cleaning the hair has separate teeth in contact with each other for a portion of their length, the teeth being flat sided and the spaces between them tapering gradually to sharp points. The teeth are preferably mounted so that they are free to spread slightly apart against a resistance, so that the hair is pressed beween them and effectively cleaned. The teeth are preferably curved. The comb comprises a. number of strips 10, Fig. 1, and a number of shorter strips 11 arranged alternately and in contact for the greater part of their length and tapering to points 12. As shown in Fig. 2, the teeth are curved outwardly at one side and inwardly at the other. The strips are connected by flexible rods 20, 21, 22 passing through aligned holes in the strips. The rod 20 passes through the longer strips 10 only and extends into holes in the end pieces 15, and a compression spring 24 surrounds the rod and passes through the holes, pressing outwardly against the end pieces 15. The middle rod 21 extends through the end members 15 and is threaded to receive nuts 23. The spring 24 thus holds the front parts of the strips 10, 11 in contact, while owing to the flexibility of the rods the teeth may be sprung apart by the hair. The front rod 22 has one end free to slide in one of the members 15, the other end being detachably secured to the other end piece by a turned up end seating in a recess 30 and retained by a pivoted clip 27. To clean the comb. the rod 22 is withdrawn and the teeth 11 can then be turned out of alignment with the strips 10, as shown in Fig. 2. The construction may be used for combs intended to be, worn in the hair. A diagonal line 1 across the comb facilitates correct reassembly of the parts. Specification 8890/98 is referred to.

Title: Magnetic tape transport system and motor drive speed control system
IPC: H02P7/288
Filed: 1973-05-02
Abstract: 1423683 Automatic control of speed BURROUGHS CORP 2 May 1973 20837/73 Heading G3R The speed of a magnetic recording medium is kept constant by recording a reference signal on the medium, replaying it from a head spaced a fixed distance from the recording head and comparing the phase of this replayed signal with the reference signal to produce a speed error signal. The error signal is used to control the speed of a driving motor for the medium. Additionally when starting the arrangement a transfer switch is used to connect the speed controller to a source of exponentially decaying voltage until the speed reaches the required level when the transfer switch re-connects the error signal. In the reel to reel tape transport system shown the recording and playback heads HW, HR are spaced apart by a distance S determined from the values of the required speed and the reference frequency used. The magnetic tape is arranged to have two data tracks and a centrally disposed reference track used to record the reference frequency signal in quadrature to the data signals. The starting circuit includes an RC circuit to provide the decaying output voltage shown on line 22 and the threshold switch is controlled by trigger circuits using NAND logic elements. On starting, the motor initially runs up over the required speed and then slows to the required speed until a zero error signal causes the transfer switch to re-connect the output of comparator 9 to the controller 2.

Abstract: 148,989. Ges. fur Nautische Instrumente. June 4, 1917, [Convention date]. Addition to 148,963. Gyroscopic compasses.-Consists in the application of the invention described in the parent Specification to compasses having the axis of azimuth rotation of the steering-indicator or lubber mark unrestrained, the said axis being so connected to the gyro that it does not participate in the elevation motions of the gyro-axis, but moves therewith in a direction at right-angles to the movements of elevation. Fig. 2 shows a compass of the floating type in which the card R is carried by the gyro-casing K, the steering-indicator St being carried by the float chamber B. The centre of gravity S of the gyroscope is below its axis of rotation A. The chamber B carries a stirrup G to which is secured a pin F passing into a slot D between arms P<1> carried by the casing K. The slot extends at right-angles to the plane of the drawing so that the gyroscope can elevate without moving the pin F, hut moves therewith in the plane of the drawing. The auxiliary gyroscope P described in the parent Specification is mounted in a housing r carried by the chamber B.

Title: Skid control system
IPC: B60T8/60
Filed: 1975-05-19
Abstract: 1490278 Skid control systems KELSEYHAYES CO 19 May 1975 [24 June 1974] 21227/75 Heading F2F A skid control system 10 receives wheel speed signals at 12 from a left wheel sensor and at 14 from a right wheel sensor (both may be either front or rear) which are fed to a low and high speed wheel select circuit 20 which outputs the lower wheel speed signal to a wheel speed differentiator and comparator circuit 26 which differentiates the low wheel speed signal and compares the resulting deceleration value with a reference 28, emitting a logical signal at 40 if the wheel deceleration computed by integration exceeds the reference. Circuit 20 also outputs both lower and higher wheel speed signals to a wheel speed differential override circuit 50 which emits a logical signal if the difference between high and low wheel speeds exceeds a reference level. Through OR-gate 48 logical outputs from circuits 26 and 50 control brake release by valve solenoid driver 46 and a modulating valve. Deceleration reference value 28 from reference current generating circuit 30 comprises a combination of currents from first, second and third current sources 32, 34 and 36 respectively. The first 32 generates a current representative of a very low wheel deceleration, the second 34 together with the first a current representative of a wheel deceleration which would occur during an incipient skid condition, and the third 36 generating a current representative of a very high wheel deceleration much greater than maximum non-skidding wheel deceleration. The second current source 34 is controlled by the output 40 from circuit 26 via inverter 38 and the third current source 36 by the output 40 triggering a one-shot multivibrator 42 or alternatively by a reset timer 58 which operates if the duration of the signal from valve solenoid driver 46 exceeds 1À5 seconds to avoid a continuous brake release situation. Sequence of operation.-When the deceleration of the low speed wheel exceeds reference current 28, initially a combination of first and second sources 32 and 34, the output from circuit 26 causes the second source 34 to be switched off and the third source 36 to be switched on for the period of multivibrator 42 (60 to 90 milliseconds) such that the reference 28 will now be greater than the deceleration of the low speed wheel and the output 40 from circuit 26 consequently switched off. Due to the inertia of the modulating valve the duration of the output from circuit 26 will be insufficient to cause brake release unless the wheel deceleration continues to increase exceeding the high reference or the speed differential of high and low speed wheels exceeds the speed reference 52.
